Asphalt road pavement is the most widely applied road pavement method. Currently, various researches, from structural to material, are actively pursued to secure commonality and reduce maintenance / repair costs. There is a situation. However, in order to secure the applicability of these research results, quality control of the construction site should be preceded. In particular, the void or density of asphalt road pavement material can be called as a factor that greatly affects the serviceability of the asphalt pavement. It is no exaggeration to say that the long-term commonality of road pavement is determined by proper pledge management during construction.

As the current compaction management method, the fracture test method that collects field cores and measures cores while performing road paving at the actual construction site of road paving is most common. However, since the core can be taken when the temperature of the asphalt road pavement falls below 50 ° C, the failure test method has a problem that quality control of compaction density cannot be continuously performed during the construction of the road pavement material.

In order to improve the problems of the compaction management method as described above, equipment for measuring the density of the site during the compaction process of various asphalt road pavement is being developed. In other words, the equipment is proposed to measure the density immediately on the site without destroying the pavement pavement, and to control the quality of the pavement. The proposed compaction density measurement equipment for asphalt road pavement has been made by using a radiation density gauge (Nuclear density gauge) using radiation and a non-nnuclear density gauge (AC) using alternating current (AC) current. .

However, the accuracy of non-nuclear field compaction density measuring equipment is reported to be inferior, and the nuclear field compaction density measuring instrument has been shown to be slightly more accurate than the non-nuclear equipment. There are many shortcomings in the additional areas, such as the need and the risk of radiation leakage.

The present invention has been invented to improve the above-mentioned conventional problems, and has the following technical problems.

First, the present invention has a technical object to provide a measuring method and a measuring system for measuring the compaction density of the asphalt coating and packaging material in a non-destructive manner even with a fairly simple equipment.

The present invention has a technical feature that it is possible to calculate the compaction thickness of asphalt road pavement simply by non-destructive method even with the most basic measuring equipment such as ruler and protractor. Hereinafter, the present invention will be described in detail by dividing the present invention into an on-site compaction density measuring method, a measuring system, and an asphalt road paving method according to the accompanying drawings and preferred embodiments.

1. Method for Measuring Compaction Density in Asphalt Road Pavement

1 is a flowchart showing a method for measuring the compaction density of the asphalt road pavement according to the present invention, with reference to this will be described step by step a method for measuring the compaction density of the asphalt road pavement construction site.

(a) Position measurement

The surface position of the ground plane B is measured before pavement. The surface position of the base surface (B) is used as a reference for calculating the thickness (installation thickness or compaction thickness) of the coating and packaging material (P).

(b) Road paving

The road paving material (P) is installed on the base surface, and the road paving material (P) is preferably installed so that its upper surface is horizontal to secure a certain thickness. In order to secure the construction quality, it is necessary to check whether it is installed with a thickness of more than a certain level. In order to measure the thickness, the position of the surface of the road paving material (P) should be measured.

(c) sample collection

The sample (S) of the road pavement material installed on the base surface (B) is taken and the weight (SW) of the collected sample is measured. At this time, it is preferable to collect the sample at a location close to the measurement site of the road pavement material to reduce the error in density calculation. In other words, the sample (S) for the density calculation under the same conditions is to measure the position. However, for convenience of calculation of the sample (S) plane area, the sample (S) is to be taken in the form of a rectangular parallelepiped, and the weight (SW) of the sample is to be precisely measured by an electronic balance. After the sample (S) is collected, the road paving material (P) is filled in the collected portion so that the road paving is performed as a whole.

(d) Road paver compaction and position measurement

The road paver P laid on the base surface B is compacted with a compactor (roller, R) and the compaction surface position of the compacted road paver P is measured.

(e) Compaction density calculation

The compaction thickness PT of the compacted road pavement material is calculated from the surface position of the base surface B and the compaction surface position of the road pavement material P, and the compaction volume SV of the sample is calculated therefrom, and the compacted volume of the sample ( The compaction density is calculated from SV) and the weight of the sample (SW). That is, the difference between the surface position of the base surface B and the compaction surface position of the road pavement material P will be the compaction thickness PT of the compacted road pavement material, if the sample S is compacted under the same conditions, Since the compaction thickness (ST) will be the same as the compaction thickness (PT) of the compacted road pavement material, multiply the compaction thickness (PT) of the compacted road pavement material by the planar area (SA) of the compacted road pavement material. X PT) will be calculated, and further, if the weight (SW) of the measured sample is divided by the compacted volume (SV) of the calculated sample, the compaction density (SD = SW / SV) of the sample is calculated.

The compaction density (SD) of the sample calculated as above becomes the compaction density (PD) of the road pavement material compacted. However, this is assuming that the thickness of the sample is compacted while maintaining the flat surface when the applied pavement material (P) is compacted. It is possible. As a result, there may be an error between the compaction density (SD) of the actual sample and the compaction density (PD) of the compacted road pavement. Therefore, if the correction factor (k) is found and multiplied by the compaction density (SD) of the sample, the compaction is more accurate. The compaction density (PD) of the pavement can be obtained. The correction factor (k) can be found from the example of the preliminary construction of asphalt road pavement materials with the same mixing conditions or from the test pavement data prior to this construction. That is, the correction coefficient is calculated by comparing the compaction density of the sample at the actual construction site with the compaction density of the core at the preliminary construction example or the test packaging. The above calculation process is as follows.

(Ⅰ) Compaction thickness of sample (ST) 다 Compaction thickness of road paving material (PT)

(Ii) Compaction volume (SV) of sample ≒ Plane area (SA) of sample × compaction thickness of road paving material (PT)

(Iii) Compaction density (SD) of sample = weight of sample (SW) / compaction volume of sample (SV)

다 Compaction density (PD) of road pavement

(Ⅳ) Compaction density (PD) of road pavement material; ≒ Correction coefficient (k) × compaction density (SD) of sample

2. On-site compaction density measurement system for asphalt pavement

Figure 2 is a schematic diagram showing a site compaction density measurement system of the asphalt road pavement according to the present invention, Figures 3 to 5 shows the position measuring device 100 and the sampler 200 applied to the measurement system.

On-site compaction density measurement system of the asphalt road pavement according to the present invention comprises a position measuring device 100, sampler 200, scale 300, arithmetic device 400, and has a position measuring device 100 There is a technical feature that it is possible to measure the compaction density of the road pavement in the field by calculating only the sample (S) of the road pavement material before compaction. That is, even if the core of the road pavement material P is not collected after the compaction, the compaction density of the compacted road pavement material P can be measured by calculation, thereby eliminating the destruction caused by the core collection after the compaction.

Position measuring device 100 is a device for measuring the surface position, in the present invention proposes a position measuring device of the displacement and angle in Figs.

3 shows a displacement position meter, the displacement position meter 100 includes a vertical support 110 provided to stand vertically; A horizontal support 120 coupled to be maintained horizontally on the vertical support; And a mover (scale, 130) coupled to adjust the length vertically downwardly to the horizontal support. However, FIG. 3 (b) shows an example in which the horizontal support 120 is hinged to the vertical support 130 to be rotated. When the horizontal support 120 is finely adjusted, the vertical support 110 is installed. Regardless of the flatness of the place, it is possible to secure the horizontality of the horizontal support. Of course, when the measurement is started with the position measuring device 100 will have to maintain the horizontal level by fixing the horizontal state of the horizontal support (120).

As described above, the displacement position measuring device 100 measures the position of the surface to be measured as the length of the mover 130 at the time when the end of the mover 130 touches the surface to be measured. That is, if the surface position of the base surface (B) before the road paving material (P) is measured, the mover (130) is elongated, and if the surface position of the paving surface (P) is laid after measuring the surface of the ground ( The mover 130 is shorter than when measuring the surface position of B), and if the compaction surface position is measured after compacting the paved road paving material P, the mover than when measuring the paving surface position of the road paving material P 130 is stretched, where each surface position is measured as a change in the vertical length of the mover 130. The measured surface position difference, that is, the vertical length difference of the mover 130 will be the paving thickness or compaction thickness of the road paving material P. As a measuring device for position measurement, the mover 130 may use a displacement measuring magnetic sensor (LVDT), a dial gauge, or the like.

4 shows the angular position measuring device 100 is an angular position measuring device, the vertical support 110 provided to stand vertically; A horizontal support 120 rotatably hinged to an upper portion of the vertical support; And a protractor 140 measuring the degree of rotation of the horizontal support.

The angle position measuring device 100 as described above is to measure as the angle of rotation of the horizontal support (based on when the horizontal support is laid horizontally) when the end of the horizontal support 120 touches the surface to be measured. The position of the surface is measured. That is, if the surface position of the base surface (B) before the road paving material (P) is measured, the horizontal support (120) rotates greatly, and if the surface position of the road paving material (P) after the installation is horizontal, The supporter 120 has a smaller rotation angle of the horizontal supporter 120 than when measuring the surface position of the base surface B, and if the compaction surface position is measured after compacting the paved road paver P, the road paver ( The angle of rotation of the horizontal support 120 becomes larger than when the installation surface position of P) is measured, where the vertical height (h) with respect to the rotation angle is represented by the angle of rotation of the horizontal support (θ) and the length of the horizontal support (ℓ). If we find (h = ℓtanθ), we measure each surface position by that value. The difference in each measured position of the surface, that is, the difference in the vertical height h with respect to the rotation angle of the horizontal support 120 will be the paving thickness or compaction thickness of the road paving material P. As a measuring device for the angle measurement, the protractor 140 may use an electronic or mechanical type.

Whether the displacement of FIG. 3 or the angle of FIG. 4, it is preferable to mount the support weight 121 and the level 122 on the horizontal support 120 in the position measuring device 100, so that the horizontal support 120 is provided. It is possible to make accurate measurement by securing stable horizontal level.

The sampler 200 is a device for collecting a sample of a predetermined standard, and is composed of a cutter 210 and a sampling shovel 220. Figure 5 shows an example of the sampler 200 proposed in the present invention, an example consisting of a square cutter and a forceps type shovel.

The cutter 210 of FIG. 5A includes a vertical square cutter portion 211 formed of four quadrangles, a horizontal portion 212 extending horizontally from the upper portion of the square cutter portion, and a handle portion mounted on the horizontal portion. 213 and the level 214 provided in the horizontal portion are formed as a square cutter. The square cutter 211 serves to cut the road pavement material P installed in the shape of a sample, and is proposed in the shape of a rectangle to easily calculate the planar area of the sample required for the compaction density calculation of the sample. It is suitable that the height is 130 mm while the plane area is 200 mm × 400 mm. The horizontal portion 212 is a configuration provided to protect the sharp square cutter portion 211, and when pressing the square cutter portion 211 when cutting the road paving material (P) installed by the square cutter portion 211. Also serves as. A handle 213 is mounted to the horizontal portion 212 for ease of use, and a level 214 is provided for measuring the horizontality of the horizontal portion 212.

5 (b) is a sampling shovel 220 is configured by the pair of shovels divided into the shovel 222 and the blade 221 so that the shovel 222 is hinged to each other while the blade 221 is arranged to face each other. This is an example formed with a tong type shovel. Such a tong-type sampling shovel is preferable because it can prevent the loss of the sample during the collection process, in order to prevent the spread of the blade 221 at the time of sampling, the connector 223 connecting the shovel 222 to each other It is preferable to prepare.

The balance 300 is provided to measure the weight of the sample S taken from the sampler 200. The present invention proposes an electronic balance capable of accurate measurement.

The calculating device 400 is configured to calculate the density from the input data when the data measured by the position measuring device 100 and the scale 300 are input. That is, since the volume data is secured by the position measuring device 100 and the weight data is secured by the scale 300, the density is calculated by the volume data and the weight data thus secured. The density calculation is the same as the density measurement method described above. As a result, the compaction density measurement of the asphalt road paving material P can be easily performed by the measuring system of the present invention.

3. Road paving method

6 is a flowchart showing an asphalt road paving method using the on-site compaction density measurement system of the asphalt road paving of FIG. 2, with reference to this, a road paving method will be described step by step.

(a) ~ (e) Compaction Density Measurement of Samples

Using the on-site compaction density measurement system of the asphalt road pavement described above, the compaction density of the sample is measured according to the on-site compaction density measurement method of the asphalt road pavement material.

That is, (a) measuring the surface position of the ground surface (B) to be paved before the road paving with the position measuring device 100 in the field compaction density measurement system of the asphalt road pavement; (b) laying road paving material (P) on the ground surface (B); (c) The sample (S) of the road pavement material laid on the ground surface (B) is taken by the sampler 200 in the field compaction density measurement system of the asphalt road pavement, and the weight (SW) of the collected sample is determined by the asphalt road pavement. Measuring with the balance 300 in the field compaction density measuring system; (d) Compacting the road paving material (P) installed on the ground surface (B) with the compactor (R) and the position of the compaction surface of the road paving material (P) from the on-site compaction density measuring system of the asphalt road paving to the position measuring device (100) Measuring; And (e) compaction thickness (PT) of road pavement material compacted from the surface position of base surface (B) and the compaction surface position of road paving material (P) as arithmetic unit 400 in the field compaction density measurement system of asphalt road pavement. Calculating and calculating the compaction volume (SV) of the sample therefrom, and calculating the compaction density (SD) of the sample from the compaction volume (SV) of the sample and the weight (SW) of the sample; It is to secure compaction density (SD). The compaction density (SD) of the sample at this time will be the compaction density (PD) of the road pavement material which is installed and compacted on the actual base surface (B). However, the step (e) may further include the step of correcting the compaction density (SD) of the sample as described in the density measurement method in order to increase the accuracy of compaction density (PD) of the compacted road pavement.

In particular, the step (b) may be configured to further include the step of confirming the installation thickness while measuring the surface position of the road paving material (P) with the position measuring device 100 in the field compaction density measurement system of the asphalt road pavement. In order to ensure proper construction quality, the installation thickness is confirmed.

(f) repetition stage

(D) in the process of measuring the compaction density of the sample (S) until the compaction density (SD) of the sample or a correction result thereof is close to the reference density (BD) of the specimen for the road paving material (P) of the same formulation as the sample. Repeat steps and (e). As a result, the compaction density (SD) of the sample in the compacted state can be known each time the compaction operation is performed. If the compaction density (SD) of the sample is close to the specimen reference density (BD) of the road paver, the road paver is stable. As it can be seen as packed while being compacted, it is possible to secure the desired construction quality according to proper compaction management. Here, the specimen of the road paving material (P) is made of the same formulation as the road paving material actually installed on the site, the reference density (BD) of such a road paving material specimen is determined to the required value by the indoor test.

A simple comparison between the compaction density (SD) of the sample and the reference density (BD) of the specimen may enable the compaction management of road paving materials, but more effectively confirm the proximity of the compaction density (SD) of the sample to the reference density (BD) of the specimen. The compaction rate can be used for this purpose. In other words, the percentage of compaction density (SD) of the sample to the reference density (BD) of the specimen, that is, the compaction density (SD) divided by the reference density (BD) of the specimen and multiplied by 100, is the compaction rate (%). In this case, the closer the compaction rate is to 100%, the closer the compaction density of the sample is to the reference density of the specimen. The formula of the compaction rate can be summarized as follows.

Compaction rate (%) = (standard density (BD) of specimen compaction density (SD) / specimen) * 100

Although the compaction rate can vary according to the construction site conditions of road pavement, according to the construction management of ordinary asphalt road pavement materials, it can be seen that proper compaction is achieved when the compaction rate is 96 to 100%, especially due to the initial traffic load. Considering further compaction, a compaction rate of 98% is most preferred.

Although the present invention has been described in detail with reference to the described embodiments, those skilled in the art to which the present invention pertains will be capable of various substitutions, additions and modifications without departing from the technical spirit described above. It is to be understood that such modified embodiments also fall within the protection scope of the present invention as defined by the appended claims below.
