Definitions

  • Embodiments of the present invention relate to a method for compaction control, a measuring system for compaction control and a compaction or rolling device with a corresponding measuring system.
  • the invention is in the field of roll / roll devices and full-coverage compaction control (FDVK) of rolls.
  • the compaction state of each square meter of the compacted area is measured and documented. For this purpose, measurements are carried out continuously during the compaction process.
  • the roller driver can read the current result directly on a display unit arranged in the driver's cab and immediately hand over a FDVK protocol to the construction management or construction control.
  • stored areas and individual tracks can be retrieved at any time in the roller. This allows, for example, an inspection of areas by the construction management or external monitoring directly on site or quick decisions on how to proceed.
  • the FDVK presupposes a compaction meter arranged on the roller or on the compacting device as well as a calculation unit for the storage, analysis, documentation and representation of the measured values.
  • the compaction meter can be, for example, a sensor (acceleration sensor) arranged on the roller drum, which measures the forces acting on the substrate by the roller. The sensor signals change in the course of compaction when, for example, the ground becomes harder and more stable.
  • CMV Compaction Meter Value
  • the compaction measured value CMV is a dimensionless relative value which describes the compaction state of the subgrade at the time of unrolling and whose magnitude varies with the rigidity of the subgrade.
  • the CMV value increases as the number of transitions across a layer to be densified increases.
  • the absolute value of the CMV value and the growth rate of the CMV value The values of transition to transition mainly depend on the size of the roller and the properties of the material or base to be compacted. If the CMV value remains unchanged even after repeated transitions, the corresponding section is fully compacted or can not be compressed further with the relevant roller. The CMV value can also decrease, for example if the background has been loosened by too many transitions. Depending on whether the required compaction result has been reached or not, the compaction work can be terminated or further measures must be taken (eg change the roller, let the material dry out, material exchange, etc.).
  • a disadvantage of the known system is that the CMV value is always displayed as an absolute value and for this purpose a correlation between the CMV value and one either in the laboratory or by, for example, a Troxlond probe (also called “isotope probe", radioactive measuring system according to the manufacturer Troxler Electronic Laboratories USA) measured compaction of the subsurface must be calculated.
  • the procedure requires the performance of a test track with the same material and machine as intended for the construction work. For every other machine, for example, a new test track has to be prepared. After each crossing the compaction is determined by sampling or by means of a Troxi probe in several places, whereby the evaluation of the taken samples takes place in the laboratory.
  • the procedure described is usually very time consuming and is therefore usually performed only for the Bauabddling.
  • a disadvantage of this approach is that no comprehensive measurement of the compaction takes place and thus either insufficient compaction (so-called sub-compaction) or excessive compaction (so-called over-compaction) of the asphalt takes place. This Using the example of a paved road often lead to premature wear of this road or the road surface.
  • the disclosure DE 10 2010 054 755 A1 a method and system for compaction measurement of a first and second depth range of a material.
  • the measured compaction values are displayed in color during the rolling process as a function of a desired degree of compaction (nominal value) on a display system.
  • the two depth ranges are shown, for example, in blue and red color, starting from the desired degree of compaction indicate darker color shades a stronger compression and lighter shades a lower compression.
  • the DE 699 06 803 T2 discloses a method and system for the prediction of compaction quality, wherein first material density values are measured after at least a first and a second pass through a compaction machine. From the measured values, a compression response curve is then determined, from which then a still required number of compression passes is predicted, so that a desired density of the material is achieved.
  • the DE 29723171 U1 a roller device for compacting asphalt pavements, comprising two sensors spaced apart from each other on a suspension parallel to the axis of the roller body for measuring the distance to the asphalt surface.
  • One sensor is arranged in the area of the roller track and the other outside the area of the roller track. The difference between the measured values of the two sensors is a measure of the increase in compaction at the respective roller transition.
  • the object of the present invention is to provide a concept which enables an improved real-time evaluation or a generally improved evaluation for the compaction control.
  • Embodiments of the present invention provide a measuring system for compacting a covering, eg in road construction, for a compacting device or a roller device.
  • the compacting device comprises at least one compacting element, such as a (vibrating) plate or drum / drum, which compresses the lining by weight and / or vibration.
  • the measuring system comprises a compaction sensor, a position evaluation unit and a measured value evaluation unit.
  • the compaction sensor which can be realized for example by a vibration sensor and is arranged, for example, at the bearing of the bandage of the roller device (compression device), is designed to accelerate the compacting element as a result of the vibration (the bandage) or, alternatively, to accelerate a measuring probe as a result of an induced measuring vibration determine over the time course and output a measurement signal associated with the determined acceleration.
  • the position evaluation unit which is for example connected to a position sensor, is designed to determine, based on suitable position information over the time profile, a movement path of the compression device and to associate the measurement signals over the time profile of the movement path.
  • the measured value evaluation unit is designed to determine a change in a compression of the coating for each measurement signal on the trajectory.
  • the invention is therefore based on the finding that, in contrast to the systems known in the prior art, the force effects or, to be precise, a vibration or measuring vibration, are measured or monitored on the planum to be compacted / rolled and starting therefrom the changes in the degree of compaction or the measured force are determined or displayed, wherein the representation per point / position takes place on the trajectory.
  • the changes or changes below the subgrade and thus potential weaknesses in the subgrade (under or overcompaction) during the compression process are immediately recognizable.
  • such smallest changes are detected immediately, which makes a complex calibration or test track structure no longer necessary.
  • This invention has further positive effects. So it is possible in a simple manner, early to detect points below the subgrade, at which a compaction of the subgrade is impaired. This will allow appropriate measures to be taken before the completion of the work, which will maximize the quality of compaction. Concurrently, the compaction work is reduced to the bare essentials and therefore material is spared and costs reduced.
  • a classification of the movement path into a first group if the change in the compression of the lining is minimal, in this first group, no further rolling is required.
  • a classification into a second group takes place when the change in the compression of the lining is large, wherein in this second group further rolling is necessary.
  • a classification of the movement path into a third group can take place if this change in the compression of the lining is negative.
  • the change in the compression lining is considered relative to corresponding embodiments.
  • the so-called delta CMV is determined. This is done, for example, in that a difference formation an absolute compression (CMV before ) of the coating before compression or at the beginning of compacting and an absolute compaction of the lining after compaction (CMV after ) is determined.
  • CMV before absolute compression
  • CMV after absolute compaction of the lining after compaction
  • the measurement can be performed or by a separate element (called measuring probe here) a so-called measurement vibration can be generated.
  • the position evaluation unit may, according to further embodiments, also be equipped with a position sensor, e.g. Part of the measuring system is connected. This offers the advantage that the system is autonomous, i. without obtaining data from the vehicle is functional.
  • the measuring system also comprises additional sensors, e.g. a communication unit or a temperature sensor, which are typically all connected via an interface with the rest of the measuring system. Via the communication unit, data can be exchanged with other roller devices in use or with a control center, which then monitors or records the work progress.
  • additional sensors e.g. a communication unit or a temperature sensor
  • the communication unit Via the communication unit, data can be exchanged with other roller devices in use or with a control center, which then monitors or records the work progress.
  • This o.g. Interface is therefore important because the measuring system can be flexibly integrated into different rolling devices.
  • the above-mentioned temperature sensor is advantageously used according to embodiments for monitoring the temperature of the coating being rolled, so as to improve the evaluation of rolling.
  • the measuring system may also include a display, by means of which the change in the compression of the lining along the movement path is displayed.
  • the display can also show the display of the absolute compression and also other values, such as the coating temperature or the number of rolling processes per position.
  • the roller operator it is now possible for the roller operator to judge whether further rolling is necessary.
  • the graphical representation can be chosen so that the groups explained above emerge directly from the graph. This embodiment based on the real-time evaluation is advantageous because it improves the rolling work in terms of efficiency and quality.
  • roller device per se, which typically comprises at least one, but preferably two, rollers or bandages and wherein the measuring system is then integrated directly into the roller device.
  • Further embodiments provide a method for the compaction control of the lining.
  • the method comprises the steps of "determining an acceleration of a measuring probe as a result of a measuring vibration and / or an acceleration of the rollers due to the vibration of the roller over the course of time” and “outputting a measuring signal associated with the determined acceleration”, “determining a movement path of the compacting device of obtained position information on the time course “and” assignment of the measurement signals over the time course of the movement path "as well as” determining for each measurement signal on the trajectory of a change in the compaction of the coating ".
  • the step of classifying the change in the compaction of the lining into the three groups explained above can then also take place as a function of these five basic steps. This makes it possible in a simple manner, early to detect points below the subgrade, at which a compaction of the subgrade is impaired. This will allow appropriate measures to be taken before the completion of the work, which will maximize the quality of compaction. Along the way, we reduced the compaction work to the essentials and thus spared material and costs lowered. Further embodiments relate to a computer program which carries out the corresponding method.
  • Embodiments of the present invention relate both to roller devices with (vibrating) bandages as compression devices, but also to vibratory plates for compression.
  • Fig. 1 shows a roller 10 for compacting a subgrade 30, with a driver's station 70 and two bandages 50 and 60 in the front and rear of the roller 10.
  • the roller 10 moves on the surface 20, preferably in individual Lanes forward and back to bring about a uniform or area-wide compression of the substrate 30.
  • the substrate 30 may be an asphalt layer or the like with an additional layer 40 underneath.
  • the bandage 50 can be acted upon by a vibration, so that corresponding vibration vibrations 80 penetrate into the soil and compress the substrate 30 accordingly when crossing the roller 10.
  • the strength of the vibration or the amplitude and frequency of the vibrations is adjustable.
  • an FDVK system typically includes a compaction sensor, e.g. is arranged at the bearing of the roller 50/60.
  • the sensor signals of the acceleration sensor can be analyzed in the frequency domain.
  • the dimensionless CMV value (compaction meter value) is proportional to the amplitude of the first harmonic, relative to the amplitude of the exciter frequency. This means that the CMV value is always determined as a function of the excitation frequency or represents a ratio between the determined amplitude and the generated amplitude. From this it is clear that with increasing absolute compression at one point, this ratio shifts, so that it can be concluded from this ratio on the absolute compression. Expressed in reverse terms, this means that the CMV value is a measure of the absolute compression, whereby no reference is made here to the total possible absolute compaction of the coating, but on the achievable with this roller 10 compaction.
  • Fig. 2a shows a compaction measurement system 15, which includes a compaction sensor 150 and a calculation unit 120 with the components of the position evaluation unit 120a and measured values evaluation unit 120b.

  • the measuring system 15 it is assumed that it is mounted on a rolling device with a roller for road construction, wherein the roller compacts the lining by vibration while it moves along a movement path.
  • This movement path can be determined, for example, by determining a multiplicity of position information over a time course.
  • This position information e.g. determined by means of a GPS or GNSS sensor, a total station or another 2D or 3D position sensor, or also generally determined on the basis of the travel speed (or rotational speed of the drum and / or steering angle) of the roller, are determined via the position Evaluation unit 120a obtained (see dashed line).
  • the system may optionally or alternatively be "coupled" to the vehicle / vehicle bus to obtain position information therefrom.
  • a so-called Kalman filter can then be used to calculate a continuous change in position of the roller when e.g. there is no GNSS / GPS sensor or if a stable GNSS / GPS signal is not available due to passage through tunnels or under bridges. Once a GNSS / GPS signal is stable again, it can be used again for the position determination.
  • the measured value evaluation unit 120b receives from the compaction sensor 150 measurement signals which permit a conclusion about the actual acceleration of the roller (due to the vibration of the roller).
  • the series of measurement signals over the time course thus allows to determine how the acceleration behaves along the trajectory.
  • the temporal course of the measurement signals is then assigned to the time profile of the position information.
  • the acceleration during the compaction process changes per point of the trajectory. This change in acceleration indicates the change in the horizontal force on the planum and thus to a change in the degree of compaction.
  • the change in the degree of compaction per point or per rolling along the trajectory makes it possible to draw a much better conclusion on the compaction itself than just the absolute value alone.
  • the change in the degree of compaction can be determined by deriving the CMV value with time or by subtracting the initial and the resulting compaction.
  • a very small change can be interpreted as meaning that no further compaction of the subsurface can be achieved.
  • a major change leads one to conclude that the subsoil can still be densified considerably or that it still has to be heavily compressed in order to maintain a load-bearing road surface.
  • a third example is when even a decrease in compaction can only be effected as a result of frequent rolling.
