Definitions
- the invention relates in particular to a device for checking the compression of black ceilings in road and path construction with a vibratory roller, which is provided with a compression control device.
- Such compression control devices can, for example, on Pulley-mounted pulse transducers that work together with a Accelerometer method with statistical execution function.
- It can be of such an accelerometer on the roller frame but also the impact forces that occur when the vibrating are recorded Bandage of a vibratory roller the surface to be compacted processed.
- the temperature changes between two transitions with one machine in the asphalt layer have a non-compensable Influence.
- the object of the present invention is therefore to provide a device for To further develop compaction control in such a way that Black ceilings in road and path construction provides measurement data and results, which do not have the disadvantages mentioned above.
- the device has a second vibration roller for compaction control, which with a is provided second compression control device and with the first vibratory roller coupled this essentially tracking true is, wherein an evaluation unit is available, the measurement results of the two compaction control devices.
- the invention has the advantage that with the first vibrating roller coupled second vibratory roller the second transition in time so immediately The following is to be achieved between the two transitions lying period with regard to a temperature change in the asphalt layer can be neglected. Furthermore, through the existing evaluation unit, which the measurement results of the two in the first and the second vibration roller associated compression control devices compared, also influences are compensated, if due to the existing measuring depth the stiffness of the under the asphalt layers lying surface is measured proportionately. This The influence of the underground stiffness can be determined by the difference in the measurement results be eliminated in the comparison.
- the invention is also based on the finding that the change the asphalt stiffness is a fairly good reference value for the increase in Progress of compaction of the asphalt is.
- This track-true coupling can most advantageously be done in a tandem roller to reach.
- the vibratory rollers to be provided in two separate single drum rollers, which in particular coupled with each other via a computer-aided tracking process are.
- This computer-aided tracking method for example use of satellite-based global positioning systems (GPS) become.
- GPS global positioning systems
- the two tracked rollers can also be coupled with each other via radar, ultrasound, infrared etc. his. Of course, a rigid coupling via a Pole possible.
- the two compression control devices provided are calibratable, so differences in the To be able to compensate for the measured value recording
- the two vibratory rollers on elements with known ones and / or set up the same dynamic stiffness, for example Blocks of elastic material, and then the resulting Compare measured values.
- the Evaluation unit advantageously also contain a delay element, with which the measurement results of the first compression control device are to be temporarily stored in order to be compared to the identifying location with the measurement results of the second compression control device.
- the holding time of the delay element depends is the driving speed and the distance between the two coupled vibratory rollers.
- FIG 1 you can see a compression device in the form of a known Tandem roller with two vibrating rollers, the outside of the conventional Has structure.
- the compactor has a front roller 1, the front structure 2a is attached to which the driver's cab Tandem roller is located, and a rear roller 3, which is part of the rear Structure 2b, which is also the drive motor of the compactor contains.
- the two bodies are used to steer this tandem roller 2a and 2b connected to one another via an articulated joint 4.
- FIG. 2 shows a sketch in which it can be seen that the front one Roll 1 provided with a first compression control device 5 is, like the second vibrating roller 3, with a second compression control device 6 is provided.
- These compaction control devices 5 and 6 operate in the manner known from earth compaction by they determine the dynamic ground stiffness. You determine in here illustrated example the overall dynamic stiffness of both of them compacted asphalt layer 7, as well as proportionately the stiffness of the underlying, already compacted subsoil 8.
- the determined by the two compression control devices 5 and 6 dynamic overall stiffness are sent as measurement results to an evaluation unit 9 forwarded by the front and rear Compression control device compared measurement results obtained. This is done by comparing the measured stiffness at the front or rear roller the increase in stiffness resulting from the Crossings of the rollers determined. If the increase is small, the compression can the asphalt layer 7 can be assumed to be completed.
- the influence is also determined by forming a difference in the evaluation unit 9 the underground rigidity eliminated.
- the one from the evaluation unit 9 The result of the display device 10 is thus a direct measure of the compaction of the asphalt layer 7.
- This display device 10 may, for example, be a But the pointer instrument indicating the difference in compression also acts a light-emitting diode display, the traffic light-like an adequate or still insufficient compression is signaled.
- Example to compensate for roll specific differences in the control devices also provided calibration elements 11 with which For example, different roller weights can be compensated for.
- To the rest with the display unit 10 that determined with the rollers 1 or 3 To compare the measured value for the same ground location is in the Evaluation unit 9 also integrates a delay element 12. Whose Holding time for the delayed transfer from the front roller 1 determined Measured value depends on the distance between the front Roller 1 and the rear roller 3 and the speed accordingly arrow 13 in FIGS. 1 and 2.
