the test road construction specification
Paving site the weather is good, as shown in Figure 3, paving rolling process, the atmospheric temperature at 30 up and down. The final pressure is completed, the newly paved of WMA pavement temperature  at 70-80. Field observations of the test road, WMA can still roll around at 80.
Reclaimer extraction and Marshall test at the scene. The extraction gradation and bitumen content there is little difference with the laboratory test results, Marshall volume indicators and laboratory tests are not very different children. This shows that this Mixing DAT solution add, mixes mixing can be achieved and indoor test approximate mixing effect, even mixing mixing more fully than indoor. Therefore, Marshall Field reclaimer control indicators extracted indicators also can use the standard HMA control.
Work after detection and control indicators
In the first two days after the completion of the test road paving, after detection of the test road workers. The test results are shown in Table 7. The depth of the mean of the test road construction specification requires 1.2 times the mean value of the coefficient of friction of 1.6 times the regulatory requirements, the above layer children almost impermeable meet the specification of HMA.
