Embodiment 1
[0064] According to the T0703 asphalt mixture specimen preparation method (wheel rolling method) in the highway engineering asphalt and asphalt mixture test regulations (JTG E20-2011), the dense asphalt concrete AC- 13 gradation standard, using basalt aggregates to make asphalt concrete slabs. Further apply a self-regulating asphalt concrete thin layer overlay (such as figure 1 shown), the specific steps are: configure the self-regulating asphalt concrete thin-layer overlay material according to the formula in Table 2, and coat the self-temperature-regulating asphalt concrete thin-layer overlay material on the surface of the asphalt concrete slab with a thickness of about 10mm, and Sprinkle gravel evenly on the concrete overlay material, remove unbonded gravel after curing, and prepare the control group and experimental groups 1-3. The control group and the experimental group were tested for performance. Specifically, the control group and the experimental group were immersed...
Embodiment 2
[0070] According to the T0703 asphalt mixture specimen preparation method (wheel rolling method) in the highway engineering asphalt and asphalt mixture test regulations (JTG E20-2011), the dense asphalt concrete AC- 13 gradation standard, using basalt aggregates to make asphalt concrete slabs. Further apply a self-regulating asphalt concrete thin layer overlay (such as figure 1 shown), the specific steps are: configure the self-regulating asphalt concrete thin-layer overlay material according to the formula in Table 4, and coat the self-regulating asphalt concrete thin-layer overlay material on the surface of the asphalt concrete slab with a thickness of about 10mm, and Sprinkle gravel evenly on the concrete overlay material, remove unbonded gravel after curing, and prepare experimental groups 4-9. Performance tests were performed on the prepared experimental groups, and the performance of each experimental group was similar to that of the implementation groups 1-3.
