Abstract:To quantify the improvement effect of NovaChip ultra-thin abrasive layer on asphalt mixture, composite specimens were prepared. Flexure-tension resistant performance, fatigue performance, high-temperature stability after water immersion, and anti-loosening performance were evaluated using three tests including the small beam bending test at 15 ℃, three-point bending fatigue test, and modified rutting test. The results showed that after adding NovaChip ultra-thin abrasive layer, the damage load of composite specimens was increased by 36.4% ~ 82.5%. The fatigue life was increased significantly under different stress levels. The dynamic stability was increased by about 10%. Furthermore, the amount of sticky layer spreading showed a quadratic curve variation with the bearing performance, fatigue life, and loosening rate of improved rutting specimens. In summary, the recommended amount of sticky layer spreading was 0.8~1.0 kg/ m2.
