摘要
为研究不同类型超薄罩面层的路用性能,按照设计配合比制作试件开展室内试验,并对其高温稳定性、低温抗裂性和水稳定性进行分析。结果表明:Novachip-B的动稳定度最高,高温稳定性最好;UTAC-7破坏时的弯拉应变最大,劲度模量最小,低温抗裂性能最好;Novachip-B残留稳定度和强度比均较高,水稳定性最好。
To study the road performance of different types of ultra-thin overlay,specimens were prepared according to the designed mix ratio to carry out the indoor tests,and the high-temperature stability,low-temperature cracking resistance,and water stability were analyzed.The results show that the dynamic stability of Novachip-B is the highest,with optimal high-temperature stability.The flexural-tensile strain of UTAC-7 was the largest at failure,the stiffness modulus was the smallest,and the low-temperature cracking resistance was optimal.Novachip-B has high residual stability and strength,and optimal water stability.
