摘要
不同橡胶混凝土复合路面结构对路面抗冲击性能的影响需深入研究.以橡胶颗粒等体积替代天然砂制备橡胶混凝土,并制备出不同结构的复合路面.基于自由落锤试验,研究了不同结构的复合路面对抗冲击性能的影响.结果表明:抗冲击性能由强到弱依次为上层为橡胶的混凝土复合路面结构,下层为橡胶的混凝土复合路面结构,单层橡胶混凝土路面结构,单层普通混凝土路面结构.可见橡胶混凝土路面结构的抗冲击性能均优于单层普通混凝土路面结构.
Abstract
The influence of different rubber concrete composite pavement structures on the impact resistance of pavement needs to be further studied.In this study,rubber concrete was prepared by replacing natural sand with rubber particles in equal volume,and com-posite pavements with different structures were prepared.Based on free drop hammer tests,the impact resistance of the composite pave-ment with different structures was studied.The results show that the structures with strongest to weakest impact resistance are,in or-der,concrete composite pavement structure with rubber on the top,concrete composite pavement structure with rubber underneath,sin-gle-layer rubber concrete pavement structure,and single-layer plain concrete pavement structure.It can be seen that the impact resist-ance of rubber concrete pavement structure is better than that of the single-layer ordinary concrete pavement structure.
