陶瓷沥青混合料路用性能试验研究
|
摘要
为解决大量废陶瓷堆积带来的环境问题,同时为提高沥青路面的抗滑性能,采用耐磨性能较好的陶瓷再生集料等体积取代部分石灰岩集料(替代率分别为0%、20%、40%和60%),研制陶瓷沥青混合料,开展陶瓷沥青混合料的路用性能研究,主要包括配合比设计、高温稳定性、水稳定性能,以及力学性能研究。试验结果表明:当陶瓷掺量不超过60%时,陶瓷沥青混合料的动稳定度,浸水残留稳定度,冻融劈裂强度比等各项性能指标均满足规范要求,路用性能良好。
In order to solve the environmental problems caused by the accumulation of waste ceramics, at the same time to improve the skid resistance performance of asphalt pavement, the better wear-resisting property of ceramic recycled aggregate is used to replace the partial limestone aggregate(the replacement rate are 0%,20%, 40%, 60% separately) to develop the ceramic asphalt mixture. The pavement performance study of ceramic asphalt mixture is carried out mainly including the study of mixture ratio design, high temperature stability, water stability and mechanical property. The results indicate that when the ceramic content is not more than 60%, the dynamic stability, the stability of the residual water, the ratio of freezing thawing splitting strength and other performance indicators of ceramic asphalt mixture meet the requirements of the standard,and its pavement performance is good.
