【摘要】 为探讨玻璃的掺入对光催化沥青混合料的影响，文章采用不同玻璃掺量制备光催化玻璃沥青混合料试件，应用路用性能试验和降解汽车尾气试验，测定混合料的高温稳定、低温抗裂、水稳定、抗滑等路用性能指标和降解效率指标，分析了各项指标随玻璃掺量增加的变化规律。结果表明：光催化玻璃沥青混合料的路用性能随着玻璃掺量的增大而逐渐下降，当玻璃掺量为10%时各项路用性能指标仍能满足现行规范的要求，但若玻璃掺量继续增大则低于现行标准；随着玻璃掺量的增加，混合料对汽车尾气的降解效率逐渐提升，当玻璃掺量超过10%后增加的幅度明显减缓；综合考虑路用性能和降解效率要求，建议最佳玻璃掺量取10%。更多还原

【Abstract】 In order to explore the influence of glass incorporation on photocatalytic asphalt mixture, this paper used different glass content to prepare photocatalytic glass asphalt mixture specimens. The road performance test and automobile exhaust degradation test are used to determine the high temperature stability, low temperature crack resistance,water stability, skid resistance and other road performance indicators and degradation efficiency indicators of the mixture. The variation law of each indicator with the increase of glass content is analyzed. The results show that the road performance of photocatalytic glass asphalt mixture decreases with the increase of glass content. When the glass content is 10%, the road performance indicators can still meet the requirements of the current specification, but if the glass content continues to increase, it is lower than the current standard. With the increase of glass content, the degradation efficiency of the mixture on automobile exhaust is gradually improved, and the increase is obviously slowed down when the glass content exceeds 10%. Considering the requirements of road performance and degradation efficiency, it is suggested that the optimum glass content should be 10%.更多还原
