为了证明使用BMA制备SMA-13混合料是否具备可行性,本文通过室内试验、示范路铺筑和资料调研等手段,研究BMA改性SMA-13混合料的路用性能,总结示范道路的铺筑过程与检测结果,并分析该混合料的应用前景。结果表明:BMA改性SMA-13混合料的路用性能均满足规范要求;示范道路的铺筑进一步验证了使用BMA配制SMA-13混合料的可靠性;BMA改性SMA-13混合料的生产成本比SBS降低30元/t,具有很好的社会、经济和环境效益。
In order to prove whether it is feasible to prepare SMA-13 mixture by BMA, this paper studies the road performance of BMA modified SMA-13 mixture by means of laboratory test, demonstration road pavement and data research, summarizes the paving of demonstration road Process and test results, and analyze the application prospects of the mixture. The results show that the road performance of BMA modified SMA-13 mixture meets the requirements of the specification. The demonstration road pavement further verifies the reliability of BMA-formulated SMA-13 mixture and the production of BMA modified SMA-13 mixture The cost is 30 yuan / t lower than SBS, which has good social, economic and environmental benefits.
