摘要
基于长效耐久沥青路面技术需求增加,传统的半刚性基层应力吸收层很难满足长寿命路面结构性能的现状,针对沥青砂防水应力吸收层进行配合比设计及施工工艺研究,确定材料的技术要求、配合比及施工工艺,其结果对于沥青砂防水应力吸收层的合理应用具有工程参考价值.
Abstract
Based on the status quo that the demand for long-lasting and durable asphalt pavements increases,and the traditional semi-rigid base stress absorbing layers are difficult to meet the structural performance of perpetual pavements,for asphalt sand waterproof stress absorbing layers,the mix proportion is designed,and construction process is studied to determine the technical requirements,mix proportion and construction process of the materials.The results have engineering reference values for the reasonable application of asphalt sand wa-terproof stress absorbing layers.
