摘  要:
二灰碎石的骨料外露问题是影响沥青路面不平整的重要因素 ,通过对二灰碎石中骨料振实空隙率确定“基体材料”的含量 ,在路面结构层间加大摩阻结合力 ,采取提高混合料组成设计、加强力学分析 ,以及加大路面结构层间摩阻结合力的具体措施 ,增大路面使用寿命。

摘  要:
Surface angularity of base course made of lime-flyash stabilized aggregate is the most important factor leading to unevenness of bituminous surface course. By determining the contents of basic material in the mixture in terms of the interstitial rate of aggregate and aggrandizing interior friction of the mixture, the proportion and mechanical property of the mixture can be amended. As a result, the pavement’life can also be prolonged.
