大碎石沥青混合料施工级配与空隙率变异性分析

Analysis on the variability of construction gradation and void ratio of LSPM

通过大碎石沥青混合料的级配变异性以及现场空隙率变异性分析研究,得出大碎石沥青混合料应从原材料、取样方式、试验方法及过程工艺等多方面联合控制,降低施工的变异性,实现LSPM沥青混合料良好地排水等路用性能。

This paper analyzes the variability of LSPM gradation and on-site air voids variability. It concludes that large aggregate asphalt mixture should be controlled from raw materials, sampling methods, test methods and process technology, so as to reduce the construction variability and realize the excellent road performance of LSPM.
