摘要
为了研究空隙率对大空隙沥青混凝土力学性能和渗透性能的影响,下文设计不同矿料级配,采用5%油石比成型15.77%、19.21%、22.18%、24.86%等不同空隙率的试件进行马歇尔试验、浸水马歇尔试验、车辙试验、低温弯曲试验、渗透试验分析空隙率对大空隙沥青混凝土技术指标的影响。
In order to study the influence of porosity on the mechanical properties and permeability of large-void asphalt concrete,different mineral gradations were designed in this paper,and the effects of porosity on the technical indexes of large-void asphalt concrete were analyzed by using 5%oil-stone ratio specimens with different porosities of 15.77%,19.21%,22.18%and 24.86%.
