| 摘 要： | 透水型沥青路面(OGFC)是一种具有连通空隙的开级配沥青路面材料,具有排水、降噪等良好的功能性.大孔隙沥青混合料的空隙率直接影响到沥青混合料的路用性能和功能性能,而控制OGFC空隙率主要靠确定合理的关键筛孔通过率,但是对于二点通过率与空隙率的具体关系尚无深入研究.文中采用二元线性回归找出OGFC-13的2个关键筛孔通过率与空隙率的关系.研究表明,2.36 mm和4.75 mm两个关键筛孔与OGFC混合料空隙率有很好的线性关系.

| Abstract: | Permeable asphalt is a bituminous mix with very low sand contents resulting in a high air void content.It is promoted as being effective in reducing noise and producing good draining performance at rainy day.The air-void of porous asphalt will influence the pavement performance and hydraulic conductivity of asphalt mixtures,and the controlling of air-void must lean on the passing rate of the key mesh.The research had find the relation between the two key mesh and air-void on OGFC-13 using the method of line... |
