| 摘 要： | 半柔性路面是一种在大孔隙沥青混合料中填充水泥胶浆而形成的兼具沥青路面与水泥砼路面特点的复合路面.笔者采用浸水马歇尔试验和冻融劈裂试验评价半柔性路面混合料的水稳定性,用低温劈裂试验评价半柔性路面混合料的低温抗裂性能.试验结果表明,半柔性路面混合料具有优良的水稳定性、低温抗裂性能.

| Abstract: | Semi-flexible pavement is generally described as an open-graded asphalt concrete mixture,which is filled with Portland cement grout.It is a composition pavement that owns an unique combination of asphalt concrete and Portland cement concrete materials in the same layer.The retain stability and improved Lottoman test were used to measure the water susceptibility of semi-flexible pavement mixture.The split test was carried out to measure the crack resistance at low temperature.The results show that the semi-flexible pavement mixture has better water susceptibility and crack resistance performance. |
