摘　　要：半柔性路面是一种在大空隙沥青混合料(15%~30%)中灌注水泥基材料而形成的一种刚柔并济的路面形式。为了探究磷酸铵镁水泥作为灌浆材料制备的半柔性路面的路用性能,对不同空隙率的大空隙沥青混合料中灌注磷酸铵镁水泥灌浆材料,制备了不同空隙率的半柔性试件,并对其进行了水稳定性、低温抗裂性能以及高温抗车辙性能测试。试验结果表明:随着沥青混合料空隙率的增大,半柔性试件水稳定性及高温抗车辙性能提高,低温性能下降。Semi-flexible pavement is a form of pavement that combines rigidity and flexibility,formed by pouring cement-based materials into a large void asphalt mixture(15%~30%).In order to explore the pavement performance of semi-flexible pavement prepared with ammonium phosphate magnesium cement as grouting material,ammonium phosphate magnesium cement grouting material is poured into the large void asphalt mixture with different voids,and semi-flexible specimens with different voids are prepared,and the water stability,low temperature crack resistance and high-temperature rutting resistance are tested.The test results show that:with the increase of the void fraction of asphalt mixture,the water stability and high-temperature rutting resistance of the semi-flexible specimen increase,while the low-temperature performance decreases.
