摘要
水泥灌浆沥青砼路面是一种新型的半柔性复合型路面结构,由于水泥胶浆的灌入,使路面兼具沥青砼路面和水泥砼路面的特点,大大改善了路面的高温使用性能.针对半柔性复合型路面20%、25%和30%三种空隙率的基体沥青混合料进行了灌浆前后的马歇尔试验和高温车辙试验研究,验证了半柔性路面良好的高温稳定性能.
The pavement of Portland cement pouring into asphalt concrete is a new semi-flexible composition pavement structure, and the new pavement possesses the characteristics of both asphalt concrete and Portland cement concrete because of the pouring of Portland cement, which improves the performance in high temperature greatly. The Marshall test and Wheel tracking tests are carried on in front of and behind pouring three mother-asphalt-mixture with different gap rates of 20% ,25% and 30%, and the tests prove the high temperature stable performance of semi-flexible pavement.
