半柔性路面是一种开级配沥青混合料中灌入水泥浆形成的兼顾沥青路面与水泥混凝土路面特点的复合路面。半柔性路面路用性能具有优良的高温稳定性、耐疲劳性能和水稳定性等优点,通常用于停车场、机场、道路平交路口、爬坡路段及集装箱码头等。传统的半柔性路面在灌入水泥浆后需2~3天养生时间,使得混凝土在完成终凝后具有50%的强度;但在云南多数山区二级公路施工中,因车流量大,无法封闭交通来进行养生,施工完成后即时养生后开放交通,为解决此实际生产需求,对半柔性路面快速通车的关键技术进行了研究,并实地铺筑了试验路段。
Semi-flexible pavement is a kind of open pavement asphalt mixture filled with grout to form a composite asphalt pavement and cement concrete pavement characteristics. Semi-flexible pavement performance with excellent high temperature stability, fatigue resistance and water stability, etc., are commonly used in parking lots, airports, road junctions, climbing sections and container terminals. The conventional semi-flexible pavement needs 2 to 3 days to maintain after the grout is poured, which makes the concrete 50% strength after finishing the final setting. However, in the construction of the second grade road in most mountainous areas in Yunnan, traffic can not be closed due to the large traffic flow To carry out health maintenance, after the completion of the immediate health care after the opening of traffic, in order to solve this actual production needs, the semi-flexible pavement rapid opening of the key technologies have been studied and paved the experimental road.
