由于社会经济的进步和发展,加大了高速公路的车流量,部分高速公路已经达到饱和状态,导致交通拥挤,相关单位为了能够解决高速公路拥挤的状况,拓宽高速公路是较为简单快速的方法。然而高速公路在拓宽的时候,在路面新旧沥青拼接的工程中,新旧路面沥青不能更好的链接,导致这部分路面的密实度低,并且出现渗水的现象,渗水非常严重容易损害路面。对于路面新旧沥青铺设密实的问题,增强路面压实度和提高渗水系数,从而保障沥青路面的质量和效果。
As social and economic progress and development, increase the traffic flow of the highway, some expressways have reached saturation, leading to traffic congestion, the relevant units in order to be able to solve the congestion condition of the freeway, widening the freeway is a relatively simple and quick method. However, when the expressway is widening, the new and old pavement asphalt can not be better linked in the new and old asphalt pavement engineering. As a result, the road surface has low compaction degree and water seepage phenomenon, and the water seepage is very serious and easy to damage the road surface. Asphalt pavement for the new and old laying solid issues, enhance road compaction and improve water seepage coefficient, thus ensuring the quality and effectiveness of asphalt pavement.
