随着经济的不断发展,高速公路的交通压力也越来越大,因此,高速公路隧道的水泥路面也一定程度上受到了损害。一些使用较久的公路隧道损害的程度会比较严重,因此也就无法满足目前的交通需求,故而要使用“白改黑”改造技术,在援用基础上加设沥青混凝土面层。对此,本文将简述关于某高速公路的“白改黑”道路施工及养护技术。 As the economy continues to develop, the traffic pressure on expressways is also growing. As a result, the cement pavement of expressway tunnels has also been damaged to some extent. Some of the more prolonged use of road tunnels will cause more damage. As a result, they will not be able to meet the current traffic demand. Therefore, we need to use the “white to black” conversion technology to add asphalt concrete pavement on the basis of assistance. In this regard, this article will outline a highway about “white to black” road construction and maintenance technology.
