采用GSOG白加黑技术,在旧水泥混凝土路面上加铺GSOG沥青混合料,可有效延缓和预防旧水泥混凝土路面反射裂缝的扩展,满足交通密度高和重载交通等路况需求。根据衢州市上下街旧水泥混凝土路面情况和衢州市市政规划需求,在改造工程中采用了GSOG白加黑技术,即在旧水泥板块上加铺GSOG-20沥青混合料,取得了成功。这对于GSOG白加黑技术在中小城市道路中的应用和推广具有重大意义。 Using GSOG white and black technology, adding GSOG asphalt mixture on the old cement concrete pavement can effectively delay and prevent the expansion of the reflective cracking of the old cement concrete pavement, and meet the traffic density and traffic conditions such as heavy traffic. According to the situation of Qujiang Shangjie Street, the old cement concrete pavement and the municipal planning of Quzhou City, GSOG white and black technology was adopted in the renovation project, that is, GSOG-20 asphalt mixture was added to the old cement board and achieved success. This is of great significance to the application and promotion of GSOG white plus black technology in small and medium-sized urban roads.
