反射裂缝是旧水泥混凝土路面上加铺沥青混凝土路面的关键问题。补强处理后,在旧水泥混凝土路面上加铺玻璃纤维格栅再进行沥青混凝土路面改造是防止反射裂缝的有效措施。从玻璃纤维格栅的基本性能出发,分析了玻璃纤维格栅防止反射裂缝的机理。对施工中旧路病害调查与评定、路面病害处理、浇洒透层油、铺设玻璃纤维格栅、沥青混凝土路面摊铺与碾压等施工工艺进行了详细介绍。
Reflective cracking is the key issue of overlying asphalt concrete pavement on the old cement concrete pavement. Reinforcement treatment, in the old cement concrete pavement plus fiberglass grating and then asphalt concrete pavement to prevent reflection cracking is an effective measure. Based on the basic properties of glass fiber grating, the mechanism of glass fiber grating to prevent reflection cracks was analyzed. The construction of the old road disease survey and assessment, the pavement disease treatment, pouring through the layer of oil, paving the glass fiber grating, asphalt pavement paving and rolling and other construction techniques are described in detail.
