GTM法在高速公路沥青路面大修工程中的应用

石太高速沥青路面大修工程中，针对路面重载交通量大、车辙病害严重的特点，为提高路面的抗车辙能力，首次采用GTM法进行沥青路面设计。在施工控制过程中，适当提高了对路面集料的质量技术要求，并严格施工工艺质量控制，采用大吨位胶轮压路机增加压实功，保证了压实密实度达到设计要求。大修竣工通车四年来，路面平整密实，使原来非常突出的沥青路面车辙病害得到根治。

Application of GTM Method in Expressway Asphalt Pavement Overhaul Engineering

In Shijiazhuang-Taiyuan expressway asphalt pavement overhaul engineering, in allusion to the characteristics of heavy overloading and serious rut, GTM method is applied in asphalt pavement for the first time in order to enhance the rut-resistance of pavement. During the control of construction, the technical requirement of pavement aggregates is heightened properly, the technique quality is controlled strictly, and large-tonnage rubber-tyred rollers are used to increase compaction work. The above measures e...
