摘要
虎门大桥引道大修工程,首次大面积采用了SAWFTL应力吸收层技术。SAWFTL应力吸收层具有高弹粘性、抗疲劳抗塑性变形能力强、密实、不透水等特点,能有效减少或缓解旧水泥混凝土板传递给沥青面层的反射裂缝,并能提高沥青路面的抗水害能力,延长沥青路面的使用寿命。
Technology of SAWFTL stress absorbed layer is firstly widely adopted in approach repair project of Humen Bridge, which has lots of characteristics such as high elasto-viscosity, high fatigue resistance and high resistance of elastic-plastic deformation, dense, watertight etc., so as to reduce or relieve the reflection cracks of asphalt surface transferring from original concrete plate and increase the ability of resisting water trouble and prolong the service life of asphalt pavement
