为了消除室内小模型试验与路面实际运行状况的差异,文章通过室内足尺模拟试验有效地评价沥青混合料防裂层的试验方法,系统地研究了加铺塑料格栅防裂层足尺疲劳实验,表明塑料格栅用于沥青路面可以改善沥青混合料抗疲劳特性和有效防止反射裂缝的出现。
In order to eliminate the difference between the indoor small model test and the actual running condition of the pavement, the article fully evaluates the test method of the anti-cracking layer of asphalt mixture by the indoor full-scale simulation test and systematically studies the full scale fatigue test , Indicating that the use of plastic grille for asphalt pavement can improve the anti-fatigue properties of asphalt mixture and effectively prevent the appearance of reflective cracks.
