- Abstract:
- Based on four-year field inspection and investigation on deck pavement of mastic asphalt on Jiangyin Bridge, cracking causes of mastic asphalt are studied.Cracks of deck pavement are summarized on crack length and width to get a clear view of their propagations.Traffic surveys including traffic volume, axle load and vehicle speed were also conducted to assess their influences.Samples taken on-site were tested with pulling-out test and fatigue test to benchmark their properties.According to the inspection and tests results, it is concluded that the cracks are induced by rutting and fatigue.Lack of fatigue resistance, not well bonded to the steel deck and insufficient high temperature stability are supposed to be the main reasons as well as high density of low speed, excessively overloaded trucks.
- 通过对江阴大桥浇注式沥青铺装4年的现场调查与跟踪, 研究了浇注式沥青铺装的开裂原因.根据裂缝长度与宽度对其进行了总结以得到裂缝的发展规律.为评估交通荷载对铺装层的影响, 同时进行了包括交通量、轴重、车速等调查.对现场取回的试样分别进行了拉拔试验与疲劳试验以评估铺装层的真实状况.结果表明:铺装层的疲劳抗力与高温稳定性不足、 层间粘结层较弱、低速超载的大交通等是导致铺装层开裂的主要原因.
