摘要:
This paper presents an experimental study on the damage and failure model of a new type multi-layer pavement system under drop weight impact. Such a composite pavement consists of three layers including asphalt concrete at the top, high strength concrete in the middle, and engineered cementitious composites at the bottom. The aim is to quantify the extent to which the multi-layer composite improves the resistance of protective pavements against impact load. The large scale drop weight tests were conducted on multi-layer composite pavement samples to study their response and performance under impact loading. Conventional rigid concrete pavement and flexible asphalt pavement were also tested to identify the advantages of the multi-layer composite pavement system. The impact resistance of three different pavements is evaluated in terms of the extent of damage, failure mode, deformation, and accelerations against double impacts. The test results show that the multi-layer composite pavement system exhibits less damage, significantly improved impact resistance against double impacts and improved ductility and energy absorption capacity compared with both conventional concrete and asphalt pavements. © 2017, Editorial Board of Journal of Tianjin University(Science and Technology).
