| 摘要： | New Zealand pavement design and construction practices are significantly indigenous, having evolved to suit the local conditions. Asphalt-bound aggregate systems are used for some urban streets and interurban motorways, and some rigid pavements were constructed 50 years ago, but virtually all highway traffic is carried by thin-surfaced unbound granular pavements. The need to ensure that designs and materials are adequate for modern vehicles provided the impetus for developing an accelerated pavement testing facility that reproduces vehicle dynamics. First, the development of the Canterbury Accelerated Pavement Testing Indoor Facility (CAPTIF) is described. The main feature of CAPTIF is the Simulated Loading and Vehicle Emulator, which can apply a myriad of loading conditions via an array of tire and load configurations at high rates of accelerated loading. Second, research projects conducted since 1986 are discussed and the significant results are presented. The research conducted at CAPTIF has contributed to the understanding of the behavior and performance of thin-surfaced, unbound granular pavements and the effect of vehicle dynamics on pavement wear. |
