一、概述由于路面结构属开放体系,受环境因素影响较大,而且随着交通量的不断增长以及车辆轴载的增加,对路面结构的作用变得更加复杂。为此,单纯用室内试验来研究路面材料、结构性能,就存在着一定的局限性,不能与路面的实际受力状况相符合。而足尺加速加载设备能对正常施工的路段施加仿真的轮载,并通过重复地对路面结构施加足尺的移动轮载来迅速判定路面的性能,这样就可用某种程序对新设计方法、沥青混合料、改性材料、技术革新和理
I. Overview Since the pavement structure is an open system, it is greatly affected by environmental factors. As the traffic volume increases and the axle load of the vehicle increases, the effect on pavement structure becomes more complicated. Therefore, simply using laboratory tests to study pavement materials, structural performance, there are some limitations, can not be consistent with the actual road surface conditions. A full-scale accelerated loading device, on the other hand, imposes a simulated wheel load on a section of normal construction and quickly determines the performance of the road surface by repeatedly applying a full-scale moving wheel load to the pavement structure so that a program can be used to evaluate the new design method, Asphalt mixes, modified materials, technological innovation and management
