ALF是英文缩写,即加速加载设备.它是一种移动式的公路路面加载系统,可对路面施加可控制的滚动轴载,并可在较短时间内,较真实地模拟出实际交通荷载几年内对路面的破坏作用,我国于1989年购进这种设备,成为世界上继澳大利亚和美国之后拥有这种大型综合试验设备的第三个国家。交通部公路科研所和河北省交通厅合作,于1990年3月在河北正定京深高等级公路进行了三种路面结构的加速加载试验,1991年4月起在河北涿州京深高等级公路的慢车道和快车道进行两种结构不同轮荷的试验,均取得满意结果.
ALF is the acronym for accelerated loading equipment.It is a mobile highway road surface loading system that can be applied to the road roller bearing controllable and can be a relatively short period of time, more realistic simulation of the actual traffic load a few During the year, it destroyed the pavement. China purchased such equipment in 1989 and became the third country in the world possessing this kind of large comprehensive testing equipment after Australia and the United States. Highway Research Institute of Ministry of Communications and Hebei Provincial Communications Department, in March 1990 in Hebei Zhengding Beijing-Shenzhen high-grade highway accelerated loading test of three pavement structure, in April 1991 in Hebei Zhuo Jing-Sheng Highway Slow lane and fast lane for two different structure of the wheel load test, have achieved satisfactory results.
