INDOOR TRACK FOR TESTING PAVEMENTS UNDER CONTROLLED ENVIRONMENT

As an intermediate step between laboratory testing and full-scale in-service test sections, the Saskatchewan Department of Highways and transportation constructed an indoor track for testing pavement design concepts and materials under controlled environment. The circular test track is 38 M along centre-line and 3.6 M width. Any combination of subgrade and pavement to a depth of 1.25 M can be constructed. The loading system is an electrically-driven twin I-Beam gantry capable of carrying full-size single or dual wheel assemblies. A force up to 55 kn can be applied to a pavement surface at speeds up to 10 m/s. A computer controlled array of sensors to monitor temperature, deflection, rut depth, stresses, and strains comprises the data acquisition system. Portions of the test track can be subjected either to wet-dry cycling with open or closed water systems or to two-directional freeze-thaw cycling. Design, construction and operational aspects of the test track are described. (TRRL)
