PROBLEM TO BE SOLVED: To correctly comprehend/evaluate the quality characteristics and deterioration durability strength of pavement material in a test environment where a running wheel load actually acting on a paved road is correctly simulated by executing a wheel tracking test standing on the actual condition of positional variation in a wheel running track of a vehicle that travels the paved road.;SOLUTION: A test wheel compared to the wheel of a vehicle traveling on a paved road is caused to repeatedly travel a number of times on a test specimen equipped with a structure of the same quality as a paved road under test and compared to the paved road under test. The test wheel is caused to travel along the same rectilinear track in a traveling direction X. With the test wheel apart from the test specimen after having traveled on the test specimen, the test specimen is moved to and positioned at a moving position changing in a moving direction Y different from the traveling direction X of the test wheel while randomly controlling the moving position and the occurrence frequency of the moving position according to a normal distribution characteristic. After the movement and positioning, the test wheel is caused to proceed to next traveling on the test specimen.;COPYRIGHT: (C)2006,JPO&NCIPI
