MECHNICAL RESPONSE OF BITUMINOUS MIXTURE UNDER VARIOUS LOADING CONDITIONS

This paper describes the test results concerning the mechanical response of bituminous mixtures which are required in rational designing and performance studies of pavement structures. A stress-strain relationship of bituminous mixture was investigated under various loading conditions at various temparatures. A relaxation modulus under the constant rate of strain was computed from the stress-strain curve as a function of loading time. In the flexure test, mode of fracture, relation between flexural is one of the primary factors in the pavement performance. In this study, simulated wheel tracking test was carried out. The systematic relationships between the resistance to deformation and moving speed, tire contact pressure, temperature and binder property were obtained. And also the ductile fracture zone (2 to 5 x 0.01), in the brittle fracture zone (1 to 2 x 0.001) and at the transition point found. This result may shows a difference between static and dynamic test on the flow properties of the mixture. A kneading action caused from the wheel passage was briefly discussed. An electro-hydraulic apparatus was developed to investigate the dynamic response and the fatigue properties of the bituminous mixture, and the dynamic response under the programmed strain wave was discussed. /AUTHOR/
