The dynamic loads imposed by moving vehicles have variations in load magnitude due to the surface roughness of the pavement system and larger dynamic loads than the design loads can affect the pavement performance and life. The purpose of this study was to find the relationships among the pavement surface roughness, variations in moving dynamic vehicle loads, and the performance of the concrete…
In this study, the effects of high temperature on mechanical properties of high strength concrete were experimentally investigated. The effect of elevated temperatures ranging from 20 to 700 °C (68 to 1292 °F) on the material mechanical properties of normal-weight and lightweight aggregate high-strength concrete of 60 MPa grade was evaluated. Tests were conducted on Ø100 × 200 mm (3.94 × 7…
Trr No. 1323 Materials And Construction, pp. 53-60 The use of the Corbett-Swarbrick fractionation procedure for characterization of age-hardening potentials of asphalts was studied. The fractionation procedure was used to separate asphalts into four different fractions (asphaltenes, saturates, naphtene-aromatics, and polar-aromatics), to identify trends in the changes of proportions of these…

Based on the mining case of Dafosi Coal Mine in Shaanxi Province, which is a typical coal mine with extra-thick coal seam, the effects of mining width, buried depth and rock grade on the ground surface deformation and sur-rounding rock stress have been studied by numerical experiments. It is found that both of the ground surface settlement (SS) and Horizontal Displacement (HD) increased with th…
