Abstract: Based on asphalt pavement design theory and criterions in China, and referring to successful long life asphalt pavement structures in foreign countries, the stress-strain data in different depths were calculated by using ...

Abstract: Considering the deflection can represent the distortion of the subgrade and pavement layers all together, the deflection index is adopted for full depth pavement structure analysis. In China, the deflection formula is ...

Abstract: First, the axle-load skid-resistance conversion formula of asphalt pavement was established in accordance with the equivalent principle of skid-resistance performance attenuation which is similar to the way of axle-load ...

Abstract: Laboratory rutting tests for AC20 under the condition of different temperatures (30°C, 45°C and 60°C), wheel pressures and wheel running speeds were carried out with an improved wheel rutting tester whose wheel running ...

Abstract: This research explored the variation in the bond-breaking effect with a variety of bond-breaking layers installed between concrete pavement surface slabs and lean concrete base to determine the parameters for the structural ...
