Analysis of Viscoelastic Mechanical Model of Recycled Asphalt Mixture Based on Bending Creep Test

Abstract

The recycle of asphalt pavement material is not only accordance with the policy of national energy conservation and emission reduction, but also can significantly reduce the project cost. Viscoelastic mechanical model of recycled asphalt mixture is studied based on pavement maintenance engineering of Shenyang-Shanhaiguan expressway, and with analysis of material performance we could collect testing data from bending creep test on small beam, obtain testing parameters through fitting method. The results indicate that general Maxwell model could nicely reflect the viscoelastic mechanical behavior of recycled asphalt mixture.
