An Experimental Study on Pavement Performance and Dynamic Mechanical Properties of Cold Recycled Mixtures Consisted of Modified Asphalt Emulsion-Cement Binders

Abstract:

The objective of this study is to evaluate pavement performance and dynamic mechanical properties of cold recycled mixtures consisted of modified asphalt emulsion-cement binder (CRMC). A cold recycled mixture design procedure that includes original material selection and gradation design has been applied. Then pavement performance of CRMC has been comparatively analyzed with the recycled mixtures without cement by theoretical and experimental methods. In addition, the tests for dynamic mechanical properties of CRMC have been conducted. The overall performance tests results indicate that CRMC has good strength, moisture stability, high temperature stability, low temperature stability, anti-shrinkage and fatigue resistance properties compared to the cold recycled mixtures without cement; Dynamic mechanical properties confirm that CRMC are similar to the hot mixtures asphalt (HMA), although a certain amount of cement is added.
