Study on Pavement Performance of Plant-mix Hot Reclaiming Asphalt Mixture (PHRAM)

摘要

In this study, plant-mix hot reclaiming asphalt mixture can be used to surface and sub surface taking DAC-13I and DAC-20I asphalt mixture with five different RAP contents as 0%, 10%, 20%, 30%, 40%. The fatigue, rutting, water damage and cracking tests in laboratory have been taken to evaluate the road performance, and flexure, rutting, asphalt content tests have been taken on the trial sections to evaluate the practice road performance. The result of tests shows that plant-mix hot reclaiming asphalt mixture should be good service performance as new asphalt mixture when the RAP content is appropriate.
