Abstract
In traditional restoration and reconstruction of transportation, the long-term closed traffic and generation of solid waste in the road maintenance section exert a negative influence on the local society, economy, and environment. This study aims to determine the suitability of using the Early strength Anti-cracking Material (EAM) to achieve the reutilization of Milling-planing Materials (MM) reclaimed from broken Cement-Stabilized Macadam (CSM) bases and to reduce the maintenance time effectively. Thus, some tests of MM were conducted to evaluate its engineering properties. The mechanical, shrinkage, and fatigue tests were carried out to determine the effects of cement dosage, MM and EAM. Results indicate that with the use of small quantities of cement, fine mechanical properties still exist in the structure after the total substitution of MM for Natural Aggregates (NA). The incorporation of EAM has little influence on long-term mechanical strength. Instead, it introduces the possibility of getting rid of vehicle-passing restrictions five days in advance of road maintenance. Additionally, it was confirmed that the cement-stabilized MM with EAM has acceptable shrinkage resistance and fatigue properties. These results demonstrated the possibility of using EAM to produce more rapid-recovering and sustainable pavements.
