FIVE-YEAR EXPERIENCE OF LOW-TEMPERATURE PERFORMANCE OF RECYCLED HOT MIX

摘要: The thermal cracking results of five recycled hot-mix (RHM) sites constructed between 1981 and 1983 during the early recycling program Ontario Ministry Transportation are presented. from laboratory field evaluation, involving comparison two types use McLeod's limiting stiffness criteria fracture temperature method. study confirms common belief that RHM is less resistant to than non-recycled mixes. Fracture method was found be better approach for evaluation low cracking. Recommendations improve performance also made.
