Abstract

Highlights: Putting forward the primary factors effecting the performance of FACRM pavement. Describing FACRM's engineering properties and suggesting a suitable layer structure. Suggest optimum pavement structure combinations for different traffic conditions. Abstract: The properties of foamed asphalt cold recycling mixture (FACRM) will seriously affect the application performances of pavement structure made from FACRM. The results from this study suggest that FACRM has a high modulus and small temperature shrinkage stress, reducing early damage caused by pavement cracks. FACRM has good water stability but poor stability at high temperatures. The strength of the old subgrade, thickness of the FACRM and environmental temperature have significant effects on the performance of pavement structure. FACRM is ideally used as pavement material for light traffic, but not suitable for use as a surface layer for heavy traffic.
