Foamed bitumen and cement were respectively used as a stabilizer for foamed asphalt cold recycled roads to study the secondary cold recycling technology.The laboratory research results show that for the secondary cold recycled mixes with foamed bitumen as a stabilizer,their tensile properties and water-stable performance was related to the fines content in the mixes;the high temperature stability of secondary cold recycling mixes is related to the RAP(recycling asphalt pavement) content,the aging degree of asphalt and the fines content.Cement was adopted as a stabilizer in the second regeneration mix design,and the 7 d unconfined compressive strength was made in use to well determine the proportion of newly added aggregate.An appropriate new aggregate can significantly increase the 7 d unconfined compressive strength of mixes.Through the laboratory study and tested road application,the foundation of future development of the secondary cold recycling technology was laid.
