Abstract

Because the Asphalt concrete pavement heavy-duty rutting, low temperature cracking and anti-fatigue cracking problems are prominent, the author mix the BRA rock asphalt and polyester fiber into the asphalt mixture preparation of wide temperature field asphalt mixture in accordance with various proportions. By making use of the comprehensive modification function of asphalt mixture, this thesis evaluates the road performance of the composite modified asphalt mixture. Test results: BRA and polyester fiber compound can greatly improve the integrated road performance of BRA rock asphalt and polyester fiber modified asphalt mixture. After the mixture of BRA and polyester modifier with dry process, the composite asphalt mixture have both high and low temperature performance, and the high temperature performance increased by 45%, low temperature performance increase by 82% comparing with SBS modified asphalt mixture. The anti - fatigue performance under the compound modification scheme is better than that of SBS modified asphalt mixture. Engineering practice shows that the combination of asphalt and polyester fiber asphalt mixture can improve the comprehensive road performance of asphalt pavement, and it can replace SBS modified asphalt.
