Abstract

The utilization of foamed asphalt without lowering the production temperature of asphalt mixtures has become a new construction technique of foamed asphalt technology, but there is a lack of research on the influence of foamed asphalt on the performance of hot mix asphalt mixtures. By taking the on-site drilled core samples and indoor formed specimens as the research objects, this paper studied the influence of foamed asphalt on the high and low-temperature performance of hot mix asphalt mixtures via the dynamic creep test and SCB bending test. Finally, the construction effect of foamed hot mix asphalt mixtures was evaluated by paving the test sections. The results show that foamed asphalt can improve the high-temperature stability and low-temperature cracking resistance of traditional hot mix asphalt mixtures, and the asphalt mixture specimen formed by indoor Marshall cannot completely simulate the pavement situation of on-site asphalt mixtures. Under the same construction technique, foamed hot mix asphalt mixtures can achieve great compactness compared to ordinary ones.
