Study on the Pavement Performance of Rubber Asphalt Inverted Seal

Inverted seal belongs to a new seal layer structure, which can be used for old cement concrete pavement modification work. In order to assess the superiority of inverted seal based on pavement performance, the authors attempt a comparative analysis of inverted seal and single chip seal through a laboratory test. The results show that laying a 2cm thick rubber asphalt inverted seal between the old cement concrete pavement and asphalt layer will increase the bonding properties by 30% and the fatigue life by 20% as compared to a single chip seal.
