Abstract
The problem of reflective cracks in asphalt pavements with semi-rigid bases has not yet been effectively solved. This paper proposes a new construction method called continuous construction of the base and asphalt layers (CCBA). In this method, an anti-cracking agent is added to the cement-stabilized base material, and the asphalt pavement is applied when the base has been compacted but not initially set. Laboratory tests of the anti-cracking agent were performed, and test roads in the field were evaluated. The test roads showed that compared with the conventional construction technique (CCT), CCBA results in fewer cracks, can protect the base from cracking, and strengthens the bond between the base and the asphalt pavement.
