摘要：

The service life of porous asphalt pavements is limited due to raveling. Preventive maintenance to porous asphalt pavements by means of spraying rejuvenators on the pavement surfaces is considered as cost-effective. In the research of this paper, a loose asphalt mixture was artificially aged and then compacted. A rejuvenator was applied to the prepared porous asphalt concrete specimens. The stiffness modulus and indirect tensile strength of the specimens were measured using the indirect tensile tests. The results show that the application of the rejuvenator did not change the stiffness modulus and indirect tensile strength of the porous asphalt concrete specimens. (C) 2016 Elsevier Ltd.
