Application of Central Plant Hot Recycled Asphalt Mixture in Pavement Construction

Abstract

The hot recycling technology (HRT) can recycle old pavement materials, reduce the total social cost of the project, use of limited asphalt and stone resources to build more highways[1]. HRT can protect the environment and have significant economic, social and environmental benefits. Marshall test and screening test are conducted for each batch of mixed sample and the physical and mechanical properties of oilstone ratio, mineral grade and asphalt mixture are tested. The transportation, spreading and rolling of recycled asphalt mixture is according to the Technical Specification for Highway Asphalt Pavement Construction (JTG F40-2004). The results of immersion Marshall test and rut test shows that the performance indexes meet the design requirements.
