Abstract

Recycling asphalt concrete pavements investigated by means of utilizing the asphalt and aggregates they contain, and solving waste disposal problems. Discarded asphalt concrete pavement materials of crushed asphalt from existing pavement studied. Laboratory testing
showed that this material could be recycled successfully into quality pavement materials. This successful recycling accomplish by mixing the crushed asphalt with cement. Four different of cement content were utilized to obtain a reasonable mixing for pavement materials. Further, those four mixing of cement and crushed asphalt tested at the three different temperatures 10°C,30°C, and 50°C to be able toapply in the tropical country like Indonesia. To get workable mixture, a water-cement ratio 1 has chosen. Specimen with cement content of 3.75% by mass of crushed asphalt has reasonable properties to use as a road base of pavement and comparable to the other specimens who have cement content 6.25%, 7.50%, and 8.75%. Pavement recycled materials with cement were also found still have linear elastic behaviour which enable to be analyzed as a flexible pavement. Mechanistic design procedure used to analyze the pavement life and the future performance of the pavement analyzed by using TRRL design procedure. Successful analysis has demonstrated that cement-stabilized crushed asphalt is reasonable to use as a road base of the pavement and can applied in tropical country like Indonesia.
