Resistance to Disintegration of the Rubberized Porous Asphalt

抄録

Porous asphalt mainly rely on the binder content and binder properties for cohesion between aggregate particles where good cohesion would increase resistance to permanent deformation like raveling and stripping. This paper presented the results of Cantabro Abrasion Loss Test on rubberized porous asphalt. Specimen was prepared by different percentages of binder content, rubber content and mixing process namely wet process and dry process. Two condition of samples i.e air cured sample and water soaked sample were used to simulate raveling and stripping respectively. Results indicated that incorporation of low amount of rubber exhibited better abrasion resistance in wet mixing process. Whereas, resistance to abrasion increases as rubber content increase on samples prepared by dry mixing process. The study showed that dry process samples were more effective compared to wet mix in reducing abrasion loss for both conditions of sample.
