Dosage Study

Rutting in asphalt pavements continues to create problems for pavement. The aim of this study was to analyze the influence of different gradation composition, asphalt dosage, temperature and dosage of anti-rutting agent on high-temperature stability of cosely gap-graded bituminous mixture. To achieve this objective, 171 different rutting specimens using different mix parameters were analyzed for their the high-temperature stability. The mix parameters include: three types of aggregate gradation, five types of asphalt dosage, four types of temperature and five types of anti-rutting agent dosage. Study results indicate that adding proper content of coarse aggregate can play occluding and wedging role in aggregate mixture. The optimal bituminous dosage in rutting test are lower 0.1%~0.3% than that in Marshell test. At 65°C, the high-temperature stability of the cosely gap-graded bituminous mixture is not able to meet the requirement of standards. The optimal dosage of anti-rutting agent are equal to 0.3% in case of no increasing bituminous dosage.
