摘要: In this paper, the aging processes of colored paving asphalt conforming to GB/15180-94 standard were studied by rotate thin film oven (RTFO) test. The results show that established two dynamics models can be use describe velocity kinds perfectly. After aging, asphaltene content increased, resins and aromatics content, as well saturate decreased. As a result, original colloidal structure is destroyed, which deteriorates performance asphalt. During Gastel index (Ic), sensitive conditions, decreased with increase temperature extension time. Therefore, used evaluate resistance
