沥青老化临界状态与极限状态的确定
Defination of the Critical State and Limit State of Asphalt Aging
摘要
Abstract
Through the Panjin asphalt (AH -90) aging test by different aging time in Lab, the performance data of the aging asphalt and mix of different time have been tested, the varied range of the main test data of the penetration (25 ℃) is 13 - 78 (0. 1 mm) , the relationship between the aging index and the aging time has been established, and the grades of asphalt aging based on the aging index and the ratio of remaining penetration has been put forward, the aging asphalt has been classified as 5 grades, based on the asphalt aging grades, the critical state and limit state of the aging asphalt has been defined .关键词
