Title: Study of the Aging Characters of TLA Modified Asphalt Mortar
Abstract: In order to study the aging characters of TLA modified asphalt mortar,this paper uses the Rolling Thin Film Oven Tests to simulate aging mortar,the high temperature and low temperature performances of asphalt mortar at different amounts and mass ratios of mineral powder were and studied,also the asphalt mortar not aging was studied to compare.It is found that the TLA asphalt has a great impact on the asphalt mortar characters,but the impact is more notable when the the mortar aged.Through the studies,when the amounts of TAL is less than 20%,the changes of amounts have great influence on the performances of asphalt mortar,while when the amounts of TAL above 20%,the influence would be less.The mass ratio of mineral powder has the same regular,when the demarcated is 0.8,the changes of amounts have great influence on the performances of asphalt mortar,while when the demarcated above 20%,the influence would be less.The research also found that the aging could enhance the high temperature performances of asphalt,but weaken its low temperature performances.
