基于室内试验的橡胶沥青老化性能研究
Study on Aging Performance of Rubber Asphalt Based on Laboratory Test
摘要
Abstract
In view of the phenomenons of that Gansu province has complex topography and strong ultraviolet radiation,the asphalt pavement in the service period often appears aging and other diseases the rubber asphalt aging performance was studied in laboralory.The original rubber asphalt is carried out short-term and long-term aging simulation test by the Asphalt rotary film heating test (RTFOT) and the pressure ageing vessel (PAV).The RTFOT aged sample was placed in ultraviolet radiation box for ultraviolet aging,and then carried out the Dynamic Shear Test (called DSR).The results showed that:the rubber asphalt used in the test has better ability to resist fatigue and anti-ultraviolet ageing,which is suitable for the high altitude and strong ultraviolet region in our country.关键词
