U416 110814030603 Study on Performance Evaluation and Improvement of SEAM Asphalt Mixture (Supported by the department of Science and education of ministry of transport, No.) 2008 11 2008 12 2009 3 2008 12
Abstract Correlation experimental investigations on the road performance of SEAM asphalt mixture has been carried out by using Marshall TestWheel Tracking TestImmersion Marshall TestTSR TestTSRST Test Fatigue Test and so on, and has a systematic comparison of the performance of asphalt mixture and SBS modified asphalt mixture. The improving measures of the low temperature cracking resistance and the moisture stability performance of SEAM asphalt mixture is put forward by investigation on performance of SEAM aspahalt mixture.analysing the feasibility of low angularity mineral aggregate and high- wax asphalt into the pavement by evaluation on SEAM high-wax contented asphalt mixture and SEAM low angularity mineral aggregate asphalt mixture road performance. The findings of the research are as followings: 1)SEAM can prominently improve the high-temperature stability of asphalt mixture. 2)TSRST is an effective research on the low temperature cracking resistance performance of SEAM asphalt mixture.explicit fracture temperature is suggested as the director of evaluating the low temperature cracking resistance performance of SEAM asphalt mixture. The research shows that SEAM can not decrease the low temperature cracking resistance performance of asphalt mixture.increasing the doze of SEAM asphalt mixture can effectively improve the low temperature cracking resistance performance. 3)The moisture stability performance of the asphalt mixture mixed SEAM is degraded to some extent.the study shows that through increasing the doze of asphalt, adding antistripping agent and improving the mixture mold temprature can improve the moisture stability of the SEAM asphalt mixture effectively. 4)SEAM is enable to improve the road performance with low angularity mineral aggregate and high- wax asphalt, and to enlarge the applied range of these low quality materials. 5)The fatigue Test which stress control methods shows that the anti-fatigue performance of SEAM asphalt mixture is close to asphalt mixture. The evaluation and improvement of the performance of SEAM asphalt mixture is demonstrated in this paper, so that perfected SEAM asphalt mixture technique and offerred reference of the future practical application of the SEAM asphalt mixture. keywords: SEAM asphalt mixture; Road performance; Evaluation method; TSRST;Fatigue test; Performance improvement measures
