The conventional French fatigue test has yielded significantly different results for two asphalt materials with the same grade of pure asphalt. A research program was begun to study the influence of the asphalt nature on the fatigue behavior of asphalt materials. The program included full-scale experimentation on the circular test track of the Laboratoire Central des Ponts et Chaussees, laborat...
The effectiveness of weight ratio mineral filler to effective bitumen in the fatigue performance asphalt mixture with integral granules was investigated based on experiments mastic (mixture and passed through sieve grade 200). included a dynamic shear rheometer, elastic recovery, linear amplitude sweep tests other mixture, such as indirect tensile resilient modulus test for assessing medium tem...
In pavement structures that are often submerged by water, the damage to is caused loss of bonds or adhesions between aggregate and asphalt, type occurs due adhesion asphalt exfoliation granules so road cracked corrugated. To reduce release improve bond aggregates can be made with addition anti-exfoliating additives antistripping agent additives. This study aims analyze performance wear-coated c...
γ-(2,3-Epoxypropoxy)propyltrimethoxy silane surface modified layered double hydroxides (KH560-LDHs) were prepared and used to improve the ultraviolet ageing resistance of asphalt. The results of X-ray photoelectron spectrometry (XPS) indicated that KH560 has been successfully grafted onto the surface of LDHs. The agglomeration of LDHs particles notably reduced after KH560 surface modification a...
Dynamic modulus is a key evaluation index of the high-modulus asphalt mixture, but it relatively difficult to test and collect its data. The purpose achieve accurate prediction dynamic mixture further optimize design process mixture. Five high-temperature performance indexes were selected. correlation between above five was analyzed. On this basis, models based on small sample data established ...
