Anti-fatigue Property of Foamed Warm-mix Recycled Asphalt
Journal Title: 河南科技大学学报（自然科学版） - Year 2017, Vol 38, Issue 2
Abstract
In order to explore the effect of recycled asphalt content on the anti-fatigue property of foamed warm mix recycled asphalt,by three index test,dynamic shear rheological test and scanning electron microscope test the changes in anti-fatigue properties of foamed warm-mix recycled asphalt were evaluated. The results show that with the increase of recycled asphalt content,the fatigue factor and the ultimate fatigue temperature value of the foamed warm-mix asphalt increase gradually. While the fatigue life is reduced,and the anti-fatigue property of the foamed warm-mix asphalt is getting worse. When recycled asphalt content is more than 60%( mass fraction),the anti fatigue ability of the foamed warm-mix recycled asphalt is worse significantly. The smooth surface of the foamed warm-mix asphalt is gradually changed into clear folds,and the rigidity is stronger.
