Abstract: The objectives of this paper are twofold: (1) Investigate the low-temperature reversible aging discrepancy mechanism of the asphalt binders with similar regular low-temperature performance grade; and (2) evaluate ...

Abstract: Crystalline wax in asphalt binder greatly affects the low-temperature performance of the asphalt pavement, and the composition of the phase separation at the microscopic scale has not been completely determined. In this ...

Abstract: Recycled engine oil bottoms (REOBs) are widely used in asphalt binders for modification and cost saving. However, more early road failures have appeared on the pavements constructed with REOB-modified asphalt binders in ...

Abstract: Racking in asphalt pavements has always been the leading cause of pavement damage. This study aims at investigating the effects of mesostructure characteristics of asphalt mixture on the fracture behavior of semicircular ...
