New Wheel Tracking Test to Analyze Movements of Aggregates in Multi-layered Asphalt Specimens
Asphaltic mixture Permanent deformation Strain distribution
2009/7/27
This paper describes a new wheel tracking test for analyzing movements of aggregates in mixtures. The test device is conducted using as examples four-layered specimens taken from two Swiss national m...
Separation and Recovery of Aggregate from Asphalt Pavement Wastes Using High-temperature and High-pressure Water
Supercritical water Pavement waste Aggregate Binder Straight asphalt
2009/7/27
The recycling ratio of reclaimed asphalt pavement (RAP) reached about 99% in 2002, the highest for any industrial waste, a clear sign that recycling efforts are actively applied in the road pavement f...
Crack Formation in Asphalt Mixtures in the Wheel Tracking Test at High Temperature
Dense graded asphalt Drainage asphalt Internal cracking Stress distribution
2009/7/24
The formation of internal cracks in asphalt mixtures in the wheel tracking test at high temperature was investigated in dense graded (13F) and drainage asphalt mixtures prepared outside. Such cracks ...
Mechanism of Asphalt Binder Aging by Ultraviolet Irradiation and Aging Resistance by Adding Carbon Black
Asphalt binder Ultraviolet irradiation Aging Carbon black Carbonyl group
2009/7/24
The components of asphalt binders were separately irradiated with ultraviolet (UV) rays to examine the aging mechanism. The results confirmed that saturates are converted to resins and asphaltenes, r...
Movement Characteristics of Aggregates in Asphalt Mixtures during the Wheel Tracking Test
Asphalt mixture Deformation characteristic Wheel tracking test
2009/7/24
The deformation characteristics of asphalt mixtures in the crossing direction during the wheel tracking test (1 h, 2500 passes) at high temperature were investigated using dense graded (13F) and drai...
