Thermal and fatigue cracking are pavement distresses that deteriorate asphalt pavements in Canada. However, the current AASHTO M320 standard specification protocol does not give satisfactory correlation between the properties measured in the laboratory to thermal and fatigue cracking performance of the asphalt in service. This work is aimed at validating the newly developed MTO LS-299 and LS-308 specification test methods for predicting pavement distress. The work has shown that the extended bending beam rheometer and double edge notched tension tests are better tools for predicting pavement…mehr

Produktbeschreibung
Thermal and fatigue cracking are pavement distresses that deteriorate asphalt pavements in Canada. However, the current AASHTO M320 standard specification protocol does not give satisfactory correlation between the properties measured in the laboratory to thermal and fatigue cracking performance of the asphalt in service. This work is aimed at validating the newly developed MTO LS-299 and LS-308 specification test methods for predicting pavement distress. The work has shown that the extended bending beam rheometer and double edge notched tension tests are better tools for predicting pavement performance and provide good specification tests for the control of thermal and fatigue cracking in modern pavements.
