Effect of temperatures and loading rates on direct shear strength of asphaltic concrete using layer-parallel direct shear test

Effect of temperatures and loading rates on direct shear strength of asphaltic concrete using layer-parallel direct shear test

This paper evaluates the influence of temperatures and loading rates on the shear strength of dense asphalt (AC14) prepared based on the Malaysian Public Works Department specification. In this study, different specimen conditioning temperatures, 10°C, 20°C, 30°C, and loading rates of 20.88mm/min, 4...

As the temperature increases, the stiffness of the asphalt mixture reduces due to the lower resilient modulus; therefore, it reduces the shear strength of the specimen.
