High temperature concrete pavement pdf
Webexposure to high temperatures such as during fire, the mechanical properties of the concrete such as strength, elastic modulus and volumetric stability are significantly … Webat low strain amplitudes. At low temperatures, the asphalt concrete behavior is a combination of elastic and slight linear viscoelastic. Temperature is a significant factor and it is not considered in the existing design guide (AASHTO design guide, 1993). It influences the performance of pavement, especially asphalt concrete (AC).
