Effects of Temperature Segregation on the Volumetric and Mechanistic Properties of Asphalt Mixtures

The objective of this research is to determine the impact of temperature segregation on the quality of asphalt mixtures as defined by measurements of density and mechanistic properties of asphalt mixtures. Specific objectives of this study include: ascertain temperature segregation range during paving operations; measuring the density of roadway cores at uniform and non-uniform temperature zones; measuring mechanical properties (Loaded Wheel Tracking test, Simi Circular Bent test, and Indirect Tensile Dynamic Modulus test) of roadway cores at uniform and non-uniform temperature zones; and establishing an acceptable temperature segregation range during paving for specification purposes.
