Mix temperature is dependent on the grade of asphalt used in the mix. Less viscous the asphalt requires lower the temperatures, while more viscous asphalt requires higher temperatures.At the start of a mix design project, target temperatures are specified for proper mixing and compaction.
The thermal conductivity of asphalt concrete is affected by its volumetric parameters and thermal properties of each component. If an analytical model is available to predict the effective thermal conductivity of asphalt concrete based on its microstructure, experiment costs can be significantly saved.

The mix design is used to establish the proper proportioning of components (hydraulic cement, aggregates, water, pozzolans, and admixtures) in the mixture to achieve the specified properties. Significant concrete properties are strength, air content, slump, and the coefficient of thermal expansion (COTE).
