Asphalt Pavement Thickness and Mix Design - Asphalt Institute

Jun 28, 2021  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.
