Evaluating Thermal Characteristics of Foam Glass Aggregates as an Insulation Layer in Asphalt Pavements

Abstract

AbstractCold region pavements experience extreme weather conditions that lead to structural issues like soil freeze-thaw cycles and upheaval. Insulation materials such as extruded polystyrene boards (XPS), foam glass aggregate (FGA), and tire chips (TC) ...Practical ApplicationsComplementary strategies were explored to enhance insulated pavement performance during the material selection and design stages. Partial replacement of foamed glass aggregates (FGA) with tire chips could improve its compaction, ...
