Problem Statement

The geosynthetic material GlasPave™ has been effectively used at the bottom of asphalt surface layers to help mitigate the potential for thermal and stress-related cracks. However, there is concern regarding whether or not pavements containing GlasPave can be recycled. Specifically, will reclaimed asphalt pavement (RAP) material containing milled-up GlasPave affect the performance properties of asphalt mixtures containing the RAP?

Objective

This study by the National Center for Asphalt Technology (NCAT) was conducted to evaluate the effect of GlasPave in RAP by comparing the performance properties of two asphalt mixtures: one containing control RAP and the other containing GlasPave RAP materials.
