Asphalt pavements often experience premature distresses caused by extreme environmental condition of both high and low temperatures. By maintaining a stable temperature a potentially longer lasting pavement is achievable. Laboratory tests and a field study were conducted on Hot Mix Asphalt pavements using a Geosynthetic Reinforced Chip Seal (GRCS); the temperature data from the two tests were compared for the GRCS’s effectiveness in reducing the pavement high temperatures. It was found that using a GRCS with an asphalt saturated geosynthetic layer and a chip seal with high reflectivity aggregates is an effective way to reduce high temperatures at different depths in the pavements. Field studies showed a temperature reduction of 9.2OC at the original surface and 10.3OC at 12.5 mm below the original surface, for an air temperature of 49OC.
