  • Why Tracking Temperatures is Key to Successful Asphalt Paving

    Air temperature is a factor in cooling hot mix asphalt pavement, but the base or ground temperature is more critical. The second step is base or ground temperature. Monitoring the base (ground or existing pavement) temperatures can be accomplished with an infrared thermometer (purchased at an instrument outlet, Sears, Home Depot, etc.) to
