  • Why Tracking Temperatures is Key to Successful Asphalt

    HMA Temperature. The final step is checking the temperature of the hot mix asphalt prior to installing it on the base. This should be accomplished by taking the temperature of the pavement in the haul truck, at the front of the laydown machine and behind the screed (after the laydown machine has passed).

  • Asphalt concrete - Wikipedia

    High temperatures soften the asphalt binder, allowing heavy tire loads to deform the pavement into ruts. Paradoxically, high heat and strong sunlight also cause the asphalt to oxidize, becoming stiffer and less resilient, leading to crack formation. Cold temperatures can cause cracks as the asphalt contracts.
