Many asphalt paving jobs start with a long process. The asphalt is mixed, heated, and then transported to the worksite, where it is most often stored in tanks until needed. When asphalt arrives on site, it is often at its warmest temperature of about 190 degrees Fahrenheit. This asphalt needs to be spread out into the desired thickness before being rolled or dragged into position for installation. Learn information about Lower Paxton Township, PA.

To keep it looking good and performing well, we sealcoat asphalt pavement.
