Letter to the editor: Late-season paving may be the catalyst for road issues

Gary Strome

In response to a letter about the road surface quality in Frisco, the asphalt pavement is blowing up from frost expansion in the asphalt.

I recommend the county reduce air void, increase asphalt content and seal the surface from water intrusion. A fog seal can assist. Polymer-modified asphalt binders can assist pavement longevity, as well.

Late-season paving at lower temperatures may be the catalyst. Cooler weather forces the asphalt to harden prematurely while overworking the mix may fracture the internal bonds.



Frequently, the mix is hauled long distances. Not in my backyard is often the culprit.
