What Customers Say
PW Manager Jerry Long On How RockAsphalt© Cut Road Complaints In His City By 55%
“A few bags of RockAsphalt turned any truck we had into a “pothole repair vehicle” and that’s what got us through the winter. […] I was skeptical they [the patches] would hold up but most all of them did, even the ones in high-traffic intersections. They [RockAsphalt] changed the way we work. I'd recommend the product to anyone.”Jerry LongPW Manager, HCC
