Public Works Testing New Roadway Patch

Published on May 13, 2025

The Public Works Department is testing RockAsphalt, a natural asphalt patching product, to improve roadway maintenance and reduce costs.

Made from bituminous limestone mined in Texas, RockAsphalt requires no heating and remains usable indefinitely, unlike traditional patches. It also comes with a three-year guarantee -- if a patch fails, the company provides a free replacement, and the warranty restarts.

Applying RockAsphalt is simple: crews clean the pothole, press the material into place, and compact it with a vehicle or machinery. The patch is traffic-ready immediately and bonds over time. Each 50-pound bag covers 7 square feet at a 1-inch depth, providing more coverage than many current materials. Its easy storage allows Public Works vehicles to carry it for quick, on-the-spot repairs.

"This product could be a valuable tool to help our teams respond more efficiently to roadway damage," said Ali Ismailoski, Right of Way Division Manager. "It’s costeffective, environmentally friendly, and helps us better serve the community."

RockAsphalt is widely used in Florida and Georgia, and Clearwater is now evaluating its performance for potential long-term use.

"RockAsphalt has been around for over a century, and its durability and ease of use makes it an excellent choice for municipalities looking for longlasting, cost-effective repairs," said Randy McGaha, Government Territory Manager for RockAsphalt. "Its long shelf life, and ability to be used in extreme temperatures, gives road crews greater flexibility when responding to repairs."

The Public Works Department will continue to assess RockAsphalt as part of its commitment to improving road maintenance and service across Clearwater.
