About St. Thomas Development

The St. Thomas Development Company, located on Old Lincoln Highway (Rte. 30) just west of I-81 and Chambersburg, Pennsylvania. All HMI asphalt plants including St. Thomas are fully automated with a test lab for Quality Control and PennDOT approval.

Besides being a PennDOT approved hot mix asphalt producer, we can also provide porous asphalt for pervious pavement applications including parking lots and driveways for effective storm water management.

Recycling - Clean asphalt, including unused hot mix, breakup and millings will be accepted at St. Thomas at no charge. We have limited space available and loads are subject to inspection.
