York Materials Group is a leading asphalt manufacturer in South Central Pennsylvania, with a well-earned reputation for providing our customers with personal service and quality materials. Our plants are PennDOT-certified; each plant has a PennDOT-certified technician providing on-site testing daily. Additionally, all our plant locations feature batch-loading, and delivery service is available upon request. With four centrally-located plants and an extensive trucking fleet, York Materials Group has the flexibility to efficiently accommodate your project demands. Our in-house labs perform testing on our materials as needed for certain special applications and to check gradations, specific gravities, etc. Weekend/nighttime hours are available upon request (start-up costs may apply).


We produce a variety of mixes, including SuperPave, Marshall Mixes, porous pavements, and warm mix asphalts. In most of these mixes, we utilize reclaimed asphalt pavement (RAP) or reclaimed asphalt shingles (RAS) as part of our recycling program.
