Warren Asphalt (formerly Warren Materials) has been a trusted member of H&K Group, Inc.’s (H&K’s) construction materials team since 1999.  Located in Stewartsville, NJ, the Warren Asphalt facility location first began producing asphalt in 1952. Though steeped in tradition, our new state-of-the-art asphalt plant utilizes this key Warren County, NJ location to provide our civil construction and infrastructure customers with the high-quality asphalt products they have come to expect from Warren Materials. 
Conveniently located just off Route 78 on Route 57 in Warren County, NJ, we offer both NJ and PA approved asphalt and aggregate products to the surrounding region. We are also an approved recycling center for incoming recycled asphalt pavement, or RAP.
OUR ASPHALT:
Utilizing high quality raw aggregate and sand materials from H&K’s own facilities, Warren Asphalt produces a wide variety of asphalt mixes, including standard Marshall and SUPERPAVE designs that are New Jersey and Pennsylvania Departments of Transportation (NJDOT and PennDOT) certified. We also produce specialty and custom mix designs, and our exceptional staff, combined with our plant layout and silo capacity, all add up to provide the high level of service and quality our customers have come to expect.
