Hot, Cold or Warm Mix Asphalt

Reliable can produce all of today’s high-performance asphalt paving products, or can tailor a mix or installation to suit your project’s specific needs. Our quality control lab and certified technicians ensure consistency.

Reliable also produces and stocks a variety of aggregate materials, from sand to stone and offers delivery and installation of these materials as well.

Need it paved? In conjunction with asphalt production, Reliable’s professional crews can pave it for you. Our crews can be seen milling and repaving countless state highways, county roads, airport runways, government properties, commercial parking lots and community streets. By controlling the raw paving materials, asphalt production, trucking, and installation, Reliable can provide complete single-source solutions for your Maryland asphalt paving project.

Green Industry Commitment

Asphalt 1Reliable has always been an innovator in the use of recycled materials whether it is through burning recycled oil for fuel, producing asphalt paving mixes or recycling asphalt and concrete for base materials. In addition, we produce and install warm-mix asphalt, a product that reduces our energy usage and increases the workability of the mix while still meeting rigorous industry criteria for installation and durability. Fulfilling the production requirements of our customers while getting the most beneficial use from our finite resources is fundamental to Reliable’s environmental commitment.
