Production of HMAC is a multifaceted operation blending in correct proportions aggregates, liquid asphalt binder and mineral fillers to achieve a product second to none. All mix designs at Terra Firma Materials are Txdot approved, meeting stringent requirements as set forth by DOT. Our onsite quality control department ensures a consistent asphaltic mix by continuously testing as produced. Warm Mix Asphalt (WMA) is produced similar to HMAC, however at a reduced temperature 25-50 degrees less. At Terra Firma Materials we incorporate the use of a Green System which encapsulates micro beads of water into the asphalt binder causing it to foam and expand. WMA has shown great benefits to both producer and consumer as a reduction in cost for both.
