MatCon Modified Asphalt

The MatCon® (Modified Asphalt Technology for Waste Containment) system is an advanced modified asphalt technology that combines Granite Construction’s proprietary binder with tightly specified aggregates. MatCon Hot Mix Asphalt (HMA) offers unique advantages for environmental capping and containment. Unlike conventional asphalt concrete, MatCon permeability (<1 x 10-7 cm/sec) is lower than that required under RCRA, while also offering resilience and longevity.

These qualities make MatCon a superior containment alternative for environmental applications, particularly when site reuse is an objective. When MatCon is installed as a nominal 4-inch thick cap, a site that once had no value will have a variety of potential alternative uses such as: parking, equipment storage, truck/train intermodal facilities, multi-use sports facilities. In these and other ways, a liability on a balance sheet can be transferred to the asset ledger.
