Mission Statement
CalCIMA’s Hot Mix Asphalt (HMA) producer members work to support, advocate, and advance the asphalt pavement industry.  Our members are comprised of companies ranging from small driveway – paving operations to diverse larger construction companies that produce and/or place asphalt pavement on roads, airports, parking lots, recreational facilities, etc.
Our members include Asphalt Producers and Associate Members that all work together to supply materials, equipment, and support for the HMA industry.  As part of our mission, we provide technical assistance and training related to the production, construction, and testing of HMA. 
CalCIMA’s office is strategically located in Sacramento, California which enables it to work closely with the California Department of Transportation (Caltrans), the Federal Highway Administration (FHWA) and other industry associations.
About Hot Mix Asphalt (HMA)
Asphalt is the primary form of highway pavement in California covering an estimated 93% of California’s paved roadways.  Nationally, approximately 95% of US highways are comprised of HMA.  Asphalt is a proven performer that can be customized to any paving application.
HMA is made from crushed rock, sand, and asphalt binder. Other ingredients might include Reclaimed Asphalt Pavement (RAP), Recycled Asphalt Shingles (RAS), recycled plastic and ground tire rubber.  The ingredients in HMA are combined and mixed in batch plants or continuous mix drum plants prior to being transported to the project site for placement.

Asphalt pavements have a low life cycle cost, are 100 percent recyclable and the most recycled product in the United States.  More asphalt is recycled each year than aluminum, paper, glass and plastic combined. The use of reclaimed asphalt pavement (RAP) serves to reduce the cost of our roads and highways while at the same time reducing greenhouse gas (GHG) emissions and diverting solid waste from landfills.
