CalPortland Portable Asphalt Rubber Blending Plant

The contract authorizes the temporary deployment of a portable skid-mounted asphalt rubber blending plant at the CalPortland Garey Asphalt facility in Santa Maria, California, for recurring annual use. Rubber, delivered in sacks via trucks, is unloaded into a weigh hopper and transferred via a covered conveyor to a mixer where it is combined with paving asphalt sourced from an on-site storage tank. The mixture is heated to 375 degrees Fahrenheit to create an asphalt-rubber blend, which is then stored in a 30,000-gallon tank before being transported to CalPortland’s main asphalt and concrete mixing plant. Two propane-fired burners, rated at 1.999 and 2.700 MMBtu/hr respectively, provide heating for both the primary and secondary 30,000-gallon storage tanks to maintain material viscosity. The entire operation is powered by grid electricity, ensuring consistent and reliable energy supply without on-site generation. The project is managed under the oversight of the Santa Barbara County Air Pollution Control District, with Carly Barham serving as the primary point of contact for air quality compliance and operational coordination. Cliff Ashcroft, the owner of the blending plant, is listed as a secondary contact. The solicitation is posted as a forecast with no formal solicitation number, indicating it is a forward-looking notice to prepare industry participants for potential future award opportunities. The plant will remain temporarily located at the CalPortland site on an annual basis, subject to regulatory and operational approvals, with all activities centered around producing modified asphalt binder for use in roadway construction within the region.
