If it is a new construction project or maintenance on an existing site, DeSilva Gates Aggregates can provide asphalt concrete products to meet your needs. Our products include hot, warm and cold mix asphalt, as well as rubberized asphalt concrete and asphalt emulsion. We produce asphalt concrete products at our facilities in Sunol, Oakland and Marysville, CA.
DeSilva Gates Aggregates promotes the use of reclaimed asphalt pavement (RAP) and warm-mix asphalt (WMA) technologies, these two production methods conserve raw materials and energy, cut emissions from operations and improve environmental conditions for workers. Using RAP is more cost-efficient, and is often equal or greater in quality than traditional methods.
DeSilva Gates Aggregates is committed to producing the highest quality aggregate and asphalt materials available in the San Francisco Bay Area and surrounding region. All of our facilities have onsite certified laboratories with qualified technicians to ensure that the materials we are producing meet all of the required specifications.
In order to provide the Bay Area with quality asphalt both today and for many years into the future, DeSilva Gates Aggregates recently installed and began operating a new Astec Double Barrel drum asphalt mixer at its Sunol facility. Not only is this plant one of the highest production plants on the West Coast producing over 500 TPH it is also the most environmentally friendly plant currently operating in the United States.
