CORRECTING and REPLACING GARCO Testing Laboratory Joins California Green Business Network

CORRECTION...by Granite

WATSONVILLE, Calif.--(BUSINESS WIRE)--Second paragraph, first sentence of release should read: GARCO Testing Laboratories offers material design and quality testing services. (instead of GARCO Testing Laboratories, a wholly owned subsidiary of Granite Construction Company, offers material design and quality testing services.).

The updated release reads: 

GARCO TESTING LABORATORY JOINS CALIFORNIA GREEN BUSINESS NETWORK

Granite (NYSE:GVA) announced today that GARCO’s San Jose Testing Laboratory recently joined the California Green Business Network. The testing facility functions as the base of operations for materials testing across Granite’s Coastal California Region. As part of the Green Business certification, the facility satisfied targets for energy efficiency, water conservation, procurement, and materials management.

GARCO Testing Laboratories offers material design and quality testing services. The GARCO team works with a simple goal: maximize opportunities to provide superior products with exceptional service, while keeping people safe and being good stewards of the environment.

The GARCO team has extensive asphalt paving expertise, including use of specialized designs to satisfy specific, unique project requirements. GARCO personnel pursue industry certifications like the Caltrans Joint Training & Certification Program (JTCP), which include individual areas of specialization, require in-person classes and laboratory training, and written/practical examination sessions.

The GARCO team prioritizes responsible material management and proper disposal of all waste streams, even in the laboratory. For example, the asphalt and aggregate samples they collect for testing are delivered back to a material production facility or asphalt plant, meaning a single laboratory can divert 9-10 tons of waste from landfills each year.

Asphalt mix designs drive sustainable material use in commercial construction. Mix standards set targets for the percentage of recycled asphalt pavement (RAP) in a mix. Material specifications are changing across the industry to allow for higher RAP contents. GARCO recently obtained approval for 30% RAP-content mix design and hopes to achieve even higher thresholds in future mixes. The company is also exploring the use of recycled plastics to displace liquid asphalt binder, which has the potential to reduce use of petroleum products and find new beneficial uses for certain types of plastic.

GARCO and Granite take pride in advancing the best available technologies and practices across the construction materials industry. Look for more information about Granite materials in our upcoming Sustainability Report.
