  • CalRecycle Awards $439,636 to Yuba County for Tire-Derived Aggregate Road Repair Project

     

    Back-hoe filling erosion with tire-derived aggregate.

    Yuba County is home to the latest construction project to use recycled waste tires to patch up damaged roadways. Last month, 430,000 tires were utilized as filling material to repair multiple roads destroyed by recent landslides.  

    CalRecycle awarded the county $439,636 as part of the Tire-Derived Aggregate Grant Program, which funded both the purchase of the recycled tire material and the repair work.  

    Tire-Derived Aggregate (TDA) is made from shredded scrap tires and is used in a wide range of construction projects. These uses include retaining wall backfill, lightweight embankment fill, landslide stabilization, vibration mitigation, and various landfill applications.

    The material is lightweight and cost-effective, and it drains well in wet conditions. 

    As an added bonus, recycling tires diverts them from landfills and illegal dumpsites. Currently, California generates more than 40 million waste tires per year. 

    Take a look at this video to see the recent Yuba County TDA project in action.

  • Santa Barbara County Uses CalRecycle Grant Funds to Rebuild Roadway with Recycled Tires

     

    Santa Barbara County builds retaining wall with recycled tires

    How do you repurpose 81,000 recycled tires? Well, use them to create a new retaining wall, of course. 

    That’s what happened with a recent road stabilization project in Santa Barbara County.  This unique application utilized 810 tons of tire-derived aggregate to backfill a retaining wall composed of large, rock-filled, welded wire baskets called gabions. 

    In March 2018, CalRecycle awarded the county $158,241 in Tire-Derived Aggregate Grant Program funds to purchase the TDA material. 

    Prior to the project, failed soil in the embankment caused erosion to the old roadway and shoulder. The ongoing failure also created large cracks in the asphalt surface.

    But the new retaining wall is expected to have longer staying power due to the TDA material. UC San Diego researched the road repair technique and determined that TDA is seismically safe for retaining walls and for road repairs and will not degrade due to poor underlying soils or saturated conditions.

    For more information about this project, read our press release and watch our video, which includes some outstanding drone shots recorded by Santa Barbara County Public Works.

  • CalRecycle March Monthly Public Meeting

    small CalRecycle logo

    Show up or tune in to CalRecycle’s monthly public meeting and find out what we’re up to!

    Hear about our upcoming education campaign to increase recycling and reduce contamination in curbside collections, so that material you’re tossing in your bins can actually be recycled into great new things.

    We’ll also discuss some recent grant awards, including a few to support our Beverage Container Recycling (CRV) Program, and a few more to clean up sites under our Solid Waste Disposal and Codisposal Site Cleanup Program.

    Another grant, to Yolo County, will support a project that will use 1.1 million passenger tires to offset the amount of wood chips and soil that would otherwise need to be used as ground cover at its new 20-acre waste-processing facility. That’s quite a few tires that will be put to good use rather than landfilled or illegally stockpiled. Remember that huge pile of tires that burned for years? We do—in fact, that fire was the impetus for our waste tire management program.

    CalRecycle March 2019 Public Meeting
    10 a.m. Tuesday, March 19
    Byron Sher Auditorium, CalEPA Building
    1001 I St., Sacramento, CA
