This pilot will be the first test on a state highway.“California has set ambitious goals for recycling and other environmental priorities, and meeting them requires innovative and cost-effective solutions,” said Senator Ben Hueso, who has advocated for Caltrans to test this material. “Using waste plastic that was otherwise destined for a landfill will not only reduce the cost of road repair and construction but also increase the strength and durability of our roads. As a leader on environmental justice issues, California is uniquely positioned to transform the transportation industry once again by using this new technology that could revolutionize the way we look at recycled plastic.”Caltrans currently has a cold in-place asphalt recycling program that uses large machines to remove 3 to 6 inches of roadway surface and grind up the asphalt while mixing it with a foamed binding agent made of bitumen, a leftover sludge from oil refining. However, the recycled material used in this process is only durable enough to serve as the roadway base. Trucks need to deliver hot-mix asphalt from a production plant miles away and place a final layer over the base.Using this new technology developed by TechniSoil Industrial of Redding, a recycling train of equipment grinds up the top 3 inches of pavement and then mixes the grindings with a liquid plastic polymer binder, which comes from a high amount of recycled, single-use bottles. The new asphalt material is then placed on the top surface of the roadway, eliminating the need for trucks to bring in outside material for a paving operation. By eliminating the need to haul asphalt from the outside, this process can significantly cut greenhouse gas emissions.“We’re excited about introducing a new sustainable technology and helping pave the way for utilization of recycled plastics throughout the state,” said Caltrans District 3 Director Amarjeet S. Benipal. “This process is better for the environment because it keeps plastic bottles out of landfills and helps reduce greenhouse gas emissions and reliance on fossil fuels.”The $3.2 million paving project covers a stretch of Highway 162 between the Feather River and Christian Avenue in Oroville. The construction schedule is subject to change due to traffic incidents, weather, availability of equipment and/or materials, and/or construction-related issues.Tags :caltransenvironmentRecycled Plastic BottlesRepavingsustainabilityshare on Facebookshare on Twitteradd a commentStreet sweeping to occur next weekCity services: What’s opening soon?You Might Also LikeBriefsCalifornia State Treasurer Fiona Ma to Speak at Online Santa Monica College Commencement Ceremony June 25Guest Author10 hours agoBriefsLos Angeles Sheriff’s deputy accused of destroying evidence of 2019 assaultAssociated Press10 hours agoBriefsNewsBeach House Begins Community Re-Opening June 15Guest Author1 day agoBriefsNewsInput Invited for Marine Park Improvement ProjectsGuest Author1 day agoBriefsNewsPublic Health Emphasizes the Importance of Vaccinations as Distancing and Masking Guidelines Relax Next WeekGuest Author1 day agoBriefsNews“Righting Our Wrongs” performance on June 11Guest Author1 day agolast_img
