“San José is proud to receive this recognition from the Greenroads Foundation for the city’s ‘green’ transportation leadership,” says San Jose Mayor Chuck Reed. “From the installation of ‘smart’ LED streetlights to the construction of a 500-mile citywide bicycle network, ‘greening’ our transportation system is a major theme of the city’s ambitious Green Vision. We are pleased to be the first city in California to have a certified ‘green’ roadway project.”
The process used for resurfacing the road was “cold in-place recycling,” which involves pulverizing the top layer of asphalt, mixing it with an asphalt binder and using the recycled mixture to resurface the street. A new surface layer of rubberized asphalt, made up of ground recycled tires, is laid on top of this surface.
The Greenroads rating system is a collection of sustainable roadway design and construction best practices that address water, environment, access, community impact, construction practices and materials. There are 11 project requirements that must be completed in order for a roadway to be considered a "Greenroad," as well as 37 voluntary credits that a project team can choose to pursue. After a rigorous review process, the Greenroads Foundation assigns a project score based on the number of points earned by meeting the requirements and achieving credits. This score translates to one of four certification levels: bronze, silver, gold and evergreen.
