At a Glance

Fairfax County is piloting a new method for paving roads to reduce wear and tear, and meet sustainability goals. Uniquely, the pilot was made possible through crowdfunding!

Problem Addressed

For Fairfax and many other cities, more water means a higher cost of road maintenance and repairs. Water infiltrates voids between traditional stone road bases beneath asphalt surfaces, compromising the substructure and creating potholes.

Fairfax County used/is using an innovative paving method to address this/these challenge(s).

Solution(s) Used

A new pilot project at Fairfax County’s I-95 landfill complex is testing the viability of using a mix of recycled materials to construct and repair failing roads as part of the county’s overall push to deploy Smart Cities technologies. The county has partnered with the Virginia Department of Transportation to test Matrix Materials’ proprietary blending and construction technique. The project will study the mix’s durability and performance throughout the life cycle of the road.

The pilot project is replacing an approximately 200-yard length of failing roadway at the landfill complex. The road, which was scheduled for repair, is an ideal location to test new materials because the road is on county-owned property and on-site groundwater monitoring and controls are already in place, and the road is traversed daily by heavy dump trucks, excavators, and loaders.

Two material blends are being tested: a 40/60 mix of ash and crushed glass, and a 25/75 mix of ash and recycled concrete. Ash, glass and concrete used for repaving were sourced locally from a landfill complex. Which means the project is also helping the city meet goals to reduce use of natural resources and explore more environmentally friendly construction options. Staff from the Solid Waste Management Program are installing the road mix with guidance from Matrix Materials. Approximately 400-500 tons of recycled material are being used to fill 2,000 square yards of roadway.


  1. The project is using approximately 25% less material, meaning the construction phase was faster and cost less than a traditional method

Something Unique

To fund the pilot, Matrix Materials secured crowdsourced funding via Infrashares - a platform specifically designed to help individuals invest in local infrastructure projects.

Who Should Consider?

Any city looking to explore more environmentally friendly construction options, but with limited budget can use the crowdfunding platform to support innovation.
