In 1997, Texas mixed discarded roofing shingles into two 1,000-foot Highway 31 test sections

Engineers in Texas have made groundbreaking progress by recycling discarded roofing shingles into robust road surfaces. After extensive testing, these innovative materials showed they could match the performance of conventional asphalt, enduring significant traffic wear. The success of this pilot program also spurred the implementation of state-wide regulations that promote the use of recycled shingles in highway construction, leading to both cost savings and conservation of natural resources.
