The effects of truck platooning on the nation’s infrastructure continues to be studied, federal officials told the American Society of Civil Engineers’ International Conference on Transportation and Development here. Derek Constable, a bridge management engineer for the Federal Highway Administration, said the agency has a research project underway to investigate platooning’s impact on structural safety,… Continue reading Platooning Continues to Be Put Under Microscope at Federal Level
Rep. Earl Blumenauer, D-Ore., Tuesday introduced the Rebuild America Act of 2019, which would incrementally increase the federal gasoline and diesel taxes to invest in America’s infrastructure. The legislation raises the fuels tax by five cents a year over five years, indexes it to inflation, and establishes Congress’ intention to replace it with a more… Continue reading Oregon lawmaker introduces bill to raise gas tax, eventually linking it to inflation
U.S. state governments face growing challenges attracting, building and retaining critically important talent and workforce skills, according to research by the National Association of State Chief Administrators, conducted in collaboration with global consulting company Accenture and human resources provider NEOGOV.

Thinlays are a suite of thin-asphalt overlays designed specifically for pavement preservation. With Thinlays, agencies can extend the life of pavements that are in good to fair condition, decreasing life-cycle costs, improving ride, and decreasing roadway noise. The guide, Thinlays for Pavement Preservation (Information Series 141), provides comprehensive guidance on the proper use of Thinlays,… Continue reading NAPA Issues New Thinlay Guidance

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 516: Tack Coat Specifications, Materials, and Construction Practices provides state agencies across the United States with guidance as they reevaluate their tack coat specifications, the materials they use, and the practices by which the tack coats are placed.… Continue reading Tack Coat Specifications, Materials, and Construction Practices
Often the design of porous asphalt pavements is focused on how well the pavement will handle water, not traffic. For most parking lots and light-duty surfaces this may be a reasonable approach, but as public agencies look to use full-depth porous asphalt pavements on roadways a traditional structural design methodology is needed. Written by Charles… Continue reading Structural Design Guidelines for Porous Asphalt Pavements (July 2018)
