Guam Looks to Green Infrastructure

The Guam Environmental Protection Agency (GEPA) is working with engineering firm CH2M Hill/Jacobs Engineering to boost the island’s sustainability by greening its infrastructure. In particular, The Guam Daily Post reports, the agency is looking to promote the use of recyclable materials in road construction. Although the report doesn’t include many details.  However, given that asphalt… Continue reading Guam Looks to Green Infrastructure

NAPA Issues New Thinlay Guidance

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

Structural Design Guidelines for Porous Asphalt Pavements (July 2018)

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)
