Shaking from the large earthquake that shuddered through Anchorage, Alaska last week was strong enough to turn smooth asphalt roads into broken, jagged depressions of rubble. But within just a few days, crews managed to repair the worst of the damage, unsnarling traffic in Alaska’s largest city. Click here for the rest of the article.
The asphalt paving industry is diverse in many ways, including ownership and business models. Hot-mix asphalt (HMA) producers include international, national, regional and local companies, each successfully filling the need for production and paving within individual economic environments. Even the country’s largest producer accounts for only about 10 percent of the total HMA tonnage produced… Continue reading Lakeside Industries Exemplifies Many Paths to Industry Success
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
The Daniel K. Inouye Highway (DKI), also known as Saddle Road (Route 200), is the most direct cross-island route between east and west Hawaii Island. People use the road for business travel, transport of goods and services, tourism, recreation, shopping and daily commuting. The August 2018 issue of the HAPI newsletter (click here) provides history… Continue reading The Transformation of the Saddle Road

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)
