NAPA releases update to heavy duty pavement publication

To aid in specifying and building asphalt pavements for severe loading conditions, the National Asphalt Pavement Association (NAPA) has released an updated second edition of Design & Construction of Heavy-Duty Pavements (Quality Improvement Series QIP-123). The new publication covers structural design, material selection, mixture design, production, construction, and quality control considerations for heavy-duty asphalt pavements, including discussion of large-stone mixes, which can be an economical solution for these applications. The book is available as a PDF download through the NAPA Online Store.
