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.
