pavement distress manuals, one for use with concrete and the other for use with asphalt pavement. Small and spiral bound, the manuals are designed for easy use in the field. They identify low-, medium-, and high-severity levels of each pavement distress with photos. Distresses are categorized by their cause: environmental, traffic, or construction.

The ultimate quality of your asphalt paving project is directly related to the experience, skill, and equipment of the contractor doing the work. Behind each contractor is a tremendous investment in equipment, highly skilled manpower, and a pride of workmanship in building asphalt pavement of the highest quality. Whatever the project,

The National Asphalt Pavement Association (NAPA) each year unveils its annual Quality in Construction Award winners. Though the ongoing global pandemic has removed NAPA's ability to hold its annual meeting in person this year, the association has nevertheless retained the breadth and depth of its annual awards program.. As in years past, Roads & Bridges brings you a look at some of the winners.
