Design Catalog for Non-DOTs
This design catalog, published March 2025, provides a simple, straightforward approach for new and reconstructed asphalt pavement designs for non-state DOT roadway applications using recognized procedures. It is timely, not only in meeting recent legislation and federal aid requirements, but also in addressing the local agency needs for developing reasonable and applicable pavement design recommendations.
Tools
NAPA’s free tools help contractors provide smooth, safe, durable asphalt pavements.
Economic Impact of Rehabilitation
Developed by Auburn University, this Excel workbook quantifies road user, crash mitigation, and local business impact costs to help quantify project-specific costs associated with the rehabilitation of a roadway. Using nationally transferrable data representative of driver behavior this workbook simulates and calculates the economic impact of construction in a community.
MultiCool/PaveCool
A user-friendly application that calculates the rate of cooling in the mat during construction.
Quantity Calculator
Helps with asphalt material quantity calculations and job site measuring.
PAVEXpress
A web-based software created to design flexible and rigid pavements using AASHTO 93/98.

Publications
Construction
Construction quality is crucial to long-term pavement performance. Surface preparation, placement, joint construction, and compaction affect pavement performance. Learn how to construct asphalt pavements with our Quality in Construction series.
Materials
Asphalt pavement material is a precisely engineered product composed of about 95 percent stone, sand, and gravel by weight, and about 5 percent asphalt cement. Material selection makes an impact on the durability of asphalt mixtures.
Production
Learn about industry best practices for producing high-quality mixtures.
Recycling Agents
NAPA’s latest Quality Improvement Publication (QIP) 131, Practical Guide for Using Recycling Agents in Asphalt Mixtures, provides a tiered set of step-by-step approaches to facilitate the use of recycling agents to produce asphalt pavements with good performance and to promote sustainability.
