Influence of Asphalt Pavement Characteristics on Vehicular Rolling Resistance
Rolling resistance is typically considered to be the longitudinal force resisting a vehicle’s tires as they roll across the pavement surface. This concept is limited to ...
Benefits of Rehabilitating Concrete Pavements with Slab Fracturing and Asphalt Overlays
The benefits of using asphalt overlays for rehabilitation of Portland cement concrete (PCC) pavements are grounded in economics and long-term performance ...
Phase IV (2015-2017) NCAT Test Track Findings Report Available
Six cycles of research have now been completed at the NCAT Test Track, and the findings have helped sponsors refine their materials specifications, construction practices and pavement design procedures for asphalt pavements ...
Recalibration Procedures For The Structural Asphalt Layer Coefficient In The 1993 AASHTO Pavement Design Guide

Pavement thickness design in the U.S. has been predominantly empirically‐based since the 1960’s.  The American Association of State Highway and Transportation Officials (AASHTO) pavement design guides published from 1962 through 1993 were based primarily on the AASHO Road Test conducted ...


Material Selection Guidance for Asphalt Pavement Design
Over the years, the asphalt industry has developed and quickly adopted a number of innovative and sustainable materials and technologies (hereinafter referred to as materials) for use in flexible pavements. While sustainability is a broadly‐used term, within this report ...
Best Practices for Determining Life Cycle Costs of Asphalt Pavements
State highway agencies (SHAs) continually face important financial decisions when planning a new or reconstructed highway. For example, what is the initial investment for the highway? How much is needed periodically to maintain the highway in good pavement condition ...
