Thin asphalt overlays offer a time-proven method for extending the life of pavement structures that are still in serviceable shape. NAPA has a full suite of materials on thin overlays in a variety of formats which can be downloaded below. For your convenience, all these materials have been collected on one DVD, TAS-40, available in NAPA's online store.

IS-135, Thin Overlays for Pavement Preservation for web/email use
Thin asphalt overlays are popular approaches to pavement preservation because of their ability to provide improved ride quality, reduce pavement distresses, maintain surface geometrics, reduce noise levels, reduce life cycle costs and provide long-lasting service. This document provides guidance on when to choose thin overlays, how to select materials and design the mixes, construction and quality control, and what type of performance benefits to expect.
