An Overview of Surface Rehabilitation Techniques for Asphalt Pavements: Instructor's Guide

This instructor's guide is developed for a 3- to 6-hour long workshop on surface rehabilitation techniques for asphalt pavements. This workshop will be useful to Federal Highway Administration (FHWA), State, and local highway engineers and managers involved with the selection, design, and construction of thin surface rehabilitation techniques. Nearly all highway agencies use some kind of conventional surface rehabilitation technique (such as chip seals, cold mixtures, and thin hot mix overlays) to maintain and extend the service life of their asphalt pavements. The application of these techniques, however, has generally been limited to low-volume roads. In addition, information on design, construction, and performance is often scattered, and evaluations are usually incomplete or not documented. This guide discusses various types of conventional surface rehabilitation techniques, along with many of the emerging techniques. The discussion encompasses design, construction, cost, and performance (where available) of each technique. Recent efforts to gather and transfer information on thin surface technology are also briefly discussed including the Strategic Highway Research Program's efforts and FHWA implementation activities in the preventive maintenance area.
