Abstract:

The Texas State Department of Highways and Public Transportation and the Texas Transportation Institute through their cooperative research program have developed a seal coat design procedure. This design procedure is based on a modification of the original Kearby Method (1) and includes separate design curves for seal coats made from lightweight aggregates and normal weight aggregates. A review of the historical development of this method has indicated that the design procedure has not been verified by a field performance study. Furthermore, field observations on normal weight aggregate seal coats have indicated that the design procedure calls for inadequate asphalt. In an attempt to determine the validity of the design and/or to alter the method, a field study was undertaken. This study consisted of visual evaluation of seal coat trial sections placed as a part of Research Study 2-6-71-83 "Synthetic Aggregates for Seal Coats". Details of this field evaluation and subsequent analysis of data are described below.
