• Abstract:
  The information contained in this report represents data collected on over 80 seal coats in seven districts in Texas. The sections included variables such as a range of traffic concentration, climate and road surface conditions. All projects used in this study were constructed in 1982 and 1983. A preconstruction field evaluation of site involving a visual evaluation and surface texture test was performed. Specific construction data were gathered from district records which consisted of aggregate spread rates, asphalt shot rates, aggregate and asphalt sources and type. Postconstruction evaluations were conducted at intervals which allowed as many environmental cycles as possible. The data gathered in the course of this study provide the necessary information for further design method refinement and design. curve adjustments. Included in this report is the present seal coat design method.
