• Abstract:
  The focus of this report is the process with which an expert system was developed to improve the design procedures of low-volume roads over expansive clayey soils. The guide combines numerical and engineering analyses with heuristic information about the site to recommend best design and construction practices. Numerical analysis is performed to predict longitudinal cracking distress, which was reported by a district survey throughout Texas to be one of the most prevailing distresses. Other common distresses are studied. Traditional and new remediation methods are proposed to address the problem of premature failure of low-volume roads on high-PI clays. Finally cost and benefit analysis are added to the design guide framework to complete the computer program and to accomplish the objectives of this project.
