DEVELOPMENT OF GUIDELINES FOR THE DESIGN OF PAVEMENT SUBDRAINAGE SYSTEMS FINAL TECHNICAL REPORT-PHASE I

THE OBJECTIVE IS TO DEVELOP GUIDELINES FOR PREVENTING DAMAGE TO PAVEMENTS CAUSED BY EXCESS WATER. THE PRINCIPAL FINDING ARE: (1) SURFACE WATER CANNOT BE PREVENTED FROM ENTERING STRUCTURAL SECTIONS; (2) PAVEMENTS ARE NOT IMPERVIOUS; (3) IMPROVED SEALING OF PAVEMENT JOINTS AND CRACKS IS NEEDED; (4) A HYDROLOGY ORIENTED METHOD IS NEEDED TO SOLVE SUBDRAINAGE PROBLEM; (5) A RATIONAL SUBDRAINAGE SYSTEM DESIGN IS NEEDED; (6) FILTER DESIGN CRITERIA RESEARCH IS NEEDED; AND (7) PAVEMENT DESIGN METHODS AND SUBDRAINAGE ARE RELATED. FIVE BASIC RECOMMENDATIONS ARE MADE: (1) A COMPREHENSIVE PROGRAM TO STUDY SUBDRAINAGE PROBLEMS BY SYSTEMS ANALYSIS IS NEEDED; (2) A REVIEW OF DESIGN METHODS SHOULD BE ACCOMPLISHED TO EVALUATE STRUCTURAL SECTION DISTRESS AND PAVEMENT FAILURE PHENOMENA; (3) RESEARCH SHOULD BE UNDERTAKERN TO GENERATE INFORMATION ON THE MECHANICS OF FILTER/ DRAINAGE MATERIALS; (4) INSTRUMENTATION OF PERFORMING SUBDRAINAGE SYSTEMS BE ACCOMPLISHED TO OBTAIN DATA RELATING TO RAINFALL, SNOWFALL, SOIL MOISTURE CONTENT AND DRAINAGE OUTFLOW; AND (5) TRIAL INSTALLATIONS OF IMPROVED SUBDRAINAGE SYSTEMS BE CONSTRUCTED AND TESTED TO DETERMINE EFFECTIVENESS OF THE SYSTEMS AND DEVELOP STANDARDS/SPECIFICATIONS FOR CONSTRUCTION. /AUTHOR/
