A SYSTEMS APPROACH APPLIED TO PAVEMENT DESIGN AND RESEARCH

PAVEMENT STRUCTURES ARE COMPLEX PHYSICAL SYSTEMS, WHICH IN THE PAST HAVE BEEN SOLVED PIECEMEAL WITH THE RESULT THAT MANY ASPECTS OF THE PROBLEM HAVE BEEN OVERLOOKED. BECAUSE OF THE OVERALL COMPLEXITY OF THE PROBLEM IT HAS BECOME EVIDENT THAT REALISTIC ANALYSIS OF PAVEMENT DESIGN PROBLEMS CAN BE OBTAINED ONLY BY LOOKING AT THE TOTAL PAVEMENT SYSTEMS, I.E., THROUGH SYSTEMS ANALYSIS. THIS REPORT DESCRIBES SUCH AN APPROACH, ONE IN WHICH A WORKING SYSTEMS MODEL IS PRESENTED WHICH UTILIZES MORE THAN FIFTY PHYSICAL INPUTS WHEN ANALYZING A PAVEMENT DESIGN PROBLEM. THE OUTPUT OF THE METHOD INVOLVES A SET OF RECOMMENDED CONSTRUCTION AND MAINTENANCE STRATEGIES BASED ON LOWEST TOTAL COST. THE PAVEMENT DESIGNER IS FREE TO SELECT HIS DESIGN FROM THIS ARRAY USING APPROPRIATE WEIGHTING FUNCTIONS IF HE FEELS THEM NECESSARY. THE REPORT DISCUSSES POSSIBLE WAYS THIS INITIAL WORKING SYSTEM CAN BE UTILIZED TO ESTABLISH AN OVERALL SYSTEM OF PAVEMENT ANALYSIS AND RESEARCH IMPLEMENTATION. A DISCUSSION IS ALSO PRESENTED CONCERNING THE FACTORS NECESSARY TO PUT THE DESIGN SYSTEM INTO PRACTICE. A PROPOSED ORGANIZATION IS PRESENTED FOR OBTAINING AND UTILIZING INPUT INFORMATION AND STORING PERFORMANCE DATA FOR FUTURE USE. IN ADDITION, A POSSIBLE PLAN FOR IMPLEMENTING THE APPROACH INTO THE TEXAS HIGHWAY DEPARTMENT DESIGN METHOD IS DISCUSSED. THE FINDINGS OF THE FIRST YEAR OF EFFORT IN THIS PROJECT ARE PRESENTED AND DISCUSSED. THE REPORT CONCLUDES THAT A SYSTEMS APPROACH TO PAVEMENT DESIGN RESEARCH IS FEASIBLE AND SHOULD BE PURSUED IN AN EFFORT TO DEVELOP MORE COMPREHENSIVE PAVEMENT MANAGEMENT TECHNIQUES. /AUTHOR/
