SATELLITE TESTS ON THE NORTHEASTERN EXPRESSWAY I-95 (JOHN F. KENNEDY MEMORIAL HIGHWAY) VOLUME I

THE PRIMARY PRUPOSE OF THIS STUDY WAS TO OBTAIN BASIC DATA WHICH WOULD BE USEFUL IN THE APPLICATION OF THE AASHO ROAD TEST EQUATIONS TO PAVEMENT DESIGN IN THE MARYLAND-DELAWARE AREA. BASIC DATA WAS OBTAINED FROM FLEXIBLE AND RIGID PAVEMENT TEST SITES ON I-95. PAVEMENT MEASUREMENTS AND OBSERVATIONS WERE MADE PERIODICALLY FROM 1963 UNTIL 1970 AND INCLUDED ROAD ROUGHNESS, PRESENT SERVICE-ABILITY INDEX (PSI) DETERMINATION, BENKLEMAN BEAM DEFLECTIONS, AND SKID RESISTANCE. THE PRINCIPAL FINDINGS ARE PRESENTED IN VOLUME I, AND ADDITIONAL DATA IS GIVEN IN VOLUME II, APPENDICES TO THE FINAL REPORT. THE ROUGHNESS RESULTS SHOW THAT THE RIDEABILITY OF MOST OF THE I-95 TEST SITES WAS SATISFACTORY. RESULTS OF THE PSI SURVEYS INDICATE THAT THE PSI VALUES TEND TO DECREASE AS TIME (AGE) OF THE PAVEMENT INCREASED. HOWEVER, THE LAST PSI VALUES OBTAINED IN 1970 REMAINED AT HIGH LEVELS. DEFLECTION MEASUREMENTS ON THE FLEXIBLE PAVEMENT TEND TO INCREASE AS TIME OF THE PAVEMENT INCREASED. SKID RESISTANCE VALUES ON I-95 TEND TO DECREASE AS TIME OF THE PAVEMENT INCREASED. THE RESULTS OF THIS STUDY SHOW THAT THE PERFORMANCE OF THE TEST SITES HAS REMAINED AT HIGH LEVELS, THUS MAKING PERFORMANCE ANALYSES DIFFICULT. IT WAS THEREFORE NOT QUITE POSSIBLE TO ATTAIN ALL OF THE DESIRED RESEARCH OBJECTIVES. /FHWA/
