FINAL REPORT ON STATEWIDE RIGID PAVEMENT SURVEY - VOLS 1 & 2

IN 1959, MARYLAND UNDERTOOK A FIELD SURVEY OF ALL THE RIGID PAVEMENTS IN EXISTENCE IN THE STATE. THE FIRST SURVEY WAS COMPLETED IN 1960 AND A FOLLOW-UP COMPLETED IN 1966. DEFECTS IN EACH PAVEMENT SLAB WERE CLASSIFIED AS MAJOR OR MINOR - (1) INNER OR OUTER CORNER BREAKS, (2) TRANSVERSE OR LONGITUDINAL JOINT SPALLS, (3) LONGITUDINAL OR TRANSVERSE CRACKS, AND (4) END FAILURES, ALL ACCORDING TO PREDETERMINED SURVEY DEFINITIONS. AN UNSUCCESSFUL ATTEMPT WAS MADE TO CORRELATE PAVEMENT ROUGHNESS WITH THE VARIOUS DEFECTS. RUDIMENTARY COMPARISONS WERE MADE BETWEEN DEFECTS AND DESIGN, CONSTRUCTION, PAVEMENT PROPERTIES, TRAFFIC AND ENVIRONMENT. THE CONCLUSIONS ARE NECESSARILY VAGUE BECAUSE OF THE INFLUENCE OF THE MANY UNCONTROLLED VARIABLES. RELATIONSHIPS BETWEEN DEFECTS AND AGGREGATE TYPE, SUBBASE TYPE, SHOULDER TYPE, CURING METHOD, JOINT FORMATION TECHNIQUE, AND PAVEMENT THICKNESS ARE ALL EXAMINED. SPECIAL SECTIONS OF THE REPORT ARE DEVOTED TO DESCRIBING SPECIAL EXPERIMENTS WHICH WERE ESTABLISHED TO INVESTIGATE (1) PAVEMENT GROWTH IN THE FIELD AND LABORATORY, (2) BLOW-UPS, (3) NEW JOINT SEALS, (4) CONCRETE OVERLAYS, AND (5) AVERAGE STRENGTH AND DENSITY OF PAVEMENT CONCRETE. VOL. 2 IS AN APPENDIX AND CONTAINS THE TABULATED INFORMATION FROM THE SURVEY. THIS FINAL REPORT WAS PRECEDED BY A REPORT ON THE RESULTS OF THE FIRST SURVEY AND EIGHT (ONE FOR EACH DISTRICT OF THE STATE AND A SUMMARY) REPORTS ON THE SECOND SURVEY. /BPR/
