FIELD OBSERVATIONS ON EFFECTS OF JOINTS ON CRACKING AND OTHER DETERIORATION IN CONCRETE PAVEMENTS

DATA ON THE RELATIVE AMOUNTS OF TRANSVERSE CRACKING AND BLOWUPS EXPERIENCED IN CONCRETE PAVEMENTS CONSTRUCTED WITH AND WITHOUT EXPANSION JOINTS AND WITH VARYING SPACINGS OF TRANSVERSE CONTRACTION JOINTS ARE REPORTED ON. THE DATA WERE COLLECTED BY DETAILED SURVEYS ON SOME 450 MILES OF CONCRETE PAVEMENT SELECTED FROM A TOTAL OF 4,000 MILES SO AS TO BE AS NEARLY COMPARABLE AS TO AGE AND DESIGN AS WAS POSSIBLE. PAVEMENTS CONSTRUCTED FROM CHERT GRAVEL AND CRUSHED LIMESTONE COARSE AGGREGATE, BOTH REINFORCED AND UNREINFORCED, WERE INCLUDED. IN GENERAL IT WAS FOUND THAT INCREASE IN THE NUMBER OF EXPANSION JOINTS IN ALL TYPES OF PAVEMENTS SURVEYED RESULTED IN MORE TRANSVERSE CRACKS WITHOUT MUCH ADVANTAGE DUE TO ELIMINATION OF BLOWUPS. THE USE OF MESH REINFORCEMENT WAS ACCOMPANIED BY A SUBSTANTIAL DECREASE IN CRACKING. UNDER MISSOURI CONDITIONS THE USE OF CONTRACTION JOINTS AT SUITABLE INTERVALS IS VERY BENEFICIAL; EXPANSION JOINTS ARE NOT NECESSARY OR DESIRABLE WITH LIMESTONE AGGREGATES, BUT SOME PROVISION FOR EXPANSION IS CONSIDERED NECESSARY WITH THE CHERT GRAVEL PAVEMENTS IN ORDER TO CONTROL BLOWUPS. /AUTHOR/
