THE PROBLEM OF CORROSION OF LOAD TRANSFER DOWELS

THE OBSERVATIONS OF DOWEL PERFORMANCE ARE IN TRANSVERSE EXPANSION JOINTS ON CONNECTICUT PAVEMENTS OF AN EARLIER DESIGN ARE REPORTED ON, NAMELY 100-FT SLAB LENGTH WITH THREE INTERMEDIATE WARPING JOINTS. THE CONDITION OF DIFFERENT TYPES OF HOTROLLED DOWELS AND BEAMS REMOVED FROM PAVEMENTS OF VARYING AGES ARE DESCRIBED. IN A FURTHER ATTEMPT TO EVALUATE VARIOUS MODERN, RUST-RESISTANT COATINGS AND CLADDINGS, STANDARD ABRASION AND SALT SPRAY TESTS WERE PERFORMED AT A COMMERCIAL LABORATORY. THOSE MATERIALS WITH PROMISE WERE USED IN ACTUAL FIELD INSTALLATIONS AND ARE UNDER OBSERVATION TO DETERMINE THEIR EFFECTIVENESS IN PREVENTING SEIZURE DUE TO CORROSION. THESE INSTALLATIONS ARE IN PAVEMENTS OF THE MORE RECENTLY ADOPTED 40-FT CONTRACTION JOINT DESIGN. SIMILAR RUST-RESISTANT DOWELS WERE PARTIALLY CAST IN CONCRETE AND SUBMITTED TO ACCELERATED TESTS IN A TIDAL AREA. THE CONDITIONS PERTAINING IN THE VARIOUS TEST INSTALLATIONS IN LATE FALL 1959 ARE DESCRIBED. /AUTHOR/
