SIXTEENTH PROGRESS REPORT ON THE ROLLING-LOAD TESTS OF JOINT BARS

Seven tests using 115 RE bars with easements on the top bar surfaces to depths of approximately 0.220 and 0.110 in were completed. The shallow easements were effective in eliminating gouging of the bars by the rail ends. Six joints with shallow easements averaged 349,080 cycles. Twelve tests of joints using 132 RE bars with the same type of milled easement were completed. Two bars with deep easements failed. The shallow easements were effective in preventing gouging of the bars. Average cycles for failure for 6 joints with deep easements were 611,630 and average cycles for failrue for 6 joints with shallow easements were 583,530 cycles.
