ELEVENTH PROGRESS REPORT OF THE ROLLING-LOAD TESTS OF JOINT BARS

This report discusses the test program of rolling load tests of joint bars using 3-33 inch stroke rolling machines. The results of the tests of joint bars, which were heat treated and tempered are given. Hardness tests of the bars are included as well as the rolling load tests. Test results of 132 RE leadfree bars (oil quenched) averaged 573,100 cycles before failure which started at a rail end. Tests of 132 RE leadfree bars (water quenched) averaged 365,300 cycles. 4 bars failed, 2 from the top, 2 from the base.
