CC2 Phase IV Post-Traffic Testing Results and Analysis

 

 

 

After testing, field samples were taken for post-traffic testing from two slabs per test section. A total of 48 cores and 54 sawed beams—eight cores and nine beams per section—were taken after traffic was completed. Three of the cores were tested for compressive strength and the remaining five for split tensile strength. The beams were saw cut for flexural strength testing—three beams cut from the top of the slab, three from the middle and three from the bottom of the slab). The average post-traffic laboratory results are compared to the initial results obtained from the molded beams and cylinders.

Sawed Beams and Cores

A total of 48 cores and 54 sawed beams were taken from the test items as soon as the traffic was completed. Two slabs per test item were cut (concrete mix placed in two phases). Eight cores were drilled and nine beams saw cut per slab in the north side of each test item. Three of the cores were tested for compressive strength and the remaining five for split tensile strength. The beams were saw cut for flexural strength testing (three beams cut from the top of the slab, three from the middle and three from the bottom of the slab). The average post-traffic laboratory results are compared to the initial results obtained from the molded beams and cylinders and presented in Table 1.
