Info

It is desirable for a patch material to have an equal or lower permeability than anyconcrete it is being placed on top of (i.e. the existing pavement), to avoid the buildup ofwater at the concrete interface. The permeability test results are shown in Table 11 below.The Denka CSA #20 (Sample 4) and Tetraguard AS20 (Sample 10) were generally lesspermeable than the control. The patch materials containing Type K cement andKomponent (Samples 2 and 3), on the other hand, were more permeable than the control.The permeability of the Type K cement modified material was, in fact, so high that the 7-day and 28-day tests were terminated to prevent damage to the testing equipment.MODIFIED PATCH CHARGE CHLORIDESAMPLE MATERIAL SAMPLE PASSED, Q IONNUMBER DESCRIPTIONS AGE (Coulombs) PENETRABILITY123410Table 11.

- 5.2.6 Concrete-to-Concrete Bond Strength -To determine the concrete-to-concrete bond strength, spare blocks (12 in. x 12 in. x 3 in.)of 1-year-old standard Portland cement concrete (PCC), were prepared in a similarmanner as the concrete pavement slots in a DBR project. The top faces of the blocks werebeadblasted, blown clean with compressed air, lightly sprayed with water, and overlaidwith 2 inches of the various concrete patch materials. After curing in a moist storageroom for 28 days, three 4-inch diameter cores were cut from each block. The cores were5 inches thick, consisting of 3 inches of old concrete and 2 inches of the patch material(see Figure 17 below).Figure 17. Core for Iowa Shear Test2 in. Modified Mn/DOT 3U18 PatchMaterial, 28 Days Old3 in. Standard PCC,Approximately 1 Year OldThe Iowa Shear Test 10 was performed by placing the cores into a shearing device andapplying a load at a constant rate of increase (i.e. 50 psi/sec) until the bond between thetwo types of concrete broke (see Figure 18 on the following page).10 Iowa 406-C, Method of Test for Determining the Shearing Strength of Bonded Concrete32
