Bonded Concrete Overlay: Route 67, Jefferson County
A bonded concrete overlay using a 'Fast Track' high early strength paving mixture was constructed on Route 67, Jefferson County in 1990. There are 18 Missouri Test Sections (Mo. TS) located in the overlay project. This report will solely focu on Mo. TS-3 through Mo. TS-13 plus two additional test sections added to the investigation since construction. The 11 Mo. test sections consisted of several construction variables. The variables were pavement thickness, surface prepartation, use of neat grout and use of blankets. The pavement thickness varied from 3, 4 or 5 inches. The pavement surface was either shotblasted, milled-shotblasted, or milled-sandblasted. The two additional test sections are as follows. An area of original pavement widened from 2 to 4.25 feet with PCCP. The overlay was 4 inches thick with neat grout and a varied surface preparation. The other area was a 4-8 inch concrete overlay on top of a milled asphalt overlay. The investigation showed the pavement with the 4-8 inch concrete overlay on top of a milled asphalt exhibits the best overall performance. The pavement that was shotblasted prepared showed the greatest amount of deteriorations of the test sections. The 3-inch overlay test sections have performed better than the 5-inch overlay test sections. The application of grout appeared to decrease the moderate and high severity transverse cracking in several of the test sections.
