Dry Lean Concrete (DLC) with temperature reinforcement in the form of 8 mm dia TMT bars spaced at 300 mm centre to centre both ways ( A view of the DLC laid over the road in shown in Fig. 60). During the construction of concrete roads with slip form paver, the difficulty was faced due to the presence of reinforcement, as the compaction of concrete
concrete mixture with an interwoven matrix of fibers. This also improved the tensile strength of the pervious concrete. The delayed set modifier resulted in a more fluid mix and in large gains in compressive strength at seven and fourteen days. This admixture may inhibit some of the cement from setting around aggregates and
