In a developing country such as India, road networks form the arteries of the nation. A pavement is the layered structure on which vehicles travel. It serves two purposes, namely, to provide a comfortable and durable surface for vehicles, and to reduce stresses on underlying soils. In India, the traditional system of bituminous pavements is widely used. Locally available cement concrete is a better substitute to bitumen which is the by product in distillation of imported petroleum crude. It is

Whenever we think of a road construction in India it is taken for granted that it would be a bituminous pavement and there are very rare chances for thinking of an alternative like concrete pavements. The mix design has been done by trial and error method. The mix proportions are calculated as per IS code. The ingredients of concrete M30 grade proportion are shown below table3.4. The raw materials are mixed through hand mixing and compacted through the vibrators of casted cubes and beams. The total mixing time was 3 minutes; the samples were then casted and left for 24 hrs before demoulding .They were then placed in the curing tank. Water absorption capacity and moisture content were taken into consideration and appropriately subtracted from the water/cement ratio used for mixing. The w/c ratio is taken 0.5% for all the mixes. Hence, cement was replaced in percentages of 0%, 0.6%, 1.2%, 1.8% with Polypropylene fibre 150 × 150 × 150mm, Beam and Cylinder moulds were used for casting.
