- Abstract
Recycling helps to reduce the pollution caused by waste and huge amounts of energy are used when making products from raw materials. Recycling requires much less energy and therefore helps to preserve natural resources in this case, natur (raw) rubber used in the production of plastic products. This study is aimed at providing alternatives use for plastic wastes in the construction industries. The lateritic soil used in this study was taken on the sedimentary formation located at Abalabi 6°53' 13.758"N, 3° 7' 59.994"E, Ajegunle, along Papalanto-Ilaro road, Ogun State, Nigeria and plastic wastes were taken from different locations in Ilaro, Ogun State, Nigeria. The plastic wastes were cut into pieces passing through 5mm sieve and then substituted for lateritic soil in the range of 0% to 50% at 5% intervals while 0% plastic pellet substitution served as control experiment. In line with BS 1377 (1990), compaction tests were carried out on the composite materials to determine the various optimum moisture contents and maximum dry densities at different test water contents for all the substitutions. From the results, it was observed that 0% plastic pellet substitution (i. e. control experiment) has the maximum dry density value. In addition to this, 35% to 40% plastic pellet substitution has the maximum optimum moisture content value while increase in plastic pellet substitution reduces the density of the composite material. The composite material at 10% plastic pallet substitution can be used for road base and sub base and it is therefore a possible alternative solution for safe disposal of the plastic wastes from causing nuisance. Therefore environmental risk and hazard caused by plastic waste would be greatly reduced, if not completely eliminated.
