abstract = {Soil stabilization is the alteration of soils to enhance their physical properties and can be utilized on roadways, parking areas and many other situations where sub-soils are not suitable for construction. The use of conventional stabilizing agents have improved the engineering properties of lateritic soil but the cost of these stabilizing agents are on the increase, therefore there is need for alternatives such as palm kernel shell. The lateritic soil used in this study was taken on the sedimentary formation located at Abalabi (  53’ 13.758”N,   7’ 59.994”E), along Papalanto-Ilaro road, Ogun State, Nigeria and palm kernel shell wastes were taken from oil palm producing plant at Iweke along Ilaro-Owode Road, Ilaro, Ogun State, Nigeria. The palm kernel shells were broken into pieces passing through 5mm sieve and then substituted for lateritic soil in the range of 0% to 50% at 5% intervals for compaction test while 0% palm kernel shell 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, maximum dry density reduces as the percentage palm kernel shell substitution increases while optimum moisture content increases as the percentage palm kernel shell substitutions increases. Therefore palm kernel shell could be used for the construction of road and as a result, environmental risk and hazard caused by palm kernel shell waste could be reduced if not completely eliminated.

abstract = {This study is aimed at investigating the possibility of using thermoplastic as an alternative for construction materials with a view to turning waste to job opportunities rather than problem or nuisance. The laterite used in this study was taken at Ajegunle, Abalabi (6 53’ 13.758”N, 3 7’ 59.994”E) along Papa-Ilaro road, Ogun State, Nigeria and the solid thermoplastic wastes were taken from a plastic recycling plant at Papalanto (6 53’ 26.406”N, 310’ 21.788”E), Ogun State, Nigeria. The thermoplastic waste were grounded into pellets passing through 5mm sieve and then substituted for lateritic soil from 25% to 50% (at 5% interval) for soaked and unsoaked California Bearing Ratio (CBR) test in line with BS 1377 (1990) while 0% served as control experiment. The tests conducted are soaked and unsoaked CBR. From the results, it was observed that plastic pellet stabilized soil exhibit the same CBR characteristics as lateritic soil while CBR value increases as percentage of plastic pellet increases for both soaked and unsoaked from 25% to 50% substitution. Based on the results of this study, plastic pellet could be used as a substitute as well as stabilizing agent in lateritic soil for road construction materials. Therefore, environmental risk and hazard caused by plastic waste could be greatly reduced if not completely eliminated.
