ABSTRACT
The management of plastic waste (whose generation is on the increase) poses a great challenge to environmentalists owning to its non-biodegradability. The research project aims at using waste plastic materials as binding groundmass in place of cement thereby producing pavement blocks that are more durable and more failure resistant than the existing cement derived pavement blocks(whose water absorption rate as well as moderate resistance to acidic condition is a major disadvantages). This also serves as a partial solution to the environmental and ecological challenges associated with the increasing use of plastics. Plastic wastes (PET and LDPE type) were melted at temperatures between 180˚C-250˚C and mixed in different proportions (by volume) with granite dust, sand and clay to produce sample paver blocks. The same mould was used to produce cement paver blocks. The sample blocks were subjected to Flexural test, acid test, test for compressive strength and water absorption test. Based on the four tests, comparison was drawn on plastic paver blocks against concrete paver blocks in terms of durability, corrosion resistance and viability. A fifth test (the oven test) was carried out on the plastic paver blocks to find out how much heat they could withstand before failing. Results obtained from both compressive and flexural tests showed higher strength and durability for plastic paver blocks against those made from cements. Results of water absorption test show abysmally low water absorption. The acid test shows that the plastic derived pavement blocks were more corrosion resistance than that derived from cement. The oven test shows that the blocks failed between 180˚C-220˚C. Based on these, it was be established that plastic paver blocks are more viable, failure resistant, cost effective and sustainable alternative to both cement paver blocks and asphalt paved roads.
