Abstract
As the demand for construction materials increases, the need to find alternative construction materials that are readily available and cheaper is imperative. This research attempts to explore the recycling of waste plastic as a complete replacement for the Portland cement used in the production of pavement interlocking paving stones.
 Three specimens were produced, by varying the ratio of the waste plastic with the fine and coarse aggregates. The content of melted waste plastic in specimens A, B, and C was 33%, 29%, and 20% respectively. The specimens were crushed to determine their compressive strength. Specimen A having 33% melted waste plastic had the highest compressive strength of 25.7 N/mm2, For effective binding with the aggregates, the melted waste plastic should not be less than 30% of the mixture.
