The tests conducted in line with BS 1377 (1990) are sieve analysis, plasticity index determination, compaction, soaked and unsoaked CBR. From the results, it was observed that plastic pellet stabilized soil exhibit the same strength characteristic as lateritic soil while CBR value increases as percentage of plastic pellet increases for both soaked and unsoaked from 2% to 10% substitution. Consequently, plastic pellet could be used as a substitute as well as stabilizing agent in lateritic soil for construction material.
