Clay stabilization using flyash and carbide waste and its effect on the value of unconfined compression test (Case Study of National Park Ujung Kulon Road in Pandeglang Regency)

Abstract

Clay is a type of soil with high pore water characteristics which causes its problem for pavment. Ujung Kulon national Park road in Sumur Subdistrict, Pandeglang Regency is a road with clay soil type, so the road is often demaged. To overcome this its problem it is necessary to add strength and improve its bearing capacity.The water content of the sample taken from the compaction of the original soil standart proctor. The variation of fly ash mixture that used is 0% and 20% and carbide waste with a mixture of 0%, 5%, 10%, 15%, 20% and 25%. Based on the result, the soil which stabilized by fly ash and carbide waste in the variation of 0%, 10%, 15%, and 20% showed the increase of the value of the soil bearing capacity, and decrease the velue of soil plasticity index.the largest of UCT (Unconfined Compression Ssrenght) value result for soil sample mixed with 20% fly ash and 20% carbide waste contain by curing for 28 days in amount of 5,51 kg/cm2.
