Abstract

SOME COMPACTION STANDARDS AND QUALITY OF COMPACTED SOIL

Abidemi O. Ilori*

ABSTRACT

Three different compactive efforts, modified AASHTO, British Standard Heavy, and West African Standard were applied to three construction soil aggregates obtained from different aggregates sources in Uyo, in Akwa Ibom state, South eastern Nigeria. The soil aggregates satisfy the requirements for both subgrade and subbase stipulated by United States Unified Facilities Criteria and Nigerian Federal Ministry of Works. All the soil classify as SC (clayey sand), with various percentages of fines passing sieve no 200. The object is to investigate the quality of soil produced by the different compactive efforts. The modified AASHTO effort results in maximum dry density values of 1930 kg/m3, 1890.4 kg/m3, 1890 kg/m3, for samples from Uniuyo, Ukana, and Nsukura aggregates sources respectively. These values represent the highest values obtained for all the standards. Unconfined compressive strength, modulus, and California Bearing Ratio were further determined to evaluate the strength of the compacted samples. Results indicate that soil with maximum dry density values does not necessarily have the largest values of the strength parameters as indicated by poor correlation results between the maximum densities and stiffness or strength parameters.
