Engineering geological appraisal of relative stability of Akure – Ondo Highway segment of F-209, Southwestern Nigeria: Post-Construction analysis

Main Article Content

Abstract

The study examined the relative stability of Akure – Ondo which is a segment of F-209 Highway in Ondo State, southwestern Nigeria using geoengineering method. Investigation showed that the pavement is founded on sandy clay, sand and laterite. The average silica-sesquioxide ratio of the sample is 1.63 (lateritic soil type) with activity of 0.69 (inactive clay), while the clay mineralogy group is illite, and soaked California Bearing Ratio (CBR) is 12%. Thus, the thickness of the pavement should range from 325 mm (good segment) to 518 mm (for weak segment), which is far above the 192 – 316 mm existing thickness of the highway structure. In the upper 1.0 m, the subgrade structural number (SNG) coefficient for subgrade soil is higher than 0.5. The strength coefficient of the soil as subbase and base is less than 0.5. Therefore, based on these results, It can be concluded that the relative stability of the highway is due to its good engineering properties. The regression models of all parameters gave strong positive correlations for all the parameters correlated: soaked CBR and in-situ CBR, elasticity modulus and resilient modulus, in-situ CBR and resilient modulus, relative density and penetrative index, and relative density and in-situ CBR. However imminent failure is expected due to deficit in the design thickness and lack of drainage facility at the shoulders of the highway. The haulage activities along the highway have increased tremendous of recent; definitely it will affect the stability of the structure since its design-thickness will not sustain the present loadings on the highway in the long run.
