The traffic count took place from Monday 17th to Sunday 23rd September, 2012. Hourly average each day were 2417, 2053, 1839, 1566, 1876, 1292 and 854 respectively. The hourly probability distributions which range between 0.05 and 0.13 were also illustrated. The result showed that the traffic volume was high in the morning for all working days except Thursday but relatively low in the afternoon for all days. The traffic volume increased again in the evening for all days. The correlation coefficients relationship amongst days indicated both positive and negative coefficients separately for the paired-days. The correlation coefficients values ranges from -0.04 to +0.92. The study detailed flow pattern along the route...

Compressive strength and slump tests were performed on fresh and hardened concrete using two nominal mixes of 1:1:2 and 1:1½: 3 with the sand component being partially replaced with Crushed Granite Fines. Compressive strength values above 30 N/mm² and 35 N/mm² were obtained for nominal mixes of 1:1:2 and 1:1½: 3 respectively when sand was partially replaced with 25-37.5% Crushed Granite Fines. Based on the economic analysis of the test results, replacement of sand with 25-37.5% Crushed Granite Fines is recommended for use in concrete production.

IOSR Journal of Mechanical and Civil Engineering, 2014

Abstract: Sequel to continuous failure of structures all over the country, adequate knowledge of ... more Abstract: Sequel to continuous failure of structures all over the country, adequate knowledge of the geotechnical characteristics of underlying soils at construction sites has become very desirable for foundation design and construction of civil engineering structures. This study aims at investigating and establishing the sub-soil types and profile to determine the engineering characteristics of the underlying soils within the Ikorodu Campus of the Lagos State Polytechnic, Ikorodu, Lagos, Nigeria and recommend appropriate foundation and road pavement design. Forty Dynamic Cone penetrometer tests were performed alongside eight borings which were accomplished using percussion rig with augers. Representative soil samples were obtained and analyzed in the laboratory in accordance with relevant geotechnical engineering standards. Result of the study showed that the study area was found to consist of about 0.35m thick of organic top soil followed by 9m thick of reddish lateritic sandy clay. The study also revealed that the superficial lateritic soil has a bearing capacity ranging from 130 kN/m2 at 1.0m depth to 243 kN/m2 at 2.5m depth. Shallow foundation with bearing capacity of 150kN/m2 at footing depth not lower than 1.2m is recommended for general use within the campus. Maximum expected settlement is estimated at 27.84mm. Similarly, a CBR value of 7% is recommended as subgrade CBR value for road pavement design within the campus. Keywords: Geotechnical Properties, Subsurface-soils,, Foundation Design, Pavement Design, CBR.
