Design of Concrete Pavement (A Case Study of Farm Road, Along Zaria-Sokoto Road, Nigeria) [ ]


The aim of this research article is to justify the use of concrete pavement and to design a good concrete pavement that will be durable and serve the community, for its design life without any failure or problem. A traffic count has been conducted to determine the Annual Daily Traffic Flow (ADTF). This was used to determine the growth rate at the design period, which was found to be 3% growth rate. The results were presented below: sub-grade type was normal; and the minimum thickness of the Sub-Base required was 80mm. While the minimum thickness of the concrete slab (unreinforced) required was 155mm. The cumulative number of common vehicles (Tn) was 0.44x106 cum.no.com.veh. The cumulative equivalent number of standard axle (T) was 0.2x106 standard axle. Materials such as cement content, fine aggregate, coarse aggregate, and water were determined as 1014611kg, 1623375.24kg, 2435067.36kg and 209kg/m3 respectively. The total estimated cost of cement, fine aggregate, coarse aggregate, and water were calculated as #15219750, #650000, #2435000, and #50731 respectively, amounting to #18,355,481 only.
