Life cycle economic comparison between rigid and flexible pavement: a case study for the construction of wajen- garin barkamawa-dugurawa road in kano state nigeria

pavement design, such as using a concrete wearing course, a bitumen emulsion tack coat, a concrete binder course, and an MC 1 cutback bitumen prime coat. The expenditure associated with the construction of flexible pavement amounts to 1,760,293,155.18 N, while the anticipated cost for the construction of rigid pavement is projected at 2,725,765,337.00 N. In percentage terms, rigid pavement costs 64% more than flexible pavement. Flexible pavement costs are based on supply, construction, and finish unit rates. The projected flexible pavement cost includes labor, materials, and plant expenditures. Reinforcing and concrete costs are estimated in rigid pavement studies. The analysis examines plant, people, and permanent material expenses. The research gives detailed pavement structural design and construction cost estimates for the road project, enabling informed pavement structure decisions.
