The aim of this research is to determine appropriate correction coefficient of production machine to be considered during the construction of pavement in Republic of Benin. Given that reliable construction project should be in accordance with appropriate services and workmanship, this research proposes a method to be followed for the choice of machines according to the nomenclature of all the tasks necessary for the construction of a pavement. Then, a method for determining the actual production of machinery to be used on the job site while listing some factors to consider in determining prices. Based on the maximum theoretical production of the machines used during construction works, this research shows that improving the soil’s performance depends on the quality and the machines’ performance. Additionally, the results show that, the machines’ theoretical productions must be corrected by appropriate factors linked to the conditions under which the works will be executed. Consequently, for a reassuring determination of the machines’ operating cost, this research proposes that the machines to be used will work under challenging conditions.
