The Study and Estimation of Accurate Performance of Road Construction Machinery by Construction Management Approach

Analysis of the construction costs is very important to select the proper kind of plan and maintenance by the minimum costs and accurate using of machineries. This analysis is considered as an essential tool for decision making about investment on modern and existed technics. Therefore, perception of the effect of road optimum construction costs is significantly important, and related advantages to regular and periodic repairs are tied to this relationship [1]. Therefore, this research tried to study the effect of repair and maintenance cost and proper usage of these machineries in road construction on road users cost for Iran roads network. In this regard, the effective factors are subordinate of cost of road users for the selected road network. One million Rial increase in the cost of improving the road administration reduces daily performance cost of a vehicle 0.72 Rial per kilometer. The effect of improvement cost on road users’ cost is reducing with a reduction rate. In other words, huge investment to reduce users’ cost can’t be justifiable. Using criterions, regulations, and standards in designing, execution, utilization, and maintenance steps of civil projects are significantly important for technical and economic justification of designs, designing quality, execution (useful life), utilization, and maintenance costs. State executive and technical system has seriously emphasized on applications of technical criterions, standards, and regulations in publications in design preparation and execution, and also necessary attention to maintenance costs of designs.
