What is the unit cost of road construction in dollars per kilometers?
4.1 Introduction – The unit cost of road construction in dollars per kilometer is the sum of the subunit costs of the road construction activities. Road construction unit costs are estimated by dividing the machine rates by the production rates for the various activities involved in road construction.
How to calculate the earthwork cost of road construction?
4.4 Earthwork – The earthwork cost is calculated by estimating the number of cubic meters of common material and rock which must be moved to construct the road. The earthwork production rate is calculated as the cubic meters per hour which can be excavated and placed divided by the number of cubic meters per km to be excavated.
Road construction superintendents can often estimate the number of meters per hour that their equipment can build road based upon local experience after looking at the topography. The engineer’s method is to calculate the number of cubic meters to be excavated using formulas or tables for calculating earthwork quantities as a function of sideslope, road width, cut and fill slope ratios.
Production rates for bulldozers and hydraulic excavators are available. For example, a 6.0 meter subgrade on a 30 percent slope with a 1.5:1 fill slope and 0.5:1 cut slope with a one foot ditch and a 20 percent shrinkage factor would be approximately 2100 bank cubic meters per km for a balanced section.
An average production rate in common material (no rock) from an equipment performance handbook might be 150 bank cubic meters per hour for a 300 hp power-shift tractor with ripper. The tractor cost is $80/hr. The rate of excavation would be P = (150 m 3 /hr)/(2100 m 3 /km) =,07 km/hr UC = 80/.07 = $1143/km If the earthwork is not being placed or sidecast within 50 meters of the cut, the production rate for pushing the material to the placement location must be made.
Scrapers or excavators and dump trucks may be used. Excavation rates in rock vary with the size of job, hardness of rock and other local conditions. Often there is a local market price for blasting. Estimates of blasting production can be made by knowing the size of equipment and the type of job.
What is involved in road construction?
Excavation And Clearing – The area where the road will be built must be swept of all vegetation, which means shrubs, trees and bushes must be removed. Excavation machines will also remove stones and rocks from the path of the future road. Control measures such as ditches, fences, and basins are used to keep the cleared area from eroding.
What is the difference between building construction and roads?
What are the direct and indirect effects of roads? – The biotic consequences of the following effects of roads are considered below: direct effects include roads as barriers, enhancement of dispersal, roadkill, and effects on habitats; indirect effects include results of the access that roads provide to previously inaccessible areas, changes in water and air quality,
