Road Construction

Construction of roads involves the paving, rehabilitation, and/or reclamation of degraded pavements in order to achieve a state of good repair and increase road traffic safety. Road construction involves the use of asphalt, liquid asphalt, concrete, soil stabilization, rebar, paving and pavement recycling machines, and other road repair materials. Get price

Different Types of Road Surface Material and Construction

Aug 30, 2016Since early 1920s, asphalt road surface construction is the most popular type. Asphalt construction technique gives a layer of thick gravel base on top. ROI of this type of road construction includes low noise during pavement, relatively low cost material, and top one is easy to handle for maintenance and repairing. Get price

4. ESTIMATING ROAD CONSTRUCTION UNIT COSTS

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. An average production rate in common material (no rock Get price

Top Five Common Road Construction Methods

The most common modes of construction are Earth road method, Gravel road, bituminous road; water bound macadam and concrete cement method. Earth road method. This technique is most popular in semi-rural and rural areas. The raw material used is earth like the name suggests. It does not require much skill for it to be put into place. Get price
