Aggregates And Road Construction

Road Aggregates for Construction Requirements

Aggregates form the major portion of the pavement structure. Bear stresses occurring on the roads and have to resist wear due to abrasive action of traffic. Aggregates are also used in flexible as well as in rigid pavements. Therefore, the properties of aggregates are of considerable importance to highway. The aggregates to be used in road construction, particularly

demand of aggregates in road constructions

Environmental Impacts from Road Construction The basic I-O table aggregates the road construction work into one sector, therefore it is a bit difficult to get the final demand of road construction work by sector. Moreover, the road construction industry is divided into several categories namely earthworks, pavement work, bridge works and other

11-09-2015· M W is the weight of dry aggregates minus weight of aggregates saturated surface dry condition. Thus, Water Absorption = (M W /M D)*100. The specific gravity of aggregates normally used in road construction ranges from about 2.5 to 2.9. Water absorption values ranges from 0.1 to about 2.0 percent for aggregates normally used in road surfacing.

Aggregates are also used as base material beneath the foundations and also a component of composite materials such as concrete and asphalt concrete, basically used in building and road construction. A stable foundation also needs the construction aggregates with uniform properties and also has a low-cost extender binding with more expensive cement or asphalt to form concrete.
