Components of Road Structure Functions and Construction

Construction: Constructed usually in two layers. Binder Course; Wearing Course (It is the layer which is in direct contact with the tyres of the vehicle) Functions of Surfacing of Road: Prevent penetration of water in to the pavement; Binder Course binds the Wearing Course with the Road

Road construction Designing Buildings Wiki

Road construction techniques were gradually improved by the study of road traffic, stone thickness, road alignment, and slope gradients, developing to use stones that were laid in a regular, compact design, and covered with smaller stones to produce a solid layer. Modern roads tend to be constructed using asphalt and/or concrete.

Pavement Layer an overview ScienceDirect Topics

CS was proposed for use in the construction of embankment and pavement layers of a road section of 1 km length. To decide the construction methodology to be adopted, three design mixes, (i) 100% CS mix, (ii) 50% CS–50% pond ash mix and (iii) 50% CS–50% soil mix, were proposed for use in the construction of a trial road
