Below is very brief road construction work method statement that outlines the complete process from laying the sub base to the laying of asphalt to achieve final product or outcome. The scope for pavement for the road construction consists of sub-base of granular material, road base of crusher run, asphaltic concrete binder course and asphaltic concrete wearing course.

Stone masonry:- The construction of stones bonded together with mortar is termed as stone masonry. Where the stones are available in an abundance in nature, on cutting and dressing to the proper shape, they provide an economical material for the construction of various building components such as walls, columns, tootings, arches, beams, etc..

One of the earliest applications was in the construction of highways where simple geotextile separators were placed between the sub-base and the subgrade to maintain the integrity of the stone layer.

Base course. The base course or basecourse in pavements is a layer of material in an asphalt roadway, race track, riding arena, or sporting field. It is located under the surface layer consisting of the wearing course and sometimes an extra binder course . If there is a sub-base course, the base course is constructed directly above this layer.

The aggregates to be used in road construction, particularly the aggregates used in the wearing course of the pavement should be sufficiently strong/ resistant to crushing to withstand the high stresses induced due to heavy traffic wheel loads. 2.

A good road base should cover the surface soil completely and be able support heavy vehicles evenly. And depending on the weight and amount of traffic and weather, the base can be as deep as thirty inches. Our rock base is made up of crushed concrete and stone screenings. No matter if you need rock base for a driveway or highway, we have the amount and quality you are looking for.

The sub-base should be compacted by a roller to provide an even surface.

Mostly, it is used as a construction aggregate in asphalt and concrete for road and highway work with or without a binder. Major uses of the cumulative crushed stone without a binder include railroad ballast #3 and road base. Cement and asphalt used in highway construction and general repair in residential and non-residential road development are composites used with a binder.

For more substantial developments, Highways England produces standards and documentation relating to the design, construction and maintenance of highways. For typical paths, tracks, drives and car parks, the sub-base layer can be built using a combination of materials such as a higher quality stone above and low grade crushed concrete beneath.

Thus, a cement concrete pavement is the most superior highway construction primarily from the point of view of strength and durability. The ingredients of the concrete mix, viz., the coarse aggregate (broken stone) and fine aggregate (sand) have to be selected carefully to satisfy the desirable properties for concrete-making. Potable water is generally considered satisfactory making cement
