ROAD CONSTRUCTION

Road work is a necessary and very important part of building of an infrastructure of various objects. Their working life and safety depend on quality of road construction.

On laying out a new road certain general principles have to be kept in mind. A careful survey of two or three trial lines should be made before the route is finally decided on. This involves also an examination of geological features of the district and of streams which have to be crossed by bridges. It all requires a great engineering skill.

It is important to be well acquainted with the nature of the country which is to be traversed. It is equally important to consider the weather conditions. To make tunnels, embankments, foundations for bridges, constructing canals or roads it is necessary to know the character of the rock met with, especially whether hard or soft and whether permeable or not to water.

Road construction is a multistage process that includes excavation works, asphalt coating and timely repair of roads. Each stage should be carried out in a skillful way. External esthetics of roads as well as the safety of all road users, that is the most important thing, depends on it.

Modern machinery enables to reduce considerably terms of work performance. High technologies enable to carry out road building works all year round. Asphalt paving and improvement of territories make life more comfortable and provides high wear resistance. Nowadays a car is not a luxury and good roads and safe sidewalks are especially important.
