The demand for Road construction equipment, both new and used is on the rise as speed of road construction has broken all its previous records, currently India is constructing around 22 km of roads per day. The government had allocated outlay of Rs 97,000 crore for road sector in budget 2016-17.
Further Ministry of Road Transport and Highways (MoRTH) has set the target to award works worth Rs 7 lakh crore in the next five years to develop National Highways of around 50,000 km.
This fiscal itself, National Highway Authority of India (NHAI) planned to award 97 highway projects worth Rs 1 lakh covering the area of 6,631 km and awarding the projects one after another.
The government’s commitment and investment in road sector indicate the better sale of Road Construction Equipment in the country.
Therefore, in this article, we will see the road building process and the major equipment used for road construction.
The road and highway building process mainly consists of three phases, first the rough grading (Earthmoving), second, the Fine grading (includes sub-grade preparation) and final phase of road construction is surfacing, which can contain concrete, gravel, asphalt or a combination of these.
Compaction is a main element of all road and highway building, adequate compaction basic fill of asphalts and gravels ensure maximum life of the road structure.
Motor Grader is also known as Grader or Road grader, it is one of the important Earthmoving equipment is used to create a flat surface during road construction process. Its long blade helps in creating a flat surface during grading process of road construction. It’s generally used for construction and maintenance of gravel road and dirt roads. While building paved roads, it is used to prepare the base course to create a wide flat surface on which asphalt is placed. The machine consists of three axles, engine and cab.
The grader is also consists these works, include, Leveling of soil, Spreading of soil & aggregates etc, Trenching, land grading, moving earth from one place to another, Ditching and various other tasks.
The compactor usually also known as Road roller machine, this road construction equipment plays crucial role in road construction process, it is used for compacting soil, concrete, gravel or asphalt during road construction and foundations process. It’s generally used for compressing the surface.
There are different types of road rollers used for different types of project depending on project requirements, these are; Cylindrical Rollers, Sheepsfoot Rollers, Pneumatic tyred Rollers, Smooth wheeled Rollers, Vibratory Rollers and Grid Rollers.
A Paver is also known by various other names such as asphalt finisher, paver finisher. The job of this road building machine used to lay asphalt on roadways and bridges and various other commercial and residential parking lots for similar work. Paver helps in providing a smooth, consistent surface behind the screed. It is used before roller compactor come into play.
In construction field, Pavement Planer is also known as Cold Planner and asphalt milling machine. This is used for removing asphalt concrete or bituminous pavement from road. Usage of asphalt milling machine help in removing distress from road and provides good driving experience and give longer life to the road.
