Thanks for your kind visit!
how you doing? Today I am going to post here what I learnt about the highway construction equipment.
As we know that highway construction at field can be broadly classified into two phases:
- Excavation or preparation of sub-grade.
- Pavement layers construction.
In the phase of the excavation or preparation of the sub-grade we need two types of equipment:
- Excavation equipment
- Compaction equipment
- Bull Dosser
- Scraper
- Power Shovel
- Drag-line
- Clam-shells
- Hoe
- Bulldozer

Bulldozer is a versatile equipment because it can be used in undulating ground or level ground, can be used for various building construction projects including pilot road constructions or even in farms.
- Scraper: Scraper is having a blade in its rear part which is used to scrap the earth and then to store it in the bowl. Once the bowl is full the loose earth can be hauled to the deposition site. There is an elevator arrangement for the blade which can elevate or lower the blade according to the need.
- Power Shovel: Power shovel is a power equipment used to dig the earth material at lower depths than the standing elevation. The parts of a power shovel are crawler mounting, cab, boom, shovel and hoist cable.

- Drag-Line: Drag line has a bucket suspended from the book which can be dragged with a drag cable and hoist cable to collect the loose material inside the bucket.

- Hoe: Hoe can be used to excavate relatively stiffer earth from a depth below the standing level of the equipment. This material can excavate all types of earth materials except hard rocks.
