Jan 22, 2017 Road construction equipment are found in a wide variety ranging from the very heavy equipment to portable and lighter equipment. These modern and high construction equipment make the construction job easier and quicker. Also the work done my heavy machinery is of good quality, this is the reason that we find a wide variety of equipment at every construction site.
Asphalt Mixing Plant. Asphalt Mixing Plant is another important road construction equipment. If the project is a large one, then the asphalt mixing plant is set on the road construction site. In this process, the concrete asphalt including other materials including macadam and coated roadstone are mixed together in correct proportion.
Apr 05, 2014 Equipment Used for Bituminous Pavement Construction. Boilers: Boilers are used to soften the bitumen by heating it to certain temperature for its easy application. Sprayer/Distributor: Sprayers are required for spreading/distributing the bitumen on the pavement. If the bitumen is applied with pressure, they are known as pressure distributors.

All flexible pavement courses, except seal coats, are placed loose by means of spreading and leveling equipment and then compacted with compaction equipment. The typical sections or other plan details specify the width and thickness of the individual courses. For granular subbase
Aug 04, 2021 Requirements of highway pavement. The primary function of a pavement is to transmit loads to the sub-base and underlying soil. Modern flexible pavements contain sand and gravel or crushed stone compacted with a binder of bituminous material, such as asphalt, tar, or asphaltic oil. Such a pavement has enough plasticity to absorb shock.
Highway Pavement: Layers, Functions, Types, Defects, Rigid and Flexible Pavements! Pavement design, in general, consists of determining the thickness of the pavement or of the several layers of which it is composed in order to resist the wheel loads of …

This chapter provides a general overview of the equipment and procedures involved in the construction flexible pavements. The equipment includes hot-mix plant operations, trucks, placement equipment, and compaction equipment. Construction procedures such as …
The type of flexible pavement that consists of a directly placed bituminous layer over the sub-grade layer is known as full-depth asphalt pavement. Such a type of flexible pavement can withstand the considerable intensity of stresses and is usually preferred in areas where local construction materials are not available.
