Tanking of basements: Bitumen is the usual choice for waterproofing of Basements like Asphalt. Preservation of stones: These materials are used for preservation of stonework from attack by salts and other substances present in the ground and atmosphere. Pavements: Largely used for the construction of roads, runways, taxiways, etc.
Bituminous Materials Bituminous material, or bitumen in the form of asphalt, is one of the major highway construction materials used. Asphalt is normally a residue product from the distillation of crude oil and, as refined, is a heavy, viscous material that is semisolid at normal atmospheric temperatures. By controlled processing or blending ...
A road surface (British English), or pavement (American English), is the durable surface material laid down on an area intended to sustain vehicular or foot traffic, such as a road or walkway.In the past, gravel road surfaces, cobblestone and granite setts were extensively used, but these have mostly been replaced by asphalt or concrete laid on a compacted base course.
In cutback bitumen suitable solvent is used to lower the viscosity of the bitumen. From the environmental point of view also cutback bitumen is preferred. The solvent from the bituminous material will evaporate and the bitumen will bind the aggregate. Cutback bitumen is used for cold weather bituminous road construction …

Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and tarmac, bitumen macadam, or rolled asphalt in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, and the core of embankment dams. Asphalt mixtures have been used in pavement construction since the beginning of the twentieth …
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.
Bitumen is an essential component of any pavement and is used widely throughout the world. It can be termed as the building block of the pavements without which all the pavement materials would behave independently and thus will be deemed useless. Almost ninety percent of bitumen is used in road construction. It is usually available in dark colors ranging from brown
Asphalt Paving Materials. Vulcan is a leading producer of asphalt paving mixtures, consisting of construction aggregates, asphalt binder, additives and modifiers. Asphalt was first used in this country just after the Civil War. Today, it is the paving surface for approximately 94% of …
This material is petroleum in a viscous liquid or semi-solid form. When it is used for pavements and road construction it comes in the form of a composite material, asphalt concrete. Asphalt concrete is about 70% asphalt and 30% aggregate particles. Asphalt is one of the most commonly used materials for road construction for a number of reasons.
The objectives of this program can be summarized in the following main points: Enhancing the skills of road construction engineers in their field. Introduction to road construction materials. Determination of engineering properties of road materials. Quality control and quality assurance in road construction.

An ambitious road construction plan is underway in India, which primarily involves bituminous pavements. At the present time, Ministry of Road Transport & Highways (MORTH) Specification for Road and Bridge Works, 2001 Edition is used for construction of all roads including national highways.
The term bituminous materials is generally used to denote substances in which bitumen is present or from which it can be derived. Bitumen is defined as an amorphous, black or dark-colored, (solid, semi-solid, or viscous) cementitious substance, composed principally of high molecular weight hydrocarbons, and soluble in carbon disulfide. This article presents the
Bitumen, asphalt. A heavy fraction from oil distillation. In North America, this material is commonly known as "asphalt cement," or "asphalt.". Elsewhere, "asphalt" is the term used for a mixture of small stones, sand, filler, and bitumen, which is used as a road paving or roofing material.
Mary McMahon Steel beams may be used in bridge construction. One of the most popular road construction materials is asphalt, followed by concrete, but roads can also be made from brick, gravel, and other materials.Material selection involves choosing the best option for the given conditions, considering traffic patterns, weather, cost, and noise issues.
