Asphalt, also known as bitumen (UK: / ˈ b ɪ tj ʊ m ɪ n /, US: / b ɪ ˈ tj uː m ə n, b aɪ-/), is a sticky, black, highly viscous liquid or semi-solid form of petroleum.It may be found in natural deposits or may be a refined product, and is classed as a pitch.Before the 20th century, the term asphaltum was also used. The word is derived from the Ancient Greek ἄσφαλτος ásphaltos.
Road Construction – Tests on Bitumen Materials: Bitumen is a black, sticky, viscous liquid or semi-solid material derived from crude oil. It is generally found in natural organic deposits or may be a refined petroleum product. Bitumen is the essential road construction materials for flexible pavement.
Bitumen Lab. MTRD_admin T21:03:45+03:00. Bitumen is widely used in road construction. It is usually available in dark colours ranging from brown to black. The main purpose of bitumen in road construction is to strongly bind and hold the other pavement components together and provide a smooth and levelled surface for the moving vehicles.

This system may be considered as the first scientific system of grading of bitumen since, previous to it, the hardness of bitumen was judged by chewing. 10.1.1American Context : American Society for Testing and Materials (ASTM) Committee D04 on road and paving materials adopted the grading of bitumen by penetration testing at 250C after 1910.
Road construction materials for bridges, overpasses, and similar structures also include materials like steel reinforcing beams and similar supplies to create a stable structure that can withstand high weights. Structural steel, concrete, and other materials may be used to create the supports, with an asphalt roadbed to allow cars to pass.
The highest amount of bitumen consumption in the world is in road construction and 90% of the total bitumen produced in the world is used in road construction. Bitumen-made asphalt today provides very smooth and safe roads and highways for light and heavy vehicles and quality runways for landing and take-off of aircraft and even very good rail ...
…asphalt is sometimes referred to as a flexible pavement. This is due to its ability to largely resist the stress imposed by slight settlements of the subgrade without cracking. …asphalt is the predominant material used for road construction and maintaining the road network in Europe?
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 …
Partially replacement of waste plastics in bituminous mixes as road construction material. To minimize the cost of bitumen spend for road construction To compare the stability of conventional bitumen mix with plastic modified bitumen mix. To identify the optimum percent of waste plastic to be added in the hot mix asphalt.
The thrust of this study is to generate scientific data which will form basis for using plastic modified bitumen in the construction and repair of roads in Ghana, as well as provide scientific data on the alternative recycling options for managing plastic waste. 2.
