Bitumen is a visco elastic material. that is at room temperature it act as a semi solid. in high temperatures over 60C it acts as a Newtonian fluid or low viscosity liquid. Penetration and viscosity are the main two properties checked to categories bitumen. on the other hand flash point,fire point,solubility, ductility and softening point of the bitumen are also checked.

How much Bitumen is used in 1km of road surface?
The exact make-up of a road will depend on several variable factors such as the weight and volume of traffic it has been designed to carry, local climatic conditions and the availability of mineral aggregates. In most cases, bitumen will be needed for its properties of waterproofing and durability and as the cheapest adhesive generally available. A minor secondary road may use bitumen only for its top two courses, at the rate of 7 tonnes per kilometre. A highway engineer may call for three asphalt courses, with tack coats in between, because of asphalt's superior load bearing properties. In this case, bitumen consumption can amount to 1,000 tonnes per kilometre. The bitumen percentage in asphalt is usually between 4-8%.
What is the density of bitumen 60 70 for road work?
The density(sp. Gravity) of Bitumen Grade 60/70 has Near about 1.01-1.08 gm/cc. and the final value will conform after Testing.
What is pitch in a roof?
Pitch is a bitumen or it can mean the slope of the roof for example 1/8" per foot fall

What and define the properties?
The answer will depend on the properties of what!
Is bitumen magnetic?
No, bitumen is not magnetic as it does not contain any magnetic properties. It is a natural substance derived from crude oil and is primarily composed of hydrocarbons.
What is the density of bitumen at different temperature ranges?
The density of bitumen can vary depending on the temperature. At 25°C, the density of bitumen is around 1,000 kg/m^3. As the temperature decreases, the density increases due to the bitumen becoming more viscous. Conversely, as the temperature increases, the density decreases as the bitumen becomes less viscous.
What is the difference between oil rectified bitumen and oxidised bitumen?
Bitumen whose rhelogical properties have been modified by reaction with air at elevated temperatures. This material is referred to as blown bitumen Oxidised while Air rectified bitumens are used in paving applications as well as roofing applications for some industrial applications.For more info: http://www.roadstarbitumen.com
What are physical properties of bitumen?
Bitumen is a black or dark-colored solid or semi-solid material that is sticky, water-resistant, and highly viscous. It is insoluble in water but soluble in carbon disulfide and carbon tetrachloride. Bitumen has a high melting point and can soften when heated.
What has the author Evert Alan Mulder written?
Evert Alan Mulder has written: 'Interfacial properties of bitumen emulsions'
Why water destroy bitumen roads?
Water can penetrate the small cracks in bitumen roads and weaken the structure by eroding the base layers, leading to potholes and pavement failure. Additionally, water can cause the bitumen to soften and lose its binding properties, reducing the road's durability and strength over time.
Effect of aging on bitumen?
Aging of bitumen, common in road construction, affects its properties like stiffness, viscosity, and durability. Over time, bitumen can harden and become more brittle due to oxidation and volatilization of its lighter components. This can lead to cracks and reduced performance in road surfaces. Regular maintenance and treatments can help mitigate the effects of aging on bitumen.
How do you get soft bitumen to set at room temperature?
To get soft bitumen to set at room temperature, you can mix it with materials such as crushed rocks, sand, or polymers to create an asphalt mixture. This mixture will then harden as the bitumen cools and solidifies, making it suitable for road construction or repair.
