As mentioned above, bitumen is used as a binding material in the road construction. Bituminous Material - an overview | ScienceDirect Topics The bitumen content in the emulsion is around 60% and the remaining is water. Primarily, the bituminous materials are extensively used for road construction only. INTODUCTION TO BITUMEN Those materials are mainly used in the flexible roads as stated. Also, we will see bitumen road layers, different bituminous materials, cutback bitumen, grade of bitumen and properties of bitumen. Highway construction requires a lot of energy at different levels: for the production of asphalt and cement destined to pavements and excavating materials, for road maintenance, and by vehicles stuck in congestion due to poorly designed highways. Physical properties of the aggregates must fulfill the following standard test values given below : Asphalt is called a bituminous material because it . How To Calculate Quantity Of Asphalt For Road Construction The materials in which bitumen and asphalt are present are known as Bituminous Materials. In the first stage basic property of bitumen is modified by adding the crumb rubber in 1-4%. Liquid asphalt.
