The bitumen and tar are used as a binding agent. It is mixed with the aggregates in construction of roads. They are easily blendable when the aggregates are in dry condition. In case of water presence in bitumen mixture, it will affect the bitumen bonding with the aggregates and shall…

The bitumen is a by-product material of petroleum. It is mainly used in construction activities.  It is used primarily in highway construction. Throughout the lifetime of the road, it exposes to hot climatic conditions and heavy traffic load. To ensure quality and strength, bitumen is subjected to various tests. The…

The quality and strength of bitumen have been determined by the penetration test, flash and fire point test, and softening point test. Now the bitumen extraction test is conducted to find the quantity of bitumen used in bituminous concrete in percentage. What is a Bitumen Extraction Test? The test used…

Bitumen is a by-product of crude oil which has strong adhesive and waterproofing properties. It is involved in many tests to determine its grade and durability.  The penetration test is performed to determine the penetrate value of the bitumen and a softening point test is conducted to determine the viscosity…

The crushed sand is artificial sand which is manufactured by crushing granite stone. It is manufactured artificially, so it is also called M sand or manufactured sand. Difference between crushed sand and river sand Parameters Crushed Sand River Sand Cost The crushed sand is manufactured from available rock stone, and…

The aggregates are classified based on shape, size, density, Geographical Origin. We have discussed the same in detail on the classification of aggregates. Based on their transportation and origin, they are classified as transported soil and residual soil. What is transported soil and residual soil? The deposited soil transported from…

You are all aware that aggregates occupy 70 to 80% of the total volume of concrete.  The fine aggregates are used as filler material & the coarse aggregate are used in concrete to increase the compressive strength of the concrete.  The size of the aggregates influences the bondage of the…

All of you are aware that the bitumen is a by-product material of petroleum which is mainly used for road construction work & other miscellaneous work. We are going to discuss the test, which is useful to grade the bitumen-based on its consistency. What is the penetration test of bitumen?…

Earlier, we had discussed the penetration test of bitumen to find out the consistency or hardness, grade the bitumen for the construction work. In this, we are going to test the softening point of bitumen. The softening point test used to determine the melting point in which the bitumen reaches…

Every material usage by the urban population affects nature and makes scarcity.  For example, take petroleum. It takes quite a long time to get crude oil likely 50 million years. In just 50 years we are going to run out of it. So humanity is moving to another energy resource.…
