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…

The strength and durability of the structure depend on the properties of cement. The fineness of the cement test is conducted to find whether the cement has been grind well or not. What is the fineness of cement? The fineness represents the particle size of cement. It should not be…

The self compaction concrete is the high fluidity concrete. It is used where the location is congested by reinforcement and no possibility of compaction of concrete by mechanically or manually.  We have already discussed the L box test, which is used to determine the workability of Self-compacting concrete. What is…

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…

Usually, the slump test is used to find the workability of fresh concrete at the site. There are other tests used to find concrete workability, such as kelly ball test, Flow table test & Vee Bee Test.  But those tests are not suitable for high fluidity concrete.  The self-compacting concrete…

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…

The development of any particular area depends on the transportation facility of that area. Road transport plays an important role in the country’s infrastructural development.  Likewise, the coarse aggregate used in road structure plays a vital part in its strength.  We have already discussed the classification of aggregates earlier in detail…
