Bitumen Extraction Test [APPARATUS, PROCEDURE, CALCULATION]

In today's video I have explained in detail about the Bitumen Extraction Test used to carry out the binder content in asphalt. Bitumen Extraction test is used to determine the amount of bitumen that is actually used as binding content in asphaltic pavement or asphaltic concrete recently laid at site. The durability, compatibility and resistance from defects like rutting, bleeding, raveling and ageing of flexible asphaltic roads is highly dependent on the amount of the bitumen used for the coating of the filler aggregates used in the asphaltic matrix. So this test is parallel to that of the cylindrical compression test of the actual concrete samples obtained at site before placement of concrete to determine its actual compressive strength to be as per the required mix design. The mix design of asphalt is carried out by series of hit and trial in job mix formula for determination of the optimum binder content. So at site, before final payment to the contractor it must be ensured that the amount of bitumen required by the mix design is actually used at site or not. ============================ Read Complete Article here https://definecivil.com/bitumen-extraction-test/ * Visit our Blog https://www.iamcivilengineer.com https://definecivil.com * Subscribe to our Channel https://www.youtube.com/c/saadiqbalengr * follow us on twitter https://www.twitter.com/iamcivilengg
