The aggregate crushing value is a numerical index of the resistance of an aggregate to crushing under a gradually applied compressive load. It is expressed as the percentage by mass of the crushed or finer material obtained when the test sample is subjected to a specified load under standard conditions.Free quote
TRANSPORTATION ENGINEERING LAB MANUAL 2013 1 DEPT. OF CIVIL ENGG., DRONACHARYA GR OUP OF INSTITUTIONS, GREATER.NOIDA Experiment No.1 DETERMINATION OF AGGREGATE CRUSHING VALUE 1. AIM 1 To determine the aggregate crushing value of coarse aggregates 2 To assess suitability of aggregates for use in different types of road pavement 2.
This percentage is known as a crushing value of aggregate. This percentage should not exceed 30 of the total weight of aggregate taken for the test. The aggregate crushing value test result should not be more than 30 for the concrete used for roads and pavements and, in case of other structures it may be permitted up to 45.
Based on the classification, rock materials with grinding energy gt10 kWht could be suitable for aggregate production and usable for civil construction purposes. Keywords- Aggregate, Aggregate impact value, Aggregate crushing value, Comminution, Grinding energy.

Aggregate crushing value civil engineering. aggregate crushing value this test helps to determine the aggregate crushing value of coarse aggregates as per is 2386 part iv 1963. the apparatus used is cylindrical measure and plunger, compression testing machine, is sieves of.
Aggregate Crushing Value and Its Test Procedure One of the test in which concrete material can fail is due to crushing under compressive stress. Aggregate crushing test is standardized by IS 2386 part-IV and used to verify the crushing strength of aggregates. The aggregates should be oven dried, which can passes through 12.5mm and retained on.

Experiment No. 4 Determination of the aggregate impact value of different coarse aggregate samples. BS 812 Scope amp significance Aggregate Impact Value The aggregate impact value gives a relative measure of the toughness or the resistance of aggregate sudden shock or impact is not proportional to the resistance to a slowly applied compressive load.

A Superpave mix with a 12.5-mm 12-in. nominal maximum aggregate size gradation was produced with each aggregate source using the same PG 64-22 asphalt binder. The mixtures were produced to investigate the impact of aggregate properties on their volumetric properties as well as the tensile strength from the indirect tension tests and rutting.
