Procedure of the LA Abrasion Test: Prepared sample is placed in the abrasiontesting machine. A specified number of steel spheres are then placed in the machine and the drum is rotated for 500 revolutions at a speed of 30 33 revolutions per minute (RPM). The material is then separated into material passing the mm (No. 12) sieve and material retained on the mm (No. 12) sieve. Dry ...
Aggregate Crushing Strength Test
· AGGREGATE CRUSHING STRENGTH TEST Theory and Scope: This is one of the major Mechanical properties required in a road stone. The test evaluates the ability of the Aggregates used in road construction to withstand the stresses induced by moving vehicles in the form of crushing. With this the aggregates should also provide sufficient resistance to crushing under the roller during .

LABORATORY MANUAL OF TEST PROCEDURES FEBRUARY 2021
This manual describes the test procedures that are currently in use in the Material Laboratory of the Construction Section. Methods of testing fall into four main groups: 1. Those which follow a national standard (not included in this manual). 2. Those which mainly follow a national standard but have been modified for use in our laboratory (only the modifiions are in this manual). 3. Those ...
Aggregate crushing test
· Aggregate crushing Test procedure. Oven dry the aggregates; Firstly, sieve the aggregate using Indian standard sieves. Then collect the specimen passed through mm and retained on a 10mm sieve. Thus is the test sample of aggregate. Then put the cylinder on the base plate and weight it (W). The aggregate sample should be filled in 3 layers, each layer is subjected to 25 .

Crushing Value Test Of Aggregate
Aggregate Crushing Value Test Procedure. · The aggregate crushing value is an indirect measure of crushing strength of the aggregates. Low aggregate crushing value indies strong aggregates, as the crushed fraction is low. Thus the test can be used to assess the suitability of aggregates with reference to the crushing strength for various types of pavement components. Get .
