Procedure The aggregate sample: The material for the standard test consists of aggregates sized 10.0 mm to 12.5 mm.The aggregates must be in a surface dry condition before testing. The aggregates may be dried by heating at 100 oC – 110 o C for not more than 4 hours and cooled to room temperature before testing, if necessary.

Physical Properties of Aggregates 54 • Aggregate tests – Consensus properties - required – Source properties - optional • Aggregate criteria – Based on aggregate blend – Based on traffic and depth into pavement • Design aggregate structure – 0.45 power chart – Controls points and restricted zone Superpave Aggregate Tests

The aggregates are used for the surface course of the highway pavements and they are subjected to wearing due to movement of traffic. (L os Angeles abrasion test ASTM c131). When vehicles travel on the road, the soil particles present between the pneumatic tyres of vehicle and road surface creates the abrasion effect on aggregates.

In this video, we will see the procedure of determining aggregate impact value as per IS 2386 PART4.

Procedure of Aggregate Impact value test. The test sample: normally aggregates sized 10.0 mm to 12.5 mm. the aggregates should be dried by heating at 100-110 0C for a period of 4 hours and cooled. Sieve the material through 12.5mm and 10.0 mm IS sieves. The aggregates passing through 12.5 mm sieve comprises the test material.

The strength of coarse aggregates is assessed by aggregates impact test. The aggregate impact value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, lower aggregate impact value should be preferred. Toughness is the property of a material to resist impact.

A sieve analysis or gradation test determines the distribution of aggregate particles by size within a given sample. This information can then be used to determine compliance with design and production requirements. Data can also be used to better understand the relationship between aggregates or blends and to predict trends during production.

Impact test The aggregate impact test is carried out to evaluate the resistance to impact of aggregates. Aggregates passing 12.5 mm sieve and retained on 10 mm sieve is filled in a cylindrical steel cup of internal dia 10.2 mm and depth 5 cm which is attached to a metal base of impact testing machine.

Aggregate Durability Index. This test, specified in AASHTO T 210, measures the relative resistance of an aggregate to produce detrimental clay-like fines when subjected to mechanical methods of degradation (AASHTO, 2000b [4]).It is not widely used; its chief use has been by western states to identify weathered basalt containing interstitial montmorillonite, which will not maintain strength ...

Classification of Aggregates Based on Size Aggregates are available in nature in different sizes. The size of aggregate used may be related to the mix proportions, type of work etc. the size distribution of aggregates is called grading of aggregates. Following are the classification of aggregates based on size: Aggregates are classified into 2 types according to size
