crushing value and, when appropriate, the polished stone value and aggregate abrasion value. Sampling and testing should be in accordance with the methods described in British Standard BS 812 (1985, 1989a, 1989b 1990a, 1990b). Specifications for maximum aggregate crushing value (ACV) for surface dressing chippings typically lie in the range 20 ...
To ensure good pavement performance, aggregates must be resistance to crushing under gradually applied compressive load, abrasion effect, sudden shock and also particle shape element. The crushing value gives value of hardness of aggregate when subjected to 400 kN load in accordance to BS 812: Part 3.
BS :1985 was a revision of of BS 8121:1975 and in this edition the specification for the thickness gauge used in the method, and the procedure, have been revised to reflect current practice. The associated test for angularity number given in the 1975 edition of BS 8121 was not included in the 1985 revision because of lack of use.

AGGREGATES Aggregate is a collective term for the mineral materials such as sand, gravel and crushed stone that are used with a binding medium (such as water, bitumen, Portland cement, lime, etc.) to form compound materials (such as asphalt concrete and Portland cement concrete). Aggregates can also be defined as granular materials of mineral [.]

This Appendix outlines the tests and procedures used to describe or evaluate the physical, mechanical and chemical characteristics of natural stone and rock used in construction. The different characteristics required by the uses of stone and rock covered in this book have resulted in a wide range of tests being developed to describe the material and to assess its potential value.
The range of tests carried out on aggregates for construction purposes has been harmonized throughout the world. Some familiar aggregate tests such as Aggregate Crushing Value, Ten Percent Fines Value, Aggregate Impact Value, Flakiness Index, Sieve gradation, Polished Stone Value, Aggregate Abrasion Value, have been retained virtually intact.
Dolerite and syenite were comparatively studied and evaluated for their potential as crushed stone for civil engineering construction. Properties of the rocks tested included specific gravity, moisture absorption, Schmidt hammer rebound, pointload strength, unconfined compressive strength, Los Angeles abrasion, aggregate crushing value, sodium sulphate soundness, and ultrasound velocity.
