Aggregate Crushing Value Test Determine Aggregate. Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and the strength of the aggregate used in road construction is expressed by numerical index.

It is important because the constituent aggregate must resist crushing, degradation and disintegration in order to produce a high quality. For this experiment, the LA Abrasion value obtained was 6 % and 9. %. based on the JKR Specifiion, the aggregate for use in bituminous road surfacing is maximum 40%. So, the value that was obtained is ...

Aggregate Water Absorption Test. Water absorption gives an idea of strength of aggregate. Aggregates having more water absorption are more porous in nature and are generally considered unsuitable unless they are found to be acceptable based on strength, impact and hardness tests. Water absorption shall not be more than 2% per unit by weight.
