7 Lab Tests on Aggregates to Make Better

The aggregate crushing value test indicates the strength of aggregate which is the most essential property of coarse aggregate. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. For achieving a high quality of pavement, aggregate of higher crushing strength i.e. low crushing value should be preferred. Lower crushing

NOTE 2 - The standard aggregate crushing test shall be made on aggre a 12.5-mm IS Sieve and retained on a IO-mm IS Sieve. If required, or if tR ate passing e standard size is not available, other sizes up to 25 mm may be tested but owing to the noIlchomo- geneity of aggregates the results will not be comparable with those obtained in the standard (see Note 1 under 2.6). Smaller sizes may also

Aggregate Crushing Value Test – Determine

The ' aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. 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

Pavement materials: Aggregates - Civil

Crushing test One of the model in which pavement material can fail is by crushing under compressive stress. A test is standardized by IS:2386 part-IV and used to determine the crushing strength of aggregates. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load.

Shape Tests for Aggregates 7.3.1 Flakiness index 7.3.1.1 Introduction. Flaky or elongated materials, when used in the construction of a pavement, may cause the pavement to fail due to the preferred orientation that the aggregates take under repeated loading and vibration. It is important that the flakiness and elongation of the aggregate are contained to within permissible levels. 7.3.1.2
