This document describes the aggregate crushing value test procedure which is used to determine the resistance of aggregate samples to crushing under gradually applied loads. The test involves applying a 40 tonne load to aggregate samples contained in a metal cylinder and measuring the percentage …
The crushing value of aggregates is rather insensitive to variation in strength of weaker aggregates. For this reason, a simple test known as 10 percent fine value is introduced. When the aggregates crushing value become 30% or higher, the results are likely to be inaccurate. Aggregate Crushing Load (Source: IS 2386(Part 4):1963) The aggregates ...
The aggregate crushing value of the sample was calculated to be 20.4%, indicating the aggregates are of lower quality but still suitable for uses that do not involve heavy traffic loads. Issues with the experiment included potential errors from an open sample mound and limitations of the crushing machine for real-world applications.
Aggregates are tested for strength, toughness, hardness, shape, and water absorption. In order to decide the suitability of the aggregate for use in pavement construction, following tests are carried out: One of the model in …
Aggregate Crushing Value (ACV) – this is the measurement of the resistance of aggregate to crushing by compressive force. A test specimen (10-14mm) is compressed (up to 400 kN) and the proportion of material passing 2.36 mm is the ACV (mean value of two tests). The higher the value the weaker the aggregate.
Objective. To estimate the aggregate impact value of given sample. IS Standards used:IS: 2386(Part-4)-1963 Need and scope:The 'Aggregate Impact Value' gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from its resistance to a slow compressive load.The property of a material to resist …

Determine the aggregate crushing value of coarse aggregate. Assess suitability of coarse aggregates for use in different types of road. Theory: The " aggregate crushing value " give a relative measure of the resistance of an aggregate to …
Experiment No. 4: Determination of the aggregate impact value of different coarse aggregate samples. (BS 812) Scope & significance: Aggregate Impact Value The aggregate impact value gives a relative measure of the toughness or the resistance of aggregate sudden shock or impact is not proportional to the resistance to a slowly applied compressive load.
The document describes an experiment to determine the aggregate impact value of a given specimen through a standardized test procedure. Three samples were tested by subjecting aggregates retained between 10mm and 12.5mm sieves to …
The Aggregate Crushing Value (ACV) test conducted on coarse aggregates provides a relative measure of their resistance to crushing under a gradually applied compressive load. Expressed as a percentage by weight, …
Six aggregates sampled from different sources were subjected to various aggregate tests, including the Los Angeles abrasion, micro-Deval, soundness magnesium, and acid insoluble tests. A Superpave mix with a 12.5-mm (1/2-in.) nominal maximum aggregate size gradation was produced with each aggregate source using the same PG 64-22 asphalt binder.
