crushing value, the aggregate impact value should not exceed 45% by weight for aggregates used for concrete other than for wearing surfaces and 30% by weight for concrete for wearing surfaces, such as runways, roads for pavements. Specific gravity, a low specified gravity indicates to high porosity, which results in poor durability and low ...

Aggregate crushing value = (W2 x 100) / (W1-W) W2 =Weight of fraction passing through the appropriate sieve W1-W =Weight of surface dry sample. The mean of two result to nearest whole number is the aggregate crushing value. Result The aggregate crushing value of the given sample= Aggregate Crushing Values for Roads and Pavement Construction

The crushing value indicates the strength of aggregates. The aggregates used for quality pavement should be strong enough to withstand the crushing under roller and traffic loads i.e. Low crushing value. A lower …

The aggregate crushing value test is an important test of aggregates. It gives a numerical index of the strength of the aggregate and it is used for concrete in construction of roads and pavements. The aggregates, have minimum crushing value, are recommended for roads and pavements as it indicates a lower crushed fraction under load and would ...

12. Crushing value of aggregate. Determination of the crushing value of an aggregate is helpful to find the compressive strength of the aggregate, whether it is suitable for the concrete work or not. One of the important properties of aggregates affects the overall strength of the structure. 13. Impact value of aggregate

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 crushing strength or aggregate crushing value of a given road aggregate is found out as per IS-2386 Part- 4. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied …

Aggregate Crushing Value The aggregate crushing value indicates the ability of an aggregate to resist crushing The lower the figure the stronger the aggregate, i.e. the greater its ability to resist crushing The aggregate passing 12.5 mm sieve and retained on 10 mm sieve is selected for standard test Compression testing machine with
