The strength of coarse aggregates is assessed by aggregates crushing test. The aggregate crushing value provider. a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, aggregate possessing low aggregate crushing value.
Why crushing value test for coarse aggregate is important Below is some information about the products equipment, if you puzzle about the pricethe factorythe model and the photo of YEC production, or want to know about.
Read MoreMar 30, 2020 The aggregate crushing value test evaluates the ability of the aggregates used in road or pavement construction to withstand the stresses induced by moving vehicles in the form of crushing. With this, the aggregates should also provide sufficient resistance to crushing under the roller during construction work and under rigid tyre rims of.

Read MoreMar 28, 2021 Aggregate crushing test values indicates the strength of aggregate and hence it is very significant. Similarly we can say crushing value is the relative measure of resistance of an aggregate under gradually applied compressive loads. Higher crushing strength means lower crushing value.

Read MoreAggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Consists of 150 mm steel cylinder, plunger, base plate, tamping rod 16 x 600 mm and measure 115 x 180 mm deep. Used for aggregate passing 12.7 mm and retained by 9,52 mm sieve.
Read MoreJan 20, 2020 The value of maximum pressure in the crushing test of coarse aggregate should not be a fixed value, 400 kN, for all kinds of asphalt mixtures. According to the results of PFC2D analysis, the contact stress between coarse aggregates in PA-13 mixture is higher than that in AC-13 mixture to reflect the difference of contact stress between coarse.
Read MoreApr 26, 2018 Calculation of aggregate crushing value. The aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS (here 2.36mm sieve) to the total weight of sample expressed in percentage. W1= Weigh of the total aggregates (Wa-We) W2= Weigh of aggregates passing through 2.36mm IS sieve.
Read MoreMay 27, 2020 The crushing value of an aggregate indicates its resistance against crushing under gradually applied compressive loads. The standard aggregate crushing test is made on aggregate passing 12.5mm IS sieve and retained on 10 mm IS sieve. Procedure. About 6.5 Kg material consisting of aggregates passing 12.5mm IS sieve and retained on 10mm sieve is.
Read MoreThe apparatus of the aggregate crushing value test as per IS 2386 (Part IV) – 1963 consists of 1) A 15cm diameter open ended steel cylinder with plunger and base plate, of the general form and dimensions as shown in Fig 1. 2) A straight metal tamping rod.
Read MoreDec 16, 2020 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 compressive load. To achieve a high quality of pavement aggregate possessing low aggregate crushing value should be preferred.
