  • Aggregate Crushing Value Test -Determine Aggregate

    May 05, 2010· Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions. Aggregate crushing value is a numerical index of the strength of the aggregate Aggregate Crushing Value Test Determine Aggregate,May 17, 2019· 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

  • DETERMINATION OF AGGREGATE CRUSHING VALUE

    The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Crushing value is a measure of the strength of the aggregate. The aggregates should therefore have minimum crushing value. 3.Standard of Crushing Value of Coarse Aggregates for,And, in Chinese technical specifications of asphalt pavement construction, the criterion for crushing value of coarse aggregate in PA mixture is the same as that in AC mixtures, no greater than 26%. So, the state of contact stress between coarse aggregates in PA-13

  • Pavement materials: Aggregates

    The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load. The test consists of subjecting the specimen of aggregate in standard mould to a compression test under standard load conditions (Figure 1). Dry aggregates passing through 12.5 mm sieves and retained 10 mm sieves are filled5 Aggregate Specifications and Requirements,Specifications and the current Supplemental Specifications. The specifications for aggregates are detailed in Section 904 and other sections for the various types of construction. These specifications are to be followed when inspecting aggregates. There are two general types of requirements for aggregate: quality and gradation.

  • Aggregate Impact Value Test, Procedure, Result & Standards

    Aggregate impact value is the ratio of the weight of the fraction passing through 2.36 mm (weight W2) by the total weight of the sample (weight W1 + W2). Aggregate Impact Value = (W2/ (W1+W2)) * 100 = 80 gm 300 gm = 26.67 (Impact Value) Where, W1= Weight of AGGREGATE TOUGHNESS/ ABRASION RESISTANCE AND ,Bullas and West [4] reported the aggregate impact value did not, but the aggregate crushing value did separate suitable and unsuitable aggregate for bitumen macadam roadbase.
