these characteristics can be quantitatively evaluated by the aggregate crushing value, which is an index of the aggregates ability to resist breakage in road bases that has been included in
specification :aggregate impact value test apparatus is used for determining the aggregate impact value. the sturdy construction consists of a base and support columns to form rigid framework around the quick release trigger mechanism to ensure an effective free fall. of the hammer during test. the free fall can be adjusted through 380
the apparatus of the aggregate crushing value test as per is: 2386 1963 consists of: diameter open ended steel cylinder with plunger and base plate, of the general form and dimensions as shown in fig straight metal tamping rod
impact and crushing value aggregate crushing value sets. uta-0630 aggregate crushing value set 150 mm bs. uta-0640 aggregate crushing value set mm bs. the aggregate crushing value test set measures how resistant an aggregate is, when being crushed under a gradually applied compressive load.
specification: the aggregate crushing value test set provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. each set consists of steel cylinder, plunger, base plate, cylindrical measure and tamping rod. all parts
calculation of aggregate crushing value. the crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.m and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results.
aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. ten percent fines value used for testing aggregate smaller than mm. comprises: 150 mm or diameter steel
In current chinese technical specification, the crushing value of the coarse aggregate for surface layer of asphalt pavement is no greater than 26% so, the crushing value standard of basalt coarse aggregate used in PA mixture should be increased to not more than 26%1.48 17.6%.
specification the selection of proper aggregate for a given application is essential to attain the desired quality. various characteristics are required to be determined for the selection of appropriate aggregate from the wide range available. aggregate crushing value test apparatus is used for measuring resistance of an aggregate to crushing.
SS specification for methods for sampling and testing of mineral aggregates, sand and fillers determination of aggregate impact value, aggregate crushing value and ten percent fines value. singapore standard, singapore.2. millard, r.s. road building in the tropics.
between aggregate crushing value and ten percent fines aggregate crushing value for some aggregates in nigeria. such a mathematical relationship, usually established through regression modelling on data collected, is useful in saving time and money cost on site through estimating one variable when another is known.
