Read MoreThe aggregate crushing value that we obtained from the experiment is about 20.1%. We are satisfied with this value. since it is lower than the ASTM requirement, which is 35%. Hence, we recommend that this type of aggregate is suitable use to construct the highway road and can withstand. heavy traffic load.Aggregate Crushing Value -1 Construction Aggregate,Aggregate Crushing Value{IS: 2386 (Part IV) 1963} Aggregates used in the construction, should be strong enough to resist crushing. If the aggregates are weak, the stability of the structure is likely to be adversely affected. The strength of coarse aggregates is assessed by aggregate crushing test. The aggregate crushing value provides a relative measure of resistance to crushing under

Dec 15, 2017· Aggregate Impact Values and Aggregate Crushing Values are often numerically very similar, and indicate similar aggregate strength properties. Classification of aggregates using Aggregate Impact Value is as given below: Aggregate Impact Value Classification <20%.= Exceptionally Strong 10 20% .=Strong 20-30%. =Satisfactory for road surfacingShape tests of aggregate SlideShare,Jul 27, 2018· Balance 2. Metal gauge 3. IS Sieves 4. Sample of aggregate (a quantity of aggregate shall be taken sufficient to provide a minimum no of 200 pieces od any fraction to be tested.) 8. Theory The elongation index on an aggregate is the percentage by weight of particles whose greatest dimension (length) is greater than 1.8 times their mean dimension.

SUMMARY OF TEST There are two test methods for determining the clay lumps and friable particles in aggregates. There is a method for coarse aggregate and one for fine aggregate. The test methods are similar, but there are differences, so always be sure to follow the correct method for the type of aggregate being tested.Aggregate coarse aggregates, testing & limits,Sep 05, 2018· • 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 and it is used in construction of roads and pavements. 51.

Jan 13, 2011· Aggregate Crushing value depends on the shape of agg also. Angular aggregates have a lower ACV, than Irregular or rounded aggregates.If we cut a core out of the same agg (Say in the quarry) and test for compressive strength, will give a higher MPa value. It can be considered as a concrete cylinder or UCS tested in lab. So it is hard to corelateObjective,Aug 29, 2015· In this experiment that we have carried out,our aggregate impact value (AIV) is 15.82% which is in the range of 10%-20% and it is strong enough for road surfacing. b) Give two experiments for aggregate degradation other than AIV test.
