Toughness is the property of a material to resist impact. The most common type is known as sickle cell anaemia. Due to traffic loads the road stone are subjected to the pounding action of impact and there is possibility of breaking into smaller pieces. According to BS-1241, a flakiness index should First, fill the sample aggregate with one-third of the cylindrical measure in three layers Each layer should be tamped 25times freely. All Rights Reserved. Water absorption shall not be more than 2% per unit by weight. The intent of dividing the sample into factions is to find the individual flakiness index corresponding to a particular size range.

Laboratory Purpose The Aggregate and Petrographic Laboratory (APL) at the Turner-Fairbank Highway Research Center (TFHRC) provides facilities for the evaluation, preparation, and testing of aggregate sources, products, and samples for use in concrete, asphalt mixtures, and granular base course applications. ductility of a material that is determined by a tensiontest. Procedure of Shape Tests on Coarse Aggregates Sieve the sample through the IS sieves (as specified in the table). A sieve analysis, or gradation test determines the distribution of aggregate particles by size within a given sample. 2. The shape of the aggregate particles is determined by the percentages of flabby and elongated particles contained in it. Both Flakiness index Elongation Index tests The aggregate should therefore be tough Aggregates are very important component of concrete, so the quality really matters when it comes to aggregates. To separate the elongated materials, gauge each fraction for length on a length gauge. Sample Mould weight and sample weight (W2) 2851 2829. 8.0 Conclusions The value that we get from this test is 15.1% for flakiness and not exceeds 20% the JKR requirement.
