AIM OF THE EXPERIMENT To determine the Flakiness Index of the given sample of course aggregate CODE OF REFERENCE • IS 2386 Part 1 1963 Methods of Test for Aggregates of Concrete Particle Size and Shape Reaffirmed Dec 2016 • ASTM 4791 10 Standard Test Method for Flat Particles Elongated Particles or Flat Elongated Particles in Coarse Aggregates
The effect of flakiness one of the shape characteristics of aggregate on concrete is not an issue sufficiently clarified In addition there are no satisfactorily detailed limitations for
Aggregate testing Tests We Conduct Sampling Bulk density Particle density and water absorption Particle size distribution Proportional calliper flakiness index average least dimension crushed faces and weak particles Aggregate crushing value wet/dry strength variation and los angeles value Degradation Factor
The shape test assesses the flakiness and elongation index ensuring that aggregates do not contain particles detrimental to the mix s stability 6 Bitumen Adhesion Bitumen Adhesion Test on Aggregates After crushing the aggregate is sieved through a sieve and the weight of the material passing through is measured The
In order to achieve this goal the test coarse aggregates underwent aggregate impact value AIV aggregate crushing value ACV flakiness index and specific gravity tests while the coarse
The aggregate morphology is mainly governed by aggregate mineralogy type of rock and crushing operation [8 9 10] For given aggregate type the associated crushing mechanism plays a decisive role in governing morphology of aggregates The crushing of aggregates involves three prime mechanisms namely abrasion cleavage and impact The
Furthermore the aggregate crushing value flakiness index and water absorption factor of and % respectively do not exceed the corresponding values of 30 35 and % respectively provided for in the FMWH 1997 specification Clause 6371 Table VI 13 The aggregates are therefore of the quality required Aggregate Gradation

Several tables of results are included One purpose of the paper is to open a discussion of whether flakiness index values could be raised at par to concrete without disturbing other physical requirements of aggregate against wet mix macadam construction Availability Find a library where document is available
Aggregates are considered the main components of asphalt mixtures in terms of weight volume and flexibility of pavements Countries are looking for alternative materials for use in pavements as

The document summarizes a study that characterized aggregates from four locations KP CS QC NM near major quarries in Kumasi Ghana Engineering tests were performed on the aggregates including specific gravity water absorption aggregate impact value aggregate crushing value ten percent fines value flakiness index elongation index and Los
Flakiness index A and mean flatness factor W/T mean are two concepts that characterize differently aggregate flakiness The flakiness index is a proportion by weight of particles whose thickness is below a standardized d/1 Eloranta J Crushing process planning Aggregate 2001 environment and economy Helsinki vol 1 2001 p 81 5
As aggregate crushing and impact tests require a different set of equipment therefore the motive behind the study is to accurately predict th eir test result s using a simplified test
Nevertheless a higher flakiness index was obtained after the crushing of non flaky particles and a lower one after the crushing of flaky particles The flakiness index for grains below 16 mm after the crushing process was less than 10% which indicates a more favorable result compared to the original feed
A novel model capable of predicting aggregate shape is presented in this paper The particle flakiness model has two parameters the average particle size of the feed and the closed side setting CSS of the common method used for controlling the process flow in a crushing plant is also demonstrated
This document provides information on various tests conducted on pavement materials including aggregate crushing value impact value elongation and flakiness index Los Angeles abrasion soundness and sand equivalent tests It describes the testing procedures and specifications for each test The aggregate crushing value test indicates an
The crushing value of the aggregate determines its a Hardness b Strength c Toughness d Durability View Answer Answer b Explanation The flakiness index for aggregates that are used in the pavement surface dressing should not exceed 25% but in any case combined flakiness and elongation index should never exceed 30%
