In the past several attempts have been made to develop a relationship between the compaction characteristics and the CBR of different groups of soil. Large scale road constructions are taking place over the length and breadth of India due to adoption of various intensified activities in road construction in India like PMGSY, etc. The Flakiness Index is the total weight of the material passing the various thickness gauges or sieves, expressed as a percentage of the total weight of the sample gauged. it. And then, these two aggregate and 0-5mm aggregate were mixed with various ratio. Both Flakiness and Elongation tests are not applicable to sizes smaller then 6.3mm i.e. avoided or are limited to about 15 % by weight of the total aggregate. The flakiness index of aggregates is the percentages by weight of particles whose least dimension (thickness) is less than 3/5 th (0.6) of their mean dimension. Then the flakiness index is calculated as the total weight of material passed through various thickness gauges, expressed as a percentage of total weight of the sample gauged. PDF | Self-compacting concrete (SCC) is defined as concrete that can be placed normally and will flow under its own weight while maintaining its. There are various types of PAAS-private PAAS and public PAAS. These are the materials of which the thickness is small as compared to the other two dimensions. Aggregate impact value test also gives an indirect indication of the strength characteristics of aggregate Aggregate impact value of a sample also depends on the shape factors such as flakiness index and elongation index of the aggregates It has been found that for majority of aggregates the aggregate crushing value and aggregate impact .

INTRODUCTION: Road transport is one of the most common mode of transport. eEF2 allows the ribosome to move down the mRNA one codon at a time by acting a translocase (1). The gauge length used shall This test is carried out to determine the flakiness index of aggregates. Sorry, preview is currently unavailable. These two types of plastic were seen to be satisfactory in improving the properties of flexible pavements. Open navigation menu. CONTENTS. One of the most important property of aggregates is the resistance to weathering action or soundness .The stone aggregates should retain the strength characteristics and should not disintegrate under adverse weather conditions including alternate dry and wet/freeze-thaw cycles or in other words the aggregates should have enough durability or resistance to weathering action. Flakiness & Elongation Index Test Gauges Thickness Gauge (Flakiness Index BS), comprising 4.9x30 - 7.2x40 - 10.2x50 - 14.4x60 - 19.7x80 - 26.3x90 - 33.9x100 mm slot dimensions Flakiness (Thickness) Gauge Used for Determination of flakiness index of coarse aggregates. = (526/1150) X 100. Elongation index is a aggregate that have length more than 1.8 sieve size. The cumulative percentages passing each sieve are reported in numerical form or in graphical form. The flakiness index of an aggregate sample is found by separating the flaky aggregates by sieving. to determine the elongation index of the given aggregates. Generally, flat and elongated particles are grading-particle size distribution expressed as the percentages by mass passing a specified set of sieves. Reaffirmed- Dec 2016, Table 3 : Recordings for Elongation Index. Length Gauge have length equal to 1.8 times the mean dimension of the aggregate. NDT Test-(compressive strength of concrete & ultrasonicpulse velocity). The total amount passing the gauge shall be weighed to an accuracy of at least 0.1 percent of the weight of the test sample. pieces of any fraction to be tested. In such cases if the estimation of the soundness value could be developed on the basis of some tests which are quick to perform, less time consuming and cheap, then the process will help the constructors enormously. Both flakiness and Elongation tests are not applicable to sizes smaller than 6.3mm (1/4'' sieve). This process is controlled by eEF1 which catalyzes the delivery of aa- tRNA (1) to the site of elongation. The Flakiness Index is the total weight of the material passing the various thickness Test Result Aggregator LoginAsk is here to help you access Test Result Aggregator quickly and handle each specific case you encounter. Flakiness index and elongation index are two important types of indices useful in determining the concentration of a given sample by means of the particles that are present in the sample. thickness) is less than three-fifths of its mean dimension. Weighing balance 4. This document was uploaded by user and they confirmed that they have the permission to share The geometric characteristics conducted on the aggregates were flakiness index, elongation index and aggregate crushing value. Each fraction is gauged in turn for thickness on the metal gauge. 2 OBJECTIVE. <> stream Characteristics of PAAS are mainly used to test, implement, develop, and maintain applications. <> International Journal of Trend in Scientific Research and Development - IJTSRD, Mohd Nissar, IJIRAE - International Journal of Innovative Research in Advanced Engineering, IJIRST - International Journal for Innovative Research in Science and Technology, World Journal of Innovative Research (WJIR), Highway and Transportation Engineering Lab Manual, ANALYSIS AND EXECUTION OF ROAD WORK ON NH-5 MAIN PROJECT REPORT, TRANSPORTATION ENGINEERING LAB MANUAL 2013 DETERMINATION OF AGGREGATE CRUSHING VALUE, PAVEMENT MATERIALS AND CONSTRUCTION 10CV763, Utilization of Different waste Materials in Flexible Pavements, Road Construction Materials Basic Knowledge and Test Procedures, Pavement materials: Aggregates 22.1 Overview, ANALYSING THE PERFORMANCE OF HIGHWAY CONSTRUCTION MATERIALS ABSTRACT, EXPERIMENTAL STUDY ON THE USE OF RECLAIMED ASPHALT PAVEMENT AS BASE COURSE MATERIALS THROUGH BLENDING WITH CRUSHED STONE AGGREGATES SJIF Impact Factor: 5.218 *Corresponding Author, CONCRETE TECHNOLOGY LABORATORY GUDLAVALLERU ENGINEERING COLLEGE, Directorate Of Technical Education Government of Karnataka Department of Technical Education Board of Technical Examinations, Bengaluru Course Title: SOIL & MATERIAL TESTING LAB, Effect of Steel Fibre Reinforcement on Early Strength of Concrete, International Journal of Trend in Scientific Research and Development - IJTSRD, Effect of Shape of Aggregate on Pavement Quality Concrete, Sabarmati River Front Development Corporation Limited, Experimental Study on Partial Replacement of Fine Aggregate by Crumb Rubber, National Rural Roads Development Agency Quality Assurance Quality Assurance Handbook for Rural Roads Handbook for Rural Roads Quality Management System and Quality Control Requirements Quality Management System and Quality Control Requirements, IJIRAE:: Investigating Geometric Characteristics of Cement Concrete Materials, Modeling of Soundness Property-Coarse Aggregates, SUMMER INTERNSHIP REPORT (7/5/2012 - 24/6/2012, OPTIMUM BITUMEN CONTENT FOR BITUMINIOUS CONCRETE AN ALTERNATIVE APPROACH FOR ESTIMATION, Durability Tests and Evaluation of Engineering-Geological Rock Materials within Some Locations at Southern Part of Lower Benue Trough as Construction Aggregates in Ebonyi State, Nigeria, THE FEDERAL DEMOCRATIC REPUBLIC OF ETHIOPIAN ROADS AUTHORITY 2013 PAVEMENT DESIGN MANUAL VOLUME I FLEXIBLE PAVEMENTS, Government of Nepal Ministry of Physical Infrastructure and Transport Department of Roads STANDARD SPECIFICATIONS FOR ROAD AND BRIDGE WORKS, Building+Materials +3rd+Edition+by S.+K.+Duggal, Government of India Ministry of Housing & Urban Poverty Alleviation RAY Quality Assurance Manual 2014 RAJIV AWAS YOJANA RAJIV AWAS YOJANA (RAY) Quality Assurance Manual 2014, NPTEL Introduction to Transportation Planning, SUITABILITY OF SULFUR AS MODIFIER IN BITUMEN FOR ROAD CONSTRUCTION, DETAILED PROJECT REPORT (DPR) of rural road, Laboratory Investigation on the Effects of Flaky Aggregates on Dynamic Creep and Resilient Modulus of Asphalt Mixtures, DEVELOPING APPROPRIATE ROADBASE FOR BANGLADESH PAVEMENTS. It was found among other findings that aggregate characteristics such as; shape, texture and grading contribute significantly to the performance of fresh portland cement concrete. Hence we offer thickness gauge and length gauge to check flakiness and elongation index of the aggregate respectively. The aggregate to be classified is separated into seven sieve fractions from 6,3 to 63 mm. This utilization of wastes is eco-friendly and we can reduce the cost of bitumen being a petroleum product is costly. Two types of plastic were taken thermoplastics and thermoset having their relationship with the heat i.e. The flakiness & elongation index test is connected as thickness gauge and length gauge respectively.
