From the data obtained and the Aggregate Impact Value Test (AIV) that we have done, it shows that our mean value from all three samples is 24.5%. Based from the Aggregate Impact Standard, for the aggregate impact value of 24.5% which is 20% 30% is satisfactory strong for road surfacing.

AGGREGATE IMPACT VALUE TEST

Aggregate Impact Value (BS 812: Part 3) 1. Objective. To determine the aggregate impact value in the laboratory. 2. Introduction. Impact value of an aggregate is the percentage loss of weight particles passing 2.36mm sieve by the application of load by means of 15 blows of standard hammer and drop, under specified test condition.

Calculate the mean of the two values determined in (a) or (b) of 7.6.6.2 to the nearest whole number. Report the mean as the aggregate impact value, unless the individual results differ by more than 0.15 times the mean value. In this case repeat the test on two further specimens, calculate the median of the four results to the nearest

IMPACT VALUE OF AGGREGATE 1.Objective The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from its resistance to a slow compressive load.

The Procedure of Impact Test on Aggregates: Aggregate impact value (The value of aggregate impact test) = (W1/W2)*100. The value of aggregate impact test should not be more than 45% by weight of aggregates, used for concrete other than wearing surface. An impact value 35% is permissible for the bituminous macadam.

Dec 08, 2017· In this video,we will see the procedure of determining aggregate impact value as per IS 2386 PART4.

aggregate impact value test With Respect to concrete aggregates,toughness is usually considered the resistance of the material to failure by impact.Several attempts to develop a method of test for aggregates impact value have been made.The most successful

The test aims at looking for the forces required to produce 10% of fine values (i.e. weight of fines aggregates/weight of all aggregates = 10%). This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value.

aggregate impact value test With Respect to concrete aggregates,toughness is usually considered the resistance of the material to failure by impact.Several attempts to develop a method of test for aggregates impact value have been made.The most successful

The test sample consists of aggregates passing 12.5mm sieve and retained on 10mm sieve and dried in an oven for four hours at a temperature 100 0 C to 110 0 C and cooled. Test aggregates are filled up to about one-third full in the cylindrical measure and tamped 25 times with rounded end of the tamping rod.

Mar 27, 2020· AGGREGATE IMPACT VALUE TEST AIM: To find Impact value of the given aggregate sample. APPARATUS The apparatus consists of an impact-testing machine, a cylindrical measure, tamping rod, IS sieve, balance, tamping rod and oven. PROCEDURE The test sample consists of aggregates passing 12.5 mm.

TRANSPORTATION ENGINEERING LAB MANUAL 2013 aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load. 3. APPARATUS The apparatus of the aggregate impact value

The aggregate crushing value (ACV) of an aggregate is the mass of material, expressed as a percentage of the test sample. which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN. 2 APPARATUS 2.1 An

Oct 27, 2017· The Impact value of an aggregate is the percentage loss of weight particles passing 2.36mm sieve by the application of load by means of 15 blows of standard hammer and drop, under specified test condition. Measurement of Impact of Jet on Flat Plate Vane and Hemispherical Cup lab report. October 28, 2017

Nov 07, 2012· Sieve Analysis Lab Report Tech Writing Lab Report Dr. Clinton Lanier Written by: Jon Leyba Date Assigned: 10/17/2011 Date Due: 10/24/2011 Introduction: The purpose of his lab is to perform a sieve analysis on a sample of soil collected near the EMRTC facility behind the New Mexico Tech Campus. The soil sample has reddish fines, sand, and gravel.

number. Report the mean as the Aggregate Crushing Value, unless the individual results differ by more than 0.07 times the mean value. In this case repeat the test on two further specimens, calculate the median of the four results to the nearest whole number and report the median as the Aggregate Crushing Value. A data sheet is given as Form 7.7.1.

Feb 08, 2012· Aggregate impact and 1. 10 Aggregate Crushing Value TestINTRODUCTION The principal mechanical properties re~ired in road stones are Q satisfactory resistance to crushingunder the roller during construction and (jjI adequate resistance to surface abrasion under traffic.

The aggregate impact value gives a relative measure of the resistance of an aggregate to “sudden shock or impact”, which in some aggregates differs from its resistance to a slowly applied compressive load. With aggregate of aggregate impact value (AIV) higher than 30 the result may be anomalous.

lab report for aggregate impact value. The aggregate Impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from its resistance to a slowly applied compressive load. With aggregate of aggregate impact value higher than 30 the result may be anomalous.

The Los Angeles test is a measure of degradation of mineral aggregates of standard gradings resulting from a combination of actions including abrasion or attrition, impact, and grinding in a rotating steel drum containing a specified number of steel spheres. The Los Angeles (L.A.) abrasion test is a common test method used to indicate aggregate toughness and abrasion
