Procedure of Aggregate Impact value test. The test sample: normally aggregates sized 10.0 mm to 12.5 mm. the aggregates should

The average value of the two samples is the Impact Value of Aggregate. Lab Test Report Format. SI: Description: Sample 1 in grams: Sample 2 in grams: 1: Weight of

Now, take a bowl and measure its weight (X). Put the passed dust of aggregate through 2.36 sieve into a bowl. Take the weight of the bowl

The aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load.

The aggregate impact value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, lower

AIV REPORT aggregate impact value introduction aggregates used in road construction, should be strong enough to resist crushing under traffic wheel loads if the To

To determine the aggregate impact value. Apparatus Required. 1. An impact testing machine weighing between 45kgs to 60 kgs with a metal base. 2. A

Aggregate Impact Test Procedure for Determining AIV as Per IS 2386 Part4. The Aggregate impact test is used to determine the aggregate impact value (AIV), which provides a relative measure of the resistance

The ratio of aggregate which passes through the sieve to the total weight of sample in each test in terms of percentage is the impact value of aggregate. Now we

Now, take a bowl and measure its weight (X). Put the passed dust of aggregate through 2.36 sieve into a bowl. Take the weight of the bowl again with the aggregate sample dust (Y). Calculate the weight of passed dust,

Aggregate Impact Test Procedure for Determining AIV as Per IS 2386 Part4. The Aggregate impact test is used to determine the aggregate impact value (AIV), which provides a relative measure of the resistance

their disintegration due to impact. This characteristic is measured by impact value test. The 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 test as per IS: 2386 (Part IV)

2.3 Aggregate Impact Value (AIV) Aggregate Impact Value was obtained in accordance with the specifications in [4]. The material for the standard test consists of aggregate passing a 12.5 mm sieve and retained on a 10.0 mm sieve. The sample was surface dried for a period about 4 hours at a temperature not exceeding 110oC. The

This property is measured by aggregate impact value test. So that aggregate impact value test is used to determine the relative measure of the resistance of aggregate to sudden shock or impact, which in some aggregate differs from its resistance to a slowly applies compressive load.

Abstract. The Charpy impact test, just like any impact testing method, determines the toughness of materials by measuring the amount of energy absorbed by a specimen as it fractures while being

tests are discussed in this report: 1. Unconfined freezethaw test for coarse aggregate (MTO LS614), 2. MicroDeval abrasion test (BNQ 2560070/82), 3. Aggregate impact vuluc test (BS 812), 4. Polished stone value test (BS 812), and 5. Aggregate abrasion value test (BS 812). The evaluation of the conventional and the alternative tests

The abrasion Test measures aggregate toughness and abrasion resistance such as crushing, degradation and disintegration. This test is suggested by AASHTO T 96 or ASTM C 131: Resistance to Degradation of SmallSize Coarse Aggregate by Abrasion and Impact in Los Angeles Machine. The aggregates are used for the surface course of the

The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results. The crushing value of aggregate = (W2/W1) x 100. Lab Report

Aggregate Water Absorption Test. Water absorption gives an idea of strength of aggregate. Aggregates having more water absorption are more porous in nature and are generally considered unsuitable unless they are

Aggregate Impact Value: BSI BS 812112 (1990c) Aggregate Crushing Value: AS 1141.21 (1997) BSI BS 812110 (1990b) MicroDeval Abrasion: AASHTO TP 58 (1999) The soil compaction procedure was originally developed by Ralph Roscoe Proctor from 193033 to determine the maximum dry unit weight of soil (Proctor, 1948, Budhu,

The aggregate impact value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, lower aggregate impact value should be preferred. Toughness is the property of a material to resist impact. Due to traffic loads, the aggregate are subjected to the pounding action

Bullas and West [4] reported the aggregate impact value did not, but the aggregate crushing value did separate suitable and unsuitable aggregate for bitumen macadam roadbase. Fookes, Gourley and Ohikere [5] recommended that combinations of physical tests such as impact, crushing and abrasion resistance be used to assess

The aggregate impact value = 10.14%. Discussions: the aggregate impact value gives a relative measure of the resistance of an aggregate to sudden impact, which in some aggregates differs from its resistance to slowly applied compressive load. Aggregate with aggregate impact value higher than 30% may be abnormal.

2.3 Aggregate Impact Value (AIV) Aggregate Impact Value was obtained in accordance with the specifications in [4]. The material for the standard test consists of aggregate passing a 12.5 mm sieve and retained on a 10.0 mm sieve. The sample was surface dried for a period about 4 hours at a temperature not exceeding 110oC. The

The average aggregate crushing value (ACV) and the aggregate impact value (AIV) obtained from the evaluations is 28.7% and 29.5% respectively and are within the acceptable standard limits. The specific gravity and water absorption gave average values of 2.60 and 0.22% respectively while the flakiness index obtained from the analysis is 26.7%.

This test is done to determine the aggregate impact value of coarse aggregates as per IS: 2386 (Part IV) 1963. The apparatus used for determining aggregate impact value of coarse aggregates is

Jitender and Sandeep ( 2014) [5] compared the properties of recycled aggregate and natural aggregates, stated that 100% replacement of NA by RCA will effect on chloride ions resistance and

Aggregate Impact value Test Apparatus, Procedure and uses July 1, ; Rain Gauge: Uses, Types, diagram, rainfall September 25, ; Penetration Test of BitumenProcedure, Apparatus, May 6,

On the basis of analysis of results, obtained in the present investigations, the following conclusions are drawn: (1) The increase of stone aggregate in the brickstone aggregate mix significantly reduces the value of Impact, LosAngeles Abrasion, and water absorption but increases the specific gravity. Limiting value of Impact, abrasion, water
