The purpose of this method is to determine the crushing value of the given sample of aggregate for the road construction works. The Principal mechanical properties required in road stones are: Satisfactory resistance to crushing under the roller during construction and Adequate resistance to surface abrasion under traffic. Also stresses under rigid tyre rims of…

samples used were collected from six different quarries in Mpape, Abuja, Nigeria, measuring approximately 31.5 to 50mm, uniformly graded crushed hard stone which is durable, angular, …

The Los Angeles abrasion value (LAAV) test is the most widely used method for measuring aggregate resistance to abrasion. The test measures the resistance of aggregate to wear due to attrition between rock particles and also to impact and crushing by steel spheres (Kahraman and Fener 2007). Aggregate crushing value (ACV) and aggregate

Impact test, and Crushing value test are shown in Table 3. It can . be observed from Table 3 that compaction values for samples . S3, S8, S9, and S10 are highest compared to other samples. It .

Aggregate Crushing Value = (B/A) X 100 Where A = weight of oven-dried sample B = weight in 'g' of fraction passing through 2.36 mm IS sieve. 6. Results The mean of the two results shall be reported 7. Video Aggregate Crushing Value Test 8. Download Download PDF

NOTE 1 -The 'aggregate crushing value' gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggre- gate of 'aggregate crushing value' 30 or higher, the result may be anomalous, and in such cases the 'ten percent fines value' should be determined instead. ...

Figure 2 indicates that the 9.5mm granites from Omologede and Ishara has the highest specific gravity values of 2.78 followed by that of Ago – Iwoye with the value of 2.72, while that of Papa …

Calculation of Aggregate Crushing Value. 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 …

7: Aggregate impact value apparatus AGGREGATE CRUSHING VALUE (ACV) This test provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.

Aggregate Crushing Value (ACV). However, ... (Southeastern Nigeria). Results indicated that the shale samples have Atterberg limits that might be considered moderate to high; while Liquid Limit ...

The crushing value of aggregates is rather insensitive to variation in strength of weaker aggregates. For this reason, a simple test known as 10 percent fine value is introduced. When the aggregates crushing value become 30% or higher, the results are likely to be inaccurate. Aggregate Crushing Load (Source: IS 2386(Part 4):1963) The aggregates ...

In addition to material strength (Xuan et al., 2015;Li et al., 2017), the crushing characteristics of the aggregates are essential to ensure road stability.

crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead. Fig. 1: Balance Balance should be accurate upto 1 gm. Fig. 2: Sieve (12.5 mm, 10.0 mm and 2.36 mm) Fig. 3: Mould, Measuring Cylinder with Plunger

This paper reports an experimental investigation carried out to establish a mathematical relationship between aggregate crushing value (ACV) and ten percent fines aggregate …

In this paper, the physico-mechanical properties of the aggregates used in describing their strength and durability include aggregate crushing value (ACV), aggregate impact value (AIV), Los Angeles abrasion value (LAAV), water absorption, bulk density and specific gravity.

affected, the strength of coarse aggregate is assessed by aggregate crushing test. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied …

3. AGGREGATE ABRASION VALUE AIM :- To determine the abrasion value and hardness property of aggregates as per IS: 2386 (Part IV) - 1963. APPARATUS :- 1) Los Angles abrasion testing machine 2) IS Sieve of size - 1.7mm 3) Abrasive charge - 12 nos. cast iron or steel spheres approximately 48mm dia. and each weighing between 390 and 445g ensuring …

This paper reports an experimental investigation carried out to establish a mathematical relationship between aggregate crushing value (ACV) and ten percent fines aggregate crushing value (TFV) for some aggregates in Nigeria. Such a mathematical relationship, usually established through regression modelling on data collected, is useful in …

Aggregate crushing value = (W2 x 100) / (W1-W) W2 =Weight of fraction passing through the appropriate sieve W1-W =Weight of surface dry sample. The mean of two result to nearest whole number is the aggregate crushing value. Result The aggregate crushing value of the given sample= Aggregate Crushing Values for Roads and Pavement Construction
