Load applied by Compression Testing Machine in the test is? Q3. In crushing test, the aggregate used is passing through ________mm sieve and retained on ________mm.
Feb 03, 2017 · One of the model in which pavement material can fail is by crushing under compressive stress. A test is standardized by IS: 2386 partIV and used to determine the crushing strength of aggregates. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load.
Trilab's specific aggregate testing range includes: Degradation Factor – Source Rock and Coarse Aggregate. Crushed Particles in Coarse aggregate derived from gravel. Materials finer than 75 Microns in aggregates (by washing) Aggregate Soundness – .
Imported Aggregates Testing. Since early 2007 Building and Construction Authority of Singapore (BCA) has adopted a threestage testing regime on imported aggregates to determine the quality of aggregates imported from overseas sources. Since beginning, Admaterials has provided imported aggregate testing for the following tests as required by BCA.
The Los Angeles () abrasion test (Figure 1) is a common test method used to indie aggregate toughness and abrasion characteristics. Aggregate abrasion characteristics are important because the constituent aggregate in HMA must resist crushing, degradation and disintegration in order to produce a high quality HMA.
Mar 16, 2018 · To carry out the aggregate abrasion value test, the following are the procedures used: 1. The cover of the machine is remove and the sample x y is pour above into the machine. 2. The abrasion charges is place on the sample and the cover is fix back firmly. 3.

The procedure of the impact value test includes the following series of steps: 1. The aggregate samples of size 10mm to (passing through sieve and retained on 10mm sieve) are first taken and ovendried at a temperature ranging from 100 degrees Celsius to 110 degrees Celsius for about four hours. 2.
Test Method: IS: 2386 (P1) 1963. Impact Value: This test helps in determining the value which indies the ability of an aggregate to resist crushing. The lower the figure the stronger the aggregate, the greater its ability to resist crushing. Test Method: IS: 2386 (P .
Mar 21, 2018 · • Aggregate Impact Values, AIV's, below 10 are regarded as strong, and AIV's above 35 would normally be regarded as too weak for use in road surfaces. • Aggregate Impact Values and Aggregate Crushing Values are often numerically very similar, and indie similar aggregate strength properties. Recommended Aggregate Impact Test Values
The data on the table attached was compiled during an Aggregate Crushing Value test (ACV). The mass passing mm of sample 2 is: 2. The data on the table above was compiled during an Aggregate Crushing Value test (ACV). The aggregate crushing value of sample 2 is: 3.

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 Objective To determine the impact value of the road aggregates Equipment cylinder rod sieve Procedure 1.
Aggregate Testing Equipment. Providing you the best range of aggregate crushing value test apparatus, los angeles abrasion test apparatus, air entrainment meter, aggregate impact value test apparatus and flakiness elongation index test gauges with effective timely delivery.
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 crushing value test of aggregate provides the resistance of an aggregate sample to crushing under gradually applied compressive load. Generally, the test is conducted on aggregate passing mm and retained on a 10 mm sieve.
Precaution Of Aggregate Crushing Value Testing. The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 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. Get Price
