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.

CALCULATION: • Aggregate crushing value = B/A x • The result should be recorded to the first decimal place and the mean of the two results reported. • To achieve a high quality of pavement, aggregate possessing low crushing value should be preferred. 8.
Procedure of Aggregate Impact Test. The test sample consists of aggregates sized 10.0 mm 12.5 mm. Aggregates may be dried by heating at 100-110° C for a period of 4 hours and cooled. (i) Sieve the material through 12.5 mm and 10.0mm IS sieves. The aggregates passing through 12.5mm sieve and retained on 10.0mm sieve comprises the test material.
Procedure. Step 1 – First, the aggregate sample sieve through 12.5mm sieve and collect it which is retained in 10 mm sieve. Step 2 – Now, the sample should be dried through the oven up to 4 hours at 100 deg to 110 deg. Step 3 – Then, the aggregate sample should be filled in the metal cup by 3 layers. Each layer should be tamped 25 times by the tamping rod.

Aggregate crushing value test astm pdf Abrasion Test is the measure of 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 Small-Size Coarse Aggregate by Abrasion and Impact in Los Angeles Machine.
aggregate crushing value test conclusion ; What Is a "conclusion Sentence"? A "conclusion sentence" is a sentence at the end of an essay that must tie together the essay and reaffirm the author's argument. Before the author arrives at the conclusion sentence, the essay needs to begin with an introduction, include body paragraphs with ...
Testing the compressive strength of the aggregate particles is not normally carried out to determine its strength or suitability. This property is normally determined by a simpler method such as the Aggregate Crushing Value (ACV) or the Los Angeles Abrasion test which also gives a measure of the abrasion resistance and "toughness" of the aggregate.
Therefore, aggregate used for such propose should have sufficient toughness to resist their disintegration due to the impact. This important property of aggregate is determined by the aggregate impact value test. This resistance of aggregate may differ from resistance to gradual load which we measure in the crushing value test.
The aggregate crushing value is an essential index in the construction of road bases and is defined as the mass percentage of fine particles after a confined compression test of recycled CDW.

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 indicate similar aggregate strength properties. Aggregate Impact Value; Test Specifications:
Results and Conclusions - UAEU From test results it could be noted that aggregate sample do not fit the standards limits ... Table 2.3 gives the test results for the crushing value for aggregates.
Abrasion Test is the measure of aggregate toughness and abrasion resistance such as crushing, degradation and disintegration. The percentage wear of the sample aggregates due to rubbing with steel balls is determined and is known as Los Angeles Abrasion Value.

Mechanical Properties of Aggregates Aggregate Crushing Value Test (BS:812, part 3) Procedure • The material to be tested should pass a 14.0 mm (1/2 in.) sieve and be retained on a 10 mm (3/8 in.) sieve. • Dry the sample in an oven at 100-110 0 C for four hours. • Place the sample in a standard cylindrical mould and tamp it. • Put a plunger on the top of the aggregate and place the ...
Aggregate Crushing Value. 1.0 Introduction. The principal mechanical properties required in stones are satisfactory resistance to crushing under the roller during construction and adequate resistance to surface abrasion under traffic. Aggregates used in road construction, should be strong enough to resist crushing under traffic wheel loads.
The aggregate crushing value for cement concrete pavement shall not exceed 30%. The aggregate crushing value for wearing surfaces shall not exceed 45%. PURPOSE OF TEST: The strength of coarse aggregate is assessed by aggregate crushing test, the aggregate value provide the relative measure of resistance to crushing under gradually applied ...
Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.
