Aggregate Impact Value Test is an ability or toughness of aggregates which resist sudden impact or shock load on it. It is important in pavement Design.
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.
The aggregate crushing value, which is an inverse measure of mechanical strength of aggregate, is determined by the percentage of fines passing through 2.36 mm IS sieve after test and it is ...
Compaction Equipment. There are four broad categories of soil compaction equipment: handheld rammers and tamping plates, vibratory and static sheepsfoot, vibratory and static rollers, and pneumatic tire compactors. Rammers and Tamping Plates Often referred to as "jumping jacks," handheld vibratory plate compactors and rammers …
Rollers are useful construction tools that compact and level different types of soil. Learn about the types of rollers that can be used for your next project.
Sheepsfoot rollers are also known as tamping rollers. They resemble a smooth drum roller with projecting club-shaped feet fixed to the drum's surface in a regular pattern. The roller drums themselves are empty, and the additional weight is provided by water or sand fill. The operating mass of a sheepsfoot roller can vary between 5 and 8 …
The Aggregate Crushing Value (ACV) Test Set measures how resistant an aggregate is, when being crushed under a gradually applied compressive load. Each set consists of steel cylinder, plunger, base plate, cylindrical measure and tamping rod. For durability and reliability, all parts of the apparatus are galvanized steel or powder coated, heat treated …
Soil compaction is defined as the method of mechanically increasing the density of soil. In construction, this is a significant part of the building process.
7.7.1.1 Introduction. One of the requirements, for the suitability of aggregates for construction, is the ability of the aggregate to resist crushing. The Aggregate Crushing Value gives a relative measure of the resistance of the aggregate to crushing under a gradually applied compressive load.
Using a vibratory roller on your construction project can help keep the building's structural integrity. Other types of soil that vibratory rollers are great at …

In conjunction with the TFV test, insights from assessments such as the Aggregate Crushing Value(ACV) and aggregate impact value(AIV) tests are indispensable. This synergistic approach provides a comprehensive profile of the material's characteristics, enabling informed decisions in construction planning.
Principle. Aggregate used in road construction, should be string enough to resist crushing under traffic wheel loads. If the aggregate are weak, the satbility of the pavement structure is likely to be adversly affected. The strength of coarse aggregates is assessed by aggregates crushing test. The aggregate crushing value provides a relative ...

The materials used were from 4 t stockpiles. Laboratory samples of approximately 125 kg were taken in accordance with BS 812-102, and one laboratory sample of each material was sent to each laboratory. Two test portions were prepared from each laboratory sample for the determination of the aggregate crushing value.
