Jul 25, 2019· Aggregate plays a vital role when it comes to pavement construction. To a great extent, the affect of aggregate decides the load transfer capability of the pavements. Apart from that, the aggregate should be strong and posses great durability. Moreover, they should come equipped with proper shape and size to enable the pavement act uniformly.
Aggregate Crushing Value The aggregate crushing value indicates the ability of an aggregate to resist crushing The lower the figure the stronger the aggregate, i.e. the greater its ability to resist crushing The aggregate passing 12.5 mm sieve and retained on 10 mm sieve is selected for standard test Compression testing machine with

Jan 19, 2021· Impact crushers are used to created crushed rock aggregate. The different aggregate sizes and types are appropriate for specific uses in the construction and landscaping industries. For example, although the larger, coarse crushed aggregates are more economical, this type of aggregate can present problems if used in concrete forms for upright structures.
Impact crushers provide better grain-size distribution of RA for road construction purposes, and they are less sensitive to material that cannot be crushed, such as steel reinforcement. Generally, jaw and impact crushers exhibit a large reduction factor, defined as the ratio of the particle size of the input to that of the output material.
Crushing of aggregates during construction process affects the grading, density and strength of a mix or layer made with such aggregate.To measure resistance of aggregate to crushing, the ACV test is carried out on the 14 -10mm aggregate fraction, by applying a 400 KN force gradually over a period of 10 minutes.Test procedure:1) Obtain the ...

The general test procedure of the aggregate impact value test is briefly described below. Objectives of Impact Test. 1. To assess the suitability of the aggregate to be used in the highway pavement. 2. To determine the aggregate impact value. Apparatus Required. 1. An impact testing machine weighing between 45kgs to 60 kgs with a metal base. 2.
Jun 01, 2020· In road construction, local aggregate resources can be utilised through aggregate production on the construction site. The aggregate production process, where construction aggregates are produced from bedrock, often involves several crushing steps. The output is normally considered a product after two or more crushing stages.
Sep 12, 2015· Tests on Aggregate Aggregate plays an important role in pavement construction. Aggregates influence, to a great extent, the load transfer capability of pavements. Hence it is essential that they should be thoroughly tested before using for construction. Not only that aggregates should be strong and durable, they should also possess proper shape and size to […]
Impact Test on Aggregates. Impact value of aggregate will give aggregate capability against sudden loads or forces. For this test also aggregate passing through 12.5mm and retained on 10mm sieve is taken and oven dried. Fill the cylinder with aggregate in 3 layers, 25 strokes of tamping for each layer. Weight w1 noted.

IMPACT CRUSHING Impact crushers may be used as primary, secondary, or tertiary crushers. Despite having a somewhat higher operating cost than other crushers, they tend to produce a more uniform particle shape. Impact crushers usually will benefit the aggregate better than compression crushers, and they may generate more fines.

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.
