Civil Engineering Lab II (Group 3) Highway Engineering 1 – Report 3 HW1 – 3: AGGREGATES CRUSHING VALUE (ACV) TEST Objective a) To determine the aggregates crushing value of coarse aggregates b) To access suitability of aggregates for use in different types of road pavement T heory Aggregates Crushing Value (ACV) gives a relative measure of resistance of aggregates to crushing .
Aggregate Crushed Value Of Crushed Stone. What type of rock shouldbe crushed for aggregate aggregate crushed value of crushed stone what type of rock shouldbe crushed for aggregate crushing value is a simple video slideshow, if you want to know more details, please click on our website http//com, we will. More Details. suijitupian131 ...
· Particle size distribution curves of recycled aggregates from building demolition concrete crushed by jaw and impact crushers. The jaw crusher produced 60% of coarse aggregates in weight, whereas the impact crusher produced 49% coarse aggregates. The proportion of particles finer than mm is around 7–8% weight for both crushing mechanisms.
· Procedure to determine Aggregate Crushing Value i) . Various Lab Test On Aggregates; . determination aggregate crushing value theory –
ACV (Aggregate Crushing Value) and 10% FACT (Fines Aggregate Crushing Test) The test results are used for quality control, by means of particle strength, of aggregate for concrete, surfacing (chips) and asphalt, as well as crushed stone base. The wet and dry results can be used as a guide to indie aggregates that are likely to break down ...
aggregate crushing value of the coarse aggregates used for cement concrete pavement at surface should not exceed 30 percent. For aggregates used for concrete other than for wearing surfaces, the aggregate crushing value shall not exceed 45 percent, according to the ISS.
· aggregate bedding, have a required minimum percent crushing. The percent crushing referred to in that specifiion is not the same as Sections, or Differences are as follows: 1. Percent crushing can be determined by samples taken from stockpiles prior to crushing. This is primarily a field test;
2. It is the intent of this test method to only determine the percent of crushed particles created by crushing or other mechanical means and not the additional crushed/fractured aggregates created by laboratory processes. With this in mind, it is important that the tester handle aggregates for this test carefully. J. HEALTH AND SAFETY
Laboratory test equipment for the Aggregate Impact Value (AIV) and the Aggregate Crushing Value (ACV) and Ten Percent Fines Value (TFV) are also available. The Pendulum Skid Resistance Tester provides highway engineers with a method of checking the resistance of wet and dry surfaces to slipping and skidding, both in the lab and insitu.
Crush Resistance Testing. Crush resistance testing involves the measurement of a compressive load to a point when a sample deforms, fractures, shatters or collapses. This type of test may be applied to a variety of products including corrugated cardboard, glass, bearings, bricks, concrete, or any sample where crush resistance is important.

2 Weigh the suitable sample of aggregate and keep it in a container, put the cover on. 3 T he weight of the container with the cover and the gravel is (B). 4 Remove the cover, then put the sample in the oven at 105 °C for 24 hours. 5 Remove the sample forms the oven and put .
· Aggregates with lower crushing value show a lower crushed fraction under load and would give a longer service life to the road and hence a more economical performance. If we used a weaker would get crushed under traffic loads, would produce smaller pieces not coated with a binder, and these would be easily displaced or loosened out resulting in loss of the surface/layer.
· According to VicRoads (2013), crushed rock aggregates are egorised into four classes, with classes 1 and 2 being base course materials and classes 3 and 4 being subbase materials. The egorisation is based on several parameters, including the material grading, liquid limit, plasticity index, California Bearing Ratio, flakiness index, permeability and LAV limits.
· The determination of aggregate crushing strength is an important test in your civil engineering know that aggregates are the one the basic unit of building are used in several construction processes such as in concrete, road construction etc..
· The crushed aggregate is allowed to pass through mm IS sieve. And the impact value is measured as percentage of aggregates passing sieve (W2) to the total weight of the sample (W1). Aggregate impact value = (W1/W2)*100. Aggregates to be used for wearing course, the impact value shouldn't exceed 30 percent.
· Aggregate Impact Values and Aggregate Crushing Values are often numerically very similar, and indie similar aggregate strength properties. Classifiion of aggregates using Aggregate Impact Value is as given below: Aggregate Impact Value Classifiion <20%.= Exceptionally Strong 10 – 20% .=Strong 2030%. =Satisfactory for road surfacing >35%.= Weak for road surfacing
Description Aggregates crushing value: The aggregates crushing value is the ability of an aggregate to resist crushing under a gradually applied compressive load. Impact value: is the resistance of an aggregate to sudden or impact load. Aggregates crushing value: is the resistance of an aggregate to gradually / continuously applied load.
