Aggregate Crushing Value Test Determine Aggregate. Aggregate crushing value is defined as the percentage by weight of the crushed or finer material obtained when the test aggregates are subjected to a specified load under standardized conditions and the strength of the aggregate used in road construction is expressed by numerical index . Live Chat
Dec 15, 2017· Aggregate Impact Values and Aggregate Crushing Values are often numerically very similar, and indicate similar aggregate strength properties. Classification of aggregates using Aggregate Impact Value is as given below: Aggregate Impact Value Classification <20%.= Exceptionally Strong 10 – 20% .=Strong 2030%. =Satisfactory for road surfacing >35%.= Weak for road surfacing
Protect the sample from moisture loss from the time the sample is taken to the time it is molded. Do not exceed 15 minutes. Determine the temperature according to ND T 309, slump to ND T 119 and air content according to ND T 152. The results of the slump test will determine the method of consolidation.

Generally, aggregate is not shipped more than 35 50 miles from the excavation site to end users. Because of the investment required for modern aggregate operations (time and capital), companies typically require a minimum of 15 to 25 years of reserves to open a quarry.
AIM 1) To determine the aggregate crushing value of coarse aggregates 2) To assess suitability of aggregates for use in different types of road pavement 2. PRINCIPLE The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Crushing value is a measure of the strength of the aggregate. The aggregates should therefore .
