Standard of Crushing Value of Coarse Aggregates for ...

Crushing resistance of coarse aggregate is the key to the stability and durability of the skeleton structure of permeable asphalt (PA) mixture. To determine the technical requirements of crushing value of coarse aggregate used in PA mixture, step-loading compression tests were conducted on the mixtures of PA-13 and a control asphalt mixture AC-13, respectively.

02/12/2020  Coarse Aggregate Definition. The Aggregates which will get retained on the 4.75 mm sieve or the aggregates which have size more than 4.75 mm are known as Coarse aggregate. Origin of Aggregates . Aggregates are commonly obtained by crushing the naturally occurring rocks. The properties of the rocks are mainly depended upon the type of rock whether it is sedimentary rocks,

Strength of Coarse Aggregates

Strength of coarse aggregates is difficult to measure. While we talk about the strength of coarse aggregates it refers to the crushing strength of the aggregate itself. However, the required information on strength of coarse aggregates can be obtained from indirect tests: crushing strength of prepared rock samples, crushed value of bulk aggregate, and performance of aggregate in concrete ...

3. Results and Discussions 3.1. Crushed Aggregate’s Effects on Slumps of Concrete. The Figure 1 depicts slum value of A-1 coarse aggregates for all five groups. For Impact Crushed (A-1) coarse aggregates slump values were evaluated for all five groups and it was evident from experiment that, there was a steady decrease in slump value with the decrease of w/c ratio.

Properties of Aggregates - Civil Snapshot

01/02/2021  The aggregate crushing strength value is a useful factor to know the behavior of aggregates when subjected to compressive loads. Impact Value. The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact. The impact value of an aggregate is sometime used as an alternative to its crushing value.
