Standard of Crushing Value of Coarse Aggregates for

Jan 20, 2020 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.

What is Coarse Aggregates Types Classification

Oct 02, 2021 The Aggregates which will get retained on the 4.75 mm (No. 4) sieve and will pass through a 3-inch sieve are known as Coarse aggregate. The aggregates used in the production of concrete are inert granular materials such as gravel, crushed stone, sand, slag, and recycled concrete. The aggregates might be natural, manufactured, or recycled.
