Significance of Aggregate Crushing Value Test. The crushing value test is conducted on aggregates that are used for the construction of roads. Lower crushing value aggregates give much more durability for roads due to its lower crushed fraction under the compression load. The road is subjected to motion pressure continuously.
Other articles where crushing strength is discussed: compressive strength test: The crushing strength of concrete, determined by breaking a cube, and often called the cube strength, reaches values of about 3 tons per square inch, that of granite 10 tons per square inch, and that of cast iron from 25 to 60 tons per square inch.
Procedure The aggregate sample: The material for the standard test consists of aggregates sized 10.0 mm to 12.5 mm.The aggregates must be in a surface dry condition before testing. The aggregates may be dried by heating at 100 oC – 110 o C for not more than 4 hours and cooled to room temperature before testing, if necessary.
