Crushed stone is produced by crushing quarry rock, boulders, cobbles, or largesize gravel. Crushed aircooled blastfurnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the pit or plant. Some variation in the type, quality, cleanliness, grading, moisture content, and other properties is expected.

 · The aggregate crushing strength value is a useful factor to know the behavior of aggregates when subjected to compressive loads. Also read: Crushing Value Test of Aggregates. 13. Impact Value. The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact.

 · Crushed Stone Grade 110. Generally, as the grade number goes up, the size of the stone goes down. #1 – The # 1 crushed stone grade is the largest of the crushed stone grades and includes stone between 24 inches long. This material is great for larger jobs or for filling in larger holes. #3 – This size of the stone ranges from 1/2 to 2 ...

The Fine Aggregate Test (ASTM C128 and AASHTO T 84) is a comparison of sample masses in ovendry, saturated surfacedry (SSD), and immersed conditions. This test method offers alternate procedures to determine specific gravity. Either a volumetric flask or a simple pycnometer can be used for the gravimetric procedure. For the volumetric procedure, a special Le Chatelier flask is .
