Nebuchadnezzar’s dream of a statue made of four metals in Daniel 2 was composed using Persian and Greek historiographic imagery. The crushing of the statue by a stone mountain alludes to the story of the golden calf, and is a message of hope to the Judeans that God will eventually crush their Greek oppressors. | Dr. Naama Golan

Natural aggregate consists of manufactured crushed stone and sand created by crushing bedrock, or naturally occurring unconsolidated sand and gravel. It is a major component of asphalt and concrete and is required in streets, highways, railroads, bridges, buildings, sidewalks, sewers, power plants, and dams—just about every part of the built environment.

Crushed stone varies in size. The number “57” is a number that refers to the size sieve that was used to screen and sort the stone. It means that the stone was put through the #57 sieve which produces gravel stones of about 1” to 1.5” in size. #1 crushed stone refers to the largest sized crushed stone. It is about 2″ to 4″ in size.

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.

Dimension Stone. The compressive strength is the maximum load per unit area that the stone can bear without crushing. A higher compressive strength indicates that the stone can withstand a higher crushing load. The required values range from 1,800 psi (12.45 MPa) for marble to 19,000 psi (131 MPa) for granite.
