Freshwater Pearl? ASTM Testing
A third-party used ASTM Standards to test the strength of Freshwater Pearl?, and found the following results:
ASTM C97 Standard Test Method: 0.338% Absorption by weight; .40% maximum required.
ASTM C97 Standard Test Method: 164.75 lb/ft3 Density; 160 lbs/ft3 minimum required.
ASTM C170 Standard Test Method: 20,459 psi Compressive strength; 19,000 psi minimum required.
ASTM C1353 Standard Test Method: 70.34 HA Abrasion resistance; 25.0 HA minimum required.
ASTM C880 Standard Test Method: 1,515.25 psi Flexural strength; 1,200 psi minimum required.
A third-party used ASTM C1549 Standard Test Method to test the solar reflectivity of Freshwater Pearl? and Freshwater Pearl? with a flamed finish obtained a 0.45 solar reflectivity. Using the LEED v4 rating system for LEED Certification, you can receive 2 points as a result of Heat Island Reduction. To achieve 2 points for a non-roof area, the paving material must score a .33 solar reflectivity or higher upon installation.
