Bryce Simons on Specific Gravity and Absorption

On September 28, Bryce Simons did a presentation for the HAPI QC members titled “Specify Gravity and Absorption of Aggregate by Volumetric Immersion Method (Phunque Test). This method has been thoroughly evaluated and is approved as AASHTO T354. It is also in the balloting process for ASTM as an alternate method for C127 and C128. While under development, a round robin in which 6 states as well as the FHWA lab in Virginia participated found that this method is approximately 3 times more consistent than the conventional test. Additionally, NCHRP Study 344 found that this is the most repeatable and operator independent method there is.

Bryce has been a Materials Engineer for well over 30 years, and have practiced for over 18 years on the private side and 17 years on the public side.  He has recently been retained as the Senior Materials Advisor to the Ministry of Transportation in Saudi Arabia and will be going over there to support their efforts soon. He has dealt extensively and in-depth with all types of construction materials, including asphalt, concrete, wood, steel, epoxy’s & Plastics, etc.
