Research results are now making their way into codes and standards that govern pervious concrete placement. The four current ASTM standards pertaining to pervious concrete testing will be demonstrated and explained by experts each day at WOC using pervious concrete mixed at the booth, with assistance from students from the Concrete Industry Management program at Middle Tennessee State University. Small-scale placements (stepping stones) will also be molded to show ‘right’ and ‘wrong’ pervious mixes. Visitors will be invited to try their hand with these samples.
Pervious Installer Demonstration
Contractors can earn Pervious Concrete Installer certification by successfully completing a Performance Evaluation. During this live demonstration, attendees will see how installer evaluations are conducted. Certified installers will place pervious concrete using roller screeds. The pervious concrete will be produced onsite using a volumetric mixer.
