Supplement this section with the following:

Contractor shall conduct infiltration tests on the finished PHMA/PWMA per ASTM C1701 at locations chosen by the Engineer.   Newly-placed PHMA/PHWA shall have a minimum infiltration rate of 100 inches/hour.  I Infiltration tests shall be completed every 150 linear feet of roadway and conducted in accordance with ASTM C1701. 

If the measured infiltration rate is less than 100 inches/hour, the Contractor shall conduct an additional four infiltration tests in line with the paver direction of travel.  Two tests upstream and two tests downstream of the initial test locations shall be taken at distances of 20 feet and 40 feet.  Results of the additional tests will be averaged.  The Contractor shall conduit additional testing upstream and downstream to identify area to be removed.  If the average infiltration rate is less than required remove and replace the failing section at the direction of the Engineer and at no cost to the Contracting Agency.
