A proof-roll was performed using a loaded tandem dump truck in the presence of representatives from UES, Lead Edge, and CW Matthews along the A3 extension from Station 41+00 to Station 43+50 (see photos). The subgrade was deemed acceptable throughout the tested area, with the exception of a section near Station 43+00 measuring approximately 30 feet by 15 feet.

UES recommended undercutting this localized area to an additional depth of 1 foot and replacing the material with 12 inches of No. 4 stone. The use of fabric or geogrid was not recommended for this repair by UES.  Remediation was completed on this day by CW Matthews.

The remaining area proof-rolled had Graded Aggregate Base (GAB) placed, watered, and compacted (see photos) but was not completed.

No further observations were made.
