AET Project No. 20-06374 — Page 7 of 8 <br /> Our observations of the bolted connections indicated that the plies of the observed connections <br /> were in intimate contact and satisfied the requirements of the referenced codes and applicable <br /> project plans and specifications. <br /> Our observations of the deck welds and mechanical fasteners satisfied the referenced codes and <br /> applicable project plans and specifications. <br /> BITUMINOUS PAVEMENT SUBGRADE <br /> We observed test-rolls performed on the subgrade for the bituminous drive and parking areas <br /> south and east of the building between July 20 and Ju1y 25, 2007. The test-rolls were conducted <br /> with a loaded tandem axle dump truck. We observed the reaction of the subgrade soils below the <br /> wheels as the vehicle made passes over the pavement areas. The results of these services were <br /> presented in our letter dated July 26, 2007. Briefly, that report states that we observed six areas <br /> of the subgrade that exhibited excessive deflection and/or rutting. We recommend subcutting the <br /> subgrade 4" or ]2", placing geotextile fabric, and placing additional class 5 aggregate base in <br /> these six areas. We did not observe the recommended corrections. <br /> CLOSURE <br /> To protect the client, the public and American Engineering Testing, Inc., this report (and all <br /> supporting information) is provided for the addressee's own use.
