Frank, If is sounds good to you, I will have Helmberger place this note on the paving sheet for the project. Please let me know your thoughts. Thanks, Clay Barnett, P.E. Town Engineer Town of Addison 16801 Westgrove Drive Addison, TX 75001-2818 Office: (972) 450-2857 From: McIllwain, Frank O. [mailto:FOMcIllwain@GarverUSA.com] Sent: Wednesday, June 23, 2010 2:54 PM To: Clay Barnett Subject: RE: ExecHangar CBR Test Results Clay: We have reviewed the current pavement design and geotechnical information to justify the modulus values used in the pavement design. I’m ready to approve the design contingent upon the following: If there is not enough recycled pavement to use as base course material, the owner must revise the pavement design and resubmit pavement design and geotechnical testing results to justify modulus values used in the pavement design. Construction of pavement section with base course material other than recycled pavement shall not be permitted without approval of the new pavement design. Feel free to call me if you have any questions. Frank McIllwain, PE Garver From: Clay Barnett [mailto:cbarnett@addisontx.gov] Sent: Friday, June 18, 2010 1:39 PM To: McIllwain, Frank O.
