Joe, Please add the following note to the paving plan: “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.” Please submit at least five copies of the revised drawings to issue for construction. If you have any questions, please feel free to contact me. Thanks, Clay Barnett, P.E.
