Prepare Pavement Design. CONSULTANT will provide a pavement design using information obtained in the Geotechnical Investigation and calculate the pavement sections required to support the design vehicle or aircraft fleet mix using FAA Advisory Circular 150/5320-6E, Airport Pavement Design and Evaluation. The analysis will be included in the Engineer’s Design Report. The following effort will be completed under this task:
Prepare Pavement Design. After receiving the geotechnical investigation data, the Engineer will analyze the data and prepare a proposed pavement section using current FAA design software (FAARFIELD). In addition to determining the proposed pavement section for the current and anticipated traffic, a pavement classification number (PCN) analysis will be performed to determine the runway PCN classification based on the expected fleet mix. The Engineer will submit the FAARFIELD computer printouts with a narrative to the FAA. The following tasks will be completed: ✈ Determine appropriate data for pavement design. ✈ Input data for computer modeling with topographical survey data. ✈ Prepare an exhibit showing the existing pavement and base course thickness. ✈ Determine areas of existing pavement to be removed and replaced. ✈ Prepare pavement and soils information for incorporation on the construction drawings. ✈ Verify elevation of water table. ✈ Compile the current airport fleet mix. ✈ Input data into FAARFIELD. ✈ Run pavement design scenarios. ✈ Analyze output from FAARFIELD. ✈ Select preferred pavement section. ✈ Compare pavement section to FAA Advisory Circular (AC) 150/5320-6 (Current Edition), Airport Pavement Design and Evaluation. ✈ Verify frost design method. ✈ Verify overexcavation requirements (if needed). ✈ Verify optimum moisture content for subgrade preparation.
