Title
Consider a memorandum/resolution adopting the 2022 Pavement Design Manual.
Summary
DATE: November 29, 2022
TO: Kent Cagle, City Manager
FROM: Edwin Revell, Executive Director Development Services
SUBJECT: Adoption of the 2022 Pavement Design Manual
BACKGROUND AND FINDINGS:
The City is currently working to update the pavement design requirements throughout the City. The pavement design manual will allow for requirements to extend the design life of the pavement before necessary repairs will be needed. It was observed in the recent winter storms that the repair needs on the existing roadways is a high cost and will take time to “catch up.” To address this issue, staff has worked to improve our design standards with the development of a new Pavement Design Manual (PDM). The City contracted with Raba Kistner Consultants, Inc. in September of 2020 to develop a PDM based on current practices and methods used in the surrounding area. The design methodology follows TXDOT’s current Flexible Pavement Design System (FPS21) design software program published in 2021. This program and design methodology has been used and adopted by several cities throughout Texas. The manual requires a geotechnical analysis and pavement design for all arterial roadways. For local residential roadways there is a minimum standard table provided for areas that meet the soils requirement without a geotechnical pavement design. The adoption of this resolution will ensure all references related to the pavement design manual in City Code and published standards will be for the 2022 Pavement Design Manual.
The PDM will allow the City to better manage the design and construction of the its infrastructure and will provide clear and consistent guidance to developers.
