Common use of Pavement Design Clause in Contracts

Pavement Design. Developer shall design, construct, and maintain roadway pavements using Good Industry Practice and the subsurface geotechnical data collected by the Developer. Roadway pavements shall meet the operation standards and requirements contained in Sections 19 and 22. Developer shall prepare a pavement design report for record that documents the assumptions, considerations, and decisions contributing to the Developer’s pavement design, including the following: • Pavement design details by location, including structural layer materials, general specifications, and thicknesses • Lifecycle management analysis, including the periods for resurfacing, reconstruction, and other rehabilitation measures and what these activities are likely to entail • Relevant pavement evaluation data (structural and functional) and condition information on adjacent roads • Site conditions • Relevant geotechnical data and drainage requirements • Design criteria used in determining the pavement design(s), including annual average daily traffic, percentage heavy vehicles, cumulative traffic loading, pavement material strength factors, and pavement design life • Design methods adopted in developing the pavement design(s) and the rationale for their selection • Other considerations used in developing the pavement design(s) • The pavement for main lanes and ramps shall be designed using the functional highway classification(s) defined in Book 2 For roadways adjacent to and crossing the Project that are disturbed by the construction activities of the Project, Developer shall, at a minimum, match the in-place surface type and structure of the existing roadways. Developer shall design all tie-in work to avoid differential settlement between the existing and new surfaces.
