Bruce Dietrich, P.E. State Pavement Design Engineer RIGID PAVEMENT DESIGN MANUAL CHAPTER 1 INTRODUCTION 1.1 PURPOSE

The objective of this manual is to provide a Pavement Design Engineer with sufficient information so that the necessary input data can be developed and proper engineering principles applied to design a new rigid pavement, or develop a properly engineered rehabilitation project. This design manual addresses methods to properly develop a rehabilitation project and the computations necessary for the pavement design process. It is the responsibility of the Pavement Design Engineer to insure that the designs produced conform to Department policies, procedures, standards, guidelines, and good engineering practices. 1.2 AUTHORITY

Sections 20.23(3) (a) and 334.048(3) Florida Statues 1.3 SCOPE

The principal users of this manual are the District Pavement Design Engineers and their agents (i.e. consultants). Additional users include other departmental offices such as Construction, Maintenance, Traffic Operations, etc. and city and county offices.

GENERAL

Chapter 334 of the Florida Statues, known as the Florida Transportation Code, establishes the responsibilities of the state, counties, and municipalities for the planning and development of the transportation systems serving the people of the State of Florida, with the objective of assuring development of an integrated, balanced statewide system. The Code's purpose is to protect the safety and general welfare of the people of the State and to preserve and improve all transportation facilities in Florida. Under Section 334.048(3), the Code sets forth the powers and duties of the Department of Transportation to develop and adopt uniform minimum standards and criteria for the design, construction, maintenance, and operat
