course on Concrete Pavement Design Details and Construction Practices presents current guidelines and recommendations for designing and constructing durable, long-lasting concrete pavements. A Technical Digest reference manual has been prepared that summarizes the most current design and construction recommendations. This training course presents the information contained in that document in a series of eleven sessions, each focusing on a specific topic: Session 1—Overview Session 2—Concrete Pavement Type Selection and Design Features Session 3—Subgrade Session 4—Drainage Design Considerations Session 5—Base Considerations Session 6—Thickness Design Session 7—Joint Design Session 8—Shoulder Considerations Session 9—Construction Considerations Session 10—Special Considerations for Reinforced Pavements Session 11—Summary and Wrap-Up The focus of the course is on the design and construction of jointed plain concrete pavements (JPCP). However, a separate session on special considerations for reinforced pavements (both jointed reinforced concrete pavements [JRCP] and continuously reinforced concrete pavements [CRCP]) is included. As part of the course, a series of five workshops will be conducted. In these workshops, participants, working in groups, will walk through an entire concrete pavement design, applying the concepts and guidelines described in the presentations. Overall Course Objectives The overall objectives for this training course are: 1. Recognize the effect of critical concrete pavement design details on overall concrete pavement performance. 2. Identify critical pavement construction practices that impact performance. 3. Select appropriate concrete pavement design details to enhance the performance of the pavement for given specific design conditions. Concrete Pavement Design Details and Construction Practices—Participant’s Workbook 1 INTRODUCTION About This Workbook This Participant’s Workbook has been assembled to augment the formal presentations of the Concrete Pavement Design Details and Construction Practices training course. It has been developed to assist participants in following the presentation of the course materials and to facilitate the comprehension of the information. However, it is not intended as a replacement for the Technical Digest reference manual, which provides more detailed information on the various course topics. This Participant’s Workbook contains a section corresponding to each training session. These sections consist of the following items: Cross reference information to the applicable pages of the Technical Digest. A brief overview of the information to be presented in the session. An outline of the information to be presented. A list of review questions applicable to the session. A list of key references for additional information on the topic. A reproduction of the presentation graphics used in the session, presented in two-column format to allow note-taking by the participants during the presentation. The above information is provided for each of the eleven training sessions. Because of these features, participants should have no trouble following along during the technical presentations and will more easily recognize the key discussion points of each session. To further aid the participant, a glossary of key technical terms used in the training course and in the Technical Digest is found at the end of the Participant’s Workbook. Course Schedule This training course is intended to be completed over 2 days of instruction. A generic course schedule for this training course is found on the next page. This schedule provides the approximate starting and ending times for each session or workshop, as well as anticipated break and lunch times. The actual times for each of these will undoubtedly vary depending upon the flow of the course. The schedule also provides a cross reference to the document corresponding to the specific activity. Note that session 10 on reinforced pavements is an optional session. The presentation of this session should be considered for agencies that construct reinforced pavements or have expressed a specific interest in these pavement types. 2 Concrete Pavement Design Details and Construction Practices—Participant’s Workbook INTRODUCTION CONCRETE PAVEMENT DESIGN DETAILS AND CONSTRUCTION PRACTICES Course Schedule Time Topic/Activity Reference Day One 1:00 – 1:45 p.m. Course Introduction Chapter 1, Technical Digest 1:45 – 2:30 p.m. Introduction to PCC Pavement Types Chapter 2, Technical Digest 2:30 – 2:45 p.m. 2:45 – 3:45 p.m. Subgrade Chapter 3, Technical Digest 3:45 – 4:45 p.m. Workshop 1: Selection of Design k-value Participant’s Workbook 8:00 – 8:15 a.m. Review of Day 1 None 8:15 – 9:15 a.m. Drainage Design Considerations Chapter 4, Technical Digest 9:15 – 10:00 a.m. Base Considerations Chapter 5, Technical Digest 10:00 – 10:15 a.m. 10:15 – 11:00 a.m. BREAK Day Two 11:00 – 12:00 noon BREAK Workshop 2: Base and Drainage Selection Participant’s Workbook Thickness Design Chapter 6, Technical Digest 12:00 – 1:00 p.m. 1:00 – 2:15 p.m. 2:15 – 2:30 p.m. 2:30 – 4:00 p.m. Joint Design Chapter 7, Technical Digest 4:00 – 4:45 p.m. Shoulder Considerations Chapter 8, Technical Digest 8:00 – 8:15 a.m. Review of Day 2 None 8:15 – 9:15 a.m. Workshop 4: Final Pavement Design Participant’s Workbook 9:15 – 9:30 a.m. 9:30 – 10:15 a.m. Construction Considerations Chapter 9, Technical Digest 10:15 – 11:00 a.m. Design Considerations for Reinforced Pavements (optional) Chapter 10, Technical Digest 10:15 – or 11:00 – 11:00 – or 11:45 – 11:00 a.m. Workshop 5: Cost Effectiveness of Design Features Participant’s Workbook Summary and Wrap Up None LUNCH Workshop 3: Preliminary Thickness Design Participant’s Workbook BREAK Day Three 11:45 a.m. 11:15 a.m. BREAK 12:00 noon Instructors: Instructor A Instructor B Concrete Pavement Design Details and Construction Practices—Participant’s Workbook 3 INTRODUCTION Key Technical References The Technical Digest serves as the primary source of information for this training course. It is a good summary of the state of the practice in concrete pavement design, but because it is a synthesis, it does not contain extensive details or supporting data. A complete annotated bibliography is included within the Technical Digest for those who seek more information on a particular topic. Moreover, the following “short list” of references is provided to identify what are believed to be the most useful and applicable sources of current information for the concrete pavement practitioner; these references cover in much greater detail the various aspects of concrete pavement design. 1.
