11 Comprehensive Concrete Pavement Design  More than just slab thickness  Direct consideration of other design elements, e.g., –Joint spacing –Load transfer –Shoulder design  Design pavement as a system

12 Overall Course Objectives  Recognize effect of design features on performance  Select appropriate design features  Identify construction practices critical to performance Focus is on jointed plain concrete pavements

13 General Design Considerations Traffic Design Life Subgrade Reliability Climate Costs Other Factors Select Concrete Pavement Type Specific Concrete Pavement Design Elements Subgrade Characterization Drainage Design Base Selection and Design Thickness Design Joint Design Shoulder Design Construction Special Design and Construction Considerations for Reinforced Pavements Concrete Pavement Design and Construction Process

14 Course Content DAY ONE  Course Introduction  Concrete pavement type selection  Subgrade characterization

15 Course Content DAY TWO  Drainage considerations  Base selection and design  Thickness design  Joint design  Shoulder considerations

16 Course Content (cont’d) DAY THREE  Construction considerations  Special considerations for reinforced pavements (optional)

17 Course Format  Lecture/discussion  Workshops  Protocol: –Informal –Questions are encouraged –Class participation is essential

18 Workshops  Opportunity to apply course concepts  Most are computer-oriented: –Selection of k-value –Base and drainage selection –Preliminary thickness design –Final pavement design –Cost-effectiveness evaluation

19 Course Reference Materials  Concrete Pavement Design Details and Construction Practices — Technical Digest  Concrete Pavement Design Details and Construction Practices — Participant’s Workbook

20 Related NHI Courses  Techniques for Pavement Rehabilitation (No )  Portland Cement Concrete Materials (No )  Pavement Subsurface Drainage Design (No )  Construction of Portland Cement Concrete Pavements (No )  Pavement Distress Identification (No )

21 Summary  Comprehensive pavement design –More than just slab thickness –Selection/incorporation of design features  Overview of course –Course content –Format –Reference materials
