Achieving A High Level of Smoothness in Concrete Pavements Without Sacrificing Long-Term Performance

CHAPTER 8. RECOMMENDATIONS AND GUIDELINES

This chapter presents recommendations and guidelines for design features, PCC material properties, and construction procedures for constructing pavements having high initial smoothness while ensuring good long-term performance. Recommendations and guidelines for smoothness testing and use of profile data to troubleshoot problems are also presented in this chapter.

VALUE OF BUILDING SMOOTH PAVEMENTS

The roughness progression plots for JPC pavements in the LTPP program showed a parallel pattern in roughness progression. This finding indicates that pavements that are built smoother will provide a longer service life. These pavements will also provide road users with a better ride quality.
