Relating Ride Quality and Structural Adequacy for Pavement Rehabilitation and Management Decisions (Techbrief)

 General Interest: provides practical guidance to engineers responsible for the day-to-day design, construction, rehabilitation, maintenance, and management of pavements. Research/Reference: useful for researchers doing further work in the pavement area as well as those developing improved testing and design procedures. Includes documents of historical value.

Primary Topic: Pavement Rehabilitation

Description: This TechBrief discusses the relationship between pavement ride quality and structural adequacy. It presents highlights from a literature search and findings from the analysis and comparison of ride quality and structural adequacy data from the Long-Term Pavement Performance (LTPP) program. Although a viable relationship between the two parameters could not be established, the lack of correlation is considered of value to pavement management system (PMS) practitioners, as it indicates that good ride quality does not mean good structural support or vice-versa. This becomes an important consideration for those who want to base performance measures on ride quality indicators.
