Rigid Pavement Design. Contraction Joint Spacing.

摘要

A study was made of the effect on riding quality of variation in contraction joint spacing and in skew angle of joints to the centerline on a section of Interstate 10in Santa Rosa County (West Florida). Nine sections,each one half mile in length,were constructed in 1967,and included sections with standard 20-foot spacing,with two types of irregular spacing,with perpendicular transverse joints,and with a skew of approximately 2feet in 12feet. The study extended over a period of seven and one half years from completion of construction in June 1967.
