CONCRETE PAVEMENT REHABILITATION

Many sections of Tennessee's Interstate System are plain PCCP. Some joints have load transfer dowels and others rely on the aggregate interlock for load transfer. Some sections are 15-20 years old and are in dire need of repair. Although these older sections have faulted badly (1/4" to 3/4" or more), many of them are in good shape structurally. This faulting is becoming more than an annoyance to the traveling public, it could be a contributing factor to the rapid deterioration of the PCCP slabs. Grinding and grooving sections of this PCCP has become a viable solution to this faulting problem. Although grinding and grooving corrects the faulting of PCCP, the type of aggregate used in the PCCP must be considered. Concrete pavement having soft limestone aggregate will polish readily and will probably result in a surface with low skid numbers. If soft limestone aggregate pavements are encountered some other method should be used to improve skid resistance. The purpose of this report is to show some of the techniques and equipment used in grinding, grooving, undersealing, and installing underdrains and joint seals on a two mile section of I-24 just south of I-40 in Nashville, Tennessee. /Author/
