PERFORMANCE OF LOAD-TRANSFER DEVICES. SIXTH INTERIM REPORT
The study reported is part of a large effort to examine various design aspects of rigid pavements in New York. It involves the performance of several types of load-transfer devices (LTDs) for transverse joints. When corrosion and structural deterioration of then-standard LTDs became apparent in the early 1970s, plastic-coated dowels were tried. Soon, epoxy-coated I-beams were put into use and a trial installation of fiberglass dowels was completed. Earliest installations of these devices have since been monitored to determine whether their performance was an improvement. After 10 to 14 years, horizontal and vertical movements along with faulting measurements indicate they are providing better load transfer across transverse joints. In addition, lab pull-out tests and observations of LTDs removed from pavements show no corrosion or other deterioration that would have caused loss of load transfer or abnormal pavement stress.
