Abstract:

The surface transportation system forms the biggest infrastructure investment in the United States of which the

roadway pavement forms an integral part. Maintaining the roadways can involve rehabilitation in the form of

widening; which require a longitudinal joint between the existing and new pavement sections to accommodate the

wider travel lanes, additional travel lanes or modification to shoulder widths. Several methods are utilized for the

joint construction between the existing and new pavement sections; vertical, tapered and stepped joints. The main

purpose of this research is to develop a formal recommendation as to the preferred joint construction method that

provides better pavement support in the State of Wyoming. Field data collection of Dynamic Cone Penetrometer

(DCP), Falling Weight Deflectometer (FWD), base samples for gradation and moisture content were conducted on 28

existing and 4 newly constructed widening projects. Survey of practices and preferences of other states, and

constructability issues were undertaken. Costs of each joint type were compared as well.

Results of the analysis indicate that the tapered joint technique showed relatively better pavement strength compared

to the vertical joint type, and could be the preferred joint construction method. The vertical joint has an 18% increase

in cost compared to the tapered joint. This research is intended to provide information and/or recommendation to

state policy makers as to which of the base widening joint techniques (vertical, tapered, stepped) for flexible

pavement provides better pavement performance.
