Repair of Thermally Cracked Bituminous Pavements with Fiber Reinforced Plastic Composites
The apparatus under development in this project is a structural component or beam fabricated from a fiber reinforced composite (FRPC). The FRPC beam is a structural repair component intended to bridge a deteriorated thermal crack in full depth bituminous pavements or partial depth bituminous pavements over portland cement concrete. The bridging action provided by the FRPC beam is intended to minimize roughness through the repaired area for up to five years, eliminate reappearance of the deteriorated crack, and provide a controlled expansion crack that can be treated with standard sealing techiques. The apparatus is designed for maintenance use as a field expedient, semi-permanent repair using tools that are commonly available at the Area Maintenance level. Three FRPC beams were constructed for field trial in a thermally cracked, fully bituminous pavement on US-36 east of Hiawatha, Kansas. Each of the beams were instrumeted with bonded metal foil strain gages and field installation by KDOT maintenance forces was done in August and September of 1997. The FRPC beams have been evaluated since intallation and this evaluation will continue for up to five years from the date of installation. Evaluation of the beams has been accomplished through static load tests using the stain gage instrumentation and Falling Weight Deflectometer measurements. The FRPC beams have performed satisfactorily as of the date of writing.
