Title: Mechanical Behavior of Ultrathin Whitetopping with High-Strength Fiber-Reinforced Concrete Panel
Accession Number: 01076748
Record Type: Component
Availability: Transportation Research Board Business Office 500 Fifth Street, NW Abstract: This paper deals with dynamic behaviors of a whitetopping structure with high strength fiber reinforced concrete panel as the top layer (HSC-WT) under traffic load. A test pavement of HSC-WT was constructed on an accelerated loading facility and was subject to moving axle loads. After two hundred thousand axle passes, although small gaps developed between HSC panels and grout near joints, any severe cracks didn't develop. Based on analysis of the loading test with dynamic 3DFEM and comparison of the computed results with the measured data, visco-elastic parameters of the asphalt layer were identified. Stress analysis using the identified visco-elastic parameters confirmed that the stresses in the panel due to axle load are much less than the strength of the HSC panel, if the panel and the grout is fully bonded with each other at the interface.
