Abstract:

Researchers analyzed the structural responses of CRCP using three-dimensional finite element modeling (3D-FEM) in Ansys at the depth of the longitudinal steel at transverse crack areas with various steel designs which, if excessive, could cause horizontal cracks. The output was used in selecting the steel designs that will be employed at the experimental sections. Subsequently, the researchers investigated the CRCP behaviors affected by various steel designs in the field. Four (4) test sites were identified, namely: IH35 in Waxahachie, US62/180 in El Paso, IH10 in Converse and IH35 in Hillsboro. Mid-depth, upper-depth and upper-depth low CoTE test sections were investigated in El Paso while only the first two sections were investigated in Waxahachie, Converse, and Hillsboro. Sensors were installed accordingly such as steel strain gages (SSG), 2- and 6-inch vibrating wires strain gages (VWSG), and thermocouples along the induced crack location of the slab. In addition, researchers also installed REBEL sensors, which are gages that provide real-time information of the elastic modulus development of concrete, in IH35 in Hillsboro.
