| 摘要： | Research has been undertaken into engineering properties of roller compacted concretes containing fluidized bed combustion/pulverized coal combustion (FBC/PCC) by-products as well as FBC/PCC-Portland Cement concrete mixtures prepared using conventional placement technique. This laboratory effort has resulted in identification of a number of potentially viable commercial applications for the FBC by-products residues derived from Illinois high-sulfur coal. One potential and promising application of the FBC/PCC solid waste residues, which also accounts for the large utilization of coal-based by-product materials, is in pavement construction. The proposal presented herein is intended to embark into a new endeavor in order to bring the commercialization aspect of the initial laboratory project a step closer to reality by conducting a field demonstration of the optimized mixtures identified during the two-year laboratory investigation. A total of twenty-three different pavement slabs will be constructed at an identified site located in the Illinois Coal Development Park, Carterville, Illinois, by two construction contractors who are part of the industrial participants of the initial project and have expressed interest in the construction of experimental slabs. Both conventional and roller compacted concrete placement techniques will be utilized. All sections will be subjected to an extensive engineering evaluation and will be monitored for nearly a year for both short and long-term performance. The field results will be compared to that of the equivalent laboratory-prepared mixes in order to ascertain the suitability, of the proposed mixes for field application. During this reporting period, the physico-chemical and preconditioning characteristics of the raw materials were evaluated. Construction of the experimental road consisting of twenty-three surface and base course slab sections was also completed. |
