The Kentucky Transportation Center was requested by Mr. Tom Brock, Vice President of McWhorter and Company, Inc., to examine cores obtained from a PCC floor slab of a Lowe's store in Bowling Green, Kentucky. From a telephone conversation with Mr. Brock, is was our understanding that a large portion of the surface of the floor slab was scaling and becoming detached. This apparently involved approximately the top 118 inch of the slab.
Nine cores were delivered to our laboratories. They were obtained at the locations shown in the floor map included in Appendix A. Those nine cores are shown in Figure No. 1, which also illustrates their relative thicknesses.
