Each existing 25’ square panel (15” thick) on Bravo was replaced by two 25’ x 12.5’ x 13” thick slabs. Each existing 20’ x 25’ panel (15” thick) on Yankee was replaced by two 20’ x 12.5’ x 13” thick slabs. All slabs were interlocked with standard load transfer dowels. The slabs were intentionally warped to match the surface of the surrounding pavement. The project was completed in three nights, with each closure beginning at 10:00 pm and lasting for 15.5 hours, 9.5 hours and 8.5 hours respectively. On the third night of installation, the grading of the bedding material and placement of the four slabs was accomplished in 2.2 hours. The new slabs were opened to airport traffic before grout was installed. Grouting was completed on two subsequent evening closures.
