Stringless Paving at Baton Rouge

This article describes how stringless paving was used in a runway project at the Baton Rouge Metropolitan Airport in Louisiana. The contractor was required to remove and replace a 1,146 m concrete runway and to furnish and place a new 152 mm thick cement-treated base. The contractor's trimming/placing equipment was equipped with the stringless system. A model of the job site was created from the project design data and the information was put into the system's computer. The same model of the surface was used for both the trimming of the cement-treated base and paving the concrete. Front and rear slope sensors on the paver were used to measure the paver's position and any cross slope in the slab. Prisms were also mounted on the paver and were used for tracking purposes for the total stations on the project. Three stations were at work on the project: two constantly took shots at the prisms on the paver and relayed those measurements back to the computers, which was interfaced with the paver's control system, while the third was used to conduct as-built checks of the line and levels of the new runway. The stringless system saved the contractor significant time in setting stringline and met airport pavement tolerances.
