The stringless system has several advantages. It can accommodate radii or superelevations automatically according to design data. The real-time navigation system allows the project data created in the CAD system to be directly put into the paving process. The result is improved product quality, operational safety and work rate. Other advantages include uninterrupted control of the machine over long distances.
Contractors have free choice of positioning for the total stations.
There is no stringline installation or maintenance. The number one advantage is going to be the job site logistics. With time, I think it's going to be a little more accurate and give a better performance than what a stringline job would. That's one of the major selling points of the system. Some firsts in the concrete paving industry have been accomplished along the way.
