Austin Bridge & Road Paving the 1st Formula One Purpose Track in the United States The 1st Formula One Track in the World to be 3D Paved In this session, we will present how a contractor has managed to outperform the demanding specifications of the first purpose-built Formula 1 track in the USA using three 3D paving systems. The F1 track represented a highly complex design while prescribing tight elevation and smoothness specifications. This session is intended for the owners, projects managers, surveyors, site supervisors, foremen and operators of general and paving contractors Matthew Hollensworth – Cody Lowery – Mike Ellingson

COTA Project Data Basic Track Project Data Survey scope all of the complex

Quantities 80,000 tons of flex base placed with 3D paver & 50,000 tons of asphalt base paved with 3D Paver. Remaining course of asphalt placed with averaging beams.

The Layers of the Track Note the 14 Different layers of the Track.

3D Asphalt Paving

Our Strategy to 3D Paving Research available 3D paving products Decide the best fit for our company’s needs Develop procedures and processes for our new paving system (including evaluating, training, and adding the right personnel) Getting the buy in from Dr. Hart Testing, trusting, and trying our new equipment Exceling with our new product What was our strategy at Austin to over come the task at hand?

Current Platform Our Current Platform allows us to use our machine control the way we see fit. If we want it on a Dozer one day then a paver the next we have that ability using the Trimble GCS and PCS Platform.

Interchangeable Components Robotic Total Station CB460 3D Control Box TSC3 Data Collector The Right Grade Control Equipment Being able to Interchange components was on of our reason for going with the Trimble Systems on this project. Also our current capital investment was another reason.

Intelligent Repairs Working w/ Design Changes Through the course of the project we received many design changes and some after we have already paved an area. This slide shows us using 3D Milling to shave a area down to better transition the curve.

All in one day – All at the same time One of the first jobs to have 3D milling, robotic base and asphalt paving, Robotic topo collecting with roller along with robotic and GPS grading an not to mention the tremendous amount of survey that was happening in the back ground.

How Did We Do? Outstanding safety performance Met financial objectives Opportunity “Track is awesome”, Dr. Rainer Hart “One of the top two tracks in the world”, Tilke Eng. “Love it”, Mario Andretti “Highest Rating”, Fédération Internationale de l'Automobile (FIA) “Greatest racetrack on the planet”, The Tom Byrum

Learning Curves Control is Critical Modeling Methods Training Techniques 3D Paving is NOT a grading tool (Sub-Grade is important) 3D Equipment is still limited to the capabilities of the paving machine (roller were added to tow arms to prevent binding) Having an Extra Data collector made all the difference
