Trimble 2D Paving Application and Solution
Trimble PCS400 - Applications • Typical: Roads and Commercial Surfaces
Control Box (CB440/CD620) • Provides smooth chatter-free operation • Large, easy-to-operate display with bright lightbars and split screen option • One man can easily control both sides of the screed
Best sensors in the business • AS200 Slope Sensor • Tested 100% better in accuracy than Topcon’s • Excellent stability (no drifting) compared to Topcon’s • ST200 Sonic Tracer • No costly maintenance like the foil based units • No bail that gets bent or lost • Easy stringline or curb tracking
Sonic Averaging Beam • Average surface over 3 Sonic Sensors with 15 transducers • Provides paver freedom of movement without mechanical averaging skis • Has proven to achieve Final Lift specs and make 100% bonus
Trimble 3D Paving Applications and Solution
Trimble PCS900 3D Paving *AS200 SNR2420 *ST200 + CB460 AS450 MT900 *CB440 Single Or Dual
3D Paving - What issue do we solve? • Project Issue: Lay material where there is no reference surface • Benefit 3D Paving: Eliminate the stringlines! Large surfaces Base material
What issue do we solve? • Project Issue: Lay complex designs • E.g. Transitions, super-elevated curves, variable drainage angles, … • Benefit 3D Paving: Screed grade and slope automatically adjusted to design Variable drainage angles Elevated Curves Guide Policy for Geometric Design of Freeways and Expressways - NAASRA 1976
What issue do we solve? • Customer Issue: Take out long longitudinal roadwaves • Benefit 3D Paving: • Ability to improve smoothness without stakes
Why can 3D smooth longitudinal roadwaves better then traditional 30 feet averaging beam system? Original Surface with longitudinal roadwaves Surface after paving with a traditional averaging beam system Surface after rolling: roadwaves not entirely gone yet
Why can 3D smooth longitudinal roadwaves better then traditional 30 feet averaging beam system? Original Surface with longitudinal roadwaves 3D Paved surface before compaction New road design with compaction factor (e.g.1.25) 3D Paved surface after compaction
Trimble PCS900 - Applications • Variable depth and slope paving for airports, roads and commercial surfaces • Both base material and asphalt
Trimble PCS900 – Other Applications • Tunnels
Trimble PCS900 – Other Applications • Sports surfaces Running tracks Tenniscourts
Trimble PCS900 – Other Applications Small parking lot PCS900 provides accuracy and flexibility for commercial contractors
Trimble PCS900 – Other Applications • Cement Treated Base - Advantages 3D Paving • Normally no grade references • Maximizing thickness can save more expensive asphalt material • And use Trimble CCS900 UTS Grade Control when layer thickness does exceed spec, in this time critical compaction operation
Trimble PCS900 – Other Applications • Roller Compacted Concrete- Advantages 3D Paving • Final surface for industrial terrains • Same advantages as for Cement Treated Base
Trimble PCS900 Customer Experience
THE PROJECT: New Airport Runway Western USA Runway: 9300' Runway Width: 150' Paving Width: 15' Thickness: 2x 2" lifts 12 hrs/day for 15 days Production Paver with Trimble PCS400+PCS900
THE PCS900 EQUIPMENT MT900 Adjustable Mast (x2) SNR2410 CB430 CB440 (x2) AS200 AS450 (x2) ST200
THE OPERATION: New Airport Runway Western USA 4 SPS930, leapfrogged in pairs by stake person Regular grade checking behind the paver Uncompacted designs created in BC-HCE 1st Level Controls Max UTS distance 150-200m
THE RESULTS – SMOOTHNESS • New Airport Runway Western USA • Average profile index of the 160 0.1mile sections: 0.21 inch/mile • Compare: FAA 100% pay factor up to 7 inch/mile • Only 2 out of 160 profile index values above 2 inch/mile • No bumps and dips detected • 100% pay factor for the whole job
THE RESULTS – ACCURACY • New Airport Runway Western USA • Only 2 out of 2611 points measured did not comply to the FAA accuracy requirement • The average deviations from design for all runway lanes are: • Mean -0.003’ • Standard Deviation 0.015’
THE RESULTS – SAVINGS New Airport Runway Western USA Trimble estimated savings
