PetraTec surfacing system

PetraDOT

High-performance resurfacing for DOT and heavy vehicle traffic.

PetraDOT is a high-performance cementitious resurfacing system centered on PetraTec HP for transportation infrastructure and heavy-vehicle concrete. It is intended for properly prepared concrete exposed to traffic, deicing chemicals, fuel, freeze-thaw cycling, and demanding exterior service. Substrate condition, repairs, profile, drainage, transitions, traffic control, and return-to-service requirements must be evaluated before installation. Placement thickness, mixing, curing, acceptance testing, and field mockup requirements should be established in the project documents. CST supports customer projects with system guidance, sample or mockup work, installation planning, and ongoing technical support.

Where to consider it

Match the surface to the job.

  • DOT roadways and intersections
  • Bridge decks and approaches
  • Truck lanes and loading areas
  • Transit and airport pavements
  • Parking structures

Substrate

Suitable existing concrete, subject to project assessment. Existing condition and compatibility must be assessed before selection.

System character

  • Designed around DOT and heavy-traffic requirements
  • Reported 8,050 psi compressive strength at 28 days
  • Reported solar reflectance index (SRI) of 47
  • Resistance to deicing chemicals and fuel
  • Freeze-thaw and friction performance

Use conditions, thickness, coverage, preparation, cure and performance requirements must be confirmed in current CST documentation for the selected assembly.

System assembly

Confirm the layers for your project.

Do not select individual layers in isolation. CST confirms the preparation, component compatibility, finish and installation sequence for the job.

  1. Prepared concrete substrate
  2. PetraTec HP high-performance resurfacer

Planning sequence only. A verified layer schedule and application guide must be obtained before installation.

System components
