Application
Mix-in
  • Rip the road to 150 mm and break large clods to maximum 50 mm
  • Calculate the approximate volume of water required to reach OMC and add 85% of the required product application rate to this quantity of water
  • Apply the solution onto the prepared surface in 2 to 4 applications, mixing thoroughly between applications
  • Shape to required camber and compact with pneumatic or vibratory roller to required density
  • Apply remaining 15% product to the road surface while still damp
Spray-on
  • For spray-on applications, the road surface should be well compacted, density >93%, firm and free of excess loose material and with sufficient camber to allow for proper drainage
