COLD ASPHALT
A direct replacement for hot asphalt AC20 and AC32 made from road planings and other recycled aggregates with bitumen emulsion.
A top quality material made to last.
Order40% less CO2 than hot material.
100% recycled aggregate.
95% less particulate matter and volatile organic compounds emitted.
Flexibility, workability, self healing, slow curing.
Can be stored on site so logistical advantages too.
Also known as 948 Road Base and Binder or ex-situ cold recycled bound material.
Specification for Highways Work (Series 900 CL. 948) TRL PPR666.
Granite or limestone road planings, recycled fines.
CE marked bitumen emulsion.
Grading: optimum strength. 0-20mm Zone A and G1
Computerised mixing: moisture content, binder %, audit trail.
External lab validation: of mix designs and from production mixes (ITSM and wheel tracking)
A direct replacement for hot AC32 and AC20 road base and binder.
No redesign is needed to layer thicknesses.
Can be used as a surface course subject to surface dressing or micro asphalt.
A B1 or B2 material with an indirect tensile stiffness modulus of 1,900-2,500 MPa.
The material can be rapid or normal curing (Quick Visco-Elastic or Slow Visco-Elastic).
Recycled aggregates are crushed to size 0-20mm.
Bitumen emulsion is added.
The product is thoroughly mixed in a computer controlled batching plant.
The plant can mix 200 tonnes per hour.
Collect from the plant in Sussex or book a delivery by tipper.
Material can be laid by rake, excavator or asphalt paver.
It’s always compacted by roller.
It can be trafficked or overlaid in 2-24 hours (initial curing time).
The material has a shelf life of several days.
