Protection from the elements until the next phase

A pavement is only as good as its foundation-base. Traditionally, road bases have been prepared for surfacing with prime coats to protect the granular base during construction and help reduce dust. Prime seals provide a good bond between the underlying base and hot mix asphalt overlays. On low volume roads, they bond the base to spray seals or other thin surfaces, which might otherwise delaminate. As traffic increases these treatments serve well as foundations for staged construction of future overlays.

In the past most primes were made from cutback asphalts or other petroleum based materials that were slow to come and emit volatile organic compounds. Some of these materials also had poor penetration into compact bases, thereby reducing their bonding effectiveness. Worse still there have also been incidents where run-off from these materials has polluted the soil and even nearby streams.

EcoPrime is an eco-friendly, solvent-less prime

It contains no petroleum solvents that have flammable vapours, are hazardous to workers and release harmful VOC’s into the environment. It is made from sustainable natural resources that do not pollute the waterways. It is water based, safe for workers, and easy to use.

The innovative Colas WA technology is engineered to give superior penetration into the base, binding surface fines and superior bonding between the underlying surface and overlays. EcoPrime also serves and excellent dust control taking the particles out of the air we breath.

Engineering solutions that work- A superior prime and dust suppressant  

The economical treatment can be used as a soil stabiliser and dust suppressant. Ad a prime it protects the underlying layers from wet weather by providing a temporary waterproofing layer. It can also be used to reduce soil erosion on ditch banks and shoulders.  It does not harm vegetation

Pavement engineers are struggling with increasing traffic and loads, dwindling funds and rising material costs. Increasing capacity is an important part of maintaining an effective road infrastructure. Colas Solutions and the family of Colas companies believe in designing solutions that provide long lasting pavements that are built right the first time, whilst minimising effects on the environment and health. EcoPrime is just one of those solutions engineered to give excellent performance during and after construction.

EcoPrime Benefits

EcoPrime accounts for just a small fraction of the total project cost, but it makes a big contribution to the overall project success. Just some of the advantages of EcoPrime include:

  • Solvent-less
  • No flammable or harmful volatiles
  • Easily diluted in water
  • Made from renewable resources
  • Superior penetration into all types of compacted base materials
  • Excellent dust control
  • Toughens the base surface to prevent damage from construction equipment
  • Protects the base from moisture
  • Coats and bonds loose material on the surface of the base
  • Provides excellent adhesion between the base and the succeeding course
  • Less expensive

The EcoPrime residue not only suppresses the dust layer, but it binds the dust into a thin membrane that protects the surface

EcoPrime has none of the drawbacks of conventional prime coats and dust suppressants as it does not:

  • Pollute soil and ground water
  • Harm vegetation
  • Replace one atmospheric pollutant (dust) with another (VOC’s)
  • Cause a fire hazard
  • Cost more
