Asphalt reinforcement
Asphalt surfacing provides a durable, low-noise, permeable road surface but unfortunately it can be prone to cracking and wear due to external forces including traffic load, movement of the subgrade material and seasonal temperature fluctuations. The cracking and wear of the surface has an impact on ride comfort and safety, with the maintenance required adding significantly to whole life costs and carbon footprint.
Asphalt reinforcement is proven to extend fatigue life and increase the maintenance intervals of asphalt pavements.
Asphalt reinforcement works in three distinct ways. First, it reinforces asphalt by giving it the tensile strength needed to significantly delay the occurrence of cracks and maintain granular interlock after cracking has occurred.
Secondly, it reduces the effect of stress and prevents reflective cracks from propagating up from the high stresses at the bottom of the pavement or down from the surface.
Last but not least, it works as an impermeable barrier within the asphalt layer that directs the flow of rainwater to the road edge drainage, preventing infiltration into the subbase and the resultant freeze/thaw damage, loss of bearing capacity and pothole development.
Reflective cracking of the base layer induced by thermal effects will be reduced by using Enkagrid or Enka-Tex for asphalt reinforcement.
The cracking and wear of the surface caused by bending and shear has impacts on ride comfort and safety. Enkagrid contributes to lowering the maintenance cost of highways and roads by reducing these effects.
