Superbase™

This asphalt product is a specifically engineered asphaltic concrete 14mm dense binder course mixture and has been designed to fill the gap within the range of binder course materials described in UK asphalt standards.

The omission a dedicated AC14 binder course within UK standards often leads to inappropriate use of BSEN standard binder course mixtures eg AC20 Dense binder, particularly when laid in relatively thin layers. Superbase can be laid down to 40mm thick and still provide a very dense, impermeable and durable binder course layer whilst still maintaining high levels of resistance to permanent deformation making it applicable for high and low levels of traffic.

Key benefits 

  • Suitable for use in either low or high density traffic situations
  • Equivalent stiffness modulus to a conventional HDM 50 or HMB 35 for Superbase grades 50 or 35 respectively
  • Developed to provide the function of a durable and impermeable supporting layer below modern thin surfacing’s
  • Relatively rich binder contents and low insitu void contents; designed to be 6% or less rendering them impermeable
  • Uniform mat with low risk of segregation

Applications 

  • Motorways
  • Trunk Roads
  • LA highway network
  • Commercial/ Industrial
