CSCGA (Cement Stabilised Coarse Graded Aggregate)


Cement Stabilised Coarse Graded Aggregate (CSCGA) is used as part of a permeable pavement design. This material can be used in addition or in place of coarse graded aggregate and asphalt in some permeable pavements.

 Benefits
 

  • Ability to resist increased traffic loadings
     
  • Potential to replace asphalt in the pavement build up
     
  • Is already permeable so unlike asphalt (DBM) it requires no coring/puncturing
     
  • Reduced cost compared to asphalt
     
  • Low density (roughly 1.8t/m³)
     
  • Requires no specialist paving techniques

 Specification


CSCGA is produced to BS EN 14227-1:2013, with the following specification requirements:
 

  • Minimum cement content = 3%
     
  • Strength Class = C5/6
     
  • Minimum permeability = 20,000 mm/hour
