Neoloy® Geocells Utilize Recycled Asphalt as Base Course

Neoloy Geocells are a solution for road reconstruction with Reclaimed Asphalt Pavements. Reclaimed asphalt can be used as a base course with a thin overlay.

Neoloy Geocells are an ideal solution for road reconstruction with RAP – Reclaimed Asphalt Pavements. Whereas Neoloy 3D confinement improves the performance of recycled materials, on-site reclaimed asphalt can be used as a base course with a new thin overlay. The economic and environmental value for road rehabilitation are evident.(See case study)

Neoloy increases RAP stiffness making additional processing (remixing binder and aggregate) unnecessary. This saves energy, hauling and costs. The Modulus Improvement Factor (MIF) of PRS-Neoweb strengthens the RAP base infill such that it approaches the structural value of asphalt itself

Neoloy Geocells also prevent lateral creep, which is a common problem with RAP infill. Unlike HDPE geocells, Neoloy is resistant to high temperatures, making Neoloy Geocells suitable for use with hot mix asphalt paving.

Neoloy also reduces the total amount of asphalt and RAP in a pavement to reduce the pavement thickness. Extensive Testing by the MATC (Mid-America Transportation Center – Prof. Jie Han) has demonstrated that Neoloy Geocells “significantly reduced the permanent deformation of the flexible pavement and increased the pavement life by a factor of 10.”

Benefits

  • Neoloy reinforced base acts as a semi-rigid foundation
  • Increases stiffness and reduces compression of base course
  • Reduces the bituminous asphalt concrete of pavements up to 25%
  • Enables a 50% or more reduction in the thickness of base course layers
  • Increases bearing capacity by a factor of 2-3x
  • Confinement reduces creep and improves the modulus of RAP infill
  • Neoloy Geocells can utilize a wide range of milled RAP grade size, including poorly graded materials
  • Enables on-site recycling of asphalt pavement
  • Reduces structural pavement layer thickness
  • Reduces construction time and costs
  • Permits shallow instead of full depth rehabilitation
  • Reduces maintenance cycles and life-cycle costs
  • Sustainable solution for on-site recycling
  • Eliminates the need for processing RAP
  • Reduces hauling, energy and aggregate
  • Recycled crushed concrete and masonry rubble are also excellent infills for Neoloy Geocells
