PRS-Neoweb™ is an ideal solution for road reconstruction with RAP – Reclaimed Asphalt Pavements. Whereas PRS-Neoweb 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)

PRS-Neoweb 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.

The Neoloy-based PRS-Neoweb also prevents lateral creep, which is a common problem with RAP infill. Unlike HDPE geocells, Neoloy-based PRS-Neoweb is resistant to high temperatures, making PRS-Neoweb suitable for use with hot mix asphalt paving.

PRS-Neoweb 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 PRS-Neoweb “significantly reduced the permanent deformation of the flexible pavement and increased the pavement life by a factor of 10.”

Benefits

  • PRS-Neoweb 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
  • PRS-Neoweb 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 PRS-Neoweb
