Neoloy® Tough-Cells Utilize Recycled Asphalt as Base Course
Neoloy Tough-Cells are a solution for road reconstruction with Reclaimed Asphalt Pavements. Reclaimed asphalt can be used as a base course with a thin overlay.
Neoloy Tough-Cells 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-Neoloy strengthens the RAP base infill such that it approaches the structural value of asphalt itself
Neoloy Tough-Cells also prevent lateral creep, which is a common problem with RAP infill. Unlike HDPE Soft-Cells, Neoloy is resistant to high temperatures, making Neoloy Tough-Cells 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 Tough-Cells “significantly reduced the permanent deformation of the flexible pavement and increased the pavement life by a factor of 10.”
