Neoloy® Tough-Cell Highway Reinforcement or Low creep and High Stiffness

PRS Neoloy® Tough-Cells highway stabilization solutions deliver strength and increase the lifecycle of highway construction projects

Neoloy optimizes the use of geocells in highway engineering (See Geotechnical Engineering Overview) for engineers and contractors by providing design assistance as well as by a choice of categories of geocells customized to project requirements. The result? Increased performance at lower cost, no matter the project type.

  • Validated design methods – integrating the Neoloy Tough-Cell modulus improvement factor (MIF) for use in unpaved roads (Giroud and Han method) and highway construction (layered elastic model method)
  • New specifications and standards – performance-based specs that more accurately reflect the performance of geocells in the field than conventional specifications.
  • Engineering consulting – PRS provides geotechnical engineering and design services to maximize the impact of Neoloy Tough-Cells on each highway reinforcement project.
  • New Neoloy categories – PRS developed 4 main types of geocells to optimize a project (and cost-effectiveness) by matching the tensile strength and durability of Neoloy Tough-Cells to the project requirements.
