 Tensar SpectraPave4-PRO Software

Optimizing Paved Roads, and Stabilizing Unpaved Roads and Construction Platforms

SpectraPave4-PRO™ Software (SP4-PRO) is a road construction software that provides pavement design engineers the most powerful tool available for evaluating design options and optimizing pavement performance using Tensar® Geogrids. Developed for Tensar International’s Spectra® Roadway Improvement System, SP4-PRO enables users to:

  • Design for a specific level of performance
  • Analyze a variety of support and loading conditions and serviceability limits
  • Evaluate and compare designs and costs for both unbound aggregate and mechanically stabilized aggregate layers (MSL)

SP4-PRO is a comprehensive, systems-based pavement design software suite that offers the full benefits of Tensar's knowledge and experience in analyzing both subgrade stabilization and pavement optimization applications. These applications incorporate Tensar® TriAx® TX5 and TX7 Geogrids, key components of the Spectra System. This engineering software is available at no charge. It is recommended for users to attend a free training module delivered by a Tensar specialist.
