SpectraPave3

SpectraPave3, developed by Tensar International Corporation, is a pavement design and analysis application that helps engineers evaluate the benefits of incorporating Tensar geogrids into unpaved and paved roadway sections, working platforms, and similar aggregate-based structures. The software streamlines comparison of reinforced versus unreinforced designs, enabling users to optimize aggregate thickness, estimate traffic capacity and service life, and document potential cost and schedule savings.

Key capabilities include:

• Rapid scenario modeling to compare design alternatives with and without geogrid reinforcement
• Input of site-specific conditions such as subgrade strength, traffic/loading, and material properties
• Recommendations for layer thicknesses and configurations tailored to project objectives
• Quantitative outputs that support design justification, budgeting, and stakeholder communication
• Clear, exportable reports that summarize assumptions, calculations, and results

SpectraPave3 is intended for civil and geotechnical engineers, pavement designers, and contractors seeking to improve performance, reduce risk, and achieve more efficient aggregate utilization through geogrid reinforcement.

SpectraPave3 is developed by Tensar International Corporation. The most popular versions of this product among our users are: 1.0 and 3.4. The name of the program executable file is Spectra3n.exe.
