ELMOD® 7 for Pavement Analysis – Backcalculation and Structural Evaluation

ELMOD® 7 helps engineers evaluate structural pavement layers, perform backcalculation from deflection data, and determine remaining pavement life.

Advanced pavement analysis software based on mechanistic-empirical principles

ELMOD®7 is the industry-leading software program for analyzing pavement structures and performing backcalculation based on deflection data (ex. FWD). Designed for complex engineering projects, it helps teams interpret measurement results, model pavement performance, and plan optimized maintenance strategies. 

The platform enables precise evaluation of pavement layer properties, calculating remaining useful life and required overlay thickness. Additionally, ELMOD®7 features fully supports the new ICAO ACR/PCR classification for airport pavement management.

 

You would use this in projects where: 

  • Analyzing deflection data: Perform advanced backcalculation and apply seasonal adjustments for environmental variations in pavement behavior. 
  • Determining pavement life cycles: Calculate a pavement’s remaining useful life and determine required strengthening or overlay thickness for rehabilitation planning. 
  • Airport & Highway rehabilitation planning: Model pavement structures to support major rehabilitation designs, including compliance with modern standards (e.g. ICAO ACR/PCR for airport pavements).

Still using ELMOD®6?

ELMOD® has supported pavement engineers around the world for decades. As technology, operating systems, and industry requirements evolve, all software generations prior to ELMOD® 7 have now been retired.

You may continue using an existing installation of ELMOD® 6, but Dynatest no longer provides security updates, new licenses, or technical support for software generations earlier than ELMOD® 7.

To secure long-term support, compatibility, and access to future developments, we recommend moving to ELMOD®7.

 

Why Move to ELMOD® 7?

ELMOD®7 is not simply a new version of ELMOD. It is a new software platform built to support the future of pavement evaluation and structural analysis.

Key benefits include:

  • Up to 95% faster analysis through a completely redesigned calculation engine
  • One integrated workspace replacing multiple separate modules
  • Improved analysis accuracy through enhanced FEM, LET, and MET methods
  • Streamlined workflows and modern user experience
  • Built for current and future operating systems, standards, and engineering requirements
  • Ongoing product development, support, and security updates

Ready for the Future?

Join the growing number of pavement engineers and airport authorities using ELMOD®7 as their platform for pavement evaluation, analysis, and reporting.

Bearing capacity classification ACR/PCR module for ELMOD®

Since 1981, it has been mandatory to report on the bearing capacity for airports using the ACN/PCN classification prescribed by the International Civil Aviation Organization (ICAO).In November 2024 ICAO introduced a new classification ACR/ PCR.

  • ACR stands for – Aircraft Classification Rating and tells how different aircraft affect pavements.
  • PCR stands for – Pavement Classification Rating and shows how much weight the pavement can carry.

By using this new ACR-PCR classification, airports can improve their operations, enhance safety, and plan better pavement maintenance.

The Dynatest ACR/PCR module is implemented in ELMOD® 7.
