Elmod^® 6 forms the core module of the Dynatest^® suite of analytical programs including:
The FEM / LET / MET module, LCCA module and PCN module

ELMOD^® is an acronym for Evaluation of Layer Moduli and Overlay Design.

Many current methods of pavement evaluation and rehabilitation design rely almost exclusively on empirical relationships. Since empirical rules are difficult to generalise across a wide range of pavement types, loading and local environmental conditions, a primary goal for the Dynatest^® methodology has been to reduce the reliance on empirical approaches. Instead, pavements can be analysed like most other civil engineering structures, i.e., through the use of calculated and allowable stresses and strains at critical points within the pavement structure, under load, the relationships between allowable stresses and strains, and pavement distress, remains essentially empirical. The calculation of existing stresses and strains within the pavement structure can be accomplished through an analytical or mechanistic approach.

The Elmod^® 6 Core module has now been expanded to include a design sub-module for the design of new pavements and rehabilitations for existing pavements based on any number of existing layers.

Elmod^® 6 has been redesign to make things simpler and more user friendly

• Operates in a Windows^® Vista^®, XP^® and 2000 environment.
• The menus have been restructured to a more logical format with icons and click free navigation
• The user interfaces have been redesigned with greater functionality. Graphical interfaces are provided to facilitate input and modifications to input data. 
• Accomodates up to 15 geophones.
• Batch processes FWD/HWD data files.
• Accomodates point related structural information, such as output from GPR measurements.

The Parameter Setup has been reorganized to provide a more logical interface.

• Criteria can be selected from a pre-defined list
• Criteria, temperature correction functions, and seasonal variations can be viewed graphically
• The setup of design loads is easier and more flexible

• Better guidance is provided for temperature/modulus corrections
• Calculation and plotting of moduli under user-specified reference conditions has been included
• All traffic related information has moved to the design window.
• It is now possible to design based on existing unbound layers or subgrade.
• It is now possible to design new pavement structures with an option for using Monte Carlo Simulation
• The creation and management of design loads is now easier and more flexible
