ALIZE LCPC

Software for pavement structures analysis and design

ALIZE-LCPC is the professional software for the mechanical analysis and design of pavement structures. First-line of ALIZE-LCPC is to integrate a rational method. It means that we do not calculate the structure a given service life but rather estimate the evolution over time in terms of cumulative probability of failure. This design method is used in France for many years and is widely spread in Africa, Spain or eastern European countries. As ALIZE-LCPC integrates a rich database of materials (rubber, treated, concrete…), it allows the analysis of a wide range of projects.

 

FEATURES

Mecanical analysis

ALIZE-LCPC software integrates the Burmister’s algorithm. Thus ALIZE-LCPC computes any stress or strain at every point or depth of the multi-layered structure.
Features:

  • Definition of a multi-layered structure
  • Definition of the layers interface behaviour (bond, slip or semi-slip)
  • Definition of the material inside the layers from the integrated database or from user’s properties.
  • Definition of loads (axles or not) complex or not.

French administration method

ALIZE-LCPC initial goal was to spread the French administration method and standards for pavement structures design. Thus it integrates all the coefficients for the rational method: risk, aggressiveness, standardized materials, damage laws and the reference load (13t / axle)
A dedicated calculator guides the user for the definition of admissible values for the design of standard pavement structures.

Frost-thaw analysis

ALIZE-LCPC integrates an option for the frost-thaw analysis of the structure.
The thermal propagation is calculated in the pavement structure. Parameters for evaluation of the frost sensibility of the subgrade layers are proposed.
Thus the pavement engineer can evaluate the sustainability of the structure during winter season. A good design of the pavement structure could avoid the traffic interruption.

Regional parameters

ALIZE-LCPC is designed for an easy parametric study on several parameters.
Thus any user can edit:

  • The reference temperature,
  • The materials library,
  • The design parameters (aggressiveness, risk…).
      These options allow any user to adapt the software to its local context, for example in regions such as Sub-Saharan Africa and the Maghreb.

APPLICATIONS

FOR NEW ROAD PROJECTS

Data base of various vehicles and possibility to create new vehicles and save them to the library.


FOR PAVEMENT STRENGTHENING

Because roads are getting old and heavily used, their structure may not support the actual traffic. The initial materials are cracked or overworked. In this scope of expertise, ALIZE-LCPC software helps the pavement engineer to estimate the behavior and to propose reinforcements.  Hence, ALIZE-LCPC integrates a back-calculation option for the analysis of deflection basins measured with Falling Weight Deflectometer, Benkelman’s beam or other deflection measurement devices. The damage analysis is also possible with ALIZE-LCPC. Thus the engineer can evaluate the theoretical degradation evaluation of the road.


FOR AIRFIELD PAVEMENTS

A robust solution with comprehensive data base of various air crafts. Automatic optimisation of pavement thickness. 


FOR PORT & LOGISTIC PLATFORMS

The software ALIZE-LCPC is the perfect tool for the design and analysis of harbour and logistic platforms. Any type of carriage machine (reachstackers) or lorries can be generated with accurate print and weights. Their mechanical influence on the pavement structure is analysed in damage (Miner’s law). Thus pavement structures engineer or harbour facilities manager can build the pavement suitable for the sustainable and long term use of the facility.
