A new pavement design software, which is the only one able to optimize the slabs sizes less than 10ft, has been launched recently. OptiPave2^TM software is specifically tailored to design short-jointed concrete pavements for any set of climate, traffic, subgrade/subbase layer, and material property inputs including the addition of macro-fibers.. The software calculates stresses, using a neural network system developed on runs of Islab2000^TM. It is based on the fatigue damage equations of the project NCHRP 1-37° (NCHRP 2006), joint faulting using the energy differential model and IRI. This mechanical-empirical design software was calibrated using full scale test sections and a study conducted on the University of Illinois . TCP designs include unbonded concrete pavement over granular or stabilized base layers. Typical slab sizes for TCP are between 4.5 ft to 8 ft long by 6 ft wide with slab thickness ranging from 60 mm to 250 mm depending on traffic, climate, and soil conditions. Some of is features are:

o Either it calculate the thickness or evaluate the distress of a given structure

o Traffic analysis by Load Spectra or Equivalent Axles

o Up to six supporting layers characterization

o It allows the user to design plain or fiber reinforced concrete pavements.

o Two Units System (English and metric) and multi-language

·         It computes:

o    It computes Three types of cracking (Transversal, Longidunial, Corner Cracking), Mean Joint Faulting and mean IRI
