Application Area Aspect/Functionality Comment
Design traffic Traffic data options Not modelled separately. Pre-defined axle
estimation Pavement load sensitivity loads are adjusted by load safety factors to
Design traffic estimation cater for braking, acceleration and cornering
Design investigation Input data Pavement layer characteristics and traffic
loading
Data analysis options Trial and error
Data import, export and reporting Outcome reported
Pavement analysis Analysis engine Multi-layer linear elastic model
and modelling Analysis options No additional options
Material data and damage models User defined material properties,
environmentally adjusted
Structural capacity estimation Adjust base and subbase layer thickness until
distress criteria are satisfied
Simulation schemes Monte Carlo variability simulation Not included
Recursive damage model Not included

9.6.2 blokPAVE
A software program, blokPAVE, for the design of block paving is being developed as part of SAPDM. This program
will include new models for prediction of block paving performance. The functionality of the software and analysis
options will be the same as cncPAVE, as described in Table 54. The software should be available for distribution in
2014 from Dr Pieter Strauss, pieter@strausscc.co.za.
