This method is based on the work of Dr Steve Perkins as outlined in his paper Modification of Austroads Empirical Design Charts for Paved Roads Reinforced with a NAUE Geogrid. A customised version of CAPLab is available with other conversion formula if required. From this improved figure the pavement depth is calculated using the formula from the Austroads Figure 8.4 chart (or Fig 8.5 from Austroads AP-T36/06 for ESA 105) to give the appropriate pavement depth. This method uses a subgrade improvement layer generated from empirical data from the manufacturer Naue GmbH & Co (Naue) based on the proven performance of the SecuGrid and CombiGrid range of geogrids to improve the modulus of the subgrade from the input figure to E = 80 MPA.
The following is an overview of the two design methodologies used by CAPLab for further information and copies of the research papers and source data relating to the design methodologies, please contact Cirtex on 0800 247 839.SIL & Fig 8.4 Method. Further information and guidance is available on the Cirtex website and forms a part of this introduction.
