Based on the performance of existing designs and using analytical approach,
simple design charts and a catalogue of pavement designs are added in the code.
The pavement designs are given for subgrade CBR values ranging from 2% to 10%
and design traffic ranging from 1 msa to 150 msa for an average annual pavement
temperature of 35 C.
The later thicknesses obtained from the analysis have been slightly modified to
adapt the designs to stage construction.
Using the following simple input parameters, appropriate designs could be
chosen for the given traffic and soil strength:
- Design traffic in terms of cumulative number of standard axles; and
- CBR value of subgrade.
