CBM Special Vehicle Damage

This spreadsheets calculates the equivalent damage done to a Cement Bound Materials (CBM) foundation layer by a special load in accordance with the Australian AustRoads standard. This can be used in conjunction with an elastic analysis program such as our Elastic Analysis Tool to design a CBM layer which can be added into a full pavement design package such as the MEDG Asphalt Design Spreadsheet.

The spreadsheet takes user input values for tensile strain imposed on the top of the Asphalt layer for a standard axle and  for a special load. Then the spreadsheet uses these to calculate the equivalent damage done to the CBR layer by the special load in standard axles. This calculation is done in accordance with the Australian AustRoads standard.

The spreadsheet also includes a unique tool allowing the user to see the effects of different tensile strains without re-entering any of the input data. This makes it easy for the designer to quickly calculate the damage caused by different special loads.
