Sub-Base Design for Construction Traffic

This spreadsheet uses two different methods to calculate the maximum allowable traffic loading which can be placed directly on a sub-base. This is useful for checking or designing a sub-base layer which will be required to accommodate significant traffic during construction.

The spreadsheet uses two different methods to calculate the maximum allowable traffic loading on a sub-base. The US method simply uses an empirical formula using the subgrade CBR and the sub-base thickness to estimate the maximum traffic loading. The UK method uses the subgrade CBR and sub-base strength along with details of the design loading to calculate the maximum allowable vertical compressive stress, the minimum thickness and the minimum foundation stiffness. The compressive stress can be calculated using an Elastic Analysis Tool.

The spreadsheet also includes a unique tool allowing the user to see the effects of different subgrade CBRs, sub-base thicknesses or wheel loadings on the allowable traffic loading. The ability to see these results all in one graph without changing the inputs saves a great deal of time, as the user can evaluate the full range of inputs without manually changing them over and over.
