This spreadsheet estimates the asphalt viscosity. The results are useful for a number of asphalt design and analysis tools including the MEDG Asphalt Design Spreadsheet.
The spreadsheet estimates the asphalt viscosity from the asphalt penetration value. This is very useful for preliminary design or for evaluating existing flexible pavements.
The spreadsheet also includes a unique tool allowing the user to see the effects of different penetration values. 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.
