Spreadsheet for Comparing McLeod and Kearny Designs
Chip seals are widely used for maintenance of pavements. Two of the popular design methods are those developed by Dr. Norman McLeod and Mr. J. P. Kearny. I am finishing the development of a spread sheet that can be used to compare the two procedures, and that can be taken out in the field during construction so that changes can be made with regard to pavement conditions, traffic during construction, % oil in the binder or other changes that might occur.
The spreadsheet may also be used by agency engineers to establish budgets and for contractors in bidding projects.
At the present time the Kearny method on the spreadsheet does not include the modifications that Jon Epps et al. have made, but those will be added soon.
