Investigation 844 –Update of Vehicle Classification for County Road Pavement Design
State Aid ESAL Calculator - 11/15/2010 |
||
The State Aid ESAL calculator consists of a two tab Microsoft Excel spreadsheet. The first tab is for use with the recently updated heavy commercial traffic default values. The second tab is for use with site specific heavy commercial traffic percentages. Any spreadsheet cell that is “yellow” requires the user to input a reasonable value. Please have your Excel security setting set to low or click on enable macros for the program to run. |
||
| Below are updated percentage default values for the heavy commercial traffic (HCT) using County State Aid Highways. The updated vehicle classification data contains 8 default values. These default values are based upon whether the road is rural or urban and the projected AADT range. State Aid encourages counties to perform actual traffic counts whenever possible for the design of their pavements. | ||
