This equation assumes a 50% reliability where WвЂ™ is the number of standard axles for the traffic lane considered. The AASHTO 1998 concrete pavement design supplement uses the following equation to calculate the number of standard 80kN axles the pavement can carry before failure.

AASHTO Rigid Pavement Design Calculations For this reason it is the AASHTO 1998 supplement which powers the CivilWeb AASHTO Rigid Pavement Design Spreadsheet. As such this was a great improvement on the original 1993 method and it is the 1998 Supplement method which is most applicable to designing concrete roads. The AASHTO 1998 concrete pavement design Supplement included an updated design procedure for concrete pavements which included for the effects of climate and for the effects of joint spacings. The updated 1998 procedure works in a similar manner to the 1993 procedure but includes for the effects of joint spacing.

This time the method was not based upon data obtained from the AASHTO Road Test but on the LTPP database NCHRP project 1-30. The AASHTO 1993 rigid pavement design guide was updated in 1998 with a supplement improving the method for design of concrete pavements. However, the AASHTO 1993 rigid pavement design model is still commonly used in many parts of the world and is very useful as a simple tool for evaluating required concrete road thicknesses at preliminary stage. This has since been superseded by a much more complex mechanistic design procedure known as the Mechanistic-Empirical Design Guide (MEDG). The latest AASHTO method based on the AASHTO Road Test was published in 1993. The American Association of Highway Transport Officials (AASHTO) has published a number of design methods for both flexible and rigid pavements based on a large experimental study of pavement performance called the AASHTO Road Test. Alternatively the AASHTO design spreadsheet is included in the CivilWeb Rigid Pavement Design Spreadsheet Suite which includes 11 different pavement design methods along with a number of other useful design tools including concrete flexural strength calculators. The CivilWeb AASHTO Rigid Pavement Design Spreadsheet can be purchased further down this page for just ВЈ10. It also comes preloaded with climate data for major urban centres in every US state, while a separate module allows the designer to specify climate data making the AASHTO method suitable for any location worldwide. The CivilWeb AASHTO Rigid Pavement Design Spreadsheet includes design modules for AASHTO 1986, 1998 supplement and a faulting check in accordance with AASHTO 1998. It allows compliant concrete pavement designs to be completed in minutes with our unique design analysis tools showing the designer at a glance the optimum concrete pavement thickness.
