Pavement Design (AASHTO 1993) Calculator

Calculator

Results

Required Thickness: 0 inches

Data Source and Methodology

All calculations are based on the AASHTO 1993 guidelines for pavement design. For more information, refer to the AASHTO 1993 Guide.

The Formula Explained

The calculation uses the following formula:

Thickness = (Traffic Load / Soil Modulus)^(1/3)

Glossary of Terms

Example Calculation

For a traffic load of 500,000 ESALs and a soil modulus of 10,000 psi, the required thickness is calculated as follows:

Thickness = (500000 / 10000)^(1/3) = 3.68 inches

Frequently Asked Questions (FAQ)

What is the AASHTO 1993 pavement design?

The AASHTO 1993 pavement design is a set of guidelines developed for the structural design of pavements.

How is Traffic Load (ESALs) calculated?

Traffic Load is estimated based on the number of vehicles and their axle configurations over the pavement's design life.

Why is soil modulus important?

Soil modulus reflects the stiffness of the subgrade, which affects the pavement's ability to distribute loads.
