A mechanistic/empirical pavement thickness design program based on familiar Asphalt Institute methods. An integrated pavement design suite for highways, streets, parking lots, airports, and industrial facilities supporting heavy wheel loads.

The software is written in strict conformance to the Asphalt Institute MS-1, MS-11, MS-17, and MS-23 manuals. The Asphalt Institute developed SW-1 to provide users the capability to design asphalt pavements for highways, streets, parking lots, airports, industrial facilities supporting heavy wheel loads, and other applications. SW-1 provides users an integrated pavement design suite to provide an unparalleled range of capability. A few examples of the uses of the SW-1 program are:

• Interstate Highways
• Urban arterials and collectors
• Residential streets
• County roads
• Driveways
• Parking lots
• Marine applications
• Boat ramps
• Port facilities
• Log sorting yards
• Commercial airports
• General aviation airports
• Military airfields
• Advanced analysis using DAMA

Notice: The Asphalt Institute has discontinued the SW-1 Thickness Design & SW-2 Mix Design software packages. There is no plan to update either software package. The Asphalt Institute is allowing SW-1 and SW-2 to be downloaded free of charge. However, No support is offered or available for the SW-1 or SW-2 software package.

SW-1 will require a one-time unlock key be generated. Once the application is installed, the first time it is run, the splash screen will display an 18-digit code. Email that code to info@asphaltinstitute.org to receive an unlock key.
