The new SW-1 program is:

• 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.
• Designed to run on common Microsoft Windows ® operating systems including Windows XP. The new Windows-based user interface dramatically integrates previous AI thickness design programs into a single, easy to use program. It features improved data file handling and storage capability. An extensive context-sensitive HELP file addresses common pavement design questions.
• A companion User’s Guide (PDF 3 MB) with example problems is included. The software is written in strict conformance to the Asphalt Institute MS-1, MS-11, MS-17, and MS-23 manuals.
