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 4 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.
  
  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
