The Asphalt Institute Mix Design Program (AIMD) is structured for Superpave and Marshall mix design procedures. Many other programs exist that in essence perform the same basic functions as AIMD. However, many of the programs available on the market today are very rigid and cumbersome in structure and do not allow the user to modify the program to their individual needs. The AIMD is an Excel-based program that is password protected to prevent the user from accidentally erasing or modifying the program.
This program was written in strict conformance to the Asphalt Institute SP-2 and MS-2 manuals and test procedures utilized in our research laboratory in Lexington, Kentucky. Many users will find that they use different test methods, sieve sizes or specifications. Therefore, the password to all of the individual worksheets has been given to you to maximize your ability to modify the program to meet your requirements. Caution, however, must be advised. The AIMD contains a tremendous amount of formats, links and equations. Modification of this program should only be done on duplicated templates as shown under the Main User Screen section of this manual. We also advise that modifications be made by knowledgeable designers and those who are proficient in Excel programming.
Superpave Trial Blending Program
The Superpave Trial Blending program is a combination of ten Excel worksheets in one Workbook. This program conforms to Asphalt Institute Manual Series SP-2 and will assist you in performing a Superpave Mix Design analysis for up to five different aggregate gradation combinations at one asphalt content. This program will calculate estimated mix cost and is very helpful when dealing with unknown aggregate sources.
Marshall Trial Blending Program
The Marshall Trial Blending Program is very similar to the Superpave Trial Blending Program. The Superpave Design Aggregate Structure process was modified to fit the Marshall Mix Design process, and will work with other volumetric mix design processes. The Marshall Trial Blending Program also consists of 10 individual, linked worksheets that will enable a designer to prepare up to 5 different trial blends. This process is extremely helpful when the producer is challenged with meeting volumetric properties in the field.
Superpave Mix Design Program
The Superpave Mix Design Program is a combination of seven Excel worksheets in one workbook. This program conforms to Asphalt Institute Manual Series SP-2 and will perform volumetric calculations, plot charts and all other necessary functions needed to conduct a standard Superpave Mix Design.
Marshall Mix Design Program
The Marshall Mix Design Program consists of six linked Excel worksheets in one workbook. This program conforms to Asphalt Institute Manual Series MS-2 and will perform the volumetric calculations, plot charts and all other necessary functions needed to conduct a standard Marshall Mix Design.
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.
