SUPERPAVEMixture Design Software

1. Introduction:ePAVE is a computer program based on Microsoft

Excel. The main objective of ePAVE

is to help Engineers and Technicians in the Highway industry to use SUPERPAVE methodfor the design and analysis of Hot Mix Asphalt (HMA). It is designed and based on thepopular MicrosoftExcel to utilize Excel enormous capabilities and the existing experienceof users.

ePAVE contains all of the steps and requirements for the mix design as outlined in theAsphalt Institute Superpave Series No. 2 (SP-2) titled Superpave Mix Design, thirdedition, 2001 printing, the latest release during the preparation of ePAVE (2004).

2. Overview of SUPERPAVE Mix Design MethodThe HMA mix design using SUPERPAVE method is different than the conventional mixdesign methods namely Marshall and Hveem. Three main distinguishing conceptualdifferences are the following:

The performance based binder specifications

The selection of the design aggregate structure

The use of the gyratory compactor.To design any HMA , the designer must go through four steps as shown below.

Step 4:

Moisture sensitivi ty

Step 1:

Selection of materials

(agg., binder, modifiers, etc.)

Step 2:

Selection of DAS

Step 3:

Selection of DAC

The first stepis to select the materials:

The Aggregate

The binder

The modifierThe selection process depends on many variables; the reader is referred to SUPERPAVEworkshop book issued by AdEC and the Asphalt Institute SP-2 for more details.

The second step is to select the design aggregate structure (DAS). Three aggregategradations are developed based on the hot bins gradation to meet SUPEPAVE controlpoints and restricted zone criteria. The Design is based on a given nominal maximumsize. The gyratory compactor is used to compact two specimens for each blend (total 6 x150 mm specimens) at a computed trial asphalt binder. Then the bulk and maximumspecific gravities are measured for each specimen. The height of the specimen at the endof the Nini and Ndes is measured. The data is inputted into ePAVE to compute the

properties of the mix for each blend and used to compare with SUPERPAVE criteria toselect the most confirming blend.

The third step is to select the design asphalt content (DAC). The selected blend from step2 is used varying the binder content at four levels (-0.5, +0, +0.5, +1.0) to compact twospecimens at each level (total 8 x 150 mm specimens). Similar data in the DAS ismeasured and inputted into ePAVE to select the design asphalt content. Finally, to verifythe performance of the mix at the highest anticipated traffic level, two specimens arecompacted using the gyratory compactor to Nmax.

The fourth stepis to check the moisture resistance against water using AASHTO T283.

3. Instructions:ePAVE CD has four file, these are:

ePAVE program (Excel format ePAVE.xls)

ePAVE Example (Excel Format ePAVE Example.xls)

SUPEPRPAVE workshop book (Acrobat reader format handout of theSUPERPAVE workshop.pdf)

ePAVE manual (Acrobat reader format ePAVE Manual.pdf))

3.1 ePAVE Setup:

The setup process is simple, do the following:

Create a folder and name it (SUPEPRPVE)

Copy the content of the ePAVE CD to this folder

Now you are ready to use and view the files by clicking a file to start it.

3.2 Using ePAVE

To use ePAVE Note the following:

Star Excel. For best results select the full screen view from the view menu.

Start ePAVE by clicking on the ePAVE program file

Input the password (adec12345)

The following screen will appear


5/14




Click on the read only to start ePAVE. This is important to protect the main ePAVE filefrom overwriting and allow the user to select an appropriate file name such as the projectname and layer type for example, to save the workbook after data input and analysis.

The opening menu will appear as shown below


6/14




Important Note: The user must make sure that the sheet tabs and row &column headers are disabled; if not go to tools>>> options >> view >>>unselect row & column hears and the sheet tabs (see below). This is

very important because ePAVE is design as a menu driven program thatwill organize and systemize the design process

Click here to start ePAVE, the main menu will appear as shown below.


7/14




To go back to the opening menu click about ePAVE

To start inputting data click on project information

To generate copies of the SUPERPAVE forms click design forms.

3.3 Inputting dataStart by the project information; fill up the data in the green cells as needed. Note thesmall red triangle on the right top corner of any cell, pointing by the mouse to that locationwill open a comment box that contains an important information or hint. After inputting allthe project and design parameters, click main menu to go back.

Click on the SUPERPAVE criteria to go to the input screen of the mixture requirements,again fill the green cells with appropriate data as needed. For a quick reference of thegeneral SUPERPAVE requirements, ePAVE provides that if the user clicks on the labeledbox.


8/14




Select the binder data to go to the input screen shown below; input all data in the greencells as needed.

Now, the basic information of the design has been inputted, the designer starts the design

process by selecting the aggregate data and mix design from the main menu. Thefollowing screen will appear, input the aggregate physical properties and gradation asneeded.


9/14




Then select the appropriate nominal maximum size for which you are designing from thescreen below noting that the reminder of the design process (except the moisturesensitivity) depends on NMS, do not click on the other NMS which are not applicable to

your case as this could yield a wrong design. Always notice the yellow box on the topshowing the NMS and it is the one you are designing for.

Input the suggested blending percentage from each hot bin and for each blend. Alter thevalues of percentages as needed to produce a gradation that is within the control pointsand outside the restricted zone and is in the fine, middle and coarse side.


10/14




Note the decisions and results of the values compared to SUPERPAVE criteria that areautomatically obtained by ePAVE. Verify the NMS. And note the computed values of thecombined aggregate properties as derived from the blending percentage by ePAVE.

Click on the bottom box to proceed to the computation and input of the densification datafor the trial blends. No input in this screen, it is all computed values


11/14




Click on the densification data input, to go to the input screen. Note that it is not needed toinput that complete densification data, unless the user wants to. It is enough to input thesummary table on the bottom of the screen.

After inputting all the DAS densification data, go back to the DAS analysis and resultsscreen; study the results and select the appropriate blend to carry it to the next step, theDAC. Click on the bottom box to go to DAC step.


12/14




Input the required values for the selected blend in the green cells. Complete the input ofthe densification data for the DAC, but, note again, that it is not needed to input thecomplete densification data, unless the user wants to. It is enough to input the summarytable on the bottom of the screen. Click on the box on the bottom of the screen to

View/Print the computation of the volumetric properties and the evaluation of the designasphalt content and select the asphalt content meeting SUPERPAVE criteria.


13/14




View and print the design curves, then select the asphalt binder content that provides4.0% air void, read the corresponding values for VMA and VFA and obtain the Nmaxverification values as outlined in the design method and Input all values in the appropriate

cells. ePAVE will tell you whether the design meets SUPEPRAVE criteria or not.

Click the bottom box to go to the moisture sensitivity evaluation step.


14/14




Input the data in the green cells as needed and this concludes the design process.

3.4 Printing Report

After completing the input of each screen, the user can print the page. After collecting allprintouts (13 pages) , the design report is ready to be submitted to the MOT and theconsultant, with a letter summarizing the report.
