Performance-Related Specifications for Pcc Pavements. Volume Iv: Appendix G-Pavespec 2.0 User Guide

System Requirements and Recommendations

PaveSpec is written for IBM-compatible computers running the Windows 95 operating system.  It will not run on earlier versions of Windows (including Windows 3.1) or DOS.  To run PaveSpec, a computer must have the minimum system specifications:

The performance of the software will be greatly enhanced if the system has a 150-MHz Pentium processor or higher and 16 Mb or more of RAM.

Setup of PaveSpec

For the best performance, it is recommended that PaveSpec be installed on (and run from) your computer's hard drive.  Although the easiest way to install PaveSpec is from the CD-ROM, the PaveSpec executable file may also be manually copied to a hard drive or run directly from a floppy disk.  The details of each method are described in the following sections.

Installing PaveSpec From the CD-ROM

  1. Insert the CD-ROM into your CD-ROM drive.  The CD-ROM will start automatically in Windows 95 or NT 4.0.
  1. Select the PaveSpec 2.0 Installation option from the CD-ROM start-up screen.
  1. Follow the on-line instructions to install PaveSpec on your hard drive.   Note: If any problems are encountered with the CD-ROM, consult the readme.txt file contained on the CD-ROM.

Manually Installing PaveSpec to a Hard Drive From a Floppy Disk

If you wish to manually copy PaveSpec to your computer’s hard drive, it is recommended that you create a directory that will house the PaveSpec program file and any database files that you may create.

  1. Start Windows 95 or NT 4.0.  Insert the floppy disk containing PaveSpec.
  1. Use Windows Explorer or My Computer to locate the pavespec.exe file.
  1. Select the pavespec.exe file by clicking on the file name.
  1. From the Edit menu, select Copy.
  1. Click on the existing folder to which you would like to copy the pavespec.exe file.  (You may also create a new folder by selecting New and then Folder from the File menu.)
  1. Select Paste from the Edit menu to copy pavespec.exe to the selected folder.
  1. To run PaveSpec from the hard drive, locate pavespec.exe, then double-click on the file name.  (You may also create a shortcut and place it on your desktop for convenience—see Windows 95 or NT 4.0 Help for information on creating shortcuts.)

Running PaveSpec From a Floppy Disk

  1. Start Windows 95 or NT 4.0 and insert the floppy disk.
  1. Select Run from the Start menu.
  1. Type <drive>:pavespec, where <drive> is the letter designation of the floppy drive.  Then click on the OK button.

What You See When You Start PaveSpec

The primary elements of the PaveSpec main window are identified in figure 1.  When you first open the program, a new default database appears in the PaveSpec main window.

Menu Bar

The menu bar includes four items: File, Edit, Window, and Help.  To display the available PaveSpec commands under a specific menu heading, click on the heading of your choice.  You can then click on any of the commands shown in the drop-down box.

File Menu

The file menu, shown in figure 2, contains 13 commands, each of which is described briefly in this section.

PaveSpec file menu.

New Database—Opens a new PaveSpec database.

Open—Opens a previously saved PaveSpec database.

Close—Closes the active PaveSpec database.

Save—Saves the active PaveSpec database.  If the active database has been named and saved previously, the database will be saved under the previously defined file name.  If the file has not been named and saved previously, the program will prompt the user to enter a file name and storage location.

Save As—Allows the user to save the active database under a new name or in a new location.

Page Setup—Allows the user to specify page formatting for printing (e.g., paper size, page orientation, and margins).

Print—Takes the user to the Print dialogue box in preparation for printing the selected PaveSpec item.

New Specification—Creates a new specification within the active database.

Use Specification—Allows the user to enter actual AQC field data into a previously defined specification and determine corresponding PRS-based lot pay factors and pay adjustments.  More details on using a specification are contained in chapter 4 of this appendix, Using a Specification.

Create Drill-Down Document—Allows the user to investigate the simulation details of of a previously developed specification.  More details on creating and using drill-down documents are contained in chapter 5, Drill-Down Documents.

New Module—Creates a new module.  A secondary menu will appear showing the five different available types of modules: Pavement Design, Design Traffic, Climatic Variables, Maintenance and Rehabilitation Plan, and Unit Costs.

Setup—Allows the user to set up (define or edit) the specification currently selected in the Database Control dialogue box.  Specification definition or editing is accomplished using the Specification Wizard (see chapter 3, The Specification Wizard).

Exit—Exits the PaveSpec program.

Edit Menu

The edit menu contains the following two commands:

Copy Selected Page—Copies a selected output report page to the clipboard.

Preferences—Opens a pop-up dialogue box that allows the user to: (1) specify the preferred units (English or metric) used throughout the program, and (2) set the simulation engine (random-number generator) seeds.  In setting the simulation engine seeds, the user has the following two options:

  • Use same initial seed for all simulations.  This selection makes it so that the simulations are not random from one specification simulation to the next (the initial simulation seed is always set equal to zero).  Each time the user simulates a new specification, the same set of random numbers between 0 and 1 are used to determine AQC sample values.
  • Randomize initial seed for all simulations.  This selection makes it so that the simulations are completely random from one specification simulation to the next. Each time the user simulates a new specification, a different set of random numbers between 0 and 1 are used to determine AQC sample values.  This is the recommended option.

Window and Help Menus

These menus contain commands that are common to most, if not all, Microsoft Windows programs.  See Windows 95 Help for further information.

Toolbar Buttons

The PaveSpec toolbar buttons provide quick access to many common PaveSpec commands. To activate a toolbar button, simply click on it.

icon_database.jpg (2393 bytes) Creates a new database.
icon_open.jpg (1835 bytes) Opens an existing database.
icon_save.jpg (1713 bytes) Saves the current database.
icon_edit.jpg (2144 bytes) Allows the user to change the setup of the document currently highlighted in the Database Control dialogue box.  This function works on all document types (i.e., specifications, modules, and specification-dependent documents).

icon_ucosts.jpg (2317 bytes) Creates a new unit costs module in the current database.

Database Control Dialogue Box

The Database Control dialogue box is used to organize all of the documents in a given database.  The Database Control window is divided into two tabbed sections: Specifications and Modules.  To move from one tab to the other, click on the tab names.

Specifications Tab

All of the developed specifications and specification-dependent documents within the open database are displayed in the Specifications tab, as shown in figure 3.  Within the Specifications tab, each specification-dependent document is attached to its parent specification using a visual outline.  The visual outline may be expanded or compressed by clicking on the boxes that contain plus (+) or minus (–) signs.  The example in figure 3 shows a database containing two different developed specifications, Specification 1 and Specification 2, with two specification-dependent documents attached to Specification 1.

Database Control dialogue box—Specifications tab.

The buttons within the Specifications tab perform the following functions:

btn_open.jpg (1772 bytes) Allows the user to view the output report accompanying the highlighted Specification, Use Specification, or Drill-Down document.
setup.jpg (1952 bytes) Allows the user to edit the highlighted document.
copy.jpg (1830 bytes) Makes a copy of the highlighted document.
new.jpg (1924 bytes) Allows the user to create a new document of the same type as the highlighted document.
delete.jpg (2076 bytes) Deletes the highlighted document.

Note: A outofdate.jpg (1795 bytes) symbol next to a developed specification indicates that the specification needs to be resimulated to reflect one or more changes to variables (or modules) affecting the preconstruction output.  To update the specification, simply resimulate using the specification wizard.

A outofdate.jpg (1795 bytes) symbol will also appear next to any existing specification-dependent document when its parent specification has been resimulated.   This symbol, therefore, indicates that the specification-dependent document is out of date with the current state of the parent specification.  A specification-dependent document may be updated by redefining the document's details in setup mode.

Modules Tab

All of the user-defined module documents within the open database are stored in the Modules tab.  This tab also makes use of a visual outline to organize the five different types of module documents.  An example of the Modules tab is presented in figure 4.  The buttons on this tab basically perform the same functions as the buttons in the Specifications tab.  The only difference is that there is no Open button, as there are no output reports accompanying a Module document.

Status Bar

The PaveSpec status bar provides information describing a highlighted menu item or toolbar button.  To obtain feedback via the status bar, move the pointer over the menu item or toolbar button of interest.  Text describing the item will appear in the status bar.
