CalFP-Web

The following controls, located on the Tools -> CalFP-Web Page, are used to perform a CalFP design.

CalFP-Web duplicates the behavior and results of the Caltrans desktop version of CalFP which implements the Caltrans R-value design method for new flexible designs. A CalFP design requires a Design Life of 20 years.

Section notes:

1.Shows the currently loaded CalME project

2.Shows the currently loaded CalME trial within the currently loaded project

3.Shows the current structure, as specified on the Project Information page

4.Selecting the "Check" button performs a Caltrans Empirical Design check on the current structure, as shown in section 3. There are two parts to the check: a minimum/maximum layer thickness check and a structural adequacy check. Any informational, warning and error messages will be shown here.

5.Selecting the "Design" button performs a CalFP design. The results of the design are shown in the grid: each row is a design alternative. The thicknesses of each layer in the defined structure are given, as well as additional data items:

•AC GF - this is the AC gravel factor

•RES GE - this is the residual gravel equivalent

•AC Equiv - this the the AC equivalent

•Cost/mi - this is the cost per mile

•Msgs - this column will contain a button with a number indicating the number of messages associate with the design alternative. Clicking the button will display the messages in the pane to the right (section 6).

•Select Button - selecting this button will replace the currently defined structure with the selected design alternative. The currently structure shown in section 3 will be updated with the layer thicknesses for the selected design alternative.

6.Shows the messages associated with a design alternative when the "Msgs" button is selected, if any

7.Selecting this button will display the Reports page so that you can select to generate a CalFP report

A typical workflow scenario when performing a CalFP design might be:

•Define the structure on the Project Information page

•Perform a CalFP design

•Select one of the design alternatives from the design alternative grid (section 5 above)

•Select the "Check" button - you should only see informational and warning messages; there should not be any error messages

•Perform a Mechanistic-Empirical simulation, first Deterministic and then Monte Carlo 

•Generate a CalFP report and download it to your local hard drive

The question mark in the blue circle in the upper-right of the control group allows you to get help on the controls (this topic).
