Cross Section - For Both a Caltrans and a Local Agency Project
The following controls, located on the Input -> Project Information Page, are used to define the roadway cross section.
eLCAP uses the cross section for the following:
•Layer material quantities are computed using the definition of the cross section, the length of the project, the layer thickness and the density of the material

The cross section is defined by:
•The slopes of the embankment, left and right sides
•the unpaved and paved shoulder widths, left and right sides
•The traveled way width
The traveled way is prepopulated using the average number of lanes and the width of a lane (12.0 ft). Selecting the Edit action button puts the row into edit mode and all widths are editable.
The cross section view can be changed to show the activities defined for each life cycle event by selecting the Activities radio button. Once selected, the Life Cycle Event dropdown list and the activity dropdown list become enabled. Selecting an event and an activity will show how the cross section looks for that selection pair.

The graphic above is showing the cross section for event 2 (occurring on 1/1/2020) and activity 3 (adding an HMA layer). eLCAP also shows the computed cross sectional area (14.5 ft2) and the volume (76,560.0 ft3) for the selected event and activity. This volume, along with the material density, is used to compute quantity of material.
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).
