Life Cycle Event Materials and Transport

The following controls are located on the Input -> Life Cycle Page.

This page shows the eLCAP-generated materials, quantities, and means of transport for all activities for the selected event; it also allows a user to manually add and delete materials.

When an activity is defined and saved, eLCAP will generate a default material to be used (e.g., a specific kind of HMA when adding an HMA layer) and a list of the construction equipment necessary to implement the activity. eLCAP will also compute the quantities of material using the project limits (post mile start/end and number of lanes), the cross section defined on the Project Information page, and the thickness (add layer or remove material) specified for the activity. eLCAP will also provide time estimates for each piece of construction equipment. The default material and the computed material quantities and equipment time estimates may be edited.

You may delete any or all of the items generated for an activity. In addition, you can manually add materials and equipment. In fact, you can skip defining any activities at all and directly add materials and their associated quantities, and equipment and its associated times of operation. But in most cases, defining activities for an event is more efficient than manually building lists of materials and equipment.

Clicking the links in the Source Name column will display a form page with the data for the item. For example, if you click the “HMA with 15% Binder Replacement, no Rejuv” in the Source Name column below a form page will be displayed. Listed on that form page will be all the input flows and their associated quantities needed to produce 1 unit of HMA. If the HMA is an eLCAP library material, no changes can be made to it, but if the HMA is a user-defined/custom HMA mix, changes can be made.

The following discusses each control associated with adding a material for an event. Each row in the grid is a single material, with or without a transport, for the selected event.

1.This control list the types of a material, e.g., HMA, PCC, AB, etc.

2.This control lists the specific materials for a material type. Clicking the name of the specific material will bring up form showing the flows that go into the material mix.

3.This control gives the material density. This value comes from either the Library material or the user defined mix. In both cases, you may change it when adding it to the material grid.

4.Select the units for the density.

5.Supply a value for the amount of the material to use. This value is computed by eLCAP, using the project limits, the cross section and the layer thickness, when the material is generated when adding an activity. It needs to be supplied by the user when manually adding a material.

6.Select the units for the quantity.

7.Select a transport to get the material to the job site. The transport is pre-selected when a material is generated when adding an activity. You need to select a transport when manually adding a material.

8.Supply the two-way distance for the transport.

9.Select the units for the transport distance.

10.Operations to be applied to the activity (row): Add, Delete, Insert, Cancel and Save.

11.This button is used to add a material to the end of the bottom of the list.

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).
