Pavement and Surfacing

In RAMM, your roads are composed of several layers. These may include the Subgrade (the native material underneath the road), the Pavement, (the layer or layers of compacted material which make up the base), and the Surface (the material laid on top that the traffic travels on).

With Pavement and Surfacing in RAMM you can add new surfaces easily, see a history of rehabilitation work, and view your road in 3D. Watch An Introduction to Pavement and Surfacing (9:09) to learn more.


Surface, Pavement, and Subgrade

In RAMM the road Surface is the durable surface material laid to sustain vehicle traffic. The Pavement is the layer or layers of compacted material which are the base for the Surface layers. The Subgrade is the native material underneath a constructed road – the foundation of the pavement structure, on which the Pavement layers are laid. Press here for a short video.

Pavement and Surfacing 3D Viewer

Pavement and Surfacing has a 3D viewer. You select a road and the 3D viewer displays the details of a slice of the road. There are also details of the Surfaces Pavements, Carriageway Sections and Treatment Lengths. The Map pointer shows the position of the slice on the map. Press here for a short video.

Add a Simple Surface

You can very quickly add a simple Surface to a Road. You complete at least the mandatory fields. Be careful with the Surface Construction Date. The Surface Construction Date must be a later date than the Construction date of the layer immediately beneath it. Press here for a short video.

Record an Initial Construction

Add Pavement and Surface records here when you haven’t removed, recycled, or stabilised any existing Surfaces or Pavements. Complete the initial Construction details and a Pending Change record is created. You don’t have to add your Pavements and Surfaces all at once, you can add some details and then come back later. Nothing changes until any changes are Approved. Press here for a short video.

Pavement and Surfacing Rehabilitation

Rehabilitation is a key step in the maintenance of Pavement and Surfacing records. Rehabilitations usually involve removing some material from an existing section of road, adding new material and stabilising what’s left and then adding a top surface. RAMM then recreates the road structure based on the layers you’ve added. Press here for a short video.

Add additional material after Stabilisation

What if you stabilise the existing pavement, and then add additional material? Adding material after stabilising creates a new pavement on top of the rehabilitated material. You would complete the Rehabilitation detail, leaving the Added Material Thickness at 0 mm, and Save. Then would then press Add Pavements, and add the new pavement. Press here for a short video.

Add Rehabilitation with no Pavements or Surfaces

You can perform Rehabilitations without adding any Pavements or Surfaces. This is helpful when you are working with an area of road and want to remove the entire area down to a certain level and rebuild different sections of the area in different ways. Press here for a short video.

Seal Widening

You use Seal Widening when you are widening the road on the left hand side, to change the offset of existing Pavements and Surfaces. You enter the additional offset to be added to existing pavements and surfaces within the specified length of road. This means that the offset that you enter on the Rehabilitation view should be based on the 0 mm offset after the road has been widened. Press here for a short video.

View Existing Pavements and Surfaces

Before you commence performing the actual Rehabilitation you’ll want to press View existing pavements and surfaces to help plan the Rehabilitation. Once you have performed the rehab, you’ll want to View the existing pavements and surfaces again to compare the records with what you actually found when you removed the material. Press here for a short video.

Remove, Recycle and Stabilise

To add the Rehabilitation details press Remove, Recycle and Stabilise. The first time you do this you should press View examples to see how this all works. You first check the existing data and amend it if it was wrong. Then you enter the depth of material, if any, that you removed. Next any new material added is recorded. Next is the Depth Stabilised. Lastly the Date is selected. Press here for a short video.

Summary of the changes

Now that the changes have been saved, RAMM has recorded a summary of the modifications. When you check the changes, you’ll see the new layers that have been added. Any layers that have been removed will remain in the history. Press here for a short video.

Add new Surface record

When the Pavement records are complete it is time to add a new Surface record. The Surface Area is first then the Date. This is a single First Coat and it is a Single Coat Seal and these values have defaulted. The binder details are compulsory and these are just demonstration values. Press here for a short video.

View new Pavements and Surfaces

Now it is time to view the new Pavements and Surface records. Open the 3D viewer again. It has defaulted to the Start positions. As the handle is moved along the length of the new records, the 3D viewer moves too. Notice that the outline of the new records are blue. This means that they have not been Approved. Press here for a short video.

Back to top

View Pending Changes

View Pending Changes lists two groups of Pending Change records. Those Ready for Approval have been created by one user for Approval by another. Those which are Pending Changes are records that are probably incomplete and not ready for Approval. Press here for a short video.

View Change History

View Change History is where you can see the changes for a Road whether they were Approved or Rejected. These are only the changes that have been made in the Pavement and Surfacing application. So there is now a very clear Pavement and Surfacing audit trail. Press here for a short video.
