Continuing from part 1 and part 2…
Excavation. Another advantage of the pavement profiler is that it can be used as an excavation tool. It is a fast and accurate machine that is capable to load the materials directly into dump trucks in a single operation. Some pavement profiler models are capable to cut up to 300mm in depth and up to 2 meters in width.
Milling. A milling operation is an action of breaking down layers of asphalt that are too deep or too hard. The milling action is performed by road profiler which creates a suitable granular layer that can be left on the surface.
In-Situ Stabilization. Pavement profilers that are capable to perform pavement stabilization are used all over Australia in various road construction projects. These machines strengthen the in-situ pavements by mixing them with suitable binders, so after compaction, the layer that has been recycled has a higher load bearing capacity and is capable to withstand higher traffic stress. The main advantage of using a pavement profiler instead of a mixing machine is that the profiler can pulverize the layers of asphalt to a more suitable sizes and to premix the pavement before the final application of the binder.
Concrete Profiling. The process of concrete removal depends heavily on the compressive strength and the aggregate size of the concrete. If the compressive strength is high and the aggregate size of the concrete is quite big, the process of concrete profiling is very difficult. This can be a very costly and time consuming process where large amount of water is required to minimize the dust and the heat. For such operations, a road profiler with sufficient power/weight ratio can be used for profiling concrete layers to a depth of around 100mm.
Removing Rubberized Athletic Surfaces. When the athletic rubberized surfaces are deteriorated to certain levels, the most efficient machine for removing them is the pavement profiler. The rubberized surface can be removed easily and quickly so that a new layer can be placed.
Recycling. Perhaps the biggest advantage of the road profilers is that they can be used also as recycling machines. The deteriorated layers can be cut out from the surface and later transferred to asphalt making facilities where the layers are mixed with other asphalt materials. This way new and less expensive asphalt layer is created ready for re-usage.
The road profilers provide many benefits for the road construction engineers. An important factor that need to be considered is that the proper selection and proper usage of the road profilers ensures better results in the construction, maintenance and rehabilitation of the roads.
