There are many different mixtures of asphalt that are designed specifically to address temperature and load variations. However, they continue to break down and form potholes, ruts and dips due to poor compaction. The most important factor for a long-lasting and durable road is attaining sufficient and uniform compaction of the asphalt material. My 3D Paving Machine intelligently delivers more or less asphalt material across the entire road surface to address existing surface variations. This will maximize compaction and increase the durability and life-expectancy of the road.

We will still have to mill in order to maintain curb-height as well as to remove areas that contain potholes, ruts and top-down cracks. But there will be many areas that we won't have to mill the entire road. Trenching out only the potholes, ruts and cracks and then in a single pass provide a 3D shaped asphalt layer that will compensate for the trenched out areas and at the same time provide a thin overlay of asphalt to the rest of the road addressing surface variations as needed. This new layer of asphalt will be delivered to maximize compaction which will extend the life of the road and prevent us from having to return in the near future to repair it.

Great Question! I do have the U.S. and International patents for my 3D Asphalt Paving. This should protect me against the honest players. As for ISIS, I will have to rely on the fact that the technology utilized in this approach (Lidar, proprietary algorithms, and manufacturing techniques) will not be easily accessible to ISIS in Syria and Iraq.

In order to produce a durable and long lasting road you have to deliver the appropriate amount of gravel (aggregates) to the voids as the aggregates form the mineral skeleton of the road surface and support the heavy loads. We will use the standard sized array of aggregates with this method. As you adjust the mixtures of asphalt material with larger or smaller aggregates the amount the material compacts changes. With this change factored into the design of the shaped asphalt layer my 3D Asphalt Paving Machine will automatically deliver more or less asphalt material accordingly. Once you attain the capability to deliver more or less asphalt material across the entire width of the surface to be paved the possibilities are endless.

I'm afraid I don't have figures to answer him with. The basis for claiming a cost savings is based on idea that this technology can perform asphalt paving in a single pass whereas current asphalt paving machines must make multiple passes when higher lifts (thicker layers) are required or require the entire road surface to be milled down flat to provide a flat surface for 2D asphalt paving machines to be effective. Both of these scenarios cause more and longer lane closures which increases the cost of the project as well as adding to the delays and costs to the public and private sectors as they sit idle in road construction related traffic congestion.

My 3D Paving Machine would likely be of standard width (8FT-20FT) but theoretically can be made as wide as necessary to address any application.
