Have you ever been stuck in traffic around a road construction site and asked yourself, "Why does it take so long?" and felt frustrated because it seems like everyone is just standing around and not doing much of anything? We understand how you feel, but after researching this problem we have come to the conclusion that this is not the fault of the hard working men and women tasked with building our roads and highways.
Rather, it is a result of the out-dated tools and methods used to build and rehabilitate roads and highways around the world. Current asphalt paving machines utilize a flat plate called a screed to measure and deliver asphalt material that is then compressed to make a suitable driving surface. The core design of an asphalt paving machine has changed little since they were invented in the early 1930s.
So even though we drive around in some of the most technologically advanced and environmentally friendly automobiles, we're basically fixing our roads today with the equivalent of a Model "A" Ford.

Current asphalt paving machines, with their flat screeds, are only adequate when used on a flat surface.
They have NO ability to incrementally adjust the amount of asphalt that is delivered across the width of the surface to be paved.
For example, if a flat layer of asphalt is laid down over an existing road surface that has typical road deformities (such as bumps, dips or ruts), they don't deliver enough material over the depressions.
So when the heavy roller comes along the material around the depression compacts first, causing the roller (with its flat compacting surface) to bridge over the depression and the asphalt material doesn't fully compact.

By merging our Revolutionary Design for an Asphalt Paving Machine with Lidar Laser Scanners and Advanced Computer Modelling we can accurately deliver the right amount of asphalt material to any location on the road surface.
With a 3-D shaped asphalt layer we can achieve a uniform level of compaction resulting in a long-lasting smooth driving surface.
And since our method will be able to compensate for any surface variation encountered we can minimize the preparation work, greatly reducing and in some cases eliminate the need to mill down the entire surface flat.

APT is excited to announce that we have received a National Science Foundation STTR Phase I Grant to further the research and development of this exciting technology!.
A Professional Feasibility Study of this technology was performed in 2002 by CTC United Defense, (Acquired by BAE Systems, 2005).
At the time they specialized in Heavy Equipment and were a major supplier of Tracked Combat Vehicles to many governments around the world.
The results stand true to this day.
A 3-D Asphalt Paving Machine as proposed by Advanced Paving Technologies is not only Technically Feasible but can be built mainly from Off-The-Shelf components.

Pre-pledges are a non-binding verbal or written pledge that you will make your actual pledge when the campaign starts.
This assures that we can show positive support on the opening days of the crowdfunding campaign and are very beneficial to the overall success of the campaign.
Once the process is complete, 3D Asphalt Paving Machines will become available to road construction contractors for use on our roads.
This crowdfunding campaign will raise funds to initiate step two of the process.
The research completed at the UC Davis Pavement Research Center will officially verify that our 3D paving method works, which is necessary to take it to the next level of mechanical engineering.

This brief video depicts our vision of the right way to pave an asphalt road.
Using the latest remote sensing technologies and advanced discreet element modeling, coupled with a revolutionary design for an asphalt paving machine we can rehabilitate asphalt paved roads in a fraction of the time and cost.
This will minimize the inconvenience, costs and wasted fuel associated with construction related traffic congestion.
This will reduce the carbon footprint of the Road Construction Industry as well as the General Public who are Tired of wasting fuel while sitting idle in road construction traffic.
