3D printing asphalt paver: the first road traffic application tool is about to be born

We are often plagued by traffic jams in our lives, moving slowly along road projects and becoming more and more frustrated during the stagnation process. But for John Smith, founder of Advanced Paving Technologies, Inc., traffic jams inspired his innovation: a 3D asphalt paver.

He noticed that after paving the road, the same road deformations and depressions appeared repeatedly, and the inspiration came into being. He explained that the current method of resurfacing roads is almost impossible without the extra cement needed to fill the dents to achieve a long-lasting smooth and uniform road surface. His 3D asphalt paver will compensate for these surface inconsistencies and potentially alter the existing paving and resurfacing methods to make the process “better, faster, cheaper and cleaner”.

On October 15 this year, Advanced Paving Technology Co., Ltd. will launch a $60,000 crowdfunding campaign to produce 3D asphalt concrete pavers. This will mark the first crowdfunding campaign for road technology. The $60,000 will be used to fund the core research of 3D asphalt concrete pavers in collaboration with the UC Davis Pavement Research Center.

In essence, the 3D paving process will be divided into three steps. First, using lidar 3D scanning technology, the 3D paver will scan the surface of the pavement for detailed and accurate 3D measurements. Then, based on these three-dimensional measurements, the computer modeling program will generate a 3D asphalt layer that matches the deformation on the road like a puzzle piece. Finally, the 3D asphalt paver, using a multivariable mortar layer (allowing road engineers to apply more or less bitumen where needed), will be able to create a 3D asphalt felt and apply it to problematic roads, Achieve a high level of compaction.

This new potential paving method has many benefits. As Professor John Harvey of the University of California, Davis Pavement Research Center described the 3D asphalt paver, “providing asphalt in this way, compaction and smoothness levels will maximize roads. Lifetime. One of the results is of course the minimization of road wear, in which part of the road surface is removed for resurfacing. John Smith explained that the longest time spent on this step of resurfacing also led to the most delays in the construction period.

Not only that, but this method of paving also has economic benefits. If you use less money to lay out roads with longer life, you must pay attention to road engineering and road reconstruction, not to mention that many people can save the cost of vehicle maintenance without the damage of potholes. . The 3D asphalt concrete paver also has environmental benefits, which can eliminate extended road works, thereby reducing traffic congestion caused by road works and will help cut carbon emissions.

The "Advanced Paving Technology" program is promising because they have been recognized by the University of Washington, the University of California, Davis Pavement Research Center, the TRANSTEC Group, and Century Construction. They currently have patents in both the US and Europe.

Their Kickstarter crowdfunding campaign will begin on October 15th, and we hope that the "advanced paving technology" 3D asphalt paving project will be implemented as scheduled, and one day in the near future, we will be able to benefit from the 3D printing road. Even reduce congestion!
