Paving the road of the future. Part 1 of 2

Precast / Prestressed Concrete Pavement. Field demonstrations of FHWAs system for Precast Prestressed
Concrete Pavement used by a number of State DOTs.
The video examines the feasibility of using precast pretensioned panels for roadway segments that are assembled on-site and post-tensioned.

The essential concepts for FHWAs precast prestressed concrete pavement system can summarized as follows:
•Precasting is performed utilizing the facilities already familiar to bridge engineers.
•Stockpiling of precast panels provides for rapid delivery as needed.
•Constructability and performance are facilitated by the design features of the precast panels.

I'd rather see Solar Roadways take over construction of our roads.

Here is a video to solar roadways

[littlewazz]

there is too much expansion and contraction here in PA to use a system like this it will buckle and pop and become very wavy between each section

@rprice33 In that case neither is any other new form of roadway pavement...especially one that won't pay for itself.

@rprice33 so its not available to the US?

Solar roadways aren't possible in a bankrupt country.

@weenorwegian Yes , but they are older. Actually , In Bombay , India , all roads are concrete and they have ingenious methods to actually increase mileage , reduce potholes , and give a smoother ride :D

Precast concrete slabs was used on all major roads all over Easter Europe during the communist era. They are still there and they are awful to drive with their joints between the slabs. Harder than normal tarmac (thus longer lasting) make them tough on the suspension and uncomfortable unless you drive a truck which is able to absorb it.

That is very cool
