Your friend is full of it. Most rubberized asphalt concrete in the western US uses 20% rubber, and that is mostly in the form of rubber granules mixed in. These come directly from recycled tires. So: 1) they are tire rubber - if they were melting then so would the car/truck ties. 2) they are not continuous on the surface, so there would be no continuous layer to slide on. 3) It is impossible for most people to tell if the surface has rubber or not - generally you need a core sample and a microscope. For terminal blends and plastic modifiers, you have to do a chemical analysis of the recovered binder.

Also, rubberized AC has mostly the same noise characteristics as conventional AC. You might be thinking about open-graded asphalt concrete, which is significantly quieter...

The problem is not how they are licensed (public, open source, whatever). What Oracle claim is that their copyright precludes unlicensed copies - so IEEE could require "posix certification" for all libraries implementing the POSIX API, so they could prevent glibc or any other "libc" from being distributed. That might not be a huge risk for POSIX, because of the IEEE involvement, but there are a lot of APIs out there.

As someone with a PhD in Pavement Engineering, and an active researcher into pavement design, let me say this is a classic case of someone thinking that because something looks simple it is. Pavements are the most complex civil engineering structures to design, because they are the only structures designed to fail in fatigue. My wife showed me their video the other day, and all I could do was laugh. Reading their FAQ now, shows they've never asked an actual pavement engineer for their input (and FHWA funding shows nothing, in fact googling shows that they're not even really being funded by the FHWA research budget but by the Small Business Innovation Research (SBIR) program i.e. this is money to promote small business, the research is a secondary goal).

Just a correction for you though - there is not really an AASHTO testing protocol, that was a one off test done 50s and 60s. Now, most proof testing of these types of innovative designs are done by accelerated pavement testing.

Before we even look at the engineering, look at the cost: the highest cost pavement currently are precast concrete slabs, which are similar in some ways to this idea (except they are 50 times the size). They cost about $3 million per lane mile to install. There are over 8 million lane miles of public road in the US, so their idea in their video of covering all the roads in the US would only cost $24 trillion (or nearly twice the US annual GDP) assuming they could get the cost down to that of concrete... Assuming for the moment that the solar panels themselves are cost neutral, just the cost of the glass and support structures would make this impossible to afford.

From an engineering perspective, you have functional and structural criteria. Functional are skid resistance, spray, noise and light reflectivity. The glass would polish, resulting in low skid resistance at high speed, and bad light reflection. Their textured surface would be OK for low speed skid, but really bad for noise and spray, even with drainage between the panels. Many new pavements have a porous top layer for this. Their paving stone like pattern would be really bad for noise (like block paving). Putting LED lights into pressure sensors for animals would be fun, but probably not reliable, and on roads you have to have systems that are reliable because either drivers can trust them, or they are a waste of time.

Structurally, the fact that they refer to gross vehicle mass is a dead giveaway that they don't know the first thing about pavements... The critical number is wheel load. Their panels look to be an awkward size between an interlocking block paver where the wheel load is spread across several blocks, and a concrete slab. The panels would need to be connected in such a way that they can expand and contract, with sufficient load transfer between panels for the entire surface to act as a continuum. With this size of panel there would a lot of flex at the joints, which would break most materials. Concrete slabs get joined using 1 inch dowel bars... Assuming these were placed on existing pavements, maybe they would work, but my guess is that they would get beat up quickly by highway traffic.

Then there is a question of life cycle assessment. Their "numbers" page shows they also know nothing about this either. They just include the benefits... There is no measure of the system, including manufacture, construction, maintenance, etc. They also don't have albedo measurements, etc...

So, to conclude, I don't think this idea is going anywhere fast. Their first step should be to hire a pavement engineer. Then they need to do some lab testing, then use their $1.7 million for an accelerated pavement test to determine if their design can work as a road, before they do any more messing around with electronics... At least their idea is not as silly as the people who want to put piezoelectric generators into pavements to capture all the "wasted" energy...

I've followed trial very closely, and I read every line of the court transcripts of the original trial, although not every exhibit or submittal. They did not make this argument. They also did not make it on appeal, as far as I know. ("The parties have not disputed the district court's analogy: Oracle's collection of API packages is like a library, each package is like a bookshelf in the library, each class is like a book on the shelf, and each method is like a how-to chapter in a book." pg.7) Instead they used poor analogies for what the API is and does, and allowed it to be defined badly.

Having finished reading the ruling... pg 28 is about the doctrine of merger (expression being dictated by idea). That's not what I am talking about. But it does discuss the issue I suggest on pg. 19. I'm talking about 37 C.F.R. Â 202.1(c). The only reference I can find to that statute in this case is in http://www.groklaw.net/pdf3/Or..., where the idea of blank forms is only tangentially mentioned. There was some discussion of Baker v. Selden, but mostly in the context of the SSO of the API. Oracle actually concede in that that the individual method specifications are like a blank form, but not explicitly. Google never picked that up.

Don't be naive. This will be used to shut down APIs. Increasingly the software world is a set of web based and hosted APIs, with big money but little business behind them. Imagine, for example, someone like Snapchat copying Twitter's API to enable their service to grow faster. This ruling, it is stands, will be used by incumbents to shut down start-ups or open-source/non-spyware clones.

Probably Google's biggest mistake at the get go was to not do a /Java/Davlik/g. Since all code needs to be recompiled, this can be done easily by the build system while maintaining a single source file...

This is a very bad decision and is only going to harm the software industry. This is Google's fault for using the wrong arguments. APIs are digital forms. You fill one in and give it to a worker, it does what you asked (possibly with side effects) and returns results. This is not an analogy, it is a fact. Forms are not copyrightable, for good reason. Imagine if every bank had to make up a new name for a 'deposit slip', and someone could copyright "First Name, Last Name" on a form! Google copied Java's API, the same as businesses have been copying each others forms since the dawn of time, and for the same reason: its easier to present a known interface to customers.
