When the roads wears where does the plastic go?

Sounds interesting, hope it manages to perform well.

When the roads wears where does the plastic go?

============
just shut up and drink your kool-aid ren
 

but seriously, where does it go?
I would imagine the same place where all the tons of tire dust ends up...a sewer sludge pond and landfill.

Down the storm drain into the ocean.
Probably trying to use plastic cuz the price of oil used for real asphalt is too high

How can they call it asphalt if it's made of plastic?

I can see calling it "plastic road surface" or something, but asphalt is, well, asphalt.

Asphalt, also known as bitumen (UK: /ˈbɪtjʊmɪn/, US: /bɪˈtjuːmən, baɪ-/),[1] is a
sticky, black, highly viscous liquid or semi-solid form of petroleum. It may be
found in natural deposits or may be a refined product, and is classed as a pitch.
Before the 20th century, the term asphaltum was also used.[2] The word is derived
from the Ancient Greek ἄσφαλτος ásphaltos. The largest natural deposit of asphalt
in the world, estimated to contain 10 million tons, is the Pitch Lake located in
La Brea in southwest Trinidad (Antilles island located on the northeastern coast of
Venezuela), within the Siparia Regional Corporation.[3]

The primary use (70%) of asphalt is in road construction,[4] where it is used as
the glue or binder mixed with aggregate particles to create asphalt concrete. Its
other main uses are for bituminous waterproofing products, including production
of roofing felt and for sealing flat roofs.[5]

I guess people have no imagination.  It's like the "dumbed down" version invented for executives to grasp became the official version.

Names should be chosen for the item, not reused based on function.

Me:  Is that concrete? The specs called for asphalt.

Him:  That's Concrete Asphalt.

Me:  So, it's concrete?

Him:  Yes, but we are using it place of asphalt, so we call it Concrete Asphalt.

Me:  Why not just call it what it is -- Concrete?

Him:  Because the plans call for asphalt, silly.

Me:   

While it is covered in tarry gooey goodness it should hold up for a while.  Guessing that once the tar is worn off it will degrade into nothing.  Plastics don't hold up well under UV.  As long as it is not a large percentage of the add in aggregate it shouldn't be too bad. IMHO but im no engineer.
Example, in Waikiki there is a particular hotel that had their outer facade tiled and grouted with epoxy grout.  I may have not fallen out yet but it is definitely not the same color it was.  There man made stones, one goes by the name of quartz.  They do not hold up well outdoors either, serious warping.

If they treat it with chemicals to stop UV absorption, the plastic won't break down from sunlight exposure.

Seems to me, being that roads are in sunlight half the time, they would do that.

Vinyl (plastic) fencing material is treated to resist UV, giving them a lifetime warranty against such damage.

Just saying ....

Tell that to the folks in Guam. . . jus sayin

UV and ocean exposure with humidity is no joke there.  I swear I've seen fiberglass ladders "rust" (degradation resulting in material flaking) away over a few years. . . those are touted as corrosion-proof 

corrosion proof
but not oxidation proof...

So, fiberglass ladders in Guam are indicative of how plastic "asphalt" roads in Hawaii will fare?

How does that work?   

I have a fiberglass ladder.  If you leave them outside in the elements, you're going to get some discoloration and staining.  Doesn't seem to affect performance or durability so far, and I don't see any flaking.  I've owned this for over 8 years and stored it outside next to a shed.

I'm pretty sure you can avoid that by not leaving the ladder exposed to sun, dirt and rain -- like with most tools.  Without knowing how they treat "plastic asphalt", I'm only guessing the engineers would have enough common sense to anticipate the effects of UV on the plastic.

I also have a vinyl fence.  The documentation says if you buy white, it is more resistant to UV because adding pigment to the plastic interferes with that protection.  They also say to not paint the fence, as that also can break down the UV protection.  The fence is as sturdy after 15 years as it was new.  It came with a lifetime warranty for the buyer, and a transferrable 50-year warranty if I sell the property.

So, while I'm not knowledgable on the exact composition of the plastic asphalt, I do know there are solutions to protect plastic from UV rays.

There's some genius who painted a building black across of UFC Gym. When I walk by it at 4pm, I can feel the heat and I'm about 7 feet away from the wall.  Guess they eventually figured it out because now it's white.

When I went to Vegas in 2019, Nathans Hotdogs at the MGM food court had paper straws.  This was my first XP with paper straws.  It sucked.  Fast forward to this year, that same place has plastic straws now. IDK if Vegas also passed a paper straw law.  But I do know they allow plastic bags still.  Which I enjoyed when we did take out and ate at our room. Not only did we have handles to carry the bag, but the plastic containers wasn't all soggy by the time we walked back to our room.

Uh, did you not google corrosion?

It was a joke Sheldon Cooper. . . 

The partially serious part was my personal/work experience on how things in Guam don't last.  Even the "best" stainless steel corrodes super fast.  Freaken amazing actually.

Apparently T-shirt making screens/machines last. If their Mayor who was knee deep in water and still able to make a shirt saying "NASTY", something must have been built to withstand a hurricane.  They should hire the guys who made the machine to make the roads.

Make sure you use a plastic straw!

That's the only place I've ever been that has concrete utility poles, because they got tired of having to replace the hurricane-destroyed wooden poles so often.

Nothing seems to last there.  I went during August, and I don't think I've ever been anywhere as hot as Guam before or since.
