    There is a concrete that heals itself. It is mixed with a bacteria that creates calcium when the concrete cracks and fills it in.

      Is Sporecrete self healing concrete a real thing?

    This is essentially what I thought of for using if cracks form in an O Neil Cylinder, in the Graphene Carbon Fiber/Nanotube Basket, with Graphene carbon fiber/nanotube burs with graphene resin. Just graphene could be poured in with resin and heated up to heat fix everything together.

    I'm not sure this video has the right title, it's appears to only be self-healing asphalt, not concrete, I've never heard of concrete with bitumen in it, and this technology is directly correlated with bitumen (and mixing in steel threads)

      Timmah Asphalt is called Asphalt/Bituminous Concrete, Concrete with cement as the binder is called Cement Concrete (Portland Cement Concrete, if the cement used is Portland Cement)

    The water laying on the road surface which then being struck by a tire at speed causes cavitation is the main factor for road destruction, so the porous surface is the best structure, but wouldnt the sun every summer at peek heat do pretty much the same thing.

    Will this product work in the US? If so, our construction company would love to test it on some road here in SC.

    Can they make those materials conductive with pressure because self healing material is batteries

    Not really 'self healing' if you need to use a machine to do it, but I guess it's still better than having to keep laying new road

    If you look closely, the crack was still there. What exactly does this do?

      Usually asphalt, or however you want to call this type of "street surface", doesn´t appear as a single square beam.
      The crack just visualized a split in the "street surface". These cracks or splits are deadly for the street itself in combination with water and Temperatures. So if you can close those gaps or cracks ..whatever...you prevent the incoming from water and then its expanding in relation to Temperatures.
      That´s how I understod this whole thing.
      If I´m wrong please let me know !

    now what are you going to do about the HIGH LEVELS of TOXICITY of the substance? IN California, it was one of the first group of Prop 65 Substances--industrial substances in such common use they needed to have serious restrictions put on them. Asphalt exposure changed my life! Toxic Encephalopathy, BLIND & on supplemental oxygen for more than 5 years. I beat what MD's said I'd never beat & got back my sight--I still have neurological issues that demand a constant lifestyle of self-healing.

    Ever been at a red light next to an asphalt truck & feel sick? That's cos it's TOXIC. Industrial installations of asphalt (like on a street) in Cali require at least 24 hours notice before installation within 75 feet of a residence--to allow residents a chance to go away during the most dangerous time--when it is mixed, prepped, hot & the fumes are at their most toxic. Read asphalt’s MSDS. & my story’s in my TED bio.

    I would assume not so good for climates with freeze thaw cycles. That stuff would crumble like stale bread in a New England winter.

    How do you get asphalt in your system, did you pulverize it and then inhaled it or something, the fuck.
