we live in a world of unhinged superlatives, its a lost cause trying to be exact, anywhere outside of actual engineering,and I bet you would eat MY socks, to get a look at something that could plausably increase YOUR self healing, definitions and terms be damned,right,:)
30% is a massive and if true, unprecidented increase in life span for a road surfacing material, and would have profound positive impacts on not just civil engineering, but knock on benifts, for ecological and climate issues
- gcanyon 2y agoTotally agreed, 30% would be an awesome improvement if true and cost effective, I'm just grousing about the term "self-healing".
- toss1 2y agoPerhaps consider it 'self-healing' as opposed to 'self-remanufacturing'? Biological wounds often heal with scar tissue which generally prevents the situation from worsening, but is still not as strong as the original undamaged tissue or bone. If it re-manufactured itself, it'd be as good as the original. This seems a bit like that, leaking the vegetable oil into the crack, as blood seeps and clots into a cut, then the bitumen and aggregate can flow together in hot days unhindered by the ordinary-occurring oxidization. Still not as good as undamaged, but better. Seems like an at least good-enough term?
- illusive4080 2y agoYou have to factor in the additional cost of these micro capsules: How hard is it to mix those in on site? What’s the cost to produce them? How fragile are they to work with? Do they hold up in real world conditions? Traditional methods of resealing roads are effective when done at the right time. It takes proactive maintenance. Until this is actually tried in the field in real world conditions I’m not holding my breath for this as a successful method.
