    Hello,
    First of all I would like to appreciate the effort of finding a substitute to the traditional road construction material.

    How can i know more about it?

    Awaiting response..

    It’s good that research engineers are thinking about this but I suggest pushing the boundaries further. Why are we trying to emulate the engineering, mechanics, distribution and transport systems, and personal decision-making that were only made possible as a consequence of fossil fuels and the internal combustion engine? These are the past, so renewable energy alongside reducing, reusing and recycling need to be treated differently. We need to ask, “what can THESE technologies do?” rather than how can they copy the past, and in a way that is regenerative and restorative to nature, rather than consumptive. It will be a massive waste of your cleverness and effort if great minds and ideas are focused solely on copying the past but just with a reduced environmental footprint.

    We need to think completely differently. Small, local supply chains, real circular economies, multiple use systems, lifestyles based on small distances, and mass-transit systems are the future. Think about it: the motor manufacturers are clearly intent on persuading us that we need to continue to rely on private vehicles; they would, wouldn’t they? So by their reckoning, there will still be millions of EVs, which will therefore still come with a massive, collective environmental footprint. Even if lithium is currently plentiful, one day it won’t be; so we will simply have kicked that new environmental impact can down the road for future generations to deal with, just so that we can carry on more or less as we are, with the same vested interests positioned to benefit as before. And let’s not even get started on the ferocious and irresponsible environmental impact of deep ocean mining for mineral nodules!

    So, why are we trying to continue to build roads at all? Whatever form of bitumen we use, it all emits CO2 as it decays; everything decays! The motor manufacturers are also trying to persuade us that driverless cars are the future. Well, what does a row of driverless cars represent? It represents a driverless bus or tram. What does a row of driverless trucks or HGVs represent? A driverless train! So, cut out the waste in the middle, and switch wholesale to mass transit via e-buses, e-trams and e-trains! We can do this. With some adjustments for gradients and bends, we already have the infrastructure to put these on: roads! And the spare lanes would provide room for conduits for electricity and superfast fibre connectivity too, so that we could bury our electricity pylons and create a better, disaggregated electricity distribution network.

    This sort of mass transit can support regional and local roll-on-roll-off goods distribution networks, with EVs used judiciously for the final, local transport and distribution; with new green employment provided at each of the ro-ro nodes.

    Food for thought?
