Build Roads With Used Tyres 

One thing I noticed is that the gravel wasn't filled in over the tires. If done properly as the original engineer who invented mechanical concrete specified, the quality overall will be higher, and there will be less mini pockets of potholes. Fill in the gravel fill above the tires and get a road compacter to tap down the grade and you may not even need concrete overall

It seems to me, you've misunderstood the idea. behind the Machanical Concrete. The idea of a building material called "concrete" is to be a composite material consisting of a filling agent, bonding agent an some reinforcement. In a traditional concrete - let's call it Chemical Concrete - gravel and/or sand takes the role of a filling agent, portlandcement + water takes a role of a bonding agent ("glues" the particles of gravel and/or sand together), and the rebar / steel mesh takes a role of a reinforcement, which takes tensile stress off the mortar (filler + bonding agent = mortar. After setting it is good in compression, but weak in tension). In Mechanical Concrete you take TDCs (Tyre Derived Cylinders - used car tires with the sidewalls cut off) which can hold high loads in tension (forces, trying to tear apart the cylinder from the conter to outside), tie together forming a geo-mesh, so they do not slide away from each other while filling with the gravel, and fill them with AASHTO #57 Stone (self-compacting aggregate blend of size 5, 6, & 7 stone) gravel. Not with large peaces of stone, but with crushed, fractionated stone! It self-compacts, so no need to use any machinery to compact it. So the TDC acts as a mechanical bonding agent (mechanically, not chemically keeps the gravel together, and the gravel acts as a filler. TDC also acts like the reinforcemet, because the steel inside the tyre threads takes all the tensile stress and does not allow the gravel stones to move. And that's it! No mortar / cement / concrete / rebar mesh needed. The mechanical properties of tyre thred cylinders and crushed stone particles makes the "concrete" out of itself.

Looking forward to seeing the final product

Nicely done steve. But safety equipment wears for employees must be taken into consideration. Successful business also comes with occupational health and safety measures. Thanks

Awesome staff steve

Great work!!!

Great stuff bro, simple and easy to do.

VERY GOOD INITIATIVE.

Just an observation and advise. Noticed the mesh wire is placed on the tires. You must allow for additional thickness to the concrete as the mesh will be sticking out after heavy usage of the road. Mesh will help with additional strength to the concrete and prevent cracks in future And try backfilling with just aggregates (20mm +) and compact. It might be cost saving than concrete.

Yupla ol fit marn. Good job Steve and I will try this out here in Kavieng. Peace.

We only spend US$300 per 100-meter length of road using the Mechanical Concrete (geo-grid containment) system inside our avocado farm.

Amazing u have a good team made it fun to watch , lovely guys , I'm gonna have a go at this tommo thank u and good luck fella xxx

You should probably add structural fiber to the cement mix. The way you did it might be very prone to cracks.

Amazing!

Great innovation and work Steve. Can we have an update on progress and how your mechanical road has held up after 5 months?

nice work but need personal protective equipment

Would it be strong enough if you sliced the tires to half width? It would take less rocks and less work, and not be so tall.

Interesting! Two questions, first, why do you cut both sides off the tire, i.e. can't you leave the bottom-side on? This would form more of a "pot" and less of a ring. I would imagine it helps the gravel stay "level", not disappearing in the softer soil below, no?! Second, if you tie the tires together, would this improve the strength?

Why even use concrete? All you need is smaller gravel on top and then compact it and it's not going anywhere

5:45 guess they've never heard of a rake.

Can I use bitumen in place of concrete in these type of roads

A know a man in PNG named Glenn, an American, perhaps you know him?

Which country are you belongs to

Are your workers bare foot during this cement poor? My friend I hope your crew has something to act as a barrier that I just didn’t see. Rubber boots are common for this. I know a good man that suffers ongoing medical conditions from exposure to lye during a cement poor. His leather work boots were insufficient and then removed them to press on and finish the work.
