I’d come. :slight_smile:

I’ve always pored concrete for my streets. Then I tried Hardi board. Lasted two years so it looks like it’s back to pouring concrete. Later RJD

Wow ...you got 2yrs out of it?? I think it was 1 full season in PA....done

Has anyone tried bitumen road patch, to make scale asphalt roads? I need to construct a country road on the DÜRR.

We call that blacktop patch over here. It would need to be laid down fairly thick, at least 1" and has to be tamped pretty good to get it to bind together. The size of the aggregate in it would look way too big for scale roads. That might be corrected by using a sealer after it has cured some.

Speaking of sealer, I experimented mixing driveway sealer with stone dust for patching small holes in my driveway. It worked OK and has lasted for many years. That might be a better option as it could be poured.

Hey Shawn, how about another meet next summer ?

#48

Re the blacktop patch, I wonder if one could press sand into it, as it was curing, and have it stay put?

It’s mostly lump macadam with a tar coating Cliff, and as with the macadam on the real roads tends to form cracks as it ages.The bag needs to sit in the sun for a few hours to become spreadable so you can work it and does not last in thin coated areas. Jons’ idea of sand mixed in black top coating or even roofing cement would maintain a smoother coating and resist much of the cracking normal in paved roads. the coatings and cements are more elastic and UV resistant JMHO YMMV

Thanks Hollywood.

It sounds somewhat flexible.

So for G-ish roads, can it be laid, with a topping of sand or something like that, and be expected to remain flexible?

#51

I was referring to Stone Sand, or Crusher Fines, or 1/4Minus - Whatever y’all call it in your neck of the woods, not fine sand. Ya know - Ballast!

You know I thought Hollywood was talking about macadamia nut shells, and sent me down a rabbit hole. So I had to ask…

Are Macadamia nut shells used in the production of Macadam?

  • The word "macadamia"comes from the name of a Scottish-Australian chemist, medical teacher, and politician, John Macadam.
  • In 1857, German-born Australian botanist Ferdinand von Mueller named the genus of macadamia trees after MacAdam.

What the heck is Macadam?

  • Macadam is a type of road construction pioneered by Scottish engineer John McAdam around 1820, in which crushed stone is placed in shallow, convex layers and compacted thoroughly. A binding layer of stone dust (crushed stone from the original material) may form; it may also, after rolling, be covered with a cement or bituminous binder to keep dust and stones together.

Is Tarmac the same as Macadam?

  • Macadam is also referred to as Tarmacadam** , which is where the name Tarmac (actually a brand name) came from.
  • It is also referred to as Bituminous Macadam and Bitmac. Macadam was invented by John MacAdam in the 1800s who bound smaller aggregates together using naturally occurring tar, hence the term Tarmacadam.

Tarmac, Asphalt, & Macadam Explained.

So there we go John MacAdam (Macademia Nuts); John McAdam (Macadam)- go figure!

the loose end…

Many things have also been named after Sir Ferdinand Jacob Heinrich von Mueller. He even had a Victorian Railways S Class diesel-electric locomotive, S311, named after him. Somewhere along the way the “von” disappeared from the family name and he is remembered in Australia as Mueller here.

That only leaves one @Eric_Mueller question, any distant family history of emigration to Oz?

a bit heavier grit then I pictured Jon.
When you said sand I thought of scale size and dried bagged sand came immediately to mind. For a road type use I picture roof cement with a recipe kind of like making bread. 1 part cement to maybe 3 parts sand. You might need to add more parts sand to keep a grit style appearance. Enough to keep it a pour able mix yet be mostly a grit. This then poured at maybe a 2" thick layer to stand up to the weather.
Guess you could also use the aggregate they mix in paint
What is anti-skid additive?

anti-skid additive is aluminum oxide grit that suspends in the coating, providing a safe, slip resistant surface. Easy to use. Prior to application of floor coating, pour into floor coating and mix. Extremely durable works with any floor coating.

for a non slip tread surface but I think sand would be cheaper.

for a scale asphalt i would mix the liquid tar with sand for pool filters.

No relation…“Von” would imply he was nobility. We come from a long line of peasants! Mueller is the German equivalent of the Korean name Kim, too, making it rather useless as a means to determine relations!

Wow…just re-read the whole thread and it made me want to respond to a post or two but I’ll get nothing but crickets. Kinda choked me up a bit.

This is all Bill’s fault!

I agree David, too many of them have gone on or just drifted away.
