5 Km's in 2 days is pretty impressive!

Amazing time lapse. It looked like it was happening at that speed. Obviously not, being a council job.

If it wasn't done at that speed it wouldn't have been much slower looks like a spray seal road pretty quick process but won't last as long as an asphalt pavement.

They do it like that all the time on outback roads with little traffic, They are contractors ( Sami Sprayers ) not council

Single layer of precoat doesn't = good life expectancy.

It's probably rubberized bitumen which holds together better

Depends on how quick they get it down.  One wnaker that I worked for, had one of his trucks get stuck with a load in it, so he decided to use an excavator to clean it out. The corkhead ripped the body clean off the chassis rail.

those blokes are using spray seal not hot mix

for a country road that gets 12 cars a year it will be perfect....

No mills, no batching plants (apart from the local aggregate quarry), no paving suites/gangs. 1/3 of this country's roads are spray seal and with good reason.

[NewieCamper]

The seal process is quick and easy, building something to put it on that will last is the hard bit. Spray seal is no more than a coat of paint for the road, keeps the rain out of the gravel

As said,Most roads in Oz are done like this,  spray seal is quicker/ easier & cheaper, just respray every couple years to maintain it.

dead right
most of the roads around here are done the same way
most of the patchups are because of problems with the base not the surface
there are roads that haven't seen maintenance for 15 years and are still fine
and then there are hotmix roads that need rework after there first winter because of the base

They don't road repairs round this part anymore, they have just bought 50,000 signs - much cheaper.

Around here they start like that, then a 2nd coat with bigger metal a few weeks later and then a 3rd coat with finer chip.
Seems to last ok with several hundred vehicles a day.
Never see hotmix anywhere on secondary roads.
