That's how printed cement drives are done. The stuff they are sprinkling is the cement dye powder which is then trowelled into the surface, then they wait for it to go off and go over with the moulds and bash them into the semi-dry surface to give the paving pattern.
If they do it properly (!) they should come backe the next day and cut expansion gaps and fill with mastic sealant.
No it doesn?t, essentially because with the cheapest dirt roads you are stuck with what there is there because its not affordable to add anything even when the dirt is the worst there is.
With some of the clay soils, all you need is a decent amount of rain even a fully loaded semi sill get bogged right down to the axles and it will be impossible to get it out until it has dried out and that can take weeks or the entire wet season.
And even when you do get it out, that road will be completely unusable by anything until its been graded again.
But it doesn?t work in northern australia and plenty have had to abandon the semi for the entire wet season.
Sure, but plenty of places arent like that and its never going to be possible to add anything to the dirt track to make it useable after a heavy downpour because the track is so long.
Again, that depends on the dirt.
And plenty of dirt tracks are much worse than that.
The guys have spent all afternoon busy washing the pavement and neighbouring drives down and brushing it into the road gully.
As I said, this is a bog-standard 3 bedroom house, and they have spent almost every day (including Sundays) since November last year "working on it". I have no idea what they've been up to out back, but there's rarely been less than 3 at any one time. Even with my pisspoor bricklaying skills, I reckon I could have put a house up on my own in that time.
Needless to say their conduct has reinforced my vow to die before I let another tradesman anywhere near my property ...
It appears that one of the money-saving dodges in current housing estates is to do much of the roads in block paving, but somehow designate it as private access. Seems that can save on street lighting too. :-(
By corrugations I meant transverse corrugations, not 'grooves' along the track. The graded tracks in Oman very rarely if ever got longitudinal ruts in them, just the corrugations.
