Reinforcing/paving a Rodden(i.e. in Peat Moss)

[difflock]

(i) No Geogrid used, yet.

(ii) Basically felled the Birch across the Rodden, and attempted to keep all branches laid neatly side by side across the Rodden, and only 3 or 4 deep, with none/virtually none in some places, but deeper in the wetter places.

Have not yet measured the metres done( this and photos a job for tomorrow) but "guesstimated" tipping the 8 wheeler trucks direct, without rehandling, justified the greater depth of hardcore needed to carry them, and the minimal wastage to the sides when tipping, compared to the hire cost of a 2nd digger and 2 or 3 fat tyred site dumpers.

Only placed 40 loads direct, with 10 stockpiled for future use on the wetter rodden.

cheers

OH!

And literally not a 1/2 Hr after the last load tipped, ABSOLUTLY torrential rain.

Lucky or fortunate or wot!

PS

Matelot,

What you mean by geo fibre, Terram or Tensar, i.e. filtration or reinforcement?

What you mean by geo fibre, Terram or Tensar, i.e. filtration or reinforcement?

 

Something like this:

 

Terram Geotextiles | Filtration | Separation | T1000 | Road Construction

 

Without wishing to sound like a civil engineering professor.. Imagine picking up a handful of peat in your hands and squeezing it. The peat will shoot out between your fingers and hands.

 

Look at the open texture of the hardcore. If you place the hardcore directly on the peat the peat will be pushed into the spaces in the hardcore. In time the hardcore/ road will sink.

 

A geotextile between the peat and hardcore means the peat can not be squeezed in the spaces in the hardcore.

Marcus - somewhat after the event but some further reading for you

Thanks for that reference/link Mac, interesting stuff indeed.

I will prob use the Geotextile approach on the as-yet unpaved wetter Rodden, basically working by myself in slow time over the Summer.

Only about 100 to 150 iffy m to do, then I am back onto a dead sand/gravel knowe, so entirely DIY doable.

keep us posted on how things go - we are following behind you with a good couple of Km to fo - in stages so be interested to hear how things work out for you.

Mac,

As I have a habit of doing , "ah wuz thinking . . " the other night,

that what is needed is a contraption to stuff hardcore(or Type whatever stone), into a prefabricated tube of Geofabric,(a kinda like the endless fabric tubes the US uses to store corn in) to constrain the stone, only snag is , said machine be so heavy as to be unsuited to Peaty ground.

Dammn 'n blast!

Anyway, my progress will depend on the erratic/sporadic supply of demolotion hardcore, at £80.00 per 8 wheeler load.

cheers
