I would like a quick opinion, based on the limited information I am giving here, on the best (i.e price and performance) type of geotextile to use on my project.
We have a site which is reclaimed land, silt/clay at depth and sand for the upper 5m. The site needs access roads and car parks with general industrial type loadings - say trucks with 40 tonne loads / 10 tonne per axle loads.
The roads/car parks will be constructed from graded crushed limestone max size 50mm. The proposal is to grade the sand to level and compact, lay a geotextile, fill with 375mm of crushed limestone in 2 layers, then lay 100mm of asphalt.
My question is whether to use a non woven geogrid ("Netlon type") geotextile or to use a woven ("Terram fabric") type. The important factors are perfromance and cost which includes the cost of the geotextile and the expected saving on thickness of subbase.
Any suggestions?
