[permaculture] Appropriate road surfacing

Picking up on discussion about asphalt.. I live in a small village in 
southern Spain.  We have a smallholding on a track serving about 50 
other farmers.  The track is in really bad repair and the local town 
hall have refused to maintain it.  I want to help organise those of us 
served by the road to club together to pay for a suitable solution.  
The track is approx 1 km long, 5 meters wide and of varying gradient - 
some flatish(~ 40%) and other parts sloping quite steeply.  Much of the 
track is bordered on the lower side by an irrigation channel.  The road 
has, over time, become very heavily pot-holed through heavy rain and 
poor drainage.  With this sketchy information can anyone point me 
towards appropriate ways of making sustainable repairs to the road.  I 
envisage that we could use local contractors who have the kit but may 
not have the knowledge - e.g. someone said "lets concrete the whole 
road" which I assume is not the best way forward?  I'm happy to provide 
any other info that may help to formulate a response.
Thanks in anticipation.
