buying the asphalt and transporting it to where you need is expensive.
the equipment for paving is also expensive and the fuel to run the equipment.
an unpaved macamadized road would be ideal for somaliland, all you need is earth, rocks and lots of manpower.
we have tens of thousands chewing qat, a 300 km macadamized road would cost only labor 5000 men working 12 hour shifts could get it done in under a month and you would probably pay just $3 milion or less.
The problem is maintenance, an asphalt paved road will need maintenance every 5 years, while your unpaved macadamized road will need to be mainatined every couple of months.
but since we have massive unemployment, whats wrong with thousands of men earning a clean living through hard labour?
you built it for $3 million, why not maintain it for $500,000 every year?
i think it is justified.
