Since 1973 Scott Wilson Kirkpatrick & Partners have been designing roads for the Ministry of Communications, Libya. At present a total length of some 2300km of road has been, or is being, designed (see Fig. 1) and of this, more than 900km is out to contract. The roads generally have a 110km.p.h. design speed with a pavement width of 7.5m.
For a design programme of this magnitude, the geotechnical aspects have covered a wide range of problems typically associated with arid environments. This article describes some of them.
