THE ECONOMIC USE OF LABOUR-INTENSIVE METHODS FOR THE CONSTRUCTION OF LOW-COST ROADS

Earthworks, aggregate production and pavement construction are discussed from the point of view of making economic use of labor- intensive methods. In the specific case of earthworks for a road along a hillside, it was noted that: the excavation had to be carried out in a series of benches with separation of the excavating and loading/haulage activites; tools needed to be regularly sharpened and maintained; haulage of excavated material had to use an efficient wheelbarrow; gangs must be balanced to ensure a fair share of work to each worker; a task incentive had to be adopted. Similar consideration is given to earthworks for a road on a low embankment. Various ways of obtaining aggregate are considered and the effect of good planning of a 15 km hillside is quantatively assessed. In the design of a low-cost road using labor-intensive methods, it is pointed out that the earthworks must be kept to a minimum and haulage on up gradients should be avoided. Also, pavement design should be specified in terms of materials which can be efficiently produced using manual methods.
