Quality of labour - intensive compaction of unbound granulate road bases Vol. I and II 1999. Quality of labour - intensive compaction of unbound granulate road bases
Vol. I and II / by K. Jaishi. - Delft : ITC, 1999. - 113 p.,135 p. ; 30 ABSTRACT Labour-intensive
construction of roads is very popular in the developing world. The reasons
behind that are obvious. As most developing countries have a surplus of
labour and a shortage of foreign exchange, labour-based techniques would
also offer an employment-creating alternative, which uses only limited
amounts of foreign exchange. Many studies and researches done in the field
of labour-intensive road construction in 70’s and 80’s by
International Labour Organization (ILO) and World Bank (WB) have confirmed
its technical and economical viability. In
one hand the quality of road constructed by labour-intensive method should
be comparable to that constructed by equipment-intensive method and it
should not result into the poor quality of road. At the same time in other
hand labour-intensive does not mean that construction has to be done
without any tools and equipment. Of course, some simple equipment and
tools at different stages of construction are needed. For instance during
the construction of an earthen embankment or a road pavement some sort of
compaction equipment is needed. The purpose of this research was to
investigate the quality of compaction of unbound granulate road bases in
relation to their compactive and mechanical behaviour by using vibrating
plate as a simple labour-intensive compaction equipment. In this research an extensive literature review is made in order to get an insight into the factors affecting the compactive and mechanical behaviour of the unbound granular material. Furthermore a review has been made on previous studies and researches in the field of labour-intensive road construction and about the uses of unbound granulate road bases.
