STUDIES ON PAVEMENT STRUCTURE COMPONENTS IN WATERLOGGED AREAS

This paper appraises roads in waterlogged areas in two typical Middle East countries, Kuwait and Jordan. In waterlogged areas, the two most important factors, leading to failure of roads under increased traffic, are: (1) the higher moisture content of the subgrade; and (2) inadequate thickness of the crust. Pavement distress is due to: (1) the rise of ground water; and (2) the concentration and crystallisation of soluble salts. The available remedial treatments are: (1) depressing the level of subsoil water; (2) increasing the road crust thickness; (3) constructing an embankment to raise the road level; (4) cutting off the capillary flow; (5) providing vertical sand drains; and (6) using fabrics. Evaluation studies have shown that, to obtain a better knowledge of road performance, the relation between age, climate, land form, and chemical and mineral composition should be established. The paper presents the results of: (1) an investigation of the use of locally available clean sand, to act as a capillary cut-off layer in Kuwait; and (2) a recent study of expansive subgrade soils in Jordan.
