THE USE OF UNIFORM SAND FOR ROAD CONSTRUCTION. UNBOUND AGGREGATES IN ROADS. PROCEEDINGS OF THE 3RD INTERNATIONAL SYMPOSIUM, UNIVERSITY OF NOTTINGHAM, APRIL 11-13, 1989

This paper presents the results of a study carried out to determine the possibility of using local uniform sand for sub-base layers. Two kinds of sand were used: (a) quarry sand, which is an aeolian deposit whose grains are of quartz, and are rounded or semi rounded in shape; and (b) river sand, which is a fluvial sediment whose grains are also of quartz. The physico-mechanical properties and chemical composition of both sands is provided. Pavement structures built over a 10 year period using such sand in their sub bases were monitored and the results are presented in this paper. The following criteria were measured at the time of construction, after 6 years and after 9 years: (a) dry density; (b) moisture content (c) degree of compaction; (d) California Bearing ratio volume per cent; and (e) plate bearing test. Deflection measurements on roads of various sandy sub-base thicknesses (20, 34, and 40 cm) were also obtained after 7, 34, 94, and 261 days, after 6 years and after 9 years. The results show that the pavements are in good condition without any deterioration after 10 years. Pavement structures of this kind can be used for roads carrying light to medium traffic up to 3000000 standard axles. For the covering abstract of the conference see IRRD 827698.
