Beneficial uses of dredged materials for road construction purposes

In Denmark effort is being made to utilize those materials which become available when harbour entrances and channels are dredged. The amount which needs to be dredged each year amounts to 2 mill.m**3. Based on laboratory analyses of collected samples from a number of different localities in Denmark, the applicability of these materials for road construction purposes has been investigated. The laboratory analyses which have been carried out have included determination of particle grain size after washing out particles smaller than 0.075 mm and determination of the sand equivalent value (SE) and loss of ignition as well as calculation of the coefficient of uniformity d(sub)60/d(sub)10 = C(sub)u. The major part of the samples examined consist of sand, fine and medium, with a C which varies between 1.5 and 2.5. The materials could be used as fill in road embankments or for reinstatement after excavation of pipe trenches, such as for filling around pipes. Furthermore, the material could probably be used as subbase/capping materials and fly ash and cement bound sand as a basecourse. In the report, a set of Danish demands have been formulated for road construction materials and a procedure has been described which can be used in future for evaluation of various types of dredged materials for road construction purposes.
