Testing fill material properties see Section

Testing shall be carried out by the Contractor in the laboratory to determine whether or not the materials placed comply with the fill material properties described in the Specifications. [Pg.466]

The tests described in this section can be carried out on disturbed samples. Samples can be taken from a borehole or as a bag sample. [Pg.466]

The sampling frequency can be time related (e.g. two samples per day) or volume related (e.g. one sample every 10.000 m ). It is also possible to take samples on board of a trailer hopper suction dredger. [Pg.466]

Boreholes can be drilled to sample the fill material throughout the entire layer thickness of the fill. Alternatively CPT testing can be used after calibration with the borehole results. The advantage of CPT testing is the speed of execution and the continuous recording of the Cone resistanee, the friction ratio and the pore pressure. [Pg.466]

The minimum and maximum density of the fill can be tested on the material collected in bag samples. Since these values strongly relate to the particle size distribution, the frequency of testing should be adjusted to the observed changes in the particle sizes. [Pg.466]
