Soil Behaviour

This study uses a critical state soil mechanics perspective to understand the mechanics behind the liquefaction of metallic ores during transport by ship. These metallic ores are transported at relatively low densities and have variable gradings containing a wide range of particle sizes and fines contents. The effect of the fines content on the location of the critical state line (CSL) and the cyclic liquefaction behaviour of well-graded materials was investigated by performing saturated, standard drained and undrained monotonic and compression-only cyclic triaxial tests. Samples were prepared at four different gradings containing particle sizes from 9.5 mm to 2 μm with fines (<75 μm) contents of 18%, 28%, 40%, and 60%. In the e versus log[Formula: see text] plane, where e is void ratio and [Formula: see text] is mean effective stress, the CSLs shifted upwards approximately parallel to one another as the fines content was increased. Transitional soil behaviour was observed in samples containing 28%, 40%, and 60% fines. A sample’s cyclic resistance to liquefaction depended on a combination of its density and state parameter, which were both related to the fines content. Samples with the same densities were more resistant to cyclic failure if they contained higher fines contents. The state parameter provided a useful prediction for general behavioural trends of all fines contents studied.

Identification And Characterization

Results of laboratory and field construction and pavement performance studies have revealed that some apparently substandard or borderline—by temperature zone standards—tropical gravel materials can be used successfully for the construction of low-cost pavements in subhumid climatic zones.The geotechnical characteristics of suitable paving materials have been defined from results of studies carried out on satisfactory and poor road sections over a period of 5–6 years.Important correlations were found between the bearing strength (CBR) on the one hand and some moisture index properties as well as the products of the fines content and these index properties on the other.It is shown that the product of the fines content and some moisture index properties form a useful basis for identifying suitable materials for pavement construction in the moist subhumid climatic zone of Ghana.The paper is a contribution to the identification and characterization of nontraditional tropical and residual paving materials in relation to the environment. Key words: pavements, California bearing ratio (CBR), index properties, fines content, subhumid climate.
