Abstract

Many borings in Mansourah City should that there is a layer of peat with thickness ranges from 1.0 to 4.0 m at depths range from 6.0 to 12.0 m all parts of the city and its surroundings.
Peat has a great capacity for taking up and holding water , high shrinkage , great range of density and specific grauity, high void ratio , high degree of permeability , low strength and high degree of settlement in the few hours of loading.
A complete testing programme was performed on samples taken out of the Mansourah City. Results showed that Mansourah peat is a quite complicated and strange material which mean that a great precautions must be done to each a safe highway or building project.
Many figures and relationships are obtained in the paper to help engineers in the design and execution stages but tests must be performed in each individual case.
