ABSTRACT

Muskeg covers a significant portion of the land mass in Iran and elsewhere. It creates considerable difficulties for surface transportation. To evaluate the vehicle mobility over
muskeg, it is essential to establish a procedure for identifying and characterizing
those mechanical properties of muskeg that are of importance from a vehicle mobility
viewpoint. The objective of this study was to determine the mechanical properties
of muskeg site at the research farm of College of Abouraihan with a bevameter.
Tests were carried out on muskeg with three levels of volumetric moisture
content (13%, 34% and 86%) using circular sinkage plates which were mounted on
a bevameter. Tests were replicated three times for each of the three levels of
moisture content with circular sinkage plates. Results indicated that the size
of plates and the moisture content significantly influenced the values of critical
pressure (p_cr) and critical sinkage (z_cr).

Key words: Muskeg, Penetration resistance, sinkage, Mat, Peat soil.
