Road construction on swelling soils: the case of Strymi Soils, Rhodope, Thrace, Northern Greece
Abstract Worldwide, the cost to construction related to swelling clay soils is greater than the damage caused by floods, landslides and earthquakes together. They have been called “a hidden disaster”. In this paper, the origin, mineralogy and physical and engineering properties of some swelling soils from the Strymi area of the Rhodope plain, Thrace, Northern Greece, are examined. These soils were found to have over 50% of expansive lattice minerals (smectite, vermiculite, illite and interlayered swelling minerals). Remoulded samples were found to have high plasticity and CEC with volume changes of 4–30% and swelling pressures 160 to 950 kPa. Undisturbed samples had volume changes of 2–3% and swelling pressures of 40 to 110 kPa. Some specific construction techniques like replacement of the natural soil, use of geogrid and intense drainage systems were used for the foundation and the cut slopes of “the New Egnatia Highway” on these soils.
