“…There are several studies attempting to describe rock weathering according to the type of rock and purpose of the associated engineering problem (Arel and Önalp, 2004), such as Moye (1955), Ruxton and Berry (1957), Dearman (1976), Irfan and Dearman (1978) and IAEG (1981). These engineering geology classification systems have generally been qualitative rather than quantitative, and mostly related to granitic rocks (Arel and Önalp, 2004).…”

“…Mercury intrusion porosimetry technic (MIP) has been employed by many researchers in order to investigate soil structural features as [27][28][29][30][31] and others. Distribution, size and connectivity of pores may be used to define mechanical and hydraulic properties of soils [32,33].…”

“…The specimens were air-dried and after that ovendried at 40º C. Some authors [28][29][30]15] report that in clays oven drying is not appropriated because causes shrinkage and pore diminution, mainly when samples are prepared as slurry. In this case, according to such authors, sample freezing and subsequent sublimation for water extraction is a more appropriate drying procedure.…”

Abstract. This paper discusses the influence of structure in the soil-water characteristic curves (SWCC) of two residual soils of granite formed in a subtropical environment. One soil has a saprolitic nature (named GrSp) and the other shows lateritic behavior (named GrLt). Both materials occur on a slope which presents a extensive history of landslides in the municipality of São José, Southern Brazil. SWCC of undisturbed and remolded specimens were determined using the filter-paper technique. Undisturbed specimens were collected and remolded specimens were produced by static compression of disintegrated soil to the same void ratio and moisture content of undisturbed specimens. SWCC of saprolitic soil showed curves which were modelled as unimodal but the lateritic soil required the use of bimodal curves because of the structure developed in micro and macro levels. Suction levels measured in GrLt soil were higher than in saprolitic soil. Remolding process changed the levels of suction achieved, which is due to the structure and more specifically to the size of pores in the remolded soils. Hysteresis were verified in both materials, but were far more pronounced in the lateritic soil. Analysis of mercury intrusion porosimetry were carried out in GrSp soil. They showed that remolding generates a different pore distribution from the existing in the undisturbed soil.

“…Several attempts have been conducted to give a complete description of rock weathering based on the type of rocks and the associated engineering problems (Moye, 1955;Ruxton and Berry, 1957;Dearman, 1976;Matula, 1981;Murphy, 1985). Generally, the classification systems of engineering geology have been qualitative descriptions of weathered rock masses, which are typically related to granitic rocks (Arel and Önalp, 2004). Komoo (1987) proposed that the dominant mass weathering profiles for granitic rock in Peninsular Malaysia are types A and B.…”
