Estimating compaction behavior of fine-grained soils based on compaction energy

Abstract

For successful designs of geotechnical structures, rational determination of the engineering properties of soils is an important process. In this context, compaction parameters, maximum dry unit weight (γdmax), and optimum water content (wopt) are required to be determined at various compaction energies. This paper proposes correlation equations that relate γdmax and wopt obtained from standard Proctor (SP) and modified Proctor (MP) tests to the index properties. To develop accurate relations, the data collected from the literature and the authors’ own database have been used. It has been found that while wopt has the best correlation with plastic limit (wp), γdmax can be estimated more accurately from wopt than it can from wp. In addition, the empirical methods including compaction energy (E) are described for estimating wopt and γdmax of fine-grained soils. The variables of the developed models for wopt and γdmax are wp, E, and wopt. It has been shown that the proposed correlations including the compaction energy will be useful for a preliminary design of a project where there is a financial constraint and limited time.

Use of the Soil Modulus for Compaction Control of Compacted Soils

“…This is likely to be related with the fact that the fines content percentage in the Soil 5 is much larger. This observation is consistent with the common assumption that the optimum moisture is strongly associated with state index properties such as the Atterberg plastic limit (Sivrikaya et al, 2008). The maximum dry unit weight variation with the fines content percentage is plotted in Figure 2.…”

Estimation of soil compaction parameters based on the Atterberg limits

“…As for the parameters of soil density (maximum dry density  dmax and optimum moisture w opt ), six independent variables can be used in order to establish the most accurate according to their determination, as follows: E -energy compaction, G -percentage of gravel fractions, S -percentage of sand fraction, SF -percentage of fine fraction (clay and silt), w l -liquid limit, w p -limits of plasticity and I p -plasticity index. According to Sivrakaya (2013), equation is as follows [17,18].…”

“…The factors that have a major impact on the values of compaction parameters include: soil moisture content (Proctor 1933a(Proctor , 1933b, grain size and soil type (Pisarczyk 2004, Majer 2009, Sulewska 2009, energy expenditure and the method of its transmission (Proctor 1933a, b, Gurtug and Sridharan 2004, Sivrikaya et al 2008, Dąbska and Pisarczyk 2011, Szajna and Lechocka 2016, the power of the impulse (Wiłun 2005), characteristics of the shape and surface of grains (Kolbuszewski 1967).…”
