A process of soil compaction methods development including new authors’ methodology is described. The importance of soil compaction for engineering purposes is substantiated. Preconditions for Proctor compaction test appearance are highlighted. Proctor’s approach and suggestions for the degree of soil compaction assessing are analyzed. Soviet version of Proctor’s equipment and Modified Proctor compaction test are given. Principal differences between Proctor test, Standard compaction test and Modified Proctor test are presented. The problems and disadvantages of existent soil compaction tests are revealed. New authors’ physical experiment methodology for patterns establishment of water migration in subgrade embankment depth, in the capacity factors of what it is accepted: clay soil type (its number plasticity); moisture, at what the soil was compacted; soil skeleton density; embankment height; «rest» time after subgrade erection and before it’s operation is developed and realized. By laboratory and field tests water migration patterns in compacted subgrade soils depth are established. As a result of statistical processing of research results, the empirical dependence of compacted clay soil stabilized moisture is obtained. Empirical dependence parameter corresponds to maximum molecular moisture capacity at what it is advisable to do the subgrade clay soils multilayer consolidation for their long-term strength ensuring.

The density test for soil in the laboratory can be a mild density test (standard proctor) and a modified density test (modification proctor). Both types of compaction provide different levels of density. This paper aims to analyze the energy produced by both types of compaction. The results show that the compaction modification energy is greater than the standard compaction energy. These results are influenced by the number of layers and the difference of the mass of the pounder on both types of compactionKey words: compaction energy, standard proctor, modified proctor

El grado de compactación de los suelos se evalúa a través de dos parámetros: su peso específico seco máximo (γdmáx) y su humedad óptima (wopt), los cuales se pueden determinar en el laboratorio a través de diversos métodos. Una de las técnicas de mayor uso a nivel mundial es el ensayo Proctor estándar. El procedimiento clásico de este ensayo establece la construcción de una curva de compactación utilizando una sola porción de suelo que se compacta varias veces durante todo el procedimiento. Sin embargo, en la ejecución habitual de esta prueba ha surgido la variante de utilizar varias porciones de suelo en lugar de una sola. El objetivo de esta investigación es aportar información acerca de las diferencias en los resultados obtenidos entre estas dos variantes de la prueba Proctor estándar. Para lograrlo, en un primer grupo de ensayos se determinaron los parámetros óptimos de compactación de dos suelos diferentes del estado de Tabasco siguiendo el procedimiento clásico del ensayo Proctor Estándar. Estos resultados sirvieron de control. A continuación, en un segundo grupo de ensayos y para los mismos suelos, se repitieron las pruebas Proctor estándar pero utilizando varias porciones de suelo en lugar de una sola, esto con la finalidad de que cada porción solo se compactara una vez. Todos los ensayos Proctor se realizaron por triplicado y los resultados se ajustaron mediante una línea polinómica. Comparada con los resultados del ensayo Proctor estándar clásico, la variante que utiliza varias porciones de suelo generó un descenso de alrededor del 1% en los va-lores de los pesos específicos secos máximos, y aumentos en las humedades óptimas en torno al 1.3%. Estas diferencias se originan debido al proceso de preparación de las muestras de suelo en la variante del ensayo Proctor

Abstract The purpose of the work is to analyze compaction parameters of non-cohesive uniformly graded soil – optimum moisture content (wopt) and maximum dry density (ρdmax), obtained from Proctor tests and using vibrating table. The research was conducted on even-graded medium sand (Safgr), of uniformity coefficient CU = 3.10 and coefficient of curvature CC = 0.99. Compaction parameters were examined by using Proctor tests – standard Proctor tests (I and II) and modified Proctor tests (III and IV) in compliance with PN-B-04481:1988, and also standard (A+A and A+B) and modified (B+A and B+B) according to PN-EN 13286-2:2010, and by using a vibrating table in compliance with PN-EN 13286-5:2006 at four sample loading attempts. The moisture content of the samples increased by 1–2% in the range of about 0% to about 10%. On the basis of the analysis of data from soil studies with uniform grain size (poorly compactable soil), it can be concluded that the values of test results ρdmax of medium sand with standard (or modified) Proctor tests according to PN-B-04481:1988 and PN-EN 13286-2:2010 are close to each other. It can be concluded that in the case of ρdmax, the vibrating table method (with the assumed test conditions) allows to achieve results comparable to those of Proctor (mean relative difference 1.88%). Using the vibrating table the wopt values were lower than those obtained by Proctor tests (mean relative difference of 18.84%).

This research is an empirical method for estimating the possibility of using cement dust as an additive for sandy soil during the field compaction process. The soil samples were brought from Al-Najaf city and treated with cement dust .Twenty test models were prepared and compacted in the standard and modified mould of Proctor test. These models were divided into two broad series, firstly consisted of ten soil samples, five from these samples were carried out at constant compactive energy (E=355.5 kJ/m3) for cement dust (4 , 8, 12 and 16%) in addition to one case with no cement dust. This energy is less than standard Proctor test energy. Another retained models were tested with compactive energy equal to the energy of standard Proctor test (E=592.5 kJ/m3) for the same percentage cement dust. The second series of models were involved ten models, five samples compacted at energy corresponding to Modified Proctor Test (E=1197.03 kJ/m3) and other retained models at compactive energy higher than compactive energy of the modified Proctor test (E=2681.4 kJ/m3). The results of laboratory tests which carried out on selected soil showed with increasing compactive energy, the optimum cement dust decreased (this percent was corresponding to the peak dry density in the laboratory) . In other words, the optimum cement dust percents were equal to (4%), (6.6%), (8%) and (12%) for compactive energy (E=355.5, 592.5, 1197.03 and 2681.4 kJ/m3) respectively, and the addition of these percents of cement dust leaded to increase in the maximum dry density (4%, 5.3%, 17.1% and 20.5%) for compactive energy (E=355.5, 592.5, 1197.03 and 2681.4 kJ/m3) respectively.

Full textAbstract:
The use of compressed earth blocks (CEBs) is widespread in the field of earth construction. They present better mechanical performance than adobe and the equipment for their production is simple. Laboratory testing of compressed earth blocks requires large amounts of material. There are variations of unconfined strength testing procedures such as testing halves of the blocks with layers of mortar between them or testing whole blocks in diverse directions. This complicates the interpretation of test results as the shape factor and mortar characteristics influence the results significantly. Static compaction test can be used to produce cylindrical samples representative of CEBs. The water content of soil used for the production of CEBs is often determined in standard Proctor test while experimental data indicate that the optimum moisture content for static and dynamic compaction is different. The present article addresses the behavior of four soil mixes with varying clay content compacted statically with a constant rate of strain. Static compaction curves were compared with those obtained in standard Proctor test. For all the soil mixes the static optimum moisture content was found to correspond to the start of consolidation. The compaction curve presented no wet side of optimum in contrast to Proctor test. The energy needed to achieve a desired density by static compaction was analyzed for soils with varying clay contents. Static compaction was found to be more efficient than dynamic for clayey soils. An increase in water content was observed to help achieving higher densities at low pressures, which can improve the performance of manual CEB presses.

Pelaksanaan konstruksi timbunan jalan (road embankment) merupakan suatu pekerjaan yang memerlukan kajian geoteknik. Kajian geoteknik dilakukan terhadap material timbunan (fill material) yang akan digunakan pada saat tahapan pemadatan (kompaksi) di lapangan. Evaluasi terhadap hasil suatu proses kompaksi mengacu terhadap parameter kompaksi dari fill material yang telah disyaratkan oleh spesifikasi desain. Parameter kompaksi tersebut antara lain adalah kadar air optimum (optimum moisture content, wopt) dan berat isi kering maksimum (maximum dry density, ?dry max).
 Tujuan studi ini adalah untuk menganalisis dan mengevaluasi pengaruh energi pemadatan di laboratorium terhadap parameter kompaksi material crushed limestone yang berasal dari daerah Padalarang, Jawa Barat. Terdapat 4 (empat) variasi energi pemadatan (E) yang ditinjau pada studi ini yaitu : 605 kN.m/m3 (energi standard Proctor, E1); 1.4 E1; 2.2 E1 dan 3.0 E1. Keseluruhan uji kompaksi di laboratorium menggunakan mold dan rammer untuk standard Proctor test (ASTM D 698).
 Hasil studi menunjukkan bahwa peningkatan energi pemadatan untuk kompaksi di laboratorium sebesar 3 kali energi pemadatan standard Proctor, hanya menghasilkan kenaikan gdry max sebesar 5% dan merubah nilai wopt sebesar 3%. Hal ini menunjukkan bahwa peningkatan energi pemadatan di laboratorium tidak terlalu berpengaruh terhadap nilai gdry max maupun wopt , untuk kondisi crushed limestone bergradasi buruk (poorly graded) dengan rentang ukuran butir 0.85mm – 4.75mm.

 Disposal of waste in municipal solid waste landfills is the only way of waste disposal in Serbia, with daily compaction and covering with soil material. Due to less space for the construction of new landfills, it is necessary to use their maximum capacity. Well-compacted municipal solid waste takes up less volume and enables safer storage, so it is useful to previously determine the compaction parameters in the laboratory: maximum dry unit weight (γdmax) and optimal water content (wopt). In the practice so far, the standard method has been used to obtain these parameters (Proctor compaction test) which is common in soil mechanics. However, although this methodology has been adopted, different treatments of municipal solid waste at the landfill (including pre-treatment) indicate the need to change this classical approach. Therefore, during the research, various innovative solutions are introduced, such as the change of the classic flat Proctor hammer, by adding spikes, whose function, in addition to compaction, is partial destruction and shredding of municipal waste. In this way, the operation of compactors (hedgehogs) in the field is simulated. The paper presents the behaviour of four artificially prepared samples of municipal solid waste of different composition. The samples were tested in the standard Proctor apparatus at the same compaction energy, using different hammers, a standard flat hammer, and an innovative hammer with spikes. After that, the geotechnical effects of compaction depending on the applied approach were analyzed.
