The paper presents a complex method for increasing water resistance and reducing crack formation by using a prefabricated foundation of soil-cement slabs with surface processing with a hydrophobizing material on basis of organosilicon compounds. Theoretical, laboratory and full-scale experimental studies were made. Theoretical studies are based on the substantiation of the geometric parameters of the slab in order to exclude the probability of its destruction under its own weight during building and installation works. The result of the first stage of laboratory studies is the determination of the optimum composition of soil-cement mixture in order to achieve a grade of strength M20. At the second stage, the effectiveness of the influence of hydrophobizing materials "Tiprom U" and "Penetron-Admix" on water absorption and compressive strength of soil-cement was determined. The final stage of the research was a full-scale experiment. In the factory environment, soil-cement slabs were manufactured in metal forms. Based on the results of the research, conclusions about the effectiveness of this complex method were made. The use of soil-cement slabs allows reducing crack formation, as well as to work all year round due to manufacturing and surface treatment of slabs in the factory conditions.

Abstract Asphalt mixture is a building material with many advantages. Therefore, it is most used in road construction. If the asphalt mixture is laid with the prescribed technology, it can withstand load effects to long-term. It is necessary to take samples that will be subjected to laboratory measurements. There are several laboratory test, for example measurement thickness of the asphalt mixture layers, the aggregate fraction, quantity of binder in the mixture, determination of air void in asphalt mixture layers. Samples taken directly from the construction site are subjected to laboratory tests. This article focuses on one of the laboratory tests and it is determination of air void in asphalt mixture layers. The determination of air void in asphalt mixture layers is test in detail, because this effect has influence on the deformation properties of asphalt mixture layers. Therefore, it was necessary to model of air void in asphalt mixture layers with different degrees air void. On this purpose was use program Abaqus. The results were plotted. This graphs showed that increasing the air void in asphalt mixture layers has effect on the expansion of deformations. This can lead to faster pavement degradation.

Wheeled tractors and wheeled earth-moving machines are widely used in road construction, in municipal services. The group of wheeled vehicles, numerous and varied in purpose and design, are general transport vehicles used for the transportation of various types of bulk cargo, and specialized vehicles designed to perform narrow target functions. A characteristic feature of these types of wheeled vehicles is their ability to work not only on roads with asphalt-concrete pavement, but also on deformable soil surfaces. When the wheels roll on the ground, the power consumption required to ensure the movement of the wheeled vehicle increases sharply, questions arise related to the passability of the vehicles, their controllability, and the loads in the transmission. In this regard, it becomes necessary to consider various aspects of the movement of machines in these conditions, in particular, the determination of the power spent on rutting and the depth of the track, which is what this study is devoted to. The use of the “stamp wheel” model in this work made it possible to obtain relatively simple dependencies that make it possible to calculate the track depth and the power spent on rolling both a single wheel on deformable soil, and during the sequential passage of the wheels with an expansion of the track, when the next wheel does not move. in the next ", ie exactly along the track laid by the first wheel, and with some lateral displacement. In this case, part of the wheel moves along the laid track, and the other part expands the track, compacting the previously non-deformable soil. The results of calculations using the derived formulas are in good agreement with the experimental data, which indicates the practical applicability of the obtained dependences.

The aim of this paper is to assess the suitability of a significant number of carbonate rocks from the Aitoloakarnania province (Western Greece) for their use as road construction aggregates, in terms of their content in swelling clay minerals. The study focuses on Cretaceous limestones from the Olonos-Pindos zone. Detailed petrographic analysis and the sand equivalent and methylene blue tests are carried out, in order to estimate the quantity of swelling clay minerals in aggregate particles. Special emphasis is given on correlating the results of the sand equivalent and methylene blue tests, as well as on the relationships between these engineering parameters and the petrographic data. The results are evaluated in accordance with the Greek and International suitability Standards for road construction aggregates. Although the results of the sand equivalent test indicate the suitability of the studied samples, the results of the methylene blue test imply that they are not suitable for use in all applications of road construction. Hence, it is proved that the methylene blue test is of fundamental importance for the determination of the lithotypes which are suitable for use as road aggregates in various applications.
