Large quantities of steel slag are generated annually throughout the world. Some slag from steel manufacturing is reused in the generation of other materials, such as hot mix asphalt aggregate, pipe filling, concrete, among others. The research aims to enrich the mechanical characteristics of soils and minimize road construction costs. The objectiv...
The goal of this investigation was to compare the chemical additives Consolid 444 and Con-Aid to improve the bearing capacity of a clayey soil. The samples were taken from the section of the Pedro Ruiz - San Carlos highway between km 3+000 and 4+000, province of Bongará, Peru; likewise, laboratory tests were carried out to determine the physical an...
Open Access Article / The cowpea aphid (Aphis craccivora Koch) is an economically important pest, whose feeding effects cause stunting, delayed flower initiation and yield reduction in cowpea (Vigna unguiculata L. Walp). Host plant resistance offers an alternative for controlling aphids; while simultaneously reducing reliance on chemical pesticides...

AbstractThe assessment of the water-physical parameters of soils by indirect geophysical indicators is rather simple and enables the characterization of environmental objects of various volumes. This article presents the results of the determination of kinematic parameters of elastic waves in clay soils with different values of the liquidity index....
Road infrastructure construction generates direct impacts on biodiversity such as habitat fragmentation; death of animals by run over; deforestation, noise pollution and particulate matter; deterioration and depletion of natural resources due to the exploitation of sources of materials. Chemical stabilization is presented as a technical, economical...

The performed investigations were focused on analysing the variability of geological-engineering properties in clay soils from central-eastern Europe with regard to microstructures. Thirty-nine soils differing in origin, lithology and microstructure type were selected for analysis. Results of studies on lithological and physical and mechanical para...

Chemical ground improvement of soils of poor quality for construction has been increasingly used as a means of promoting sustainable construction practices. The production of conventional soil stabilisers such as cement or lime involves non-renewable natural resource and energy consumption and high carbon dioxide emissions; therefore, alternative s...
ABSTRACT Brown Nitossolos (Nitisols) and Latossolos (Ferralsols), according to the Brazilian System of Soil Classification (SiBCS), have a “caráter retrátil” as their distinctive property. Because this is a new topic, it is necessary to propose methods for evaluation. The objectives of this study were to evaluate methodologies for quantifying the s...
