Published: June 2020

Steel is a type of material that is widely used as a main material in the manufacture of various kinds of industrial and automatic machinery spare parts. Some mechanical properties of steel that are often used in design are hardness, ductility and toughness. Often in a design, we have difficulty getting steel with mechanical properties that are appropriate with the design. For this reason, engineering carried out mechanical properties engineering, to obtain steel in accordance with design calculations. AISI 4140 steel is a medium alloy steel. This steel is often used for industrial and automotive machinery parts. This research engineered the mechanical properties of the steel, namely the hardness and ductility of the material. The process is carried out by conducting steel hardening at 850 °C followed by rapid cooling with water media. After that, tempering at temperatures of 300 ᵒC, 400ᵒC and 500ᵒC by cooling together with the furnace. The result is hardness and tensile strength of the material has increased, when compared with untreated material. This method is effectively used to obtain mechanical strength values in accordance with technical planning calculations. . Keywords: Tempering, AISI 4140, Mechanical Properties Engineering

Studies and analysis on interlayer bonding in asphalt pavements
Authors: Jaskuła Piotr 
Published: June 2020

The paper describes research works of interlayer bonding of asphalt layers conducted at Gdansk University of Technology. The studies included laboratory and field tests, and calculation of pavement structures with different interlayer bonding models. Laboratory tests included interlayer bonding tests using the direct shear method which evaluated the influence of selected factors on interlayer bonding: the type and the amount of the emulsion, the method and the effectiveness of compaction, vulnerability to dirt, water and repeated shear loads. Field works were focused on the impact of interlayer bonding of asphalt layers on the deflection of pavement structure and the back-calculated stiffness modulus of asphalt mixtures. The analyses of the field tests also included the impact of the asphalt layers compaction ratio on interlayer bonding. Computational analyses of asphalt pavement structures consisted of the simulation of different interlayer bonding in a multi-layered elastic half-space. Calculations were also made by using the finite element method within cohesion and friction models to simulate interlayer bonding.

Published: June 2020

In the paper the results of experiments on concrete pavement with exposed aggregate technology placed in two technological layers were presented. The following properties were measured: compressive strength, flexural strength by two methods: two-point loading and centre-point loading, tensile splitting strength of cubic and cylindrical samples. The study was performed for two type of concrete with a maximum aggregate size Dmax 8 mm (concrete applied to the upper layer of concrete pavement - GWB) and Dmax 22 mm (concrete used for the bottom layer - DWB). After the analysis of the tests, the correlations between compressive strength and tensile strength, measured by flexural strength and tensile splitting strength, were determined for the used two-layers concrete pavement with exposed aggregate depending on applied Dmax.

Due to the nature of work, a bridge structure should comply with specific features and requirements. This article presents the results of the fatigue life of selected asphalt mixtures used in bridge structures. Mixtures for various pavement layers were investigated. The effect of high temperature on stiffness modulus and fatigue cracking resistance with different levels of strain were analyzed. These relationships were presented in the regression equations form. The crucial influence of increased technology temperature on asphalt mix fatigue life was proved.
The estimation of stereovision precision in road inspection
Authors: Staniek Marcin 
Published: June 2020

The estimation of stereovision precision in road inspection was determined by the analysis of the distribution of differences between measurements: the stereo vision method and the method of direct measurement with the use of laser distance meter. The carried out analysis is aimed at verifying the type of mapping error of a road surface. The input data was obtained from 160 measurement sections which feature both a different type and a different condition of road pavement.
The estimated method of road inspection is based on the stereo vision method of surface representation. Spatial representation of the road is obtained from the images recorded through taking stereo sequences of images by the measurement vehicle moving along the studied section of the road. The proper analysis of the image-based data and the application of mathematical transformations allow for determination of technical and functional parameters of the road. Spatial description allows for a precise evaluation of the state of a road pavement, which in traditional methods of image processing, without information about the depth, is difficult to be achieved and often burdened with errors of qualification of road distresses.
Vehicles speed analysis in roundabouts vicinity
Authors: Ziółkowski Robert 
Published: June 2020

Driving speed is one of the most important factors in road safety as it not only affects the severity of a crash but it is also related to the risk of being involved in a crash. One of the solutions for improving safety in cities is to design new and replace already existing crossroads by roundabouts which offer improved safety over other types of intersections having fewer conflict points, slower speeds and easier decision making. Previously conducted studies considering traffic safety at crossroads in Bialystok have confirmed lower number of accidents and casualties at roundabouts when compared to other types of junctions but at the same time the number of collisions remained at unexpectedly high level. The paper presents the survey of instantaneous speed, decelerations and accelerations in vicinity of chosen roundabouts located in Bialystok. The data was gathered by utilizing a portable wireless GPS data logger that allowed monitoring and recording second-by-second in-field vehicle position along the tested sections.

Preparation of a residential project in accordance with the expectations of a buyer requires from a developer a lot of experience and a good knowledge of housing market. Preferences of people looking for flats are very diverse, therefore, it is essential to know the factors which are taken into consideration when buying a flat. The level of flats sale and income gained from it depend on how much the offered flats meet the requirements of buyers. Understanding the flats buyers’ preferences requires a detailed study among potential buyers that aims at identifying the factors taken into consideration while choosing a flat and determining their influence on the made decision. In the article, the method is presented which supports a developer in making decisions regarding the development of a building concept in relation to design and material solutions, its location and making the offers of flats for sale more attractive.

We report a unique case of 23-year-old patient who developed late onset postpartum eclampsia complicated by PRES and acute kidney injury requiring renal replacement therapy. The case report emphasizes the need to continue antihypertensive medication in hypertensive parturients during postpartum period for at least 6 weeks as frequency of late postpartum eclampsia is high. The medication should be tapered off slowly to avoid reactive hypertensive episode which might trigger PRES and acute kidney injury.
