The history and the basic research directions of Branch track testing research laboratory ofDnepropetrovsk national university of railway transport named after academician V. Lazarjan are given in the article.

This paper describes laboratory tests on a Leica AT401laser tracker. As the newer Leica AT402 model also uses the same firmware package, most of the results should also be valid for this device. First, we present the instrument’s firmware errors and the s... see more

Highway-railway grade crossings are an important part of the transportation system. It allows two types of vehicles to operate in the same areas. Researchers have previously studied the grade crossings, but research on the monolithic prestressed concrete ... see more

Millions of animals are used in research and toxicity testing, including in drug, medical device, chemical, cosmetic, personal care, household, and other product sectors, but the environmental consequences are yet to be adequately addressed. Evidence sugg... see more

Understanding the wave parameters in the ocean wave phenomenon is necessary to learn and develop the potential of ocean wave energy. Therefore, this study created a simple laboratory-scale of wave simulator that was developed using an electric motor. The ... see more

Linear air track is often used in physics learning for linear motion experiments because it can reduce friction between objects with trajectories. However,  the use of air tracks for motion experiments in schools often does not care about aspects of ... see more

This study aims to measure the performance of a mixture of Asphalt Concrete - Wearing Course (AC-WC) with addition of crumb rubber using a dry process, where crumb rubber as an aggregate replacement of fraction no. 50 with mixture variations of 0%, 25%, a... see more

Resilient modulus (MR) is a very important parameter for designing the flexible pavements. In the mechanistic pavement design, MR of pavement materials is used as an input parameter. In most of the studies, the MR values are usually obtained by conducting... see more
