The article presents the results of studies of innovative materials in the field of testing frost resistance. In fact, present accelerated methods for the determination of concrete frost resistance have high labour consuming and low effectiveness. Moreover there is no such accelerated methods which can be sufficiently applicable fro different innovative concretes, for example, concretes with SAP or self-compacting concrete and so on. Therefore, it is highly important to investigate new accelerated test method with high operability, efficiency and sufficient precision. Previously, two new methods were developed. The main purpose of the research is to compare these methods by evaluation of their technology and accuracy and, consequently, to identify the more sustain and efficient one. First method is based on estimation of energy release due to mechanical fracture and thermo cycling. Second method consists of the calculation value z (relation between relative decreasing of strength and relative strain in the direction perpendicular to compression) and replacement of thermo cycles by mechanical cycles. Both methods have high operability and do not take a lot of time, in was tested on the 10 specimens made of concrete and results were compared with values derived by standard method.

The object of research in this article is culverts, namely the technology of their construction. This topic is relevant in connection with the development of road construction, which in turn requires high-quality drainage, carried out in most cases by culverts. The purpose of the study is to select and justify the most rational method of construction of culverts on roads and Railways. The article analyzes the advantages and disadvantages of the method of pushing finished links into the embankment. Various variants of pipes used in this method are considered, and the most suitable material and shape are selected. The features of operation of newly constructed culverts in the first year of their service are highlighted. The result of the study is a proven advantage of the method of pushing finished links into the embankment, namely, using round-shaped pipes made of the most suitable material for performing these works-corrugated iron.
