“…In order to evaluate the performance of an asphalt layer, several [ 65 , 66 ] performed a numerical analysis on an asphalt layer under a high-speed railway and concluded that the optimal location of the asphalt layer is under the ballast and over the subgrade, which will lead to a higher bearing capacity in the track bed. Moreover, in order to decrease construction costs, a specific asphalt mortar pouring method with a long pipe was recommended for a line located in a snowy region of Japan [ 67 ]. In terms of construction cost, a research study on Spain’s high-speed railway track revealed that in many cases, the construction costs of tracks with a bituminous sub-ballast were similar to tracks with an all granular sub-ballast [ 68 ].…”

Asphalt is a common material that is used extensively for roadways. Furthermore, bituminous mixes have been used in railways, both as asphalt and as mortar. Different agencies and research institutes have investigated and suggested various applications. These studies indicate the benefits of bituminous material under railways, such as improving a substructure’s stiffness and bearing capacity; enhancing its dynamic characteristics and response, especially under high-speed train loads; waterproofing the subgrade; protecting the top layers against fine contamination. These potential applications can improve the overall track structure performance and lead to minimizing settlement under heavy loads. They can also guarantee an appropriate response under high-speed loads, especially in comparison to a rigid slab track. This review paper documents the literature related to the utilization of asphalt and bituminous mixes in railway tracks. This paper presents a critical review of the research in the application of asphalt and bituminous mixes in railway tracks. Additionally, this paper reviews the design and construction recommendations and procedures for asphalt and bituminous mixes in railway tracks as practiced in different countries. This paper also provides case studies of projects where asphalt and bituminous mixes have been utilized in railway tracks. It is anticipated that this review paper will facilitate (1) the exchange of ideas and innovations in the area of the design and construction of railway tracks and (2) the development of unified standards for the design and construction of railway tracks with asphalt and bituminous mixtures.

“…From the connection of life-time cost and the working life, the lifetime of the superstructure was increased by 17% [37]. Furthermore, the noise levels of slab tracks are higher than tracks on asphalt pavement under train running [31]. The various hot mix asphalt is also good in damping vibrations [6,45].…”

Purpose. The authors' aim is to summarize the results of relevant international publications and, based on these, to give a comprehensive review about the modern ballasted tracks' substructure. Methodology. This article is a start of a PhD research, which means it was proceeded by a secondary research. At first, the substructure and its protection layers were summarized, after that the geosynthetic cementious composite mat materials, especially the Concrete Canvas are discussed. Findings. The experiences of the geosynthetics' and other protection layers' functions, show that a possible using of the GCCM (geosynthetic cementious composite mat) under the ballast can be a good solution for renewing short sections in the railway tracks. Originality. One of the authors-namely Balázs Elleris a PhD student at Szechenyi Istvan University in Gyor (Hungary). His research topic is the reinforcement possibilities of railway substructure with the usage of special (mainly cement-bonded) layers. This article was written to collect and summarize the up to date knowledge related to modern ballasted railway tracks' substructure to be able to determine the following research ways and possibilities at this topic. The research plan will be sentenced in the near future, as well as the required laboratory and field tests will be prepared. Practical value. As expectation, after having executed the related research, the advantages and disadvantages of GCCM layers in the railway substructure will be able to defined, as well as factual deterioration process can be determined related to the ballasted tracks and their geometrical stability.
