“…In order to evaluate the durability of SSA, Los Angles Abrasion (LAA) test was conducted based on TB/T 2328.1 and ASTM C535-96 (Table 3). The results indicate that basalt and steel slag abrasion resistance is in good agreement with the results of previous studies [14,35] and meets the requirement of the 4 Test results…”

The use of recycled material is a new tendency in the field of railway engineering. Steel Slag Aggregates (SSA) are one of the recycled materials derived from the steel industry. The application of SSA in ballasted railway tracks requires mechanical examination. In the present paper, the shear behavior of the ballast layer constructed by SSA and basalt aggregates was considered to assess the use of SSA as a substitution for basalt. In this regard, a series of large-direct shear tests were performed on basalt and SSA under various normal stresses. Based on the results, basalt aggregates have higher shear resistance than SSA for all normal stress. However, steel slag has sufficient shear strength as well as particle abrasion resistance. Overall, it was proven that the SSA has suitable stability against a shear forces that could be applied on railway ballast.

“…Kekec et al [7] studied the aggregate wear and came to the conclusion that the most wear-resistant rocks are rocks with high hardness, such as volcanic rocks. For example, Sweden and Finland decided to use porphyry to reduce abrasive wear of the coating, which are widespread in northern Europe.…”

The aim of the article is an improvement of abrasion resistance of materials of road pavements and giving practical recommendations during the pavement designing to the construction organizations. The Prall Test method was used to identify the factors influencing the wear resistance of asphalt concrete. Studied mixtures and materials are typical for the highway construction in the Russian Federation and the Republic of Tatarstan. The influence of such factors as the type of mix, the size of the aggregate, the type of binder and the quality of the aggregate was studied. The study shows that the increase of the wear resistance and coarseness of the aggregate when using a polymer-modified binder and the reduction of the content of air voids increase the wear resistance of asphalt concrete mixtures.
