| Title of the article | Asphaltic concrete for road works based on low-quality crushed stone, reinforced with sulfur |
| Abstract. | Problem statement. The aim of the work is the development of effective road asphalt based on crushed stone from low-strength unclaimed mineral rocks of sedimentary origin. Results. Based on low-quality crushed stone from sedimentary rocks, a high-strength construction crushed stone of grade M1000-1200 was obtained, by its surface treatment with a melt of sulfur. It is established that crushed stone has a number of positive properties: hydrophobicity, a relatively high brand of crushing and frost resistance, low water absorption. As a result of the interaction of the asphalt binder with the surface of the gravel particles, a gradient layer is formed at the interface, which increases the cohesive strength of the asphalt concrete structure. It is established that asphalt concrete on the basis of reinforced rubble meets the requirements of GOST. Conclusions. The organization of industrial production of crushed stone treated with sulfur and asphalt concretes on its basis would allow reducing the amount of direct costs for the purchase of high-strength crushed stone and from igneous rocks and its transportation, reduce the estimated cost of construction and repair of highways. |
