Abstract: The article deals with the issues related to the properties of stone material included in asphalt concrete mixture as one of the main components determining the wear resistance of asphalt concrete. One of the most widely used stone materials is granite. At periodic impact of antiskid tire spikes on grains of granite crushed stone there is a gradual accumulation of damage, leading to the emergence and development of cracks, and further, the separation of granite particles from the grain (separate rubble), i.e. its wear. The model of interaction of an antiskid spike built into an automobile tire with a granite crushed stone grain is offered. With the use of methods of linear mechanics of destruction, by transformation of expression for the coefficient of intensity of stresses, ratios between strength of a stone material and quantity of cycles of loading on a grain of granite crushed stone before destruction are deduced. On the basis of the received ratios the estimations allowing to compare wear resistance of samples of granite crushed stone having different characteristics can be given.
Keywords: Asphalt concrete wear resistance, shear modulus, ultimate strength, stress intensity factor.

Abstract: The article presents the results of the first accelerated tests in Russia of two flexible road pavement structures (traditional and experimental) using the CYCLOS wheel load simulator. The studies were conducted on a test site in the Nizhny Novgorod Region and included a comprehensive assessment of stress-strain state, rutting resistance, temperature and humidity conditions, as well as the durability of the structures under cyclic loads. To monitor the parameters, sensors were used to measure deformations, stresses, temperature and humidity in different layers of the road pavement. Particular attention was paid to the testing methodology. The testing program included the application of 1.5 million loads, which made it possible to evaluate the durability of the structures in a short time. The presented study represents an important step in the development of domestic road science and practice, demonstrating the transition from laboratory tests to full-scale field studies using modern technologies.

Abstract: The article deals with the problem of assessing the technical condition of composite bridge spans, in particular, the detection of hidden defects associated with a decrease in the prestressing level of reinforcement. Existing methods, including visual and nondestructive testing, often do not allow for the effective detection of such defects that can lead to sudden structural failures. As a solution, a vibrodiagnostic method based on the analysis of the dynamic characteristics of spans, such as natural frequency, dynamic coefficient, damping coefficient and relative damping coefficient, is proposed. Results of dynamic and static tests demonstrating that changes in vibration frequencies indicate a reduction in the stiffness of the span structure and loss of prestress are presented. The proposed methodology of vibration diagnostics allows to promptly identify hidden defects and effectively assess the technical condition of bridge structures, minimizing time costs and simplifying the diagnostic process. The uniqueness of the method is determined by its easy integration into the current diagnostic processes of operating bridge structures, as well as by the absence of the need to carry out works on the opening of the structures and the prolonged closure of traffic during testing, which significantly increases the efficiency of the assessment of the technical condition of bridge structures and prediction of their durability. It is noted that vibration analysis can be used to assess the current technical condition of composite spans and to predict their durability, which is important in the development of recommendations for extending the service life of bridge structures.
Keywords: Vibrodiagnostics, static tests, dynamic tests, prestress, dynamic characteristics, span, bridge structures.

Abstract: The problem of insufficient illumination of roads in urban conditions increases the risk of accidents. Efficient and economical lighting is an important task for road safety. Reinforced concrete lighting poles are currently widely used, but reducing their cost and weight is an actual task. The use of cavities in reinforced concrete structures can reduce material consumption and product weight, but requires careful study of the impact on strength and reliability. The purpose of the study is to improve the design of typical reinforced concrete lighting poles by reducing their weight due to the formation of an internal cavity using plastic pipes. As a result of the conducted research, it was found that the use of plastic pipes as hollow formers makes it possible to reduce the weight of reinforced concrete poles of the SV type by up to 20 %. The optimal sizes of plastic pipes for SV 105 and SV 110 poles have been determined, ensuring the preservation of load-bearing capacity. It is shown that PVC and fiberglass pipes can ensure the integrity of the structure after the destruction of the reinforced concrete section. The proposed technical solution makes it possible to reduce the weight and cost of lighting poles, as well as to provide the possibility of laying communications inside the cavity. The results of the study can be used to develop new structures for reinforced concrete lighting poles.
Keywords: SV type support, cavity, reinforced concrete pole, pipe, stress-strain state.

Abstract: The article is devoted to the issue of using speed bumps on federal roads with no more than 2 lanes, passing through urban areas with a speed limit of no more than 60 km/h, based on the positive results of an experiment conducted in the territories of the Kabardino-Balkarian and Karachay-Cherkess Republics, as well as the Stavropol and Khabarovsk Territories. Based on the results of this experiment, the conditions that allow the use of speed bumps on federal roads are formulated. Currently, the applicable regulatory documents do not allow the use of speed bumps on federal roads. The proposals developed in the course of planned scientific researches to amend the regulatory documents to improve the rules for the use of speed bumps will ensure increased road safety and reduce the risk of pedestrian collisions on sections of public federal roads passing through urban areas.
Keywords: Speed bump, road safety, forced reduction of traffic speed, experiment, road user, traffic accident, hitting a pedestrian.

Abstract: The article presents the results of a laboratory study of the influence of the composition of cement concrete mixture on the abrasion index Gpt of cement concrete pavement. The mineral part in the concrete mixture significantly affects the strength characteristics, as well as such an operational indicator as abrasion Gpt, which plays an important role in assessing the resistance of the pavement to abrasion by studded tires. To test this hypothesis, concrete mixtures were used, selected on different materials with their different ratios. Based on the results of the selection of concrete mixtures, tests of the concrete mixture and concrete were carried out to determine the technological, strength and operational characteristics. Based on the researches, conclusions were made about the influence of the method of laying the concrete mixture, the genesis of the large coarse aggregate and the granulometric composition of the mineral part on the abrasion index Gpt.

Abstract: The article examines the effectiveness of using geosynthetic materials that perform the function of separating layers of unbound mineral materials in road pavement structures. An analysis of the current regulatory and technical framework, as well as scientific publications focused on the role of geosynthetics in preventing intermixing between adjacent layers, is presented. Based on laboratory and full-scale field tests, it has been established that the use of geosynthetics separating layers significantly reduces the depth of particle interpenetration, ensures the preservation of the design characteristics of the pavement structure, and enhances its operational reliability. The economic analysis confirmed the feasibility of using geosynthetics by demonstrating cost savings by reducing overconsumption of aggregates. The obtained results complement the available scientific data and justify the inclusion of the separating function of geosynthetics in design solutions for road construction and reconstruction.

Abstract: Plastics are widely used in various aspects of everyday life. Polyethylene terephthalate (PET) dominates the global plastic recycling market, accounting for about 55 %. Without effective management methods, a significant amount of generated plastic waste (PW) can cause global environmental problems. To solve these problems, three main areas of application of recycled polyethylene terephthalate (rPET) waste are considered in foreign practice in the field of road sector: as plastic auxiliary and structural elements of the road; in the production of geosynthetic materials; as part of hot asphalt concrete mix. Modern researches confirm the prospects of using rPET as part of asphalt concrete mixes. Particular attention is paid to the development and implementation of the most effective technologies with mandatory compliance with the key condition: their use should not worsen the performance characteristics of roads. In order to raise the level of information awareness of participants involved in the circular economy, the article provides a modern analysis of foreign experience in the use of rPET and the possible area of its application in the road sector.
Keywords: Resource conservation, plastic waste (PW), polyethylene terephthalate (PET), recycled polyethylene terephthalate waste (rPET), bitumen and asphalt concrete mixture modification.
