“…All this leads to the fact that defects (cracks, spalling, potholes, corrosion) are formed in engineering structures. With the timely detection and elimination of defects, the service life of the structure does not change [11,15,16]. Unfortunately, at linear construction facilities it is impossible to organize work on continuous monitoring and diagnostics of such elements as road pavement, culverts (reinforced concrete and metal), elements of bridge crossings, guardrails, which leads to the formation and untimely elimination of defects.…”

“…However, the studies of the operational reliability of road pavements were carried out only for the European part of the country, Europe and the southern territories of the United States, where the climate is milder and there are no large temperature differences [14,18,21]. The analysis of statistical data on determining the rate of crack formation on a newly repaired pavement showed that "reflective" cracks appear on the pavement in the period from 1 to 6 months, and the intensity of crack formation depends on the intensity of the traffic and climatic conditions [15]. Defects such as cracks, spalling, potholes, spading and corrosion are eliminated nominally either by sealing the defect with a new material with similar properties, or by physical destruction of a part of the structure followed by filling with a similar material.…”

“…Principal stresses and relative strains are calculated using the formulas of the theory of stresses and strains in continum mechanics. Average stresses and average relative strains are calculated by the formulas (15) (16) where σ 1 , σ 2 , σ 3 and ε 1 , ε 2 , ε 3 are the components of principal stresses and relative strains. In the simulation model, the crack depth in the bottom layer of a two-layer asphalt concrete structure is 3 cm with a width of 4 mm.…”

The paper considers the issues of crack resistance of multilayer systems made of asphalt concrete, namely: the causes and features of the occurrence and development of "reflected" cracks are investigated. A study of the operational state of highways was carried out and the prerequisites for the formation of defects on the pavement were determined, including the regional features of the work of the road structure. The authors comprehensively studied the causes of internal and external defects and deformations of asphalt concrete pavements. The most popular technologies for sealing cracks and restoring the pavement are considered, the experience of repairing roads in the western part of Russia, Europe and the USA is also investigated. The results of determining the rate of formation and development of defects in the surface of the exploited roads are presented. In laboratory conditions, work was carried out to simulate cracks in two-layer samples of fine-grained asphalt concrete. Test specimens with a height and diameter of 10 cm were made by molding and compacted in layers, a crack was laid in the lower layer of the specimen. After gaining strength, the samples were tested for compression. Analysis of the results of physical modeling made it possible to put forward an assumption about the existence of a relationship between the presence (absence) of internal defects in the coating and the strength of the structure. To confirm the hypothesis, mathematical modeling of the operation of a two-layer system in the GenIDE32 software package was performed. Evaluation of the stress-strain state by the finite element method showed the presence of characteristic zones of system weakening around the defect area. In a two-layer system, there is an increase in internal stresses and strains around the crack, as well as a decrease in the overall strength (stability) of the system. In conclusion, the influence of internal defects of asphalt concrete coatings on the process of formation of "reflected" cracks were identified.

“…In the literature, can be found reports on the improvement of the quality and safety of road traffic and the assessment of the quality of road surface repairs. Kamenchukov et al (Kamenchukov et al, 2018) have developed a method for the integrated assessment of the effectiveness of road surface repairs, which makes it possible to define actions aimed at restoring the appropriate road properties, depending on the conditions of its operation. According to the method, each of the repair methods proposed by the engineers is assessed in terms of economic benefits, which makes it possible to select the most optimal technique, while avoiding high costs.…”

In recent years, numerous measures to modernize local roads in rural areas have been undertaken. Unfortunately, during renovations, especially at the poviat and commune level, errors are often made as a consequence of irregularities arising at the design stage. The article presents an assessment of the quality of local road renovations carried out in the last fifteen years, in the context of maintaining operational parameters over time, using a visual method based on the term “risk”. The research was carried out for twenty-six sections of roads that were renovated or rebuilt in the Kłobuck and Częstochowa poviats. The categories of the most common errors were identified and actions were proposed to correct them and prevent new ones. Among the negative trends, the improper placement of road technical devices and the lack of appropriate marking of integral areas were distinguished. It was found that a positive aspect in the aspect of traffic safety, recently, is the widespread use of modern road marking systems and road signs, as well as greater care for proper maintenance of drainage devices. The use of modern solutions during the modernization of roads, despite co-financing from the Government Fund, is still limited by the financial deficit of local governments.

“…Construction schedule optimization is a challenge for those agencies in charge of pavement maintenance and related operations. Several researchers proposed solutions to schedule optimization through different methodologies and addressed specific aspects such as equipment aging and efficiency ( 1 – 3 ), best practice analysis ( 4 ), and sequencing factors and activity interdependency ( 5 , 6 ), and resource locations ( 7 ). Arditi and Albulak ( 8 ) proposed the Line of Balance method derived from Linear Scheduling in highway projects and concluded that such methodology, although efficient as a scheduling technique, was greatly affected by misquantification of crew size and overall activity duration.…”

Transportation infrastructures are essential for supporting any community activity, from economical function to emergency services. The importance of maintaining the infrastructure in serviceable conditions must be evaluated in relation to the impact that maintenance activities may induce to the communities served by roadways. Pavement repair is composed of different activities characterized by time, efficiencies, performance, and personnel availability, and the optimization of such activities can definitely limit the impact on the overall roadway service. The methodology proposed in this study is centered on fuzzy reasoning and aims to quantify the repair rate and, therefore, the impact of the overall activity. As in the examples proposed in the analysis, based on the repair size and thicknesses, road classification, and traffic, the maintenance agency has the possibility of making a sound choice in road closure or establishing a detour for a limited period of time. Combining the model results with additional knowledge about the repair location and roadway service level at the moment of the repair, agencies have the ability to reassign equipment, crews, or other element, with the objective of minimizing the construction activity impact on the community. The model’s results are promising; successive steps consist of tailoring such a model with each agency-specific scenarios, equipment fleet and related performance, crew skill level, and lastly, roadway network configuration.
