“…In any case, the most popular approach proposed different algorithms for different speeds [19,24,[39][40][41], effectively making the proposed systems very difficult to apply in the different road context because the difference in variable and procedure are strongly dependent on the road type (e.g., rural or urban), either in reference to standard indicators (e.g., IRI) or by means of specific indicators [42][43][44]. The same results appear in reference to the classification of distress carried out using a machine learning approach.…”

Road pavement monitoring represents the starting point for the pavement maintenance process. To quickly fix a damaged road, relevant authorities need a high-efficiency methodology that allows them to obtain data describing the current conditions of a road network. In urban areas, large-scale monitoring campaigns may be more expensive and not fast enough to describe how pavement degradation has evolved over time. Furthermore, at low speeds, many technologies are inadequate for monitoring the streets. In such a context, employing black-box-equipped vehicles to perform a routine inspection could be an excellent starting point. However, the vibration-based methodologies used to detect road anomalies are strongly affected by the speed of the monitoring vehicles. This study uses a statistical method to analyze the effects of speed on road pavement conditions at different severity levels, through data recorded by taxi vehicles. Likewise, the study introduces a process to overcome the speed effect in the measurements. The process relies on a machine learning approach to define the decision boundaries to predict the severity level of the road surface condition based on two recorded parameters only: speed and pavement deterioration index. The methodology has succeeded in predicting the correct damage severity level in more than 80% of the dataset, through a user-friendly real-time method.

“…[14][15][16][17][18][19] have had valuable results on their explorations that are associated with analysis of influences on as-built pavement roughness in asphalt overlays at long-term pavement performance test sites, as well as determining the road surface and weather conditions that have a significant impact on the traffic stream characteristics. On the other hand, effects of vehicular speed on assessment of the pavement road roughness have been studied by other researchers [20][21][22][23][24]. As a result, the topic continues to be authentic by influencing its effect on other case studies.…”

ResumeResults of the study of the roughness and friction properties of the road surface of urban streets influence on the traffic safety are presented in this article. As a result of this study, an empirical dependence was obtained, reflecting the relationship between the traffic speed and a load factor under different traffic conditions; the relationship between the flow density and street capacity was also determined. The maximum permissible value of the friction coefficient for experimental streets is 0.4, and 50 % of the object of study meets the requirements of operation; 50 % does not. From the proposed graph of the relative dependence of pavement roughness and safety factor, it follows that the most dangerous are the streets, the pavement roughness of which is in unsatisfactory condition. To effectively solve the problem of destruction of the road surfaces, it is first of all necessary to eliminate the cause of the damage that occurs, not just its consequences.

“…This is at least partially because the cement does not bond well with the pieces of rubber, so they're not held together firmly enough [2] Concrete with rubber mixture has the capacity to withstand wear and tear, making it an excellent choice for high-traffic areas such as gyms and track fields, which are typically built with durable materials to withstand the rigors of intensive usage. Also, wear and tear resistance can affect the road roughness [3,4]. Furthermore, concrete's resistance to abrasion can be increased by adding tire rubber particles, making it ideal for use in pavement, floors, concrete highways, and other applications where there are abrasive forces between surfaces and moving objects [5].…”

In recent years, rubber consumption has surged due to factors like global automobile industry growth, infrastructure development, industrial expansion, and the push for a circular economy. This research investigates the impact of incorporating waste rubber as a coarse aggregate substitute on concrete's compressive strength. This addresses concerns about rubber waste disposal and its potential as a sustainable construction alternative. Experiments vary rubber proportions (0%, 2%, and 5%) in concrete mixes to assess compressive strength. The results indicate that using rubber as coarse aggregate reduces concrete's compressive strength, Therefore having an amount of less than 2% is the best performance of the optimum rubber proportion. This is because rubber lacks chemical reactivity with cement during hydration, resulting in poor adhesion and bonding. This highlights the limitations of incorporating waste rubber in concrete mixes, cautioning against its use in high-stress structural areas. Engineers and architects interested in sustainability and innovation in construction should consider these findings, as they have practical implications for the industry.
