This scientific article presents an analysis of the norms roughness road pavement in foreign countries. Based on results obtained from experimental research work measuring international index (IRI) pavements many years various highways by studying their experience, Republic Uzbekistan are recommended.

Pavement roughness is a critical airport pavement characteristic that has been linked to impacts such as safety and service life. A properly defined evaluation method would reduce operational risk, prolong the life of aircraft landing gear, optimize decision-making process for preservation, which together positively contribute overall sustainability. In this study, we optimized parameters Inter...

Condition assessment of pavement has a predominant part in delivering safety and comfort to users. Roughness is considered the most important characteristic as it affects road vehicle operating costs. Authorities spend significant quantity resources on using conventional methods for measuring roughness. Many researches are performed estimate roughness by deploying smartphone sensors. However, n...

In this paper, we test whether an autonomous robot can be used to measure the International Roughness Index (IRI), a description of pavement ride quality in terms of its longitudinal profile. A ready-made robot, the Pioneer P3-AT, was equipped with odometers, a laptop computer, CCD laser, and a SICK laser ranger finder to autonomously perform the collection of longitudinal profiles. ProVAL (Pro...

Abstract With the development of science and technology, intelligent pavement smoothness detection becomes possible. Intelligent IRI (International Roughness Index) is one important directions performance detection. Different from traditional detection, uses smart phones to collect traffic vibration data. There are many indexes in evaluation unit driving data, can be realized by extracting inde...

Pavement evaluation is the most significant procedure to minimize degradation of pavement both functionally and structurally. Proper hence required prolong life year pavement, which thus needs be addressed in policy level. By this, development genuine indices are formulated used for evaluation. In context evaluating measuring roughness, International Roughness Index (IRI) used, whereas calculat...

During last decades, owing to the increase in a number of vehicles, the rate of accident occurrence grows significantly. Efforts must be made to provide efficient tools to prioritize segments requiring safety improvement and identify influential factors on accidents. This objective of the research was to determine the safety oriented threshold of International Roughness Index (IRI) to recognize...

Pavement condition largely determines its long-term behavior and is of paramount importance for rehabilitation maintenance management. The use non-destructive testing (NDT) systems to assess pavement has gained much popularity. Often, well-known NDT are combined take full advantage the capabilities each system. Combining independent optimize assessment process a scientific challenge. With this ...
