Road agencies around the world note the aging of the national road network and the accelerated destruction of pavement during operation due to changes in the composition of the traffic. Many scientific studies have noted that cracks of various configurations, depths, origins are the most characteristic type of pavement damage, make up a significant part of the total area of destruction and are the main danger as the initial stage of more serious damage leading to loss of pavement distribution. Timely detection of hidden cracks in the coating layers and the base layers allows to prevent the destruction of pavement and significantly reduce the cost of road repairs. The purpose of the article is to analyze the methods and criteria for assessing the condition of non-rigid pavement, which contains hidden defects in its structural layers. The results of the analysis make it possible to take into account a particular type of defect when choosing a calculation scheme and the order of calculation of pavement. The analysis proved that the calculated schemes of pavement design do not allow to take into account such indicators of pavement condition as the number of cracks, their position, geometric parameters of hidden cracks, sizes of cracked base blocks, volumetric damage of the layer material. The assumptions and simplifications accepted in the normative documents actually make it impossible to assess the condition and predict the failure of the design of paved roads with cracks. Therefore, the assessment of the condition of non-rigid pavement should be based on probabilistic methods and criteria for assessing the condition of pavement, which allow to take into account the heterogeneity of pavement design, due, inter alia, the presence of cracks in layers of monolithic materials. The next stage of research is the analysis of existing probabilistic methods of designing and assessing the condition of pavement.

Pavement Condition Index

Bogasari Road, which is located in Citeureup sub-district, Bogor Regency, within the PT Indocement Tunggal Prakarsa industrial area, is a road that uses rigid pavement. The road is always passed by heavily loaded vehicles that affect road pavement conditions and the level of comfort and safety for road users. The study's purpose is to determine the average daily traffic volume, determine the value of conditions in the rigid pavement, and provide input to relevant agencies in terms of solutions and road repair costs. The method used in the analysis is the Pavement Condition Index (PCI). The study shows the average daily traffic of 2,883 vehicles/hour/day and the average pavement condition value of 66.57 with a good rating, or in good condition. It also provides a method of repair by functional means.

ASTM D6433 is used to assess the need for maintenance of pavement sections. Although the Pavement Condition Index (PCI) factor calculation method provides reliable values, this method analyzes sections and defects individually and indicates current maintenance needs, but it cannot be used to predict the occurrence of new defects. Therefore, it is necessary to complement this method by considering variables that influence the occurrence of faults, among which are the geospatial distribution and the specific characteristics of the slabs. This research focuses on the identification of multiple types of disturbances that exist in Portland Cement Pavements (PCC), located in a high traffic area in the city of Valdivia (Chile). A spatial geostatistical relationship is established through visual inspection using geographical maps, as well as distribution, using the kriging method. This technique makes use of variograms that allow quantifying the parameters used in this study, thus expressing the spatial autocorrelation of the faults analyzed. From the results obtained by spatial geostatistics and kriging, it is possible to generate a data correlation for the distribution and characteristics of the streets considered. In addition, a co-kriging method is established instead of an ordinary kriging method. The relationship between observed and predicted values improved from 0.3327 to 0.5770. The width of the slabs, as well as some streets, is shown in our analysis to be unimportant. For better model accuracy, the number of covariates associated with the type of vehicle traffic, the age and shape of the slabs, and the construction techniques used for the pavement needs to increase.

Pavement Structures

Rigid pavement structures are one of the costly components of the infrastructure development process. It consumes a huge quantity of ingredients necessary for concrete development. Hence, a newly introduced concept of circular economy in combination with waste management was introduced to solve this problem. In this study, three waste products (rice husk ash (RHA), wood sawdust (WSD), and processes waste tea (PWT)) was utilized to develop the concrete for rigid pavement structures by replacing the sand, i.e., a filler material at different percentages. During the testing procedure of compressive (CS), tensile (TS), and flexural strength (FS) properties, RHA and WSD at 5% replacement were found to be a good replacement of sand to develop required concrete. This study will help in the production of eco-friendly rigid pavement structures and a pathway of life cycle assessment in the future.
