Abstract

Problem Statement. Observation of the performance of objects restored by cold recycling technology shows that more attention should be paid to diagnosing the condition of existing pavement and predicting the processes that cause premature deterioration. Purpose. To find solutions to clarify the condition of the existing pavement and to determine in more detail the factors of deterioration. Research methods. Analytical and experimental with the use of computer modeling. Conclusions. Based on the results of the research, an algorithm for conducting the survey was developed, which consists of two consecutive stages. This algorithm is based on the results of the first stage of the survey that provides that not only data are collected, but also envisages that a program for the second stage of the survey is drawn up. Based on the results of the second stage of the survey, a plan diagram of the same type of road sections is formed, the need for additional preparatory work to eliminate local areas with deterioration is determined, and constructive and technological solutions for the repair of pavement using cold recycling technology are developed with the determination of the depth of milling, the amount and composition of stone materials that are additionally added to the mixture, the composition of the binder, etc.
