Analysis of existing methods for assessing the quality of adhesion between layers of roadwear

Liydmyla Levkivska І. Hrynchak J. Elallak

This article is devoted to the study of the quality of adhesion between the asphalt concrete layers of pavement. It is established that the lack of effective methods and appropriate modern equipment or devices does not allow to control the quality of the road structure and affect the composition of the asphalt mixture in the design of pavement in order to improve its technical characteristics. The purpose of the work is to analyze the existing methods, devices and equipment for assessing the quality of adhesion between asphalt concrete layers during shear in the construction of pavement. Research methods - theoretical and experimental. The analysis of the factors influencing interlayer tangential stresses and deformations and leading to loss of stability at shift on highways of Ukraine is carried out. A literature review of data on existing analytical and experimental methods for estimating adhesion during shear between asphalt concrete layers has been carried out. Based on the results of research, taking into account climatic conditions and load parameters from modern vehicles, it is possible to further substantiate the parameters of the optimal method of determining the quality of adhesion between asphalt concrete layers of pavement and develop an automated device to determine it. The results of the work are recommended to be used for quality control during the construction and operation of asphalt concrete layers of pavement. Scope - construction and operation of public roads. Socio-economic efficiency of work is to increase the durability of roads, which will reduce operating costs, increase track stability and road safety.
