STUDY OF DURABILITY OF ASPHALT MIXTURES USING THE CANTERPRO TEST

Abstract

Given the great importance of roads being one of the main projects in the countries, and through the development campaigns that the roads witnessed through paving projects, and by observing the materials used, a number of cases of collapse and failure of some roads were observed, which requires taking appropriate measures to avoid these damages, including an evaluation of some roads. This paper aims to study the possibility of improving the performance and durability of asphalt mixtures and reaching mixtures that have a continuous and acceptable performance under the influence of repeated axial loads and are resistant to various weather factors such as moisture, freezing, thawing, and heat, which may be exposed to during the investment life. The loss of durability, or what is known as the aging of asphalt mixtures, is the most common problem of flexible paving. For this reason, we studied the effect of repeated loads on asphalt mixtures through Marshall samples, with the aim of a better understanding of durability, its conditions, and requirements, and in order to reach high durability of these mixtures. In this paper, these results were analyzed and arrived at Finding results through which a good evaluation of a number of implemented asphalt methods can be made, and through which it is possible to judge the quality of these mixtures.
