###### Abstract  
The transport infrastructure's pavement is made of asphalt layers, placed and compacted. The asphalt mixture is produced in an asphalt mixing plant (AMP) using expensive technological equipment which, when it becomes obsolete and worn out, is replaced with new equipment. One of the main problems related to the replacement process is that when it comes to purchasing new AMPs, the decision making involved is, in most cases, highly intuitive due to a lack of clearly defined criteria. In order to remedy this situation, this work presents an analysis of the correlation between the number of AMPs and the production of asphalt mixtures. Firstly, a correlation analysis was performed based on the European Asphalt Pavement Association (EAPA) data. Secondly, the current situation with the AMPs in European countries was analysed. Furthermore, a case study was performed and a system of nine criteria was created to identify why/when road construction companies operating in the Baltic States buy new AMPs. The weights of the criteria have been established by applying the Analytic Hierarchy Process (AHP) method. It was found that the most important criterion during the decision-making process for road construction companies is increased requirements for improving the quality of the asphalt mixture produced (criteria weight 25.0%). With a weight of 20.6%, the second vital criterion is the possibility of receiving support from European funds. The third criterion is the expectation of having a sizeable asphalt-paving site (weight 20.4%). The other six criteria are also significant, their weights varying between 1.6% and 13.5%. The industrial companies can use the obtained results for designing, producing and selling AMPs and adjusting strategic business plans. s 1 (2021) 5 October 2021 9  
technological operations, the hot aggregate fractions, IF with RD, hot bitumen and RAP are dosed into the mixer using separate scales. The primary operations of forming the structure of the asphalt mixture are carried out in the AMP mixer. The bitumen is transformed from the volumetric state into films covering all the particles. The different-sized mineral particles are evenly distributed in the asphalt mixture. The asphalt mixture produced in the rotating mixer is handled into a truck or a storage silo. All the technological operations during the asphalt mixture production process and their parameters will have an impact on the quality of the asphalt mixture as well as the structure and properties of the asphalt pavement. During the production of the asphalt mixture in the AMPs, the production costs and environmental pollution need to be minimised. However, at the same time, the technological universality and reliability of the AMPs should be increased. Each country has a certain number of AMPs capable of producing a specified amount of asphalt mixture. This amount depends on the available investments in road construction, the intensity of the road network development, the AMP mixing capacity, the climate and weather conditions. Due to unavoidable wear of AMPs, stricter requirements for the quality of asphalt mixtures and ambient air pollution, the old equipment in the AMPs is replaced with new equipment or new AMPs are installed on new sites. As the manufacturers of AMPs can produce any device that meets the needs of a potential buyer, the decision to purchase a new AMP must be made very responsibly. However, one of the main problems is that AMPs are usually bought very intuitively, without a clearly defined fleet renewal strategy. Thus, this paper describes the adoption of a scientific approach while seeking to define the most important criteria for the AMPs' fleet renewal strategy. The obtained results can be used by the stakeholders, such as business companies and public authorities, to fill the gap addressing the AMPs' fleet development issues. Respectively, the research framework diagram of this study is shown in Figure 1. From the provided diagram it can be seen that the research was performed in three main steps.
