Currently, the market for the road rollers production is actively developing. Each manufacturer has its own production experience and uses a developed approach to the new models design. The difference in design technologies leads to the emergence of a significant number of road rollers new models on the market. Practical studies of the roller drum interaction with hot asphalt mix show that many models with different structural parameters have a similar effect on the compacted material. Therefore, it is necessary to develop a universal approach to the choice of design parameters of rollers in their production. The paper attempts to develop a general methodology for determining the design parameters of rollers. For this purpose, a design parameters statistical analysis of more than 260 models of road rollers of leading manufacturers was carried out. The analysis results are presented in the form of a choice nomogram of road roller parameters. Taking into account the received nomogram it is possible to carry out the comparative analysis of rollers various on constructive parameters on the indicator of efficiency offered in work. The proposed algorithm allows us to recommend design parameters when designing new models of road rollers by manufacturers. As a consequence, it is possible to reduce the number of similar models of rollers.
