The development of a country's economy largely depends on the pace and efficiency of construction work, which, in turn, is determined by the extent to which innovative technologies and techniques are used. This work is devoted to justification of the basic parameters and the development of a new working body for a machine for cutting joints in road surfaces. A design with cycloidal motion is proposed, which intensifies the destruction process due to the vibrational impact of the cutters on the material being processed. The use of such a working body provides a vibrational effect, increases the cutting speed, and reduces the energy consumption of the process. As a result of intensifying the interaction between the working body and the material, it was possible to reduce the energy consumption of cutting by 1.13 times, and increase productivity by 1.18 times compared to analogues.DOI

In this study was addressed a pressing scientific and technical challenge involving the justification of design parameters and the development of a working component for a slot-cutting machine with cycloidal motion. Based on the theoretical and experimental data obtained, the following main conclusions were drawn: 1. Scientific findings: It has been established that the use of the cycloidal motion principle (movement of the cutters along a hypotrochoid) enhances the process of asphalt concrete fragmentation through the vibro-impact action. The theoretically derived dependencies of the cutting force (Equations (1) (4)) have been experimentally confirmed with a correlation of 85%, which proves the adequacy of the proposed mathematical model of the working process dynamics. 2. Technical and Economic Efficiency: A comparative analysis of the developed design with existing counterparts (DFM-40, DFM-64) demonstrated a significant advantage of the proposed method. The use of a cycloidal cutting tool reduces the energy consumption of the cutting process by a factor of 1.13 and increases productivity by a factor of 1.18. Under optimal operating conditions (n = 150 rpm), a reduction in cutting force to 30 kN was recorded, compared to 45-50 kN in conventional machines. 3. Practical significance: The results of this study can be applied in the design of new models of the road construction equipment, specifically the ZRM-1 expansion joint cutting machine. The implementation of this technology would improve the quality of the expansion joints cut and reduce operational costs in the construction and repair of highways in KazakhstanКвартиль
