Title of the articleCutting technological holes in the road surface
Abstract.Problem statement. The aim of the work was to optimize the workflow process when cutting holes for the hatches in the new pavement and repair of road surface under hatches subsidence on the basis of the use of more universal equipment, allowing to cut any working geometric forms that are necessary for carrying out the installation or repair work. Results. Proposes a draft of equipment able to cut holes in the road surface sufficiently of accurate size, of different geometric shapes, without damage to the environment and the notable economic effect. Analyzed the technology and equipment of famous foreign manufacturers widely used in the road sector of the Russian Federation. Their advantages and disadvantages identified. Based on the analysis a better way of cutting technological holes in the road surface with the use of the proposed equipment was offered. Conclusions. Developed a design of a proposed equipment. Described the features of its application. We calculated the relative economic efficiency of the implementation of the proposed technology and development. It is found that the introduction of the proposed technology and equipment for cutting the technological holes is more cost-effective (~ 24 %) compared with the current production of foreign counterparts.
