Abstarct: Abstract : With the increasing population in cities, the surface vibrations created by human activities have increased, which include heavy traffic, railway lines, explosions, construction, industrial machinery, etc. . These vibrations spread to a considerable distance, which causes disruption in the functioning of vibration-sensitive devices, even the gradual destruction of structures.. Due to population density, this distance from the source of vibration to the considered areas is very small and will have a significant impact. In order to prevent the spread of these vibrations, different methods of seismic isolation can be performed. On the other hand, the increase in population causes an increase in waste production, which itself is a big environmental problem. The large volume of produced waste, especially in areas where there is no proper landfills, is a short distance from residential areas, which endangers the health of the people of that area. One of the solutions to this problem is the recycle of dry waste. A part of this dry waste is covered by worn tires, which is very bulky. In this research, active insulation in the foundation bed of machines using a mixture of worn tires and sand with different ratios was investigated in a laboratory manner. In the physical test box, the ground of the car was immersed in a mixture of rubber and sand with a thickness of 5 cm so that this mixture is an obstacle for the propagation of waves. Using the insulating mixture of rubber crumb and sand in weight ratios of 10, 20 and 30%, they reduced the wave acceleration by 47, 62 and 72%, respectively, compared to the reference state without insulation. ‌
