  • Patent number: 4152185
    Abstract: A railroad tie spike hole plugging material and method of using the same. The material includes a substantially uniform mixture of about 25-75% by volume of a granular abrasive material having a grit size in the range of about 20-100 grit and abrasive to railroad spikes, and about 25-75% by volume of a granular plastic material having a grit size of about 100 grit or less and a plastic temperature in the range of about 120.degree.-350.degree. F. The material is poured into a hole in a tie and when a spike is driven into the hole, the friction between the abrasive material and the spike generates sufficient heat to plasticize the plastic material. Upon cooling, the material firmly grasps the spike.
