ABSTRACT:
In a railroad track bed an injected layer is formed between the railroad ties and the roadbed so as to protect the latter. The injected layer is composed of an injection material injected through openings formed in the tie. The injection material has a viscosity below 30 poise at a temperature not higher than 200.degree. C. before hardening, and when hardened it has a compressive stress at 10% strain of 0.4 to 30kg/cm.sup.2 at a compressive strain rate at 40.degree. C. of 1.5% per minute.
