the difficulty of safe disposal of hazardous wastes and particularly of low and intermediate level radioactive wastes is well recognized. In most cases it involves relocation of waste from one residential or industrial site to another, which is usually located in close proximity to the built -up areas. The paper proposes a new method of "highway construction-waste disposal" of hazardous wastes, which should guarantee not only a long term safe removal of harmful materials, but also a significant improvement in the long term maintenance with defect-free surfaces of highway pavements. The history and practical development of special high durable concrete is founded on the principle of thermodynamic systems far from equilibrium. It should ensure safe long term encapsulation of hazardous wastes, including low and intermediate level radioactive wastes. Although the initial cost of highway construction using this method is somewhat higher than the conventional technique, if the cost of waste disposal is taken into consideration, the total expenditure, in most cases, should be actually lower than the combined cost of individual construction and disposal.
