ROADBED IMPROVING MATERIAL FORMED OF MIXTURE OF PULVERIZED REFUSE MOLTEN SLAG AND SLAKED LIME

摘要

PROBLEM TO BE SOLVED: To provide a roadbed improving material capable of providing practically sufficient compression strength, formed of a mixture of refuse molten slag obtained by pulverizing molten materials discharged from city waste melting facilities into a particle size of≥425μm with slaked lime of≥5 wt.% addition rate. SOLUTION: The roadbed improving material of the invention formed of a mixture of pulverized refuse molten slag and slaked lime is obtained by quenching molten materials discharged from city waste melting facilities to coagulate them, pulverizing the refuse molten slag so as to have a particle size within a range of 425-10μm and then adding thereto 5-15 wt.% slaked lime. In particular, the road improving material of the invention formed of a mixture of pulverized refuse molten slag and slaked lime is obtained by quenching molten materials discharged from city waste melting facilities to coagulate them, pulverizing the refuse molten slag so as to have a particle size of 250μm and then adding thereto 10 wt.% slaked lime.
