<p>PURPOSE: To waterproof or moisture proof a water permeable structural material by applying a soft sheet-like waterproofing laminate molded beforehand to the structural body at temperatures under a prescribed temperature. CONSTITUTION: Process oil whose white clay gel separation range is saturated compound 10-30%, polar compound 10-20%, aromatic compound 50-85%, and asphaltene 5-20% is heated by a mantle heater. Secondly, thermoplastic block polymer powder of styrene and butadiene is mixed by a vane-type agitator and then the rubber mixture is mixed with the process oil. Asphalt whose alumina separation range is saturated compound 5-20%, naphthene-based aromatic compound 30-50%, and asphaltene 5-20% is added thereto. Rubber-like asphalt is poured on a released paper and coated with polyethylene film.</p> |
