WATERPROOFING WORK ASPHALT COMPOSITION, WATERPROOFING HEATING TECHNIQUE USING THE SAME AND ITS HARDENED MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a waterproofing asphalt composition for meeting various kinds of requirements including fluidity in construction, break resistance in low-temperatures and long-time thermal creep resistance even when the melting temperature of the waterproofing work asphalt composition is reduced to 100°C or so, and to provide a waterproofing heating technique using the same and its hardened material.;SOLUTION: The waterproofing work asphalt composition consists of (1) asphalt: 40-90 wt% and (2) a material for imparting reactivity to the asphalt: 10-30 wt%. The composition has a melting viscosity of 30-2000cPs in a temperature range of 80-150°C and a softening point of 60°C or higher before hardened with reaction. The waterproofing heating technique using the same and its hardened material are provided.;COPYRIGHT: (C)2005,JPO&NCIPI
