WATERPROOF ASPHALT CONCRETE COMPOSITION FOR PRIME COATING FOR IMPROVING WATERPROOF PERFORMANCE BY INCLUDING RECYCLED AGGREGATE OF RECYCLED ASPHALT, SIS, SBS, AND FINE AGGREGATE POWDER WITH IMPROVED GRAIN SIZE, AND CONSTRUCTION METHOD FOR SAME

摘要

The present invention provides a waterproof asphalt concrete composition for prime coating, which improves waterproof performance, and a construction method for the same. According to the present invention, the waterproof asphalt concrete composition for prime coating includes: 100 parts by weight of recycled aspha 250-1,000 parts by weight of recycled aggregate of recycled aspha 0.1-50 parts by weight of styrene isoprene styrene (SIS); 0.1-50 parts by weight of styrene butadiene styrene (SBS); 0.1-50 parts by weight of a petroleum resin; 1-10 parts by weight of a performance enhancer; 250-1,000 parts by weight of new aggregate; 30-150 parts by weight of the fine aggregate powder; and 0.001-1 parts by weight of charcoal powder. According to the present invention, the waterproof asphalt concrete composition for prime coating, which improves the waterproof performance by including recycled aggregate of recycled asphalt, the SIS, SBS, and fine aggregate powder with an improved grain size, can be uniformly and quantitatively constructed and then rapidly and conveniently paved while maintaining strong adhesion between the steel surface, concrete layer, and asphalt. Moreover, the waterproof asphalt concrete composition has excellent waterproof performance and good durability and prevents plastic deformation, aging, and/or stripping from easily occurring. The waterproof asphalt concrete composition is a PG 82-34 grade and prevents water from permeating and pot holes from being formed. The waterproof asphalt concrete composition can be paved at low cost and can be applied to a steel bridge or concrete slab.;COPYRIGHT KIPO 2019
