Plant mixing type modified asphalt composition with excellent sound proofing and draining property and method of paving established road by thereof

摘要

The invention low noise for plant mix- relates to a drainage modified asphalt compositions and the existing road pojangbeop using the same modified asphalt composition of the present invention (i) with respect to the asphalt 100 parts by weight of (ⅱ) cellulose fiber 4-8 parts by weight of the ( ⅲ) a linear styrene-butadiene-styrene rubber 100 parts by weight compared to polyamide-based polymer 20 - 40 parts by weight of high boiling point aromatic hydrocarbon compounds 20 to 40 parts by weight of mixed composition of an organic polymer compatibilizer of 30 to 60 parts by weight and a modifying agent having characterized in that 8-12 parts by weight of mixture. ; Existing road pojangbeop according to the invention form the modified asphalt lateral raceway (A) on the existing road composition and before packing the modified asphalt mixture was mixed with an aggregate and a longitudinal raceway (B) on the existing road, and the species and the raceway direction (B) and a multiple transverse connecting the drainage tank positioned in the gutter (C) characterized by forming a dry-cutting process. ; Asphalt composition, modification, plant mix, the existing road, pojangbeop, quiet castle drainage.
