NETIS Registration Number: SK-140004-VE (High Blown Method)
"High-Brown SA" is a heat-welded modified asphalt emulsion for waterproofing construction, made from highly rigid modified asphalt. By applying it in large quantities (over 0.8 liters/m²) using a dedicated distributor on the base layer, a thick tack coat film is formed. When a porous mixture is laid on the surface, the asphalt film fills the voids beneath the porous mixture through heat welding, creating a waterproof layer that protects the base layer. After decomposition, it adheres poorly to tires, making it less likely for the tack coat to be disturbed even if construction vehicles enter, ensuring waterproofing while promoting the integration of the layered structure and preventing dirt on surrounding roads. 【Features】 ○ NETIS registration number: SK-140004-VE ○ By applying over 0.8 liters/m², it can achieve high waterproofing functionality → The permeability coefficient becomes 10⁻¹ to 10⁻² cm/s smaller compared to when not applied ○ By laying a heated mixture on the surface, it exhibits strong adhesion due to heat welding → It suppresses slipping between materials and inhibits aggregate dispersion ○ It fills cracks in existing pavement surfaces and suppresses reflection cracks For more details, please contact us or download the catalog.

Company information
Showa Asphalt Industry Co., Ltd. is a company engaged in various asphalt-related businesses, including asphalt emulsions, modified asphalt, asphalt mixtures, and straight asphalt. Showa Asphalt Industry takes the concerns of our customers, the local community, and our employees seriously, striving to become a unique company that brings joy to our customers by utilizing our unique technological capabilities to propose and improve solutions. We aim for business development and social contribution. For example, after opening our Okinawa branch in 1972, we found that customers in the Sakishima Islands were performing a very dangerous task of opening the top of each drum of asphalt to dissolve the asphalt liquid for use. In response to customer requests for improvement, we developed the 10-ton container asphalt distribution system. This system significantly contributed to safety and improved work efficiency by eliminating direct contact between workers and high-temperature asphalt. Showa Asphalt Industry Co., Ltd. values the voices of our customers and will actively challenge ourselves to do what only SHOREKI can do.
