Pavement Method: Water-Resistant Drainage Pavement Method (POSMAC Method)
Waterproof drainage pavement (POSMAC) is a technology for constructing drainage pavements. 【Features】 ○ Using an asphalt finisher equipped with an emulsion spraying device (SPAF), high-concentration modified asphalt emulsion (cationic GS-C) is sprayed in large quantities and uniformly while simultaneously laying the drainage mixture, forming a waterproof layer beneath the drainage mixture layer to protect the base surface from infiltrating rainwater and other sources. ○ By utilizing this method, the reliability of the pavement is enhanced by protecting the base surface compared to conventional drainage pavements that are constructed in a single layer. ○ It allows for significant cost reduction compared to drainage pavements constructed in two layers, including the base layer. ○ The filling of asphalt contributes to stress relief effects, which is expected to suppress reflection cracking. ● For other functions and details, please download the catalog.
