While improving water resistance, it has flowability equal to or greater than that of coarse-grained asphalt concrete!
"K-MAS Base (Type: H)" is a mixture developed for the base layer of permeable pavement, based on a macadam structure with high water resistance and flow resistance. Since it is a macadam structure based on gap grading, it exhibits high flow resistance without significantly changing the materials used. Additionally, it demonstrates high water resistance due to the ability to set the void ratio between 1% and 4%. (Coarse graded asphalt concrete has a void ratio of 3% to 8%.) 【Features】 ■ The basic performance is achieved through the use of store asphalt, resulting in higher cost performance compared to existing coarse graded asphalt concrete. ■ Depending on the construction site, it is possible to use modified Type I asphalt, modified Type II asphalt, recycling materials, etc. ■ It can accommodate various traffic conditions. *For more details, please download the PDF or feel free to contact us.

basic information
【Overview】 ■ The maximum particle size of the aggregate is set to the top particle size of 20mm or more, and by minimizing the coarse aggregate in the range of 13 to 5mm as much as possible, we create a gap particle size within the coarse aggregate. * For more details, please download the PDF or feel free to contact us.
