ｃｍの簡易舗装路を完成した。First, an enclosure was excavated, and the roadbed was formed by the following steps: subgrade compaction, laying a lower subbase using river sand, rolling the subbase, laying an upper subbase using crushed stone, and rolling the top subbase. Then A, I2
C! 233% by weight, 7% by weight of calcium acetate and Fe2
2.5 parts by weight of an aqueous suspension containing 0.05% by weight of O3 is kneaded with 100 parts by weight of Masato, 10 parts by weight of Portland cement and 7.5 parts by weight of water, and this is laid on the roadbed, After leveling 7, it is rolled with a roller and cured for a short period of 1 to 2 days to reduce the thickness of the surface layer to 5.
Completed a simple paved road of cm.
形成された簡易舗装路は、土の感触を保持した自然な美
しい仕上がりを有するものであり、歩行や自転車通行に
耐久し得る充分な強度を有し、かつ優れた透水性を有す
るものであった。The simple paved road that was created had a beautiful natural finish that retained the feel of earth, was strong enough to withstand walking and bicycle traffic, and had excellent water permeability. .
