PURPOSE: A construction method of a yellow-earth road is provided to improve the visibility of pedestrians because a yellow-earth road contains red earth powder. CONSTITUTION: A construction method of a yellow-earth road is as follows. A mixture is prepared by mixing 30-35 weight% of yellow earth powder, 40-50 weight% of silica, 15-20 weight% of ceramic, and 5-10 weight% of red earth powder(S10). A kneaded mixture is produced by mixing the prepared mixture with 20-25 weight% of water(S20). The bottom of the mixture is polished and hardened(S30). The kneaded mixture is uniformly spread on the hardened surface of the mixture(S40). The top of the spread kneaded mixture is covered with vinyl for 2-3 days(S50). The covered vinyl is removed(S60). |
