摘要： PURPOSE: A sandwich type athletic field construction method is provided to prevent cracking, lifting and the settlement of a base layer by maintaining proper elasticity, cushion, and various material properties necessary for an athletic track game. CONSTITUTION: A sandwich type athletic field construction method comprises a soil compaction step, a first rubble laying and compaction step, a second rubble laying and compaction step, a first pitch asphalt laying and compaction step, a second pitch asphalt laying and compaction step, a rubber chip and soft liquid urethane mixture laying step, a rubber chip and semi-rigid liquid urethane mixture laying step, and an emboss layer laying and line marking step. The second pitch asphalt laying and compaction step comprises a primer applying step. A rubber chip, a urethane chip, and two-liquid type soft polyurethane liquid are mixed for being applied after applying the primer.
