PURPOSE: A permeable elastic floor structure without a surface drainageway and the construction method are provided to make quick drainage possible without installing a separate drainage facility, to reduce the cost of construction and to shorten a period of construction. CONSTITUTION: A permeable elastic floor structure without a surface drainageway comprises a mat(20) spread on the road(1) to reinforce the bearing capacity of the ground, a permeable layer(30) spread on the top of the mat to the appointed thickness and composed of rubble aggregate and a binder to drain off water transferred from the upper part rapidly, a binder layer(40) coated on the top of the permeable layer to the appointed thickness to increase the impact resistance of the permeable layer, a shock absorbing elastic layer(50) spread on the top of the binder layer to the appointed thickness and composed of rubber chips and a binder to have high elasticity, and a drain device(60) installed to the permeable layer and equipped with a perforated pipe(62) to drain off the water drained to the permeable layer to a collecting well. |
