<P>PROBLEM TO BE SOLVED: To provide a water-preventive pavement which maintains high water retentivity for an extended period while having a practically efficient compression strength, and a method of manufacturing the water-preventive pavement. <P>SOLUTION: A water-retentive pavement 10 has a porous water-retention layer 16, which comprises polybutadiene-based organic binder material 18 and aggregate 20. Content of the polybutadiene-based organic binder material is preferably between 0.5 to 8.0 pts.mass inclusive to 100 pts.mass of the aforesaid aggregate, while viscosity of the organic binder material at the temperature of 23°C - BH type viscometer with No. 7 rotor at 10 turns - is preferred to be 100,000 mPa s or less. <P>COPYRIGHT: (C)2012,JPO&INPIT |
