PROBLEM TO BE SOLVED: To provide a method for injecting a hardener to a joint part of a drainage pavement, while a conventional spraying method in which the hardener having a relatively low viscosity is sprayed from a surface of the drainage pavement so as to sink into a lower part of a drainage layer and to be solidified to form a water shielding layer through easy construction with reduced scattering of aggregate in the drainage layer for durability improvement has no problem in application to a uniform pavement part, but causes lack of the hardener at the joint part.SOLUTION: A method for injecting a hardener to a joint part of a drainage pavement includes simultaneous injection from a plurality of moving nozzles spaced at a predetermined interval in a traveling direction of the nozzles. Two nozzles are installed on each locomotive vehicle, and a plurality of the locomotive vehicles are used, so that the nozzles are prepared. The hardener to be injected has a viscosity of 200 mPa s or less. The hardener hardens into a solidified object which has a penetration of 150 or less. |
