PURPOSE: A construction method of expandable joint with a drain facility is provided to rapidly guide water from an expandable joint part to a drain, enhance drain performance, and more rapidly discharge water from an elastic concrete layer and an upper layer. CONSTITUTION: A construction method of expandable joint with a drain facility is as follows. A foundation layer and an upper layer are cut to form a space to hold an expandable joint member(S1). An upper layer is cut to form a space to hold a drain sheet(S2). The drain sheet is installed on a part where the foundation layer has been cut. The drain sheet is installed to be concave to correspond to the expansion of road(S3). An elastic concrete layer is formed on the upper layer(S4). The expandable joint member is installed(S5). |
