Document Type and Number:
WIPO Patent Application WO/2005/108677
Kind Code:
A1
Abstract:
The invention relates to a device for the pre-cracking in the fresh state and the filling of cracks in cement road bases. The inventive device is used to produce mechanically and/or automatically the transverse cracks that are normally provided in road bases or surfaces which are treated with cement and which are intended to serve as a base for the corresponding asphalt layer in the construction of roadways. In addition, the device is also used to fill the aforementioned cracks using a bituminous product in order to eliminate or reduce crack reflection in said compacted surfaces. According to the invention, the device consists of: a vertical blade (1) comprising outlet holes (3) for the bituminous product (4); and a horizontal plate (5) which is solidly connected to the upper edge of the blade (1), the front edge of said plate being arched upwards (6), such as to define a runner which slides along the surface penetrated by the blade (1), thereby forming a crack which is simultaneously filled with the bituminous product (4) which is projected through the outlet holes (3) in the rear edge of the blade. The runner/blade assembly is solidly connected to a frame so that it can be hitched to a towing vehicle (21) such as a small tractor, a quad or similar.
