ABSTRACT:
A rumble strip rolling device for attachment to a conventional asphalt roller. The rumble strip rolling device includes a support member for attachment to the asphalt roller, a pivot member having one end thereof pivotally secured to the support member for movement between a first position and a second position, a slide member slidably mounted on the pivot member for movement between a third position and a fourth position, a first hydraulic cylinder for adjusting the pivot member between the first position and the second position, a second hydraulic cylinder for adjusting the slide member between the third position and the fourth position, a roller drum assembly having a roller drum frame and a roller drum rotatably supported on a shaft that is supported by the roller drum frame, and a connector for pivotally connecting the roller drum frame to the slide member. The shaft has a first axis substantially perpendicular to a direction of movement of the asphalt roller and the roller drum frame is pivotal about a second axis substantially parallel to the direction of movement of the asphalt roller. Pivotal movement of the roller drum frame about the second axis allows the shaft and the roller drum thereon to remain substantially parallel to a surface being rolled during rolling operations. The first and second hydraulic cylinders enable the vertical and lateral position of the roller drum assembly to be selectively adjusted during use and non-use of the roller drum.
