Abstract

Texture curing machine for the subsequent treatment of freshly produced concrete layers, in particular concrete pavements, of a specified width, comprising a machine frame supported by ground-engaging units, where working devices are attached at the machine frame in a stationary fashion or movable transverse to the working direction, and the working devices comprise texturing devices for applying a texture into the not yet hardened surface of the concrete layer and/or spraying devices for discharging a curing agent, said working devices acting on the concrete layer in longitudinal direction or in transverse direction to the working direction, it is provided for the following features to be achieved: that the working devices for applying either a texture or a curing agent comprise both a working device acting in longitudinal direction and stationary in operation and a working device movable to and fro across the width of the concrete layer, where each is alternately transferable from a resting position into an operating position in which the working devices do not collide with one another.
