Disclosed is an anti-slab height control system and related method for regulating the elevational position of an anti-slab mounted to a cold planer configured for milling a roadway. The cold planer includes a milling drum. The system comprises an anti-slab, a position sensor, a controller and an actuator. The controller is configured to determine an actuator adjustment based on a predetermined height, position data and a cutting depth of the milling drum. The position data is indicative of a current elevational position of the anti-slab. The actuator is configured to move the anti-slab based on the actuator adjustment from the current elevational position to a first elevational position, wherein the bottom side of the anti-slab is disposed at the predetermined height above the roadway when the anti-slab is in the first elevational position.

Methods, compositions and systems for prolonging the lives of transportation surfaces, including pavement, runways, bridges and parking structures include physically altering the transportation surface and chemically protecting the transportation surfaces. Physical alteration of a transportation surface may include physically altering one or both of a microtexture and a macrotexture of the transportation surface. Chemical protection of a transportation surface may include hardening and/or densifying the transportation surface. The transportation surface may be chemically protected while physically altering the transportation surface or after the transportation surface has been physically altered.

In a texture curing machine for the subsequent treatment of freshly produced concrete layers of a predetermined width, in particular concrete roadways extending longitudinally in the direction of travel, comprising a machine frame supported by ground-engaging units, with no less than one texturing device movable transverse to the working direction for applying a texture, by means of multiple texturing tools, into the not yet hardened surface of the concrete layer, and with a controller unit for adjusting the travelling speed in the direction of travel, it is provided for the following features to be achieved: the controller unit captures the travelling speed and/or the traversing speed of the texturing device and, during forward or reverse travel, controls the travelling speed and/or the traversing speed of the texturing device in transverse direction in accordance with a specified texturing angle, with the texturing angle ensuing from the relation of the speeds.
