A texturing machine is provided for the subsequent treatment of a freshly produced concrete layer. Left and right height sensors are arranged to detect a height above the freshly produced concrete adjacent the left and right edges of the layer. At least one crown height sensor is arranged to detect a height above a crown of the freshly produced concrete layer. A controller is configured to receive input signals from the height sensors and to communicate height control sensors to the height adjustable columns and to communicate a crown control system to the crown actuator. A direction sensor may also detect at least one of the edges of the freshly produced concrete layer. The controller may communicate a direction control signal to a steering actuator of one of the ground engaging units of the machine.

A method for installing hot asphalt pavement includes heating an aggregate to a temperature of from about 350 F. to about 400 F. using an emitter comprising a birefringent material, the emitter generating electromagnetic radiation having a wavelength of from 2 microns to 1 millimeter, wherein the aggregate is a recycled asphalt pavement; adding the aggregate to an asphalt in a mill to yield a mixture of aggregate with baked-on asphalt; laying the mixture down over a base to form a first layer of lift; and compacting the first layer.

The invention comprises a method of forming a slab on grade. The method comprises placing a first layer of insulating material horizontally on the ground and placing plastic concrete for a slab on grade on the first layer of insulating material. The plastic concrete is then formed into a desired shape having a top and sides. A second layer of insulating material is placed on the top of the plastic concrete and the first and second layers of insulating material are left in place until the concrete is at least partially cured. The second layer of insulating material is then removed. The product made by the method is also disclosed. A slab on grade is also disclosed.

The grounded modular heated cover is disclosed with a first pliable outer layer and a second pliable outer layer, wherein the outer layers provide durable protection, an electrical heating element between the first and the second outer layers, the electrical heating element configured to convert electrical energy to heat energy, a heat spreading layer, and a thermal insulation layer positioned above the active electrical heating element. Beneficially, such a device provides radiant heat, weather isolation, temperature insulation, and solar heat absorption efficiently and cost effectively. The modular heated cover quickly and efficiently removes ice, snow, and frost from surfaces, and penetrates soil and other material to thaw the material to a suitable depth. A plurality of modular heated covers can be connected on a single 120 Volt circuit protected by a 20 Amp breaker. The modular heated covers are grounded for safety using the conductive heat spreading layer.
