This article describes the construction of a mass concrete pavement, carried out with the aid of a Gunter-Zimmermann sliding formwork, manufactured in the United States. This device guides itself automatically by means of an electronic control, and does the following set of operations simultaneously: it spreads the concrete over the whole width of the pavement (7.5 ms); vibrates it; shapes it and gives it the final thickness with the aid of the sliding formwork; it provides a longitudinal cut, which serves as a dilation joint; fills this joint with plastic material; places connecting reinforcements across the joint, half way down the depth of the pavement; and smoothes out the final surface. The author refers to the final surface finish; discusses the sawing of the transversal joints, various tests and checks, and the possibilities and limitations of this constructional procedure. He finishes by enumerating some general inferences on this method of road construction.
