Guide for Construction of Concrete Pavements and Concrete Bases
|Publication Date:||1 July 1991|
Rapidly changing equipment and conditions under which concrete pavements and bases are constructed dictate the use of more general terms than are ideal in a report of this kind. This report is intended as a guide to preparation or selection of specifications which will assure good results under normal conditions, using established and proven practices. However, there have, in recent times, been many changes in the equipment and methods used to construct concrete pavements and bases. The use of improved equipment is to be encouraged so long as the basic requirements of sound construction are observed, and provided the quality of the finished product is comparable. Regardless of the type of equipment used, good construction depends in large measure on the skill of crews involved in the construction process.
In particular, it should be recognized that the slipform method of construction is capable of producing pavement of a quality equal to that produced by equipment operating on side forms and at substantially lower costs. Accordingly, the slipform method is often the preferred system. Fig. 1 illustrates the slipform method of laying concrete pavements (or bases).
