SLIP-FORM CONSTRUCTION OF HIGHWAY APPURTENANCES

This paper describes slip-form construction techniques for widening and resurfacing, curb and gutter building, single-lane concrete paving with integral curb, and concrete safety barrier. Formerly, most of this type of construction was done by using forms and hand tools. Labor requirements were high, and production rates were low. In recent years development of specialized slip-form equipment by contractors and equipment manufacturers has revolutionized this type of concrete construction. The authors describe some of the equipment available and the wide variety of equipment that provides for interchangeable mules or forms to shape concrete to almost any cross section. The paper presents some recommendations on suitable concrete mixes and finishing techniques for this type of work.
