JOINTED CONCRETE PAVEMENT REINFORCED WITH WELDED WIRE FABRIC

The current state of the art in the design of jointed pavements is presented. Many aspects of both design and maintenance are discussed and special emphasis is given to joint design. Pavement fundamentals are summarized, basic pavement components are briefly reviewed, pavement types, suitability and relative costs are discussed, and factors (calculation of traffic capacity, indicators of soil support, disturbed soils and recompaction bases and subbases) affecting pavement design are detailed. Slab curling stresses are induced by temperature differentials, friction stresses by changes in average slab temperature, and load stresses by axle loads. From tests and theory, load stresses in modern pavements with good load transfer are greater for wheels at slab edges some distances from the joint. Pavement thickness design is discussed, steps for the design calculations are listed, and aspects such as truck loads and frequency, materials, factor of safety, modification thickness, and a computer solution of a sample problem are detailed. Factors which affect the choice of slab length are covered. Designation, specifications, allowable stresses and standard practices relating to welded wire fabric are set forth. Fabric for pavement with skewed joints, tie bars and handling and placing fabric are also discussed. Consideration is given to pavement joints, airfield pavements, residential streets and parking areas. Notes on pavement maintenance (foundation problems, joint problems and construction traffic) are also provided.
