ABSTRACT

There are a number of different types of concrete pavements that have been built. However, for the most part, they have two features in common. First, they resist traffic loads through flexure of the concrete. If reinforcement is used, it is used for crack control and not to carry load. The second element is that concrete pavements contract due to drying shrinkage of the concrete, and expand and contract due to thermal effects, and these movements must be dealt with. Different types of pavements use joints, reinforcing steel, or both. The term “conventional concrete pavements” is generally taken to mean

either jointed plain, jointed reinforced, or continuously reinforced concrete pavements (the first three categories described below) but not other types. Design and detailing of joints is important for these pavements. All three conventional pavement types have been used as overlays, although jointed plain overlays are most common. Prestressed and precast concrete pavements are used for similar applica-

tions as conventional concrete pavements, but have been used infrequently. Other types of concrete pavement include roller compacted concrete (RCC) and pervious or porous concrete, which are generally used for specialized industrial or parking lot applications.
