Pavement Manual: Paving Operations

Two types of paving operations are used for the construction of rigid pavement. One is fixed-form paving, and the other is slip-form paving. Both methods have some common operations as further delineated here. First, both methods require accurate survey controls that are used to establish the proper alignment and grade of the concrete pavement.
