Classification of construction problems in rigid highway pavements

Problems can be expected during construction of rigid pavements, since this process is sophisticated, and involves many activities like concrete placing, spreading, compacting, finishing, texturing, curing, protecting, jointing, testing, and other sub-activities. In addition, this process is performed over large areas, outdoors,and under miscellaneous conditions. Classification of these problems can be very helpful in control, minimize, and prevent them. This paper presents classification of construction problems in rigid highway pavements depending on their forms, appearances, locations, stages of occurrence, conditions, and any other common features among them. The problems, their description, probable causes, instantaneous solutions, preventive solutions are documented depending on written sources in the domain of rigid pavements construction.
