Concrete rafts quickly spring to mind when considering the need to replace a pavement surface as fast as possible. This chapter examines the possibilities of such repairs. The development of repair systems has been driven by the need to achieve the rapid reinstatement of airfield pavements in war, after they have been cratered by aerial bombardment. The primary requirements of such repairs will be considered, followed by design considerations. The use of concrete rafts for rapid pavement repair has led to the development of specialist equipment which will be described in general terms. Also, details of practical experience will be reviewed. Finally, consideration will be given to the use of rafts for road pavement repairs plus possible future developments. |
