LABORATORY FACILITY FOR TESTING ROAD IRONWORK INSTALLATIONS

The term "road ironwork" is used to refer to covers that are placed over manholes, drainage gullies, water valves, and the like. Such ironwork can be found in virtually all highways, especially in urban areas. Highway engineers have to deal with a high incidence of premature failure in these installations, the total costs of which are estimated to be 207 million pounds sterling (U.S., $338 million, 1998) per year in the United Kingdom alone. These failures are generally characterized by gradual deterioration of the surrounding asphalt surfacing, associated with failure of the bedding material that supports the ironwork frame. The reasons for this high incidence of failure were investigated in a research project involving the construction of a full-scale laboratory test facility to simulate field conditions. This paper contains a description of the development of this apparatus. The results recorded from the apparatus were later used to identify the failure mechanisms that develop within road ironwork installations.
