The safety and economic aspects of heavy trucks and their relationships to pavement wear and damage continue to be one of the foremost areas of concern to transportation administrators. In their booklet "Roads and Vehicle Limits", the National Association of Australian State Roads Authorities (NAASRA) reviews the problems of truck overloading in Australia. They note that while allowable loads may be increased if more axles or tires are added to better distribute the load on the pavement, doublings the number of tire or axles does note necessarily mean that the load can be doubled. A truck loaded to the legal limit of 8.5 tons would caused the same damage as 5000 large cars. If it is overloaded to 10 tons, the pavement damage is doubled. Meanwhile, the first interim report hs been publish as part of a joint project being carried out by the Roads and Transportation Association of Canada (RTAC) and the Canadian Conserence of Motor Transport Administrators. It contains the results of a survey on the characteristics, of Canadian truck fleet equipment. Acqueintion of the data was needed since the study of trucks and trailers in service in canada involves computerized simulation of configurations.
