In many developing countries road traffic is growing rapidly both in volume and in the size and weight of the vehicles using the roads. As a consequence highway engineers concerned with designing new roads or the strengthening of existing roads in developing countries require reliable information about the distribution of the axle loads of existing traffic, and when possible, information on national or regional axle load trends. The importance of reliable information on axle loads for pavement design purposes is emphasized by the now widely accepted assumption that the degree of pavement damage caused by an axle load is proportional to approximately the fourth or fifth power of the axle load. To provide adequate information on axle load distributions road-side surveys of axle loads are required. Such surveys can conveniently be made using portable wheel-weighing devices. This note describes a simple and convenient procedure for making axle load surveys in developing countries using portable weighing platforms. The procedure is based on experience gained by staff of the Overseas Unit who have undertaken a considerable number of axle load surveys in several developing countries.
