The relationship established between the deflection of road pavements and their long term performance under traffic provide the engineer with a relatively simple means of forecasting the future performance of existing roads and designing measures for their structural strengthening. This report provides information on the recommended methods of operating the Deflection Beam and Deflectograph, the two types of measuring equipment in use in the United Kingdom. It also draws attention to the possible consequences of using non-standard techniques of operation. The first part of the report describes preferred operating procedures when the equipment is used to carry out a deflection survey along a length of road and indicates the way in which these procedures are a consequence of the design of the machine and the conditions on the road. The second part describes procedures for ensuring that the Deflectograph is functioning effectively when carrying out a deflection survey. (Copyright (c) Crown Copyright 1978.)
