THE DESIGN OF NEW ROAD PAVEMENTS AND OF OVERLAYS: ESTIMATION OF COMMERCIAL TRAFFIC FLOWS

In order to determine the required thickness of a new road pavement, or of an overlay on an existing road, the total commercial traffic in the nearside lane has to be estimated for the desired life of the pavement. For an overlay, the total commercial traffic since the last major strengthening is also needed. In the present Report, the estimates of traffic flow made in Road Note 29 for the design of pavements have been brought up to date and extended. A nomogram has been prepared to facilitate the estimation process. The computations have also been used to prepare a second nomogram to assist in estimating the past traffic that has been carried by a pavement. /Author/
