THE ALCONBURY HILL EXPERIMENT AND ITS RELATION TO FLEXIBLE PAVEMENT DESIGN

In a paper given to the First Conference on the Structural Design of Asphalt Pavements results obtained from the major full-scale pavement design experiment at Alconbury Hill during the first four years were given. The present paper summarizes the conclusions after 13 years. Although the major trends - such as the superior performance of dense bituminous base material and of rolled asphalt surfacings - have continued to be apparent, certain of the earlier tentative conclusions, and particularly those relating to the role of the sub-base, have needed revision. The traffic using the experimental road has been weighed by an electronic weighbridge and the number of cumulative 8200 kb (18,000 lb) axles has been calculated using the A.A.S.H.T.O. equivalence factors. This will allow a direct comparison to be made with the results of the A.A.S.H.T.O. Road Test for the forms of construction common to both experiments. A simple structural analysis based on elastic theory has been made for certain of the sections using lean concrete, wet-mix slag and rolled asphalt road bases. Although the broad conclusions are in agreement with the experimental findings the analysis illustrates some of the practical problems entailed in applying structural analysis techniques to the design of road pavements.
