REJUVENATION OF AFAILED ROAD PAVEMENT

The paper traces the history of a road pavement which showed signs of failure through cracking and loss of shape at a relatively early age. Despite continuing deterioration, extensive testing and experimenting finally led to the decision to rejuvenate the pavement by regulation and overlaying with bituminous concrete rather than to completely reconstruct. Deflection testing, using a Benkelman beam, was carried out on a number of occasions and subsequent deflections taken on the resheeted pavement suggest that the life of the pavement has been extended considerably. Conclusions include the importance of adequate initial compaction during construction, the value of the Benkelman beam as a research tool, the possibilities of pavement upgrading by means of overlays and finally, suggestions of topics for further useful research in this field.
