USE OF CONTINUOUSLY REINFORCED CONCRETE OVERLAYS, A2

The Boughton and Harbledown bypasses forming part of A2 in Kent, have, since their completion in 1976, carried traffic loading for which they were then designed. A maintenance contract was awarded to Arc Construction in June 1981, to give the carriageways a further 20 years designed life. This required laying bituminous overlays up to 300 mm thick. However, with the agreement of the Department of Transport four experimental 1 km lengths of continuously reinforced concrete overlay 200 mm thick, were included in the contract; the first time that this technique had been used over an existing flexible pavement in the UK. This paper describes the history of the road, the subsequent overlay design and the method of construction of the overlay whilst maintaining traffic flows on A2. (Author/TRRL)
