... 129   BCOAs have been successfully used to rehabilitate rutted and shoved but otherwise structurally sound asphalt pavements. BCOAs are relatively easy to construct compared with other overlay methods, require only simple preoverlay preparation of the existing asphalt pavement, expedite construction through placement of thinner concrete layers directly on existing pavement, and provide a cost-competitive rehabilitation alternative.

... 130 Evaluation of Bonded Concrete Overlays on Asphalt Pavements and slab sizes were 6-in. thick 6- × 6-ft slabs, 4-in.

... Conclusions and Further Research 131   difference exists between automated distress and visual distress collection methods for the projects evaluated. Faulting measurements were 93% different, corner breaks were 33% different, transverse cracking was 20% different, and total cracking was 26% different.

... 132 Evaluation of Bonded Concrete Overlays on Asphalt Pavements However, estimated bond condition and actual core condition were confirmed on only 41% of the cores, as the coring operation may have caused debonding of some cores. Cores extracted from each good and poor segment were used to determine layer thickness and bond condition.

... Conclusions and Further Research 133   evaluates joint spacing ranging from 5- × 5-ft to 8- × 8-ft and BCOA layer thicknesses from 4- to 8-in. Results of the sensitivity analysis indicated that design methods are sensitive to changes in asphalt layer thickness (except BCOA-ME)
