| Abstract: | Reflection crack is a big problem for asphalt overlays on existing cement concrete pavement. Combined with experience of many corresponding projects and codes,reason of how reflection crack generates is analyzed,also different solutions under different conditions of existing cement concrete pavement are discussed in the paper. Finally,based on JTG D50—2006 Specifications for Design of Highway Asphalt Pavement,standard of classification for overlaying measures is introduced,and countermeasures are given about rubblizing disposal of the existing cement concrete pavement. |
