(80) in Hilla city which is two directions road of (9.85) km length, (8.0) m pavement width, (2.5) m shoulders and (5) m median width. The road consist of asphaltic concrete layer (10) cm thickness, sub base of (20) cm thickness and embankment about (1.0) m. The road pavement distresses that appeared despite its short age which is about five years raised inquiries. The road was divided to (98) stations with (100) m length for each direction. The site inspection was excuted and writing the road distresses according to Paver method then finding Pavement Condition Index (PCI) values for each sector. The (PCI) values of pavement showed that (120) sections are in fair conditions, (76) sections are poor and the pavement include (9) distresses from a (19) standard distresses due to bad site execution and design of roads layers, bad quality of asphaltic wearing course to resist traffic loads and to repair these distresses we need to spray emulsion asphalt layer, remove places of wearing course and to remove all road layers and to rebuilt in another locations | ||
