Abstract
The aim of this research is to prepare a site & laboratory studying to define the distresses and the pavement condition for one of the main roads in Hilla city by defining pavement distresses and their arising causes by standard American Pavement Condition Index (PCI) method without any Pavement laboratory tests and compare Pavement condition definition with the familiar classical method after executing different tests which is required much efforts & cost, also the research is including how to repair the arising distresses with the recent technics which have to be employed during road pavement design or at distresses repairing to decrease or to prevent their arising. (50) road sectors were required for one of the Asphaltic road directions with(5.0)km length,(7.0)m width and listing their different pavement distresses by site inspection using (PCI) method to find the pavement condition index (PCI) values for each sector to define the pavement sectors condition. A selection of (10) asphaltic samples by core test and another(10) samples of road pavement from same locations to execute different tests. The (PCI) method values results showed that (30) sectors are in fair conditions, (20) sections are poor and the pavement include (8) distresses from a (19) standard distresses in this method which is supported by test results of classical method for Pavement condition definition and its distresses arising due to bad site execution of road pavement layers, inefficient wearing course to resist traffic loads and these distresses should be repaired by spraying emulsion fog seal, adding sandy seal layer with fine gravel some times and removing with repaving wearing course in some locations
