The paper reviews the role of highway functional classification in pavement management. Predominantly, technical classification is used in pavement management in CIS countries. The paper raises importance of highway functional classification in pavement maintenance in order to efficiently manage road network. IRI roughness index is widely used to monitor, assess road condition, analyze life cycle

The role of highway functional classification play an important role in road asset management. While in planning stage many factors are uncertain, and based on prediction assumption that traffic volume increases due to new business opportunities in the area. In analyzing existing roads transportation planners and engineers have to pay attention to how heavily road is used by different type of vehicle and their purpose. Technical classification doesn't answers key questions such as how a road section is used by road users, what is the purpose. Contrarily, highway functional classification approach let to study two main transportation functions such as mobility and access. Two primary transportation functions of roadways, namely mobility and access, and describes where different categories of roadways fall within a continuum of mobility access. In addition to mobility and access, other factors that can help determine the proper category to which a particular roadway belongs-such as trip length, speed limit , volume, and vehicle mix. The concept of functional classification defines the role that a particular roadway segment plays in serving this flow of traffic through the network. Roadways are assigned to one of several possible functional classifications within a hierarchy according to the character of travel service each roadway provides. Planners and engineers use this hierarchy of roadways to properly channel transportation movements through a highway network efficiently and cost effectively [1].
