Abstract:A study was conducted to assess the effectiveness of the International Roughness Index (IRI) and Heavy Articulated Truck Index (HATI) to identify pavement sections subject to high dynamic wheel loads (DWL). HATI is a profile-based roughness index used by some Australian road agencies to identify road sections providing poor ride quality for heavy trucks. The longitudinal surface profile data of ten pavement sections were used to simulate DWL caused by a typical fully laden articulated truck and to calculate re… Show more
