Texas IRI Summary (2000-2005)
The paper reports results of a statistical analysis done to evaluate International Roughness Index (IRI) on Texas roads from 2000 to 2005. The objective of the analysis was to identify research focus areas to assist TxDOT in improving the overall riding quality of the Texas road network. Analyses were done on Asphalt Concrete Pavement (ACP), Continuously Reinforced Concrete Pavement (CRCP) and Jointed Concrete Pavement (JCP) roads. IRI results from Interstate Highways (IH), United States (US) Highways, State Highways and Farm to Market (FM) roads with and without surface treatments are reported. The analyses indicate that the mean IRI data as measured in the left and right wheelpaths of roads using automated inertial profilers are log-normally distributed. IRI as measured in the right wheelpath is consistently higher than that measured in the left, in particular for FM roads with surface treatments. ACP generally have the lowest IRI values (highest ride quality) followed by CRCP and then JCP. Findings suggest that significant improvements in the overall ride quality of the Texas roadway network can be achieved by focusing research efforts on FM roads with surface treatments. The use of fine thin HMA to overlay old surface treatments as well as paving of shoulders on FM roads is recommended.
