Pavement Roughness Measurement Using Android Smartphones: Case Study of Missouri Roads and Airports

Keeping airport pavement in good condition requires accurate and timely data on existing pavement conditions. Since many existing pavement survey methods can be costly and labor intensive, there is a need for simple and low cost tools to facilitate the evaluation of airport pavement condition for smaller airports with limited resources. To address this need, a study was undertaken to evaluate an android smartphone application for use in assessing airport pavement condition. To perform this evaluation, an initial validation study was performed on two sections of I-70 in central Missouri. The smartphone application was utilized to collect International Roughness Index (IRI) data for all 27 of the state funded general aviation airports in Missouri. The data were then analyzed and compared with the construction and maintenance records for the airports. The study found that the smartphone application (app) has the potential to be an effective low cost tool for assessing airport pavement condition. The smartphone estimated IRI values were close to those measured by Missouri Department of Transportation's (MoDOT’s) Automatic Road Analyzer (ARAN). The measured IRI data classified most of the test sections in agreement with MAP-21 requirements. The obtained trends agreed well with the construction and maintenance records of the airports. An equation was developed to predict Pavement Condition Index (PCI) based on the IRI values measured from the smartphone application. Future enhancements to the research could include the use of more vehicles and smartphones and the use of aircraft cab acceleration data. An improved graphical-user interface (GUI) should be developed for transfer of the app to airport managers.
