The Application of Stepwise Regression in Analyzing Pavement Friction Data
The Maryland State Highway Administration (MDSHA) conducts periodical friction surveys on the pavement network to monitor its overall skid resistance condition. It was found from the survey data that pavement friction could be affected by numerous variables: rehabilitation activities, traffic patterns, traffic volumes, survey vehicle test speeds, weather-related factors, and etc. Those variable…
Resilient Modulus Characteristics of Varying Percent of Reclaimed Asphalt Pav…
Utilization of reclaimed asphalt pavement (RAP) aggregate in highway projects has become common practice in the United States because it has considerable environmental and economical advantages. This study evaluates the resilient modulus (Mr) of a crushed RAP on its own, a basaltic virgin aggregate (VA) on its own as well as when the two are bended for use in pavement base and subbase courses. …
Reflective and thermal cracking modeling of asphalt concrete overlays
Although asphalt concrete overlay systems represent a rapid and economical alternative for the repair of deteriorated pavements, reflective cracking continues to be major cause of premature deterioration of these systems. A better understanding of the complex mechanisms behind reflective cracking in asphalt overlays must first be obtained before significant advances in reflective crack prev…
Rut depth measurement method and analysis at the FAA's National Airport Pavem…
The FAA developed and modified a truss profiler, which is independent of pavement profiles, that is used to monitor rutting of flexible pavements at the National Airport PavementTest Facility (NAPTF). The truss profilerwas developed to replace the more labor-intensive and time-consuming straightedge measurements. Transverse profiles corresponding to the cumulative number of load repetitions app…
