Evaluation of Rutting Distresses on I-20 Near Minden, LA.
Noticeable rutting issues have been a problem for many years on a corridor of I-20, in both eastbound and westbound lanes, located near Minden, LA and near the Webster-Bienville parish line. At the request of the DOTD designers and District 04 engineers, the Louisiana Transportation Research Center (LTRC) asphalt research group performed a small scale forensic evaluation in December 2014. The request was made because a reconstruction project is planned and scheduled in an attempt to remediate the rutting issues observed. Evaluation of the site and asphalt cores retrieved showed considerable deterioration of the binder course due to its moisture susceptibility and due to inadequate moisture drainage. The support structure of the road was damaged and settling occurred on the surface layers causing severe rut issues. Based on these findings, full depth rehabilitation of the asphalt pavement is recommended. Additional breaking of the original JCRP pavement should be performed in various areas of the old test sections. In addition, it is recommend that the current underdrain system be removed and replaced.
