Field and Analytical Evaluation of the Effects of Tied PCC Shoulders and WidenedSlabs on Performance of JPCP

摘要

This study was conducted to evaluate the effects of widened slabs and tiedconcrete shoulders on the performance of portland cement concrete (PCC) pavements. As a part of this study, the Colorado Department of Transportation (CO DOT) constructed three test sections in the westbound driving lanes of I-70 during the summer of 1994. All three test sections are 11.25-in jointed plain concrete pavements (JPCP) with 15-ft joint spacing constructed on a 7-in asphalt concrete (AC) base which is the old pavement surface.
