• Abstract:
  This report presents the evaluation of the structural capacity of pavement shoulders to support diverted traffic during rehabilitation of I-10 near Rayne. The evaluation was conducted on a 12-mile segment of I-10, starting at the interstate of I-10 and state route LA-343 and ending at the intersection of I-10 and LA-111. This segment consists of a 6.2 mile segment consisting of 2-inch HMAC over soil cement base course and a 5.9 mile segment of 2-inch HMAC over a 6.0-inch deep stabilized sand/shell base course layer.
  
  Field and laboratory testing programs were conducted to determine the structural capacity of the existing shoulder during I-10 rehabilitation. The field testing program consisted of continuous intrusion miniature cone penetration tests (MCPT), nondestructive tests using the Dynamic Deflection Determination System (Dynaflect), and coring/undisturbed sampling of surface, sand/shell base, and subgrade soil. Laboratory tests consisted of determining physical properties of materials and unconfined compressive strength.
  
  The field tests were analyzed. The results, from both the miniature cone penetration test and the Dynaflect, confirmed that adding a 2-inch HMAC surface layer would improve the structural capacity of the shoulder to enable it to hold the diverted traffic during the I-10 rehabilitation.
