摘要：	A continuous-intrusion miniature cone penetration test (CIMCPT) system was developed, calibrated, and implemented by the Louisiana Transportation Research Center. The cone-penetration technology is fast, reliable, and cost-effective, especially when compared with the traditional site-characterization methods such as borings and laboratory and field tests. The implementation phase of the CIMCPT system in roadway design and construction in Louisiana is presented. The CIMCPT was used to evaluate the structural capacity of pavement shoulders to support diverted traffic during the I-10 rehabilitation near Rayne, to redesign and construct a stone base-course layer for State Route LA-182 in Franklin, and to evaluate the failure surface of the I-20/Missouri Pacific Railroad overpass embankment near Tallulah. The CIMCPT system was successfully implemented by the Louisiana Department of Transportation and Development (LA DOTD). Implementation of the CIMCPT technology in roadway design and construction has saved LA DOTD money and time compared with traditional subsurface exploration techniques.
