连续侵入式微型圆锥贯入试验（CIMCPT）系统的开发，校准，并由路易斯安那州交通研究中心实施。锥贯入技术快速、可靠且具有成本效益，特别是与传统的现场表征方法（如钻孔、实验室和现场测试）相比。CIMCPT系统在路易斯安那州的道路设计和施工的实施阶段。CIMCPT被用于评估在Rayne附近I-10修复期间路面路肩支撑改道交通的结构能力，重新设计和建造富兰克林LA-182国道的石基层，以及评估塔卢拉附近I-20/密苏里州太平洋铁路立交桥路堤的破坏面。CIMCPT系统由路易斯安那州运输和发展部（LA DOTD）成功实施。与传统的地下勘探技术相比，在道路设计和施工中实施CIMCPT技术节省了LADOTD的资金和时间。
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 LADOTD money and time compared with traditional subsurface exploration techniques.
