| 摘要： | Over the course of this project, a low-profile longitudinal barrier was developed and tested in accordance with the National Cooperative Highway Research Program (NCHRP) Report 350. The low-profile barrier consists of a 40 inch by 12 inch footing with a 6 inch curb and rectangular rail. The overall height of the barrier is 18 inches. The dimension of the rail is 8 inches by 3 inches with a thickness of 3/8 of an inch. The barrier tested was approximately 100 feet long with a total of 9 posts installed at 10 feet on-center. The barrier was constructed at the Caltrans Dynamic Test Facility in West Sacramento, California. . Two full-scale crash tests were conducted under the NCHRP Report 350 Test Level 2. The first test, test 2-11 was conducted with a pickup truck. The second test, test 2-10 was conducted with a small car. Both tests met the NCHRP Report 350 evaluation criteria for TL-2 longitudinal barriers. The results of both tests were within the limits of Report 350 guidelines. The low-profile barrier tested in this project is recommended for approval on California highways in areas designated as Test Level 2. |
