| 摘要： | This report on the Narrow Connecticut Impact Attenuation System (NCIAS) is another in a series of test reports that document NCHRP Report 350 compliance of various Connecticut-designed and-developed impact attenuation systems. The report summarizes the results of six full-scale crash tests performed on the NCIAS. All tests were conducted in accordance with the guidelines of NCHRP Report 350 for Test Level 3 devices. NCHRP Report 350 specifies eight tests for redirective, non-gating devices. Three of the eight tests were not conducted on the NCIAS because they are similar to three tests conducted under NCHRP Report 230 requirements, which the NCIAS passed. The five remaining tests were performed. One test was repeated after one of the cylinders was strengthened. The NCIAS passed all requirements for 4 out of the 5 test designations. It did not pass the requirements for the reverse hit test; therefore, it is required that the installation of the NCIAS not be at locations where it may be struck from the reverse direction. FHWA has approved the use of the NCIAS on the National Highway System at locations where reverse-direction impacts are unlikely. |
