D3527 Standard

D3527 is a widely recognized industry standard that specifies guidelines for the design and construction of barrier systems used in highway safety, particularly for roadside barriers like guardrails. It ensures these barriers effectively absorb impact energy and prevent vehicles from crossing into dangerous areas. The standard covers materials, testing methods, and performance criteria to ensure the barriers provide consistent and reliable protection. In essence, D3527 helps engineers select and install roadside barriers that improve safety for motorists by minimizing crash severity and preventing vehicles from leaving the roadway.
