What information is needed for an application?

Acceptable Documentation (see definition below) varies based on the application Case (see below for description of Cases). DOT&PF may require full suite of MASH tests or may deem it eligible for Federal aid based on Acceptable Documentation that determines that the modification does not affect the crashworthiness of the roadside safety hardware based on previous MASH crash testing and analysis. If necessary, crash testing may be required based on the engineering analysis. A device or hardware may be deemed eligible for Federal aid based on engineering judgment with Acceptable Documentation.

What are the application Cases?

DOT&PF classifies applications as belonging to one of five cases, and you must select one case for your application:

• Case 1. New Hardware has been MASH crash tested and has received an FHWA eligibility letter.
• Case 2. New Hardware has passed full suite or recommended critical testing matrix of MASH crash tests, but does not have an FHWA eligibility letter.
• Case 3. Hardware is significantly modified from what passed MASH tests; or, MASH crash tests were not conducted; or, MASH-compliance cannot be determined.
• Case 4. MASH tested hardware is modified (non-significant).
• Case 5. An NCHRP 350-compliant device for which a MASH-compliant replacement does not exist; or, a MASH-compliant device exists but does not meet the State’s needs; or, the device is a temporary work zone device manufactured on or before December 31, 2019 and still within its normal service life.

What is Acceptable Documentation?

Acceptable documentation may include:

• FHWA-issued eligibility letters pertaining to a specific system or system modification.
• Work products of ISO 17025 accredited crash test facilities using any of the following evaluation methods:
  • Documented successful crash testing concentrating on a full suite or critical test(s) for new hardware or modifications to existing hardware
  • Computer modeling and simulations
  • Other testing methods including dynamic tests
  • Engineering analysis including review of previous research
  • Compatibility with existing roadside hardware and Alaska specific performance requirements
• Reports from an accredited crash-test facility documenting performance of the specific system or modification under review.
• NCHRP report that covers the specific system or modification under review.
• Written engineering analysis performed by an accredited crash-test facility or by a professional qualified to make eligibility determinations.
