KHIT 159: MASH Analysis of KYTC#s Standard Drawings

Grants and Contracts Details

Description

Abstract KHIT 159, MASH Analysis of KYTC’s Standard Drawings KYTC''s Standard Drawings encompass technical drawings and specifications that provide guidelines for the design and construction of highway-related infrastructure. Topics covered by these drawings include roadway design, roadside design, drainage, traffic control, and bridge design. The Division of Highway Design maintains oversight of KYTC’s Standard Drawings. The AASHTO Manual for Assessing Safety Hardware (MASH) contains guidelines for testing and evaluating roadside safety hardware in real-world crash scenarios, including crash cushions, guardrails, and barriers. A Joint Implementation Agreement approved by state departments of transportation, AASHTO, FHWA, and industry representatives gave deadlines by which new permanent installations and full replacements of safety hardware needed to comply with 2016 MASH criteria. Dates varied by type of safety hardware. For many devices, the deadline was on or before December 31, 2019. Over the past few years, KYTC has updated its Standard Drawings to ensure they meet the latest safety standards and guidelines, including those outlined in the 2016 MASH criteria. To facilitate this process, KYTC asked the Kentucky Transportation Center (KTC) to conduct MASH analyses of relevant Standard Drawings and identify areas where updates or revisions are needed to achieve compliance with MASH guidelines. The goal of this project is to ensure that roadside safety Standard Drawings are up to date and comply with the latest safety standards and guidelines so that KYTC delivers the safest and most effective transportation infrastructure possible for the people of Kentucky.
