NCHRP IDEA 20-30/IDEA 219 [Active (IDEA)]

A Novel Durable, Healable and Conveniently Removable Pavement Marking Material Suitable for Both Permanent and Temporary Marking Uses

  Project Data
Funds: $129,999
Staff Responsibility: Inam Jawed
Research Agency: North Dakota State University
Principal Investigator: Long Jiang
Fiscal Year: 2019

This project will develop and test an epoxy vitrimer-based new pavement marking material that would be durable and self-repairable as well as, when needed, easily removable from the pavement without using any forceful or harsh measures.  Work in Stage 1 of the project will focus on the synthesis and characterization of the vitrimer epoxy and initial pavement marking material formulations. A series of vitrimer epoxy samples will be synthesized under different conditions and their properties (such as mechanical, rheological and thermal properties, etc.) systematically evaluated. Based on the results, the synthesis conditions will be optimized for pavement marking use.  The optimized vitrimer epoxy will be mixed with other ingredients (pigments, fillers, etc.) at different ratios and conditions to produce a series of pavement marking products and their performance evaluated under laboratory conditions. Formulations with desirable properties will be identified. Stage 2 work will focus on field testing, cost and market analysis, product knowledge dissemination and implementation. The potential products identified from Stage 1 investigation, will be first field tested on the North Dakota State University’s ground. Based on test results, selected products will be further tested at MnROAD I-94 testing facility. Life-cycle cost analysis will be performed based on the final product formulations. Market information will be gathered from internet, DOT personnel and industrial partners, and a life-cycle analysis will be performed on the collected data. Knowledge of the new product will be disseminated through face-to-face interactions, meetings, Upper Great Plains Transportation Institute platforms, social media, publications and webinars. The new marking material will be installed in a real project on the NDSU campus.. The final report will provide all relevant processes, data, findings, and conclusions along with the procedures for marking installation and removal.
