Project Description: 

In the previous study, the research team collaborated with the City of Battle Ground in Washington and constructed a test road incorporating plastics amendments in 2024, using the dry method. The objectives of this study are to:

1. Evaluate the field performance of plastic-amended asphalt and compare it to conventional asphalt sections.
2. Assess the impact of plastics in asphalt on skid resistance of vehicles.

Outputs:

The study provides comprehensive data on the structural and functional performance of plastics-modified asphalt, including durability, cracking, and rutting resistance.  Microplastics generation is quantified through wear and weathering studies, while a life cycle analysis evaluates costs and impacts. These outputs help develop guidelines for optimizing plastic incorporation in road infrastructure.

Outcomes/Impacts:

The findings contribute to improved road performance, extended lifespan, and reduced maintenance costs, leading to more cost-effective infrastructure.  Life cycle analysis aids in balancing performance benefits with costs, promoting responsible plastic use in infrastructure. Collectively, these outcomes support policymakers, transportation agencies, and industry stakeholders in making informed decisions, fostering innovation in durable road construction, and advancing robust economy initiatives.
