LTPP (Long-Term Pavement Performance)

LTPP, or Long-Term Pavement Performance, is a research initiative that studies how roads and highways hold up over time. It involves collecting data on pavement conditions, materials, traffic loads, and environmental factors through testing and monitoring. The goal is to understand how different factors impact pavement durability and to develop better strategies for maintenance and design. By analyzing this information over many years, engineers can improve roadway longevity, safety, and cost-effectiveness, ensuring infrastructure remains functional and safe for users while minimizing repair expenses.
