Abstract: This study presents an approach to develop sigmoidal family pavement performance models (pavement performance ratings versus pavement age) for a pavement management system (PMS). Pavement condition data collected from ...

Abstract: This study presents a method to develop piecewise linear (PL) performance models for pavement condition data in a pavement management system (PMS). These condition data are usually ordinal and have more than two severity ...

Abstract: This research was conducted to determine pavement performance jumps after treatment, which are defined as the difference between pretreatment and post-treatment Pavement Condition Rating (PCR) values of asphalt pavements. ...

Abstract: The International Roughness Index (IRI) is an important pavement roughness measure that can be used to trigger appropriate maintenance treatments, approve new and rehabilitated roadways, and determine contractors’ performance ...

Abstract: Cold in-place recycling (CIR) is one of the most effective methods to rehabilitate asphalt pavements. In fact, most CIR roads have performed well at low cost in Iowa since the first CIR road was constructed in 1986. However, ...

Abstract: With a limited maintenance budget and unprecedented construction cost increases, many owner/agencies in the United States are beginning to rehabilitate existing distressed pavements. Cold in-place recycling (CIR) provides ...
