Hveem Mix Design and Engineering Properties of Cold In-Place Recycling Mixtures
Nevada DOT has used Cold In-place Recycling (CIR) procedures for more than 20 years. The necessity of a performance-based criteria for CIR mix design is imperative to keep improving the overall conditions of the state roads. This study is part of a research based on developing new criteria for CIR …
