Cost-effectiveness analysis of chip seal with and without millings
Millings or old pavement materials (also known as reclaimed asphalt pavement) are used in pavement base and surface course mostly for rehab and reconstruction processes. Millings can also be used in pavement maintenance such as chip seal. However, it is not known whether chip seal with millings are cheaper than chip seal with virgin chips considering their lifetime performance. In this study, life cycle cost of chip seal with and without millings was determined from data gathered by surveying three transportation Districts in New Mexico. Performance plot over time was used to evaluate the benefit and cost-effectiveness index (EI). For all districts, chip seal with millings has higher EI compared to chip seal with virgin aggregates.
