    Recycling - Federal Highway Administration

    IntroductionCase HistoriesSpecifications and QC/QASummaryReferencesHot in-place recycling (HIR) is a hot process in which the existing asphalt pavement material is recycled in place. Typically, the pavement is processed to a depth of 20 to 40 mm (¾ to 1½ in).(1) The deteriorated asphalt pavement is heated and the softened material is scarified and mixed with virgin aggregate and/or recycling agent and/or virgin asphalt mix. In the single-pass method, the restored existing pavement material is combined with virgin materials and compacted in a single pass. In

    Recycling - Federal Highway Administration

    IntroductionSummaryReferencesHot in-place recycling (HIR) has been described as an on-site, in-place method that rehabilitates deteriorated asphalt pavements and thereby minimizes the use of new materials.(1) Basically, this process consists of four steps: 1. softening of the asphalt pavement surface with heat; 2. scarification and/or mechanical removal of the surface material; 3. mixing of the material with recycling agent, asphalt binder, or new mix; and 4. laydown and paving of the recycled mix on the pavement surface

    Lower Temperatures, Lower Costs, More Opportunities.Better PerformanceGood For Workers, Good For The environment.WMA production methods use temperatures 30 to 120 degrees Fahrenheit lower than traditional hot-mix asphalt. Because less energy is needed to heat the asphalt mix, less fuel is needed to produce WMA. Fuel consumption during WMA manufacturing is typically reduced by 20percent.In paving projects, the greater the temperature difference between the asphalt mix and the outside temperature, the faster the mix cools. Since faster cooling effects durability, cold ambient temperatures adversely affect
