New Course – Full Depth Reclamation (4.5 hours) Full Depth Reclamation (FDR) is a rehabilitation technique in which the full thickness of the asphalt pavement and a predetermined portion of the underlying materials (the base, subbase, and/or subgrade) is uniformly pulverized and blended to provide an upgraded, homogeneous material. This course will start with the basics of FDR and then move through pre-production and reclaiming to post-production activities. This course is intended for local, county, and state owner agency technicians and inspectors. It is also useful for individuals who need awareness or basic understanding of FDR of hot mix asphalt. This course contains four modules:
- Introduction – This module introduces the topic of FDR of pavements.
- Pre-production activities – This module discusses pre-production activities associated with FDR, including the pre-production meeting, roadway preparation, and FDR equipment needs.
- Reclaiming the pavement – This module covers establishment of a control strip, pulverization of material to be reclaimed, and the various methods and agents used to stabilize reclaimed materials.
- Post production – This module covers the steps that need to be taken following reclamation.
Hot In-place Recycling (2.5 hours)
Hot in-place recycling (HIR) is a pavement preservation and corrective maintenance technique that consists of heating and softening the existing asphalt pavement. When combined with an asphalt overlay, HIR can be classified as structural rehabilitation. The HIR techniques described in this training provide owner agencies with cost-effective and sustainable methods to repair their aging pavements. HIR processes have been used on all functional classes of roadways. When properly designed, specified, and constructed, HIR methods can result in significant cost savings as compared to conventional maintenance operations, while reducing carbon dioxide emissions. This course is 2.5 hours in duration.
Inspector Training for Cold In-Place Recycling (4 hours)
Cold in-place recycling (CIR) is a method of reconstructing any flexible pavement where the need arises from structural failures. These failures include transverse cracking, wheel rutting, potholes, surface irregularities, or a combination of these. The proper selection of a CIR process, in conjunction with good specifications and quality construction, are all important in the long-term performance of the pavement rehabilitation. This series on CIR will introduce each method and provide a background on when, how, and why that method is selected/used. This training is meant to provide an overview of CIR, including an explanation of the pre-production inspection, completing the control strip, full production of the mix, mix placement, curing and maintenance, acceptance testing, and measurement and payment. This course is 4 hours in duration.
