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 contains three modules:
1 Introduction to Cold In-place Recycling;
2 Cold In-place Recycling Full Production; and
3 Cold In-place Recycling Post Production.

This course will provide the inspector with a background and proper inspection procedures when placing cold-in-place hot mix asphalt.

This course offers professional development hours (PDHs). You will see the PDHs on your course completion certificate, which also serves as documentation of your attendance. PDH requirements vary, therefore, it is up to you to determine whether or not this particular course qualifies under your State or board requirements.

Training level: This training is recommended for the Transportation Curriculum Coordination Council levels II, III, and IV.

Target audience: 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 cold in-place recycling.

Learning outcomes: Upon completion of the course, participants will be able to:
• Explain what CIR is and why it is used;
• Describe what happens during pre-production;
• Explain how the control strip helps determine compaction procedures and why it is needed;
• Identify the factors that can influence a CIR mix;
• Describe important considerations during placement, compaction, and finishing;
• Explain the importance of curing and maintenance on the quality of a CIR surface; and
• Describe what happens once the surface is finished.
