Abstract:This project’s purpose is to revise the UDOT accepted design methods for Cold In-Place Recycling so that they
better reflect field behavior and target the desirable attributes of the material. The previous design process failed to
adequately predict behavior related to temperature as well as did a poor job of characterizing return to traffic
performance. This project calls upon both laboratory observation and field experience to obtain optimization
between rutting, stripping and intermediate temperature cracking. It also ties down the constructability and return to
traffic parameters required by maintenance of traffic constraints. The new design process continues the use of
Marshall Stability and Tensile Strength Ratio to set rutting and stripping resistance. It further uses Semicircular
bending to set an intermediate temperature cracking parameter. New compaction/temperature and
compaction/gradation relationships are developed to help determine final density and emulsion targets. A new test
for emulsion set time is developed to prequalify emulsion construction performance. Modified BBR and Elastic
Recovery testing is used to establish cold temperature properties of recovered binder.
