Abstract:

CIR has become a useful tool in pavement rehabilitation due to cost savings. UDOT wishes to

improve the reliability of the process as well as improve the final outcome. A balance is achieved

between fracture durability and rutting resistance by controlling void content and added emulsion. This

balance is well reflected in the current mix design method but has proven difficult to achieve in the field.

Observation of field methods has pointed toward modifications to the mix design procedure as well as

to tests providing same-day feedback to the CIR process.

SR 32 is the second field project where a variety of tests were used to control the process

consistency and quality as well as the release to traffic conditions. The Dynamic Cone Penetrometer

(DCP) along with the Shear Vane test are further validated and a new test protocol using the Marshall

Hammer is developed. Recommendations for test thresholds are made.

Recommendations are made for control of both longitudinal and lateral density. Roller patterns

are recommended. Emulsion break temperatures are evaluated leading to best compaction practices.

Recognition of system sensitivity to temperature results in proposed changes to the mix design

procedures. Specification changes are recommended with respect to the pickup machine and paver.
