Abstract:

The high cost and environmental impact of pavement rehabilitation have led to an increase in the use of cold in-place recycling (CIR) as an effective alternative to other rehabilitation strategies. However, currently there is not a universally accepted or standard mix design for CIR. This project is being undertaken with the objective of developing a performance-based mix-design procedure for CIR through laboratory evaluation and limited field verification. This project focuses on partial-depth CIR with asphalt emulsions as the recycling agent. After modified Marshall mix design recommended by AASHTO Task Force 38 was evaluated, a Superpave gyratory compactor and technology were used to develop a volumetric mix design. This requires specimens to be prepared at densities similar to those found in the field. It also suggests that specimens should be cured at 60 deg C (140 deg F) for 24 h. This allows for the most consistent specimens and most effectively utilizes the time of laboratory personnel. It is also recommended that the resilient modulus of specimens prepared with the new mix design be used for pavement structural design.
