Abstract:

The high cost and environmental impact of traditional pavement rehabilitation has 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. Therefore, this research has been undertaken with the objective to develop a new mix-design procedure for CIR through laboratory evaluation and limited field verification. The project focuses on partial-depth CIR using asphalt emulsions as the recycling agent. The modified Marshall mix design recommended by the AASHTO Task Force No. 38 was evaluated and found to be inefficient. Therefore, a new volumetric mix-design has been developed utilizing the Superpave gyratory compactor and technology. It requires that specimens be prepared at densities similar to those found in the field. The performance of CIR mixtures prepared and constructed in accordance with the new mix-design has been evaluated in the laboratory as well as in the field. Creep compliance and strength of the mixtures have been determined using the Indirect Tensile Test (IDT) in an effort to evaluate the resistance against low-temperature cracking.
