Crushed Hydraulic Cement Concrete Adjacent to Underdrains

Project No: 113425

Target Completion Date: June 30, 2024 Pavements

About the project:

The objectives of this field study are: (1) to confirm the validity under field conditions of Crushed Hydraulic Cement Concrete (CHCC) behavior (fines migrate and tufa precipitates but geotextile continues to function as a filter and does not prevent water from flowing through) observed in the laboratory in a prior study; (2) to develop a threshold percentage for the blending of CHCC with virgin aggregate, and (3) to provide recommendations to VDOT to generate specifications to allow the use of CHCC/virgin aggregate blends as unbound aggregate when geotextile is present in the drainage system.
