Crushed Hydraulic Cement Concrete Adjacent to Underdrains

The objectives of this field study are as follows: (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 Virginia Department of Transportation (VDOT) to generate specifications to allow the use of CHCC/virgin aggregate blends as unbound aggregate when geotextile is present in the drainage system.
