From page 1...
... The working hypothesis is that good quality pipe can be manufactured from such blends if critical material properties that affect pipe performance and durability, such as strength and structural properties, density, melt index, environmental stress-crack resistance, and thermal stability, are consistently maintained at specified levels in the blends. At present, AASHTO specifications do not permit the use of recycled HDPE in the production of corrugated drainage pipe.

... Much better properties can be obtained by blending recycled resins with virgin resins lower in density and higher in stress-crack resistance than the virgin pipe resins. It seems clear from the results that pipe made with significant amounts (>50%)
