| 摘要： | This report documents the validation of the single-point notched constant tensile load (SP-NCTL) test as a measure of slow crack-growth resistance under sustained loading of high density polyethylene (HDPE) resins - including compositions containing postconsumer resins (PCR) - that are intended for nonpressure drainage pipes and the calibration of minimum slow crack-growth resistance requirements with the results of actual experience. The contents of this report are, therefore, of immediate interest to both highway and rail transit professionals responsible for designing, installing, inspecting, maintaining, and upgrading nonpressure drainage pipes. The report is also of interest to those charged with specifying materials for such pipe, setting budgeting goals, and making policy. |
