摘要: |
One element of quality assurance for laboratory testing that was deemed to be of key importance by the strategic Highway Research Program (SHRP), was the American Association of State Highway and Transportation Officials' accreditation program (AAP) for laboratories. All laboratories providing long-term pavement performance (LTPP) testing services were required to be accredited by AAP. It was determined that supplemtnal programs should be designed to provide assurance that quality test data would be obtained by using approaches similar to those provided by AAP for other tests. One supplemental program was the Portland Cement Concrete (PCC) Core proficiency Sample Program which was designed to provide precision data concerning the static modulus of elasticity, poisson's ratio, splitting tensile strength, and compressive strength. This document provides a description of the latter. |
