Learning Outcomes: | Overall Course Outcomes:
Materials Sampling and Field Testing is designed to benefit new and experienced Transportation Construction Inspectors (TCIs). The course will provde participants with an understanding of the processes that have occurred (material supply approval) and the processes that the TCI is responsible for having occur (material testing in the field).
The overall course outcomes are to ensure that inspectors can:
-- Correctly review certificates that are received onsite.
-- Identify appropriate resources for testing specifications.
-- Correctly complete TR-447 and TR-465 forms.
-- Understand the importance of, and methodology for, random sampling.
-- Know how to perform and/or supervise a variety of field tests.
Unit-Specific Learning Outcomes:
Unit I
-- Understand the relationships between the four (4) aspects of the Inspector's Daily Responsibilities model, as it applies to samplinjg and testing of materials.
Unit II
-- Correctly use a Source of Supply list and the appropriate Bulletins to verify that a contractor's proposed materials and suppliers have been approved.
-- Explain the items found on a CS-4171 form (Certificate of Compliance), and tell when it should be received onsite.
-- Explain the items found on a TR-465 form (Daily Bituminous Mixture Certification), and tell when it should be received onsite.
Unit III
-- List at least three reference resources for testing data, and tell when to use each source.
Unit IV
-- State three reasons why random sampling is required for specific materials.
-- Using the probability tqables from PTM-1, exhibit proficiency in sampling methodology for loose and core materials.
Unit V
