This course offers professional development hours (PDHs). You will see the PDHs on your course completion certificate, which also serves as documentation of your attendance. PDH requirements vary, therefore, it is up to you to determine whether or not this particular course qualifies under your State or board requirements. Course overview: AASHTO Designation: T 312: Preparing and Determining the Density of Asphalt Mixture Specimens by Means of the Superpave Gyratory Compactor explains how to perform all of the necessary set-up procedures, complete the steps in the test method, make all necessary calculations, and complete the documentation required to prepare and determine the density of an asphalt mixture using the Superpave gyratory compactor. This training covers the following topics:
Significance and use;
Apparatus and preparation of apparatus;
Asphalt mixture preparation;
Compaction procedure;
Density procedure; and
Density calculations. Training level: This training is recommended for the Transportation Curriculum Coordination Council levels I and II. Target audience: This training is designed for plant technicians, private lab, DOT technicians, or contractor employees who are qualified to perform acceptance tests including Preparing and Determining the Density of Asphalt Mixture Specimens by Means of the Superpave Gyratory Compactor. It is also useful for laboratory and personnel assessment technicians. Learning outcomes: Upon completion of the course, participants will be able to:
Explain the purpose of the T 312 test method;
Describe the equipment used in the T 312 test method;
List the steps to prepare the apparatus for the test procedure;
Explain which items may require periodic verification of calibration;
Describe the process to prepare the HMA mixture for the gyration test when the sample is laboratory prepared;
Describe the procedure for compacting the prepared HMA mixture;
List the density procedures that are determined after the mixture has been compacted;
Calculate the uncorrected relative density and the relative density; and
Explain how to close out the T 312 test.
