Course Description:
This course will cover statistics in a very basic and practical
manner. Examples from everyday life will be used to illustrate
the concepts presented. It will explain the importance of variability
and how it affects all aspects of asphalt concrete production
and placing. The importance of random sampling will be explained
along with the importance of precisely following all stipulated
sampling and testing procedures.
The course will provide a basic understanding of the important
statistical measures of mean and standard deviation, and will
explain how the actions of asphalt technicians can affect these
measures. Course participants will obtain an understanding of
why asphalt specifications are written as they are, and will also
learn how material variability leads to risks to both the contractor
and the owner.
The course is intended to provide a basic understanding of the
importance of statistics and variability in the day–to–day activities
of every asphalt technician.
Course Instructor:
Jim Burati will serve as the instructor for the course. Jim is
the Director of the SC Transportation Technology Transfer Service.
He has over 25 years experience in the development and analysis
of specifications for asphalt materials. He has written training
manuals on quality assurance (QA) specifications and process control
for the National Highway Institute (NHI) and the Federal Highway
Administration (FHWA).
Jim
is the developer of a week—long NHI course on QA. He has also
taught statistical specification concepts to numerous state highway
agencies. For the FHWA Jim has recently completed a manual that
serves as a guide for all states to use to develop QA specifications.
Jim assisted the SCDOT in developing their initial QA specification
for hot mix asphalt as well as the new SCDOT asphalt specification
that will be implemented in the upcoming construction season
Who Should Attend:
Hot mix asphalt technicians, asphalt roadway technicians, and
those who supervise such personnel should attend. Anyone that
is associated with asphalt production and paving operations can
benefit from the concepts presented in this course. While all
the examples will be in the asphalt area, the concepts presented
in this course apply equally well to all highway and construction
mate
Types of Specifications:

Why is it so important to follow procedures?
Statistical Measures
What are a mean and a standard deviation, and why should I care?
Why is a normal distribution normal?
