OFFICE OF MATERIALS MANAGEMENT
The Asphalt Materials section of the Office of Materials
Management conducts testing and personnel approvals in support of ODOT
Districts project contract administration, contractor and supplier approvals,
material investigations, as well as implementation of new specifications and
technology. Also, in conjunction with the asphalt industry, the
section works to further the expectation of quality paving through
specification development and evaluation of contractor procedures.
The section is divided into two distinct roles. One area
conducts testing and administers the asphalt binders program for ODOT. These
binders are used in asphalt paving, chip sealing, microsurfacing, joint sealing
and various other applications of asphalt products in roadway construction. The
other area within the asphalt section conducts testing and administers the
approval of asphalt mixtures and personnel for a variety of specifications, and
assists districts in pavement failure forensics and pavement applications.
Asphalt Materials section is AASHTO accredited and can perform all of the
standard AASHTO and ASTM tests relating to asphalt mixes and asphalt
binders. The section also conducts a variety of specialized tests
including gyratory compaction, loaded wheel rut and fatigue, cracking, abson
recovery, reflux and moisture damage tests.
