Abstract:This report is a summary of work performed by the Mobile Infrastructure Materials Testing Laboratory (MIMTL) as a part of the Joint
Transportation Research Program (JTRP) through SPR-3858. The development of the MIMTL began in February of 2014 and it became
fully operational by June of 2014. The MIMTL was deployed in the field for a total of 46 days. This report describes the activities of the
MIMTL as of December 2015. The MIMTL was involved in the field testing of concrete bridges, concrete pavements, and asphalt
pavements. This report describes the development of the mobile testing laboratory and provides some examples of how the MIMTL was
used. The main highlights of the MIMTL’s implementation are as follows:
• The MIMTL’s high mobility and extensive inventory of research equipment allowed graduate students and researchers to conduct
field studies on a wide range of infrastructure materials to accomplish the research objectives of their specific projects. More
extensive details of the background, objectives, methods, findings, results and implementation from those projects can be found in
the respective reports for those projects;
• The MIMTL supported a culture of safety that allowed students to work safely on jobsites in the State of Indiana ranging from
roadside interstates, rural country roads, to ready-mix batching plants, often around heavy equipment, traffic, and in close
quarters. During the operation of the MTIML described in this report, there were zero workplace accidents, and zero near misses
reported;
• The MIMTL assisted in technology transfer between the infrastructure materials experts at Purdue University and contractors and
suppliers in the State of Indiana. A wide range of new technologies evaluating infrastructure materials were utilized on a variety of
projects. On each of these projects, MIMTL researchers educated industry personnel (contractors and suppliers), agency personnel
(INDOT and local agencies), and consultants within the state. The MIMTL attended demonstrations with INDOT district and central
office personnel to further highlight capabilities as well as the emerging technologies;
• The MIMTL was established a joint investment with partners in industry, local agencies, and INDOT. Operated by the Joint
Transportation Research Program and the Local Technical Assistance Program as pay-per-use model, means this sustainable
venture will offer services to researchers, industry, or agency entities that can cover the pay-per-use costs.
