RECENT NEWS
· Professional Development
Professor Goulias was appointed to the editorial boards of two international journals: - ICE Journal of Construction Materials, Institute of Civil Engineers , UK.
- Professor Goulias was elected Chair to the iSMARTi Association SC06 Publications, Paper Review and Awards Committee

· Awards, Invitations & Publications
- Dr. Goulias and Graduate Research Assistant Sushant Upadhyaya (PhD Candidate), received a "Highly Commendable Paper Award" at the 1st International Conference on Recent Advances in Concrete Technology," in Washington DC, on September 19-21, 2007. The paper and presentation entitled “Evaluation of in Place Strength of High-Volume Fly Ash Concrete”, by S. Upadhyaya, D. Goulias, and K. Obla, addressed a critical issue on concrete strength prediction (using maturity modeling) that the concrete community is phased with when using high volume fly ash (HVFA) as cementitious replacement materials.
- Prof Goulias and Graduate Research Assistant Megan Filo (MS Candidate) were invited and sponsored by NSSGA to present a paper at the 15th Annual ICAR Symposium, in Austin Texas, on April 9 - 12, 2007. The paper and presentation entitled " Effects on Mortar Properties of Fine Aggregates Failing to Meet ASTM C133 Requirements " by M. Filo and D. Goulias, included an assessment of a major problem that the construction industry is facing today since a staggering 90% of the fine aggregates for cement based mortars do not meet the current ASTM specifications.
· Upcoming Projects & Research Highlighted in National News
The following two upcoming research projects are expected to start soon:
- Establish Correlation between Aggregate Properties and Pavement Friction (PI)
State Agencies are currently facing issues related to aggregate quality in regards to pavement friction. Over the years, a number of quarries whose aggregates have typically achieved high friction ratings have dropped compared to current specification levels. Furthermore, increased variability in aggregate friction test results has prompted a review of the existing approach to aggregate friction evaluation. To address this issue SHAs have established on-going partnering and quarry inspections with aggregate suppliers, and conducted research that have as objective to evaluate existing aggregate data including laboratory test results and petrographic analysis with particular focus on the frictional properties of aggregates. It is the objective of this research project to: i) link laboratory based aggregate material properties to field measured pavement friction levels; and ii) develop revised aggregate material criteria for achieving various levels of pavement friction. (Ref. MDSHA)
- Catalog of Material Properties for Mechanistic-Empirical Pavement Design (Co-PI) The objective of this research is to develop a materials database for state use in relation to the new mechanistic-empirical pavement design guide (MEPDG) developed under NCHRP 1-37A. It is expected that the database will contain a full set of Level 3 data and some Level 1 information (primarily for asphalt binder properties, HMA dynamic modulus, and unbound resilient modulus). Specific Level 2 correlations for selected material properties will also be developed where possible. Objective of this material database is to provide the means for local calibration/ validation of the MEPDG.
- Passive Wireless Concrete Maturity Monitor (PI)
The recently funded MIPS research project Passive Wireless Concrete Maturity Monitor (PI) undertaken in cooperation with ASR&D was featured by the national news media in view of the rush-hour collapse of the Interstate 35W bridge in Minneapolis. While the primary objective of this research project is the development of an innovative concrete maturity meter that overcomes a lot of the limitations of current systems available in the market increasing functionality, reliability, and reducing costs, it is expected that such a system will be able to be used for long term monitoring of temperature profiles and gradients so as to be used by infrastructure managers to analyze the structural health of the infrastructure and eventually predict incipient failures far enough in advance to allow for remedial actions.
