Conducting research from an accelerated pavement test facility

Inside me Last blogI am the importance of highway systems to our society in supporting the economies of countries around the world by continuously moving people and things from one place to another, and DOT and industry. Emphasizing the role that Accelerated Pavement Testing (APT) facilities play in providing, engineers have a common goal of having a lasting impact on tomorrow’s infrastructure with today’s decisions through research and quality data collection. Use the tools to achieve.

Since its construction MnROAD Another APT was built by the Minnesota Department of Transportation (MnDOT) on Interstate Highway 94 in 1993.I mentioned earlier Asphalt Technology National Center (NCAT) Alabama test truck originally built in 2000. Nowadays, you can see how the examples set by these two APTs are affecting other constructions.Florida Department of Transportation (FDOT) begins construction of 2.5 miles Concrete test roadThe long US-301 northbound segment is expected to open by the end of 2021.

These test road facilities offer comprehensive in-service performance of various pavement technologies and innovative concepts, taking into account interactions between factors such as traffic load, material properties, environmental conditions, design functions and construction practices. It provides the basis for evaluation. APT serves as the foundation for engineers to work on the implementation of new technologies. Place multiple APTs across the country instead of one, material, weather, and traffic from different regions.

Cooperation is an important element of the path towards conducting research conducted at these facilities. The African saying says: “If you want to go fast, go alone. If you want to go far, go with me.” This is a great way to collaborate and verify an implementation as a key factor in achieving an implementation, but it’s also important to understand that it’s time consuming and not always done quickly. is. To implement findings from advanced pavement testing facilities, it is necessary to establish alliances and associations that can group state agencies, industries, academia, and consultants.

An example of the National Pool Fund Association is Consortium for research and implementation of asphalt pavement (Managed by CAPRI, NCAT / Alabama DOT) and National Concrete Consortium (NC2Managed by Iowa DOT) National Road Research Alliance (Managed by NRRA, Minnesota DOT). Each group will use test tracks to engage stakeholders, advance pavement technology, and prioritize research and implementation activities to sponsor research through the federal highway agency’s (FHWA) pooled funding process. Discuss and develop. You can then use test tracks to strategically support the implementation of collaborative pavement research.

Another important factor is to use problem-solving skills that apply original thinking and creativity to group people who can work together. In the case of creativity, I think it is important to pay attention to the words of Susumu Minegama, who won the 1987 Nobel Prize in Medicine for discovering the genetic principles for creating antibody diversity. At the Nobel Prize Dialogue in Tokyo in 2017, he asked how people felt they could be more creative, he said, people were more curious at first, and then the immediate question. Have a constant urge to tackle, and answered that a third need to combine knowledge at least two different fields.

In my opinion, these three things play an important role in implementation. In particular, the third is very important for creating a diverse and unique working group with diverse backgrounds and unique perspectives. This is what I experienced in my involvement with the National Road Research Alliance (NRRA). The goal is to enable institutions across the country to achieve consistent benefits from actual road research with the help of highly talented people who work as a team to identify problems. , Complete the research project and implement the results. In the words of Glenn Engstrom, Managing Director of NRRA, “NRRA is at its best when it comes to bringing together a variety of enthusiastic and dedicated people to solve common problems.” Personally, I think this is indispensable for the realization of research results.

Dr. Emil G. Bautista, PE has more than 10 years of research on construction materials with a particular interest in highway design and construction, and the use of sustainable materials such as recycled asphalt pavement (RAP) and coal-burning products. An experienced civil engineer. (CCP) Pavement structure. He is currently working as one of the MnROAD project engineers at the Minnesota Department of Transportation (MnDOT). He is responsible for undertaking commissioned research with major pavement research partnerships led or participated by MnDOT. These research activities include many national, regional, and Minnesota research partners in the Road Research section of MnDOT at the Maplewood Institute. These partnerships include current and new future partnerships with the National Road Research Alliance (NRRA), National Center of Asphalt Technologies (NCAT), Minnesota DOT, and Minnesota Local Road Research Board (LRRB). He supports research agreements with NCAT related to asphalt mixing and pavement preservation and plays an active role in the leadership and support of these initiatives. He also provides expert-level knowledge of concrete / asphalt mixtures, performance testing, construction, and pavement performance. This is because it is usually related to the MnROAD research facility and to the research activities carried out by each partnership that supports the review of the MnROAD database. Provides information on future development and implementation of data quality checks to ensure that the data shared with research partners is of the research quality expected of the MnROAD facility.
