ICTD 2018 is organized by The Transportation & Development Institute (T&DI) with the goal of facilitating the exchange of information, knowledge, and best practices among transportation and development practitioners and researchers, public infrastructure owners, policy makers, government engineers and planners, operations managers and leading academics from around the world.
“Emerging Technologies: Impacts on Transportation & Development” is the central focus for this year’s conference and gives transportation professionals a chance to network, share ideas and advance the knowledge on the impact of technologies on transportation and development. “With the rapid growth in Connected and Autonomous Vehicles (CAVs), V2V and V2I communication, on-demand location-based transportation, and other emerging technologies, there is a critical need to assess and prepare for the impact of these technologies on transportation and development as a whole” it states on the conference website. An outstanding panel of speakers and exhibitors have been assembled to discuss the impact of new technology on mobility, safety, transit, airports, freight, pavements and other key elements of transportation infrastructure and operations.
If you are headed to the conference, we invite you to stop by our booth to learn about our FastPatch concrete repair products and how agencies all over the United States and around the world are using it for service on major highways, airports, bridges, railroads and more.
It happens to us all. We’re on a relatively smooth ride and suddenly- BAM. Your vehicle dips a few inches and you’re left wondering how much damage has been done on your brand new tires. Chances are, you just hit a pothole. You’ve heard the term and if you’re like most people, you detest them. Potholes are certainly a nuisance, but they can often be dangerous and will require fast repair.
But what are they? And how do they get fixed?
What causes a pothole?
Potholes are created when the top layer of pavement and the material beneath—called the base or sub-base—cannot support the weight of the traffic. Two factors are always present in such a failure: TRAFFIC and WATER. The “gestation period” for a pothole includes:
1) Snow-melt or rain seeps through cracks in the pavement and into the sub-base; if the moisture cannot adequately drain away from the sub-base and soil underneath, it becomes saturated and soft.
2) Trapped moisture is subjected to repeated freeze/thaw cycles–and with each occurrence the expanding ice lifts and cracks the pavement more. The passing traffic weakens the pavement, cracking it further.
3) As temperatures rise and the ice melts, a void is left under the pavement. This void collects more water, and during the next freeze, the void will enlarge.
4) Vehicles driving over the weakened pavement pound it until the surface breaks and collapses into the void below, thus creating a pothole.
Why are they called potholes?
According to the late trivia expert and syndicated columnist L. M. Boyd, pottery makers in l5th and l6th century England would take advantage of the ruts that wagon and coach wheels gouged into roads. Anxious for a cheap source of raw materials for making clay pots, the potters would dig into the deep ruts to reach clay deposits underneath.
Teamsters driving wagons and coaches over those roads knew who and what caused these holes and referred to them as “potholes.”
What affects pavement life?
Pavement life is influenced by many factors: vehicle loading (axle loads, tire pressure and gross vehicle weight [GVW]), traffic volume and mix, environmental conditions, topography, subgrade condition, initial pavement design and construction practices, maintenance activity and pavement age.
Traffic volume has increased significantly and this trend will continue —but few new lane-miles have been added to the nation’s highway, road and street network and are not expected to keep pace with the increased demand.
The decision and capability to patch potholes is influenced by: current weather; traffic conditions; imminent scheduled roadway construction; major maintenance work or utility work in the roadway; availability of personnel, equipment, and materials, and the demands of the traveling public.
How are potholes repaired?
Pothole patching is performed either as an emergency repair during harsh conditions or as routine maintenance scheduled for warmer and drier periods. Typically, emergency repairs are done only when a pothole presents a substantial safety or traffic operational problem and must be urgently corrected.
For example, a large pothole on a major arterial has contributed to collisions by causing drivers to swerve to avoid or lose control after hitting it. Or, one or more large potholes hinder the flow of traffic causing unusual slow-down and congestion. Potholes near activated traffic signals may expose embedded loop sensor wires, and when they break, the signals will not be responsive to traffic demands.
Emergency repairs usually are done in heavy traffic and can be a safety risk to maintenance workers. Repairs that are more permanent can be scheduled for times when weather and traffic are more conducive to safe operations.
There are a number of standard pothole repair methods used for any asphalt paved street or road, but here is a demonstration of how FastPatch products, a division of WVCO, can be used to repair a common pothole.
“China is developing its high-speed train technology fast enough to catch up with the best by, among other things, funding research teams to develop advanced monitoring and early warning systems, and quake-resistant technology to ensure the safety of high-speed railways. Even in environmental protection, China has gained enough experience while building the railway that connects Lhasa, Tibet with Qinghai province.” – Professor Zhai Wanming
Professor Zhai Wanming is a railway engineering dynamics specialist who fills the roles of chairman of Academic Committee of Southwest Jiaotong University, director of the Train and Track Research Institute, elected member of the Chinese Academy of Sciences, and editor-in-chief of the International Journal of Rail Transportation. With all that in mind, it should be safe to say that he has played a fundamental role in the development of safety protocols and frameworks for China’s high-speed rail system and abroad.

Professor Wanming’s endeavors include developing a method for analyzing and assessing the safety of high speed trains passing through bridges and the development of a vehicle-track coupled dynamics framework, used throughout the country. As China expands their high-speed rail system, Zhai Wanming’s processes have been used in over 20 large-scale field engineering projects to date. His work also extends to over 160 papers he has published on the subject and such books as “Vehicle-Track Coupling Dynamics” and “Advances in Environmental Vibration.”
Zhai has won the first-class prize of Science and Technology Progress Awards by the Ministry of Education in 2003 and the first-class prize of National Award for Science and Technology Progress by State Department in 2005. He received the achievement prize of Zhan Tianyou Railway Science and Technology Award in 2003, as well as several honors including the National Expert with Outstanding Contribution in 1994 and the Award of Chinese Youth Scientist in 2006. Lastly, he was named Chang Jiang Professor by the Ministry of Education (the highest honor issued to an individual in higher education by the Ministry of Education).
Over the course of several decades, Zhai Wanming has brought considerable advances to railway engineering and safety both in China and the world over through his frameworks, systems, and publications. It is this unwavering drive to improve the way we handle railway transportation systems that has made Zhai Wanming our “Featured Innovator of the Month.” We hope you all get the chance to hear him speak at International Conference on Transportation and Development, it will not be one to miss!

“The problem with cracks in concrete is leakage. If you have cracks, water comes through — in your basements, in a parking garage. Secondly, if this water gets to the steel reinforcements — in concrete we have all these steel rebars — if they corrode, the structure collapses.” – Professor Henk Jonkers, Delft University of Technology, Netherlands.
Concrete repair products is a subject we know a lot about! We’ve seen first hand the problems that slow-building cracks can create. But what if damaged concrete could heal itself? That’s exactly what Professor Henk Jonkers is working towards with his work into bioconcrete — concrete that heals itself using bacteria.
Jonkers was inspired by the human body in his work, which works by adding a limestone-producing bacteria agent to the concrete mix. As air is let in through cracks and damage to the concrete, the bacteria is activated and begins producing limestone and patching out the cracks.”You need bacteria that can survive the harsh environment of concrete. It’s a rock-like, stone-like material, very dry,” says Professor Jonkers.
This process could play a pivotal role during construction, when small imperceptible cracks form as concrete is laid. By self-patching immediately, this bioconcrete could prevent long term damage. You can see some of the self-healing concrete at work below.
To date, bioconcrete has only been able to heal cracks up to a very slim 0.8 mm wide in about three weeks, but it can also be sprayed in cracks of regular concrete to use its mending powers. It will certainly be interesting to hear what the future holds for bioconcrete, and if its European Inventor Award finalist nomination is any indication, we’ll be hearing much more soon!
It’s this ingenuity and forward-thinking approach to finding new unexplored solutions to potentially long-term and expensive problems why we have named Professor Henk Jonkers our “Featured Innovator of the Month.” We look forward to hearing more of his work in bioconcrete in the future!

FastPatch was used to conduct a repair on a scale chair in the CSX Queensgate Yard in Cincinnati, Ohio, one of the largest rail classification facilities in North America. Queensgate Yard, considered one of the most productive hump yards on the CSX system, is located along the Mill Creek west of downtown Cincinnati and covers approximately 70 miles of track. Constructed at a cost of over 71 million dollars with the purpose of consolidating several small yards in the area, the yard was dedicated on October 20, 1981. In 2012, our POLYQuik Division conducted a repair on a scale chair using a total of 5 lifts and 14 bags of gravel. The FastPatch procedure took 90 minutes to complete.
The following presentation illustrates the repair process:
Chair prior to removal
Old material and concrete removal
Area prepped and primed before application
Chair was set in place prior to any work being done
Gravel was poured and FastPatch dispensed around chair. First lift was 6 inches. Anchor bolts were set in place while product was being applied.
Chemical was allowed to cure for 55 minutes before train cars were allowed on the scale.
