What Exactly Are “Potholes” Anyway?

Potholes and Concrete RepairStory Source: AWPA

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.

How FastPatch Became an Innovative Solution for Concrete Repair

FastPatchDPROur roots are in wood products, but the Willamette Valley Company is much more than that. We are also leaders in providing high-performance solutions in a range of industries. Just over a decade ago, our company was approached by key transportation professionals who needed fast-curing and ultra-tough materials for repairing roadways and bridges. They were weary of antiquated repair materials that were non-flexible, required water, and were labor intensive to install.

Our solution? FastPatch.

The introduction of this groundbreaking line of concrete repair solutions was a significant leap forward in technology. The product proved to outperform and outlast traditional products, plus it was easier to install with our custom dispensing machine and easy-to-use kits.

FastPatch been approved by government agencies all over the United States for service on major highways and has been used to repair airports, highways, bridges, railroads, and other various applications throughout the United States and around the world. Its products can repair everything from broken concrete and asphalt, spalls, potholes, joints, driveways, highways, bridge decks, parking lots, Cracks slab repairs, ramps and loading docks, warehouse floors, post anchors, and trip hazards. It has been used by everyone from Public Works & Engineering/Construction industry professionals to home improvement “DIYers”.

To reduce waste, FastPatch uses recycled and renewable materials to repair existing materials. It is 100% solids and does not contain any volatile chemicals. Repairing with FastPatch, rather than removal, eliminates disposal costs and excess waste. FastPatch DPR (Distressed Pavement Repair) for example, is created from 80% recycled and renewable materials. Over 50 bottles of recycled glass are used in a single kit and the polymer is a blend of renewable bio-based materials.

A case study performed on Caltrans Maintenance in Santee, CA  states “FastPatch is easily dispensed, fast curing, flexible, and has excellent adhesion. Currently, there is not a material on the market that can do the same thing as FASTPATCH and have the color of concrete. FastPatch is cold applied and allows Maintenance to repair all concrete distresses in the lane closure, which includes Spalls, Corner breaks, First & Third stage crack, and transverse & longitudinal joints.” –

Though our roots are in the wood and railroad products industry, our groundbreaking line of concrete repair solutions is in high demand. It all began more than a decade ago when we were approached by key transportation professionals who needed fast-curing and ultra-tough materials for repairing roadways and bridges.

Our solution was the development of FastPatch.

FastPatch is a significant leap forward in technology from antiquated “powder” type repair materials that are non-flexible, require water, and are labor intensive to install. The product proved to outperform and outlast traditional products, plus it was easier to install with our custom dispensing machine and easy-to-use kits.

It didn’t take long for FastPatch to be adopted by several States D.O.T.s such as California, Texas, Georgia and Washington among others. Today FastPatch is used to repair airports, roads, driveways, highways, bridges, railroads, parking lots, ramps and loading docks, warehouse floors, and other various applications all over the world (e.g., Australia, China, South America, Canada, Mexico, UK).

Product use has become so widespread, we launched a new website dedicated to this product. The website is filled with resources for everyone from Public Works & Engineering/Construction industry professionals to home improvement “DIYers”. It is also filled with helpful data sheets, FAQs, and case studies.

We hope you will visit our new website and contact us with any questions and feedback: FastPatch@wilvaco.com or 800-333-9826. You can check out our videos all in one place at vimeo.com/fastpatch.

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:
