When to use a scrub seal
Scrub seals are a pavement maintenance tool designed to be utilized once a pavement has deteriorated down the Pavement Condition Index curve to a point between fair and poor. A scrub seal's highest value is obtained when crack sealing a pavement is no longer economically viable due to significant levels of cracking.
What is a scrub seal?
A scrub seal consists of an asphalt emulsion that contains a wear-resistant polymer and a rejuvenating agent that is then covered with well-graded aggregate.
The scrub seal process
- Prepare the roadway by sweeping. Optionally, the existing cracks may be cleaned out with compressed air and a heat lance in order to allow for improved crack filling performance of the asphalt emulsion.
- Apply the asphalt emulsion with a pressure distributor and scrub the material into the cracks utilizing a series of brooms pulled behind the distributor.
- Chip spreader applies the aggregate.
- Aggregate is rolled to aid in chip embedment.
- Loose aggregate is swept off the pavement.
- Preferably, the scrub seal is also fog sealed to aid in aggregate retention.
Benefits of a scrub seal
- Pavement has an improved wearing surface with appearance similar to a chip seal.
- The rejuvenating agent in the asphalt emulsion improves the low temperature flexibility in the top ½" of the existing pavement.
- The scrub seal process provides two applications in one: crack filling and chip sealing.

Evotherm
®
is
Ingevity
's water-free warm mix asphalt technology. Evotherm is derived from natural pine chemicals and offers advantages to asphalt contractors and road building engineers looking for innovative warm mix solutions. Its easy and ready-to-use formula provides comprehensive benefits that surpass conventional hot mix asphalt. Evotherm is approved by the Wisconsin Department of Transportation and meets the state's cold weather specification. It is being used across the state as a compaction aid for more consistent and increased densities; as a cold weather technology to extend the paving season; to reduce thermal segregation; and to extend binder life with lower temperatures and less oxidation.
Evotherm promotes adhesion at lower temperatures by acting as both a liquid antistrip and a warm mix additive. It's an easy-to-handle, pumpable liquid that can be added at the mix plant or at the asphalt terminal.
Over the last 12 years, customers have used the Evotherm technology to pave around the world more than 10 times. The U.S. National Center for Asphalt Technology (NCAT) has also evaluated Evotherm to show that it can withstand over 20 million ESALs on NCAT's test track with less than two millimeters of rutting.
Contact evotherm@ingevity.com to learn more about how Evotherm's benefits can stack up to deliver improved productivity and the highest overall value in the industry for your team.

Roland Machinery Company
reports that the Wirtgen Group recently unveiled its new 10-foot tracked Vögele Super 2000-3i. This refines the productive features of the Vision paver (5200-2i) it replaces and elevates asphalt paving to a new level of performance.
The Super 2000-3i introduces a new group of wheeled and tracked pavers that will eventually supplant the acclaimed Vision series. "The Super 2000-3i is designed primarily for use in highway construction and large-scale commercial applications, where power and productivity are paramount," says Roland's Mike Brunson. "It features a basic width of 10 feet, a maximum paving width of 28 feet and has a top placement rate of 1,540 tons per hour. It will lay a lot of asphalt quickly and efficiently."
Three main components define the power unit of the Super 2000-3i: its modern, liquid-cooled diesel engine; a splitter gearbox flanged directly to the engine; and a large cooler assembly. The powerful 6-cylinder Tier 4 Final engine rated at 250 horsepower drives the paver through even the most robust applications. It is also fuel efficient and has an
ECO mode
that is sufficient for many applications. A large cooler assembly ensures that the power unit always delivers its full output.
The Super 2000-3i has an innovative and reliable drive concept for accurate tracking. All drive components, including a three-phase generator, are supplied from the central splitter gearbox and operate at maximum efficiency. High-traction crawler tracks efficiently convert drive power into forward motion.
ErgoPlus 3
ErgoPlus 3
is the latest version of Vögele's operating system, now enhanced with a number of new ergonomic and functional features. With its new mounting system, the paver operator's console can be shifted even more conveniently and easily between the right and left sides of the operator's stand. In addition, it now has a large color display that ensures good readability even in poor lighting conditions.
"Vögele focused on the operator with the design of the Super 2000-3i," Brunson says. "Ergonomics, safe operation and operator comfort were key design elements. Vögele's commitment is to provide the highest quality machine and the industry's most reliable paver."

For asphalt plants that produce over 200,000 tons of mix a year and depend on consistent quality, the Troxler Model 3630 Moisture Measurement System (MMS) is an effective, real-time moisture measurement solution that can be used manually or integrated into any plant operating system.
The MMS is mounted on the virgin aggregate conveyor belt and allows plant operators to see the real-time moisture content as a percentage of the total combined aggregate. The plant operator can then adjust the percent moisture to a more accurate degree throughout the day, and moisture is not mistaken for aggregate on the weigh bridge. The ability to determine this difference makes the input of binder more precise and improves the mixture consistency.
Unlike existing moisture measuring devices, the MMS is mounted on the conveyor belt after the shaker or mixer and reads the combined aggregate's moisture rather than the moisture of individual cold feed bins. In addition, the noncontact nature of the system gives it a long life span, whereas other types of probes or sensors are prone to contact breakage.
Troxler's MMS is the most accurate, longest-lasting system on the market. It provides for more exact binder content, reducing the amount of natural gas used during production and resulting in higher-performing pavements. The MMS can help avoid that one failing job which results in a decrease or, even worse, a total remove and replace of asphalt laid.
There is no reason to leave the quality of your mix to chance! Know your inputs in real time and get improved results.
