Wisconsin Asphalt Industry Insider is a platform for WAPA members to share what's new and exciting at their companies with pavement owners, operators, and contractors across our state. We hope you find this information useful!
The Summer 2019 issue of Asphalt Institute's
highlighted rubblization in its cover story and prominently featured WAPA member
The article, "Rubblizing to rehabilitate existing pavements
" discusses rubblization as the most cost-effective option to rehabilitate badly distressed concrete pavement in West Virginia. Contractors in the state opted to use the multihead breaker (MHB) manufactured by Antigo. As the article details:
In order to optimize the rubblization process, contractors worked closely with Antigo personnel to customize the equipment setup and operation for each particular project.
The MHB Badger BreakerŪ has sixteen drop hammers mounted laterally in pairs with half of the hammers in a forward row and the remainder diagonally offset in a rear row providing continuous breaking of up to thirteen feet wide. The hammers vary in weight from 1,200 to 2,000 pounds with the choice of hammers utilized based on the energy required to adequately fracture the particular concrete pavement. The drop height of each pair of hammers is independently adjustable to ensure the proper amount of breaking across the width of the machine. The travel speed of the MHB is adjusted to vary the spacing between hammer hits.
Matt Shinners of Antigo talked about factors that should be considered when setting up the MHB for a specific project: "The support provided by the subgrade and base significantly affects the particle sizing that is achievable. Generally, the better the support the smaller and more consistent the particles can be produced. The combination of hammer weights, drop heights and machine speed allow the MHB to perform the optimum rubblizing pattern for each particular combination of concrete pavement and subgrade/base support to meet the specification requirement for particle size."

Technical Breakout Sessions
, including the following:
- Stone-Matrix Asphalt (SMA)
SMA was developed to provide heavily trafficked roads with a durable, rut-resistant wearing course using a gap-graded aggregate structure and a modified asphalt binder at elevated asphalt contents. This session will illustrate why SMA has been used worldwide for almost 50 years, and capture advancements in mixtures and pavements over the past 25 years since the first SMA pavement was placed in Wisconsin.
- Air Quality/Emissions
This session will provide a review of applicable asphalt industry rules and compliance expectations with information on the general operation permit revision process, state department resources, and an invitation for feedback going forward.
- Asphalt Pavement for Recreational Facilities
This session will address the important factors that need to be considered when designing and constructing recreational facilities such as running tracks, tennis courts, and golf cart paths. These types of facilities do not carry heavy loads and therefore need to be built differently than roads and freeways. Specific mixture requirements are needed to build a durable pavement that will resist environmental distresses such as cracking and raveling. Restricted work areas also present challenges that will be discussed during this session.
- Back to Basics: Aggregates
The aggregate skeleton is what provides the majority of strength and stability in an asphalt mixture. Choosing the right gradation and knowing how aggregate properties impact mixture performance are critical to ensuring pavement performance. This session explores how the size and type of aggregates can impact asphalt mixture design and performance.
- Back to Basics: Mix Design
Building on an understanding of binder properties, aggregates, and volumetrics, this session provides a basic overview of the steps for asphalt mixture design using the Superpave method, including discussion of hoy recycled material affects mix design considerations.
- Ethics Training
Back by popular demand, this session will focus on the fundamental canons of professional conduct and other appropriate administrative rules and regulations. The discussion is designed to demonstrate a working knowledge of professional ethics and satisfy the requirement for "professional conduct and ethics".
As always, please don't hesitate to contact us if you have any questions or if there is ever any way we may be of assistance. Thanks again, and see you in December.
