A Practical Approach to Managing Density: #T24

Tue. March 17 from 7:30 AM - 9:00 AM in Room 310


Meeting and exceeding density specifications is critical to success on today's paving jobs. However, managing the rolling and compaction operation continues to be the most misunderstood aspect of the paving operation. Contractors often "chase density" without understanding and fixing the root cause(s) of why density is not being consistently achieved. It doesn't have to work this way and Todd Mansell from Caterpillar, Inc. shows attendees the why and how in this session.

Using ThinLay Asphalt Applictions to Increase Pavement Life: #W15

Wed. March 18 from 7:30 AM - 9:00 AM in Room 307


 Pavement owners want to have alternatives to major rehabilitation in their pavement management toolbox. The use of thin asphalt overlays (ThinLays) has proven to be a method of extending the life of pavement structures that are still in serviceable condition. ThinLays are generally 1.5 inches or less in thickness with small nominal maximum aggregate size. This session will provide attendees with the background of ThinLay applications, materials required and a contractor perspective about the production and placement operation. Presenters are Chuck Fuller from Ramming Paving and John Hickey from Asphalt Pavement Association of Oregon.

What's the Latest on Intelligent Compaction: #W14

Wed. March 18 from 7:30 AM - 9:00 AM in Room 308


This session will begin with a presentation by two industry members of the FHWA Intelligent Compaction task force who will provide background on progress in the technology. What are the elements of Intelligent Compaction? What is the difference between Intelligent Compaction for GPS on rollers and real time density measurements? What benefit to the contractor does Intelligent Compaction bring to the industry? A group of representatives from equipment manufacturers will participate in a panel discussion to answer questions from the audience.

On hand to facilitate discussion will be:

Manfred Darscheid: Bomag

Todd Mansell: Caterpillar

Ed Conlin: Sakai

Kevin Garcia: Trimble

Mark Eckert: Volvo

Tim Kowalski: Wirtgen


Best Practices for Construction of Longitudinal Joints: #W34

Wed. March 18 from 2:00 PM - 3:30 PM in Room 307 | Thu. March 19 from 7:30 AM - 9:00 AM in Room 307


 Longitudinal joints are an inherent weak spot in an asphalt pavement. Where two passes of the paver intersect creates an area of lower density due to paving operations. The life of the pavement can be significantly compromised if the joint is not constructed properly. This session from Greg Harder with The Asphalt Institute, offers state-of-the-practice recommendations for constructing high quality longitudinal joints.


Compaction 101: Getting the Roller Pattern Right and Staying Consistent: #W35

Wed. March 18 from 2:00 PM - 3:30 PM in Room 314 |Thu. March 19 from 7:30 AM - 9:00 AM in Room 314


Compaction is the last key step in asphalt pavement construction and is a critical element in asphalt pavement performance. Compaction not only affects performance but often determines how much or if the contractor will get paid for the work. Chuck Deahl from Fat Boy Roller Company, shows attendees in this best practices in order to achieve quality pavements profitably.

Black is Green:

Whether you like it or not, customers want to know that your operations are friendly to the environment. These sessions will help you reduce your carbon footprint as a paving contractor.

State-of-the-Practice for Porous Pavements: #T14

Tue. March 17 from 7:30 AM - 9:00 AM in Room 315


Porous asphalt pavements are being used by many owners to construct asphalt pavements that become part of the stormwater solution, reducing runoff, improving infiltration and saving land. The performance of these pavements depends on proper design and construction. In this session you Jeff Graf from Maryland Paving and Kent Hansen from NAPA give attendees a thorough understanding of porous pavement design, the latest in construction practices and insight on how to market porous pavements.

Understanding the Tier 4 Diesel Requirements: #T15

Tue. March 17 from 7:30 AM - 9:00 AM in Room 308


 This session will begin with a presentation on the background of EPA Tier 4 Diesel Engine regulations development. What does Tier 4 mean? What technologies and approaches have the near zero emissions of Tier 4 Final brought to the diesel engine? What have been the desired goals of the engine development process? Four different equipment manufacturers will each have an opportunity to describe the impact expected for the customer. Finally a panel discussion will open the experts to questions from the audience.

 A well-designed and properly-executed proactive maintenance strategy will enhance the profitability of your Asphalt plant. Proper maintenance of plant equipment can significantly reduce overall operating costs, boost productivity and increase safety. Rather than simply viewing maintenance as an expense, it can actually contribute to profits through performance.  Steve Elam from Stansteel presents this focused perspective called “proactive maintenance” that concentrates on the monitoring and correction of the root causes of equipment failures and implementing thoughtful replacement for improved performance. Extend the useful age of your equipment by mastering operational precision.

Understanding Materials and Plant Operations to Use High RAP Content: #W32

Wed. March 18 from 2:00 PM - 3:30 PM in Room 315


RAP Engineering is a critical part of the asphalt industry's ability to use this important material in asphalt mixes. The RAP must be handled and processed properly and the properties of the mix must be adjusted to account for the presence of the RAP. Plant Operations must be modified in order to accommodate the high percentage of RAP. In this session, Geoff Rowe from Abatech International and TJ Young from the Technical Training and Advisory Services Company will address both the materials and plant handling to achieve high RAP content.
