All CalAPA technical presentations, including a recent one by Dr. Peter Sebaaly of the University of Nevada, Reno Western Regional Superpave Center, are posted on CalAPA's SlideShare page. You can view them HERE.

Sebaaly spoke Sept. 28 about the impact of Warm Mix Asphalt (WMA) admixtures on pavement performance before the CalAPA joint L.A.-San Diego Technical Committee meeting held in Carlsbad.

In addition to presentations from CalAPA's regional technical committee meetings and Contractor Dinners, the CalAPA Slideshare Page stores presentations from all asphalt pavement conferences.

CalAPA would not be able to make such diverse and valuable technical information freely available were it not for the support of its members.

Seats are disappearing faster than a pavement smoothness incentive for the CalAPA Fall Asphalt Pavement Conference & Equipment Expo, to be held Oct. 28-29 in Sacramento. Click HERE to visit the conference website.The premier event brings together hundreds of industry, agency and academia representatives to get the latest information on asphalt pavement design, testing, technology and best practices.

Returning this year is the popular Equipment Expo, where the latest asphalt pavement-related equipment and technology will be on display. A gala reception on Wednesday evening, which is free to all conference registrants, provides a great way to network and view conference displays in a relaxed setting. The location of the conference is the Doubletree Hotel, 2001 Point West Way in Sacramento.

The keynote speaker for the conference will be Steve Takigawa,Caltrans Deputy Director for Maintenance & Operations, who oversees a $2 billion budget, 8,500 employees and a fleet of more than 10,000 pieces of equipment. Takigawa will provide the latest information on the governor's "fix it first" initiative, various sustainability activities and innovations being implemented by the department. Gary Richards, transportation writer for the San Jose Mercury News newspaper, also will be a featured speaker.

Conference presentations will include best practices in Hot Mix Asphalt design; specifications; testing; paving; future trends; research projects and the status of evaluations. There will be in-depth presentations about the new "Superpave" elements being incorporated into Caltrans projects, sustainability, Crumb Rubber Modifiers (CRM), Reclaimed Asphalt Pavements (RAP), Recycled Asphalt Shingles (RAS), binder safety, pavement smoothness and the Material Transfer Vehicle (MTV), the latest advances in visibility during night work, Intelligent Compaction for Cold In-place Recycling and Asphalt Rubber Blending.

There are still a few sponsorship and exhibitor spots open. For more information, click HERE, or contact Sophie You of CalAPA at (916) 791-5044.

PERFORMANCE GRADE (PG) BINDER: A system of categorizing asphalt binders by their physical properties. The PG system uses a common set of tests to measure physical properties of binder that are intended to be related to field performance at extreme temperatures. For example, a binder identified as PG 64-10 must meet performance criteria at an average 7-day maximum pavement design temperature of 64 degrees Celsius and also at a minimum pavement design temperature of minus 10 degrees Celsius.
