SWCPA Provides Concrete Paving Quality Training

The Southwest Concrete Pavement Association (SWCPA), an ACPA affiliate, along with the FHWA and Caltrans, presented a two-day workshop this week.

The Caltrans/FHWA/Industry Workshop on “Quality in the Concrete Paving Process” is being held today and tomorrow (Feb. 12 – 13) at the Caltrans Southern Regional Lab, Fontana, CA.

Working together with SWCPA Executive Director Charles Stuart, Scott Miller is supporting the event with industry insights and expertise on-site. Scott has also been working to provide information/solutions on sustainability, resilience and recycling. As we reported in November, Charles has been working proactively with the FHWA, Caltrans and industry to provide ongoing training to highway officials.

Workshop Emphasizes QA/QC Roles

The Southwest Concrete Pavement Association (SWCPA), an ACPA affiliate, along with the FHWA and Caltrans, presented a two-day workshop this week to provide concrete pavement QA/QC information to contractors and agency personnel. 

The “Caltrans/FHWA/Industry Workshop: Quality in the Concrete Paving Process,” detailed the benefits of a good QA/QC program and the impacts on longevity of concrete for pavements and other applications. The training emphasized the individual roles among stakeholders and how contractors and agency personnel affect quality, both personally and in a “global” project sense. 

The FHWA Mobile Concrete Technology Center (MCTC) tested concrete on two active paving projects in California and collected data prior to the workshop. The data sets were included in the workshop to further illustrate the role and importance of QA and QC. 

Experts representing the FHWA, Caltrans and the Southwest Chapter provided technical expertise and facilitated discussions and questions & answers. Scott Mueller of ACPA also participated in the workshop in support of the SWCPA. Held in McClellan (near Sacramento), the workshop concentrated on stakeholders in Northern California.

Industry Remembers Caltrans “Trailblazer”

ACPA is mourning the passing of Kirsten Stahl, District Materials Engineer with Caltrans.  She died unexpectedly last week.  

We remember her as someone who was not only well respected by her staff and colleagues, but also by those of us in the industry who worked with her on pavement projects.

Over her career, Kirsten was an energetic participant in several pavement preservation activities of ACPA and IGGA, and was considered among the most open to innovation and embracing new ideas, said Jerry Voigt, ACPA President & CEO. She was involved with pioneering rapid reconstruction and repair techniques for pavements around Los Angeles, where she worked for Caltrans District 7. 

“Her input as an agency representative was always welcome and she was always appreciated for her desire to advance ideas.  She had a very refreshing ‘can do’ nature,” Jerry remembers. 

Jerrel Kam, District 7 Deputy Director for Design said she and a colleague were recently instrumental in trailblazing the use of precast concrete panels, which are now a standard for repairing some of the most heavily trafficked freeways in the nation.

Kirsten came from an important lineage within Caltrans.  Her mother, Marilyn Jorgenson Reece, a Senior Transportation Engineer, was the first female registered engineer in the State of California. Her father Alvin was a Caltrans Transportation Engineer before moving on to the County of Los Angeles, and her late husband Stewart Stahl, was a 40-year Transportation Engineering veteran and well respected designer in Caltrans’ District 7.  Her father-in-law Ernie Stahl also was an Engineering Technician with the Department.

Just a few days removed from celebrating Women in Construction Week, ACPA extends our heartfelt sympathies to those that had to pleasure to know and to work with Kirsten.   We hold up her memory as inspiration to all young women entering or thinking about pursuing a career in a construction field, including in concrete paving.

Funeral arrangements for Kirsten Stahl are as follows: 

Rosary Service: Sunday, March 25, at 7 p.m. (PDT) at Custer/Christiansen Mortuary, 124 S Citrus Ave, Covina, CA 91723.

Funeral Mass: Monday, March 26, at 10 a.m., St. Vincent de Paul Roman Catholic Church, 621 W. Adams Blvd., Los Angeles, CA 90007. 

Lunch Reception:  A reception will follow at Caltrans District 7, at 100 S Main St, Los Angeles, CA 90012.  District 7’s office is about a 10-minute drive from the church.

Committal Service:  Tuesday, March 27th at 11:10 a.m., Riverside National Cemetery, 22495 Van Buren Blvd, Riverside, CA 92518.  Please plan to arrive no later than 11:10 a.m. to Staging Area #7, where cars are lined up to proceed to the grave at the appointed time.  Her service is scheduled to begin promptly at 11:31 a.m. and will be brief, per military procedures in accordance with the cemetery.  Kirsten is being buried next to her beloved husband Stewart who predeceased her in December of 2016.

Memorial Gifts:  In lieu of flowers, the family of Kirsten Stahl have requested gifts in memoriam to Cats in Need of Human Care, an organization of volunteers who work to find forever homes for homeless pets, and also promote spaying/neutering and responsible ownership.  Please follow this link to make a contribution: http://www.catsinneed.com/locations/whittier.

ACPA Presents 2017 Lifetime Pavement Recognition Award

The American Concrete Pavement Association (ACPA) has presented its Lifetime Pavement Recognition Award to a 70-year-old section of concrete pavement on California’s Interstate 10 (Ontario to Colton Freeway). 

The award was presented to the California Department of Transportation (Caltrans) District 8.   Accepting the award on behalf of Caltrans District 8 were Jian (James) Lan, P.E., Senior Transportation Engineer, and Kevin H. Chen, P.E., Transportation Engineer.

The concrete pavement built in 1947 along this 10-mile section, originally designated US 70-99, is still in use today and has survived the unrelenting forces of traffic and time.

In 1967, this pavement became an historic section as the first concrete pavement in the nation to receive a revolutionary new process called diamond-grinding. Today, diamond-grinding is a widely accepted and time-tested technology that is commonly used around the world.

Photo depicts just a few of the agency and industry representatives who have been involved in preservation, outreach, and promotion activities.

Thanks to the innovative and forward-thinking spirit of CALTRANS and the local paving industry, this concrete pavement continues to serve California’s Inland Empire, while linking the past, present, and future of concrete highways.

Awarded annually since 1994, this award is presented to the agency owner of an in-service concrete pavement that has demonstrated exceptional performance and service to its local community, state, and users.  This recognition rotates annually between public market segments: highway, street/road, and airport.
