Optimizing Concrete Pavement Opening to Traffic


Recent research has determined that conventional wisdom of designing concrete mixes for very high early strengths to open the pavement to traffic early may not be the best approach. Typically, high early strength mixes contain additional cement in order to obtain design strength faster, but end up with a 28 day strength much higher than design. This additional cement not only increases initial cost but more importantly, may reduce long term durability. The Concrete Pavement Technology Center recently published a technical summary entitled ‘Optimizing Concrete Pavement Opening to Traffic’ which examines these considerations and suggests that a much better approach may be to redefine our opening to traffic strengths to something much lower than what we are using today.

Joe Echelle Recognized as Government Official of the Year by International Grooving & Grinding Association

Joe Echelle, Oklahoma Turnpike Authority, receives the 2022 Government Official of the Year Award

The 2022 Government Official of the Year award went to Joe Echelle, Assistant Executive Director, Maintenance, Engineering & Construction, Oklahoma Turnpike Authority (OTA). The Government Official of the Year award recognizes leadership in transportation with special emphasis on grooving, grinding and concrete pavement preservation (CPP).

In his role with the OTA, Echelle is responsible for maintaining 630 miles of turnpikes throughout Oklahoma and is responsible for day-to-day operations. He was chosen to receive the Government Official of the Year Award because he has been a continuous champion of improving pavement conditions, making them more safe and efficient for Oklahoma motorists. His approach of maintaining pavements before they deteriorate, rather than addressing problems when the pavements are already at the end of their life, has resulted in millions in dollars of savings for Oklahoma residents.

“Joe has been an exceptional advocate for concrete pavements as well as the importance of pavement preservation techniques to optimize the taxpayer’s investment. We are thrilled to see his efforts recognized on a national level as the way DOT leaders can and should approach highway maintenance.” said Brent Burwell, Executive Director of the Oklahoma/Arkansas ACPA Chapter.

ARDOT Announces New Work Zone Safety Campaign

The Arkansas Department of Transportation (ARDOT), together with Arkansas State Police (ASP) and Arkansas Highway Police (AHP), announced today a new work zone safety campaign aimed at cracking down on reckless and distracted driving in work zones across the state. 

The Slow Down, Phone Down campaign will deploy increased ASP and AHP patrols in work zones to watch for dangerous driving. The goal is to eliminate preventable accidents.
 


In 2021, there were 2,140 crashes reported in Arkansas work zones – resulting in 16 fatalities and 54 serious injuries. 

“The number of work zone accidents and injuries is rising at an alarming rate in Arkansas,” said ARDOT Director Lorie Tudor. “Even one injury in a work zone is one too many. We can all do our part to reverse this trend.” 

ASP and AHP will be issuing citations to motorists observed using their phone, following too close, or speeding through a work zone – all of which are illegal in Arkansas.   

“As crews go about their jobs improving Arkansas highways, they deserve our best attempts to make their work environment as safe as possible,” said ASP Director Colonel Bill Bryant. “State Troopers will be lending support to the Arkansas Highway Police in their effort to stop motorists who ignore the rules of the road and endanger the lives of those working to make our highways better and safer.”         

“It’s our duty to protect work zones, the men and women working within them, and the citizens driving through them,” said AHP Chief Jeff Holmes.  “We have zero tolerance for distracted and reckless driving. We hope this campaign makes it clear that we need people to slow down and put their phone down when entering a work zone.” 

The Slow Down, Phone Down campaign will take place statewide and will target all motorists – including both commercial trucks and civilian vehicles. For more information, please visit: https://www.ardot.gov/slowdownphonedown/

Concrete Pavement Preservation Key to Extending Life of Oklahoma’s Turnpike System
