The Arkansas Highway and Transportation Department has launched a repaving project on a deteriorating section of Interstate 30 in Little Rock.
The Arkansas Democrat-Gazette reports that the work began Friday night and is scheduled to be complete by Tuesday. Traffic will be reduced at times to one lane in each direction on a 3-mile section of the highway. The agency says about 78,000 vehicles use the section daily.
The project will focus on a premature failure of the concrete from a condition which produces a gel that causes cracks or potholes. Researchers believe some concrete projects between 1997 and 2000 are cracking because a mineral in the Arkansas River sand has reacted with high-alkali cement used at that time.
The project is being performed under a $2.1 million contract.
