City, State Partner on Purchase of Hot Mix for Pothole Patching

INDIANAPOLIS – The Indiana Department of Transportation (INDOT) is partnering with local communities to provide a smoother, more permanent fix to the outbreak of potholes that has resulted from this year’s historic winter. 


INDOT has partnered with the Indianapolis Department of Public Works (DPW) to purchase sufficient quantities for an early reopening of the Rieth Riley hot mix asphalt plant on the city’s southwest side. Deliveries of the hot mix began today. INDOT crews use specialized equipment that will keep the hot mix warm long enough for use in Marion and surrounding counties.

INDOT maintains numbered interstates, U.S. highways and state routes while cities and counties maintain all other local roads. INDOT is actively working with other local communities on bulk purchases that would allow for the early reopening of other hot mix plants around the state.

When water seeps into the cracks of a road and freezes, it expands the layers of pavement, stone and soil beneath the surface. As the ice melts and contracts, heavy highway traffic further loosens the pavement, forming potholes.

When not plowing and treating state highways, INDOT crews are patching potholes in between winter storms. But with more than 30,000 lane miles to maintain across the state, it’s a big job and some crews are working alternating 12-hour shifts to keep up. When Indiana’s hot mix asphalt plants are closed, INDOT uses cold mix – a mixture of small stone and liquid asphalt – as a temporary patch. Even after being filled with cold patch, the same pothole requires ongoing maintenance and can reopen several times throughout the winter.


This winter through Feb. 7, INDOT has devoted 88,000 employee man hours and nearly 7,300 tons of material to pothole repairs and shallow patching, which total to approximately $3.1 million in operational resources. By comparison, the average of the past five state fiscal years through Feb. 7 is estimated at approximately $2.6 million.


For the past several years, INDOT has been expanding its pavement preservation program to improve pavement friction and seal cracks before potholes form. In the fiscal year ending June 2013, INDOT performed crack fill/seal operations on 5,919 lane miles, performed chip seal operations on 1,514 lane miles, and applied a thin overlay surface treatment on 371 lane miles of state highways. For every dollar invested, research estimates that pavement preservation saves taxpayers $6 to $14 in future maintenance and construction costs.


INDOT’s maintenance budget is funded primarily through vehicle registration fees and an 18-cent tax charged for every gallon of gas.



INDOT urges motorists to slow down and stay alert when encountering road maintenance crews. Hoosiers are encouraged to report locations of potholes on Indiana interstates, U.S. highways and state roads by calling 1-866-849-1DOT or visitingwww.potholes.indot.in.gov. Hoosiers may also report potholes on Twitter to @INDOTpotholes.
