Tucson voters passed Prop. 409 in 2012, giving the city about $100 million for road repair over five years. Several neighborhoods have had their streets renovated, using a double chip seal process.
Project manager Austin Wesnitzer said most of the streets that have been redone have been micro milled, scuffing the top layer to remove the high points, then chip sealed with 1/2 inch rock. The roadway is then sealed again with smaller rock, to interlock the two rock sizes and filling most of the cracks in the road.
The final process is a fog seal over the top of the work to seal what cracks were missed by the chip seal.
KGUN 9's Pothole Patrol has received complaints from some of the residents whose streets were sealed, stating that many of the roads are still bumpy.
Wesnitzer said that the scope of the project doesn't allow the money for them to fill all the individual roadway cracks. That's what the chip sealing was meant to do. The timeline for the neighborhood street renovations is tight and will end on June 30th.
The neighborhoods are: Barrio Central, near 22nd & Country Club; El Gecko, near Speedway & Kolb; Poet's Square, near 5th & Columbus and several others near Golf Links, Prudence, Stella, Escalante, 29th St, Sahuara and Wilmot.
