TxDOT: Working For You - Mill & Inlay on Interstate 20

TxDOT's North Tyler Maintenance and Special Maintenance crews resurface Interstate 20 in Smith County. The process shown here, called "Mill and Inlay," is done in two steps: grinding up the old surface, which is shot into waiting dump trucks, followed by laying down and rolling new hot mix.

what do anntentionuators do? i don't think i spelt it right but its the truck with the stripes on the back.

Attenuators, also called crash attenuators or crash cushions, provide a physical block in the lane closure that in theory prevents motorists from simply driving thru the set-up. The actual attenuator itself is designed to cushion a severe crash from behind (and they DO get hit), thereby saving the lives of the workers present on the job site.

Good question, and thanks for watching!
