Transportation Defined

Mechanically Stabilized Earth walls are all around you ... if you know where to look.

Today we are taking a look at batch plants and how they help projects be more efficient and cost effective.

Today's Transportation Defined is all about pavement preservation. Let's talk about fog sealing.

For chip seal work, like what our crews just completed on State Route 88, a tack coat is the glue that holds it all together.

When motorists enjoy a wider I-10 in Casa Grande beginning next year, it'll be thanks in part to piers and pier caps supporting an expanded bridge at Jimmie Kerr Boulevard.

Rustication and graphic elements are used to help create visual interest and a sense of place.

If you’ve driven recently on the Loop 202 Red Mountain Freeway, you might recognize the structure pictured in today's post.

Dirt has been a pretty popular topic for us. Today, we want to explain why we bench it. More specifically, why we minibench it.

When someone hears the word “asphalt,” they might picture the road that they drive on, but asphalt is actually one component of that surface.

While their name might sound somewhat morbid, Deadman Anchors are actually nothing to be afraid of. In fact, they’re very handy on a project site.

We have a couple of new terms for you today and they both have to do with concrete.

Crews recently removed lead paint from the 100-year-old Chevelon Creek Bridge near Winslow.

You know that there are layers of dirt and rock lie beneath the surface you drive on, but would you guess that some roads are built on top of a special material (in addition to all the dirt and rocks)?

If you’ve ever drifted a little too far outside a travel lane, only to be jolted back to attention with a not-so-subtle shake, you know what rumble strips are.

No, this photo isn’t an example of ADOT’s latest design “statement.” Despite how it might look, the cement is not being painted a pale pink hue.

No, the stair-step design on the slope at right isn’t just for looks… The “steps” are actually referred to as minibenches and they serve as an erosion and sediment control measure on slopes.

You’ve likely recycled plastic, glass, paper, maybe even your old electronics, but did you know ADOT recycles its old asphalt pavement?

You might remember that we blogged about inclinometers back in February – they’re the instruments used to measure slope inclination or movement at specific locations ...

Unless you drive a big rig, truck escape ramps probably aren’t something you think of too often ...

After 300-plus blog posts, you’d think that by now we’d have covered everything there possibly is to know about pavement ... But you'd be wrong.
