Wobbly on grooved pavement

It COULD be the alignment. They may have done it wrong, or, more likely, adjusted it into a range that makes the car more sensitive to this. Check the pressures and if that's OK, take it back to the alignment shop and tell them what the car is doing. They may be able to adjust it to the roads you drive and still be in spec.

Do Roads Have Rebar Built Into Them?

Concrete roads have rebar built into them. Rebar provides the road with structural support that reinforces the road. This is an essential aspect of increasing the longevity and durability of concrete roads. Rebar is typically made out of steel or a wire mesh. Keep reading to learn more about rebar, when it is or isn't used in roads, and its ...

5 Reasons Why U.S. Roads are in Bad Shape

Most Interstate Highway roads are built on a thin layer of compacted dirt instead of concrete. So, when the road isn't sealed properly, rainwater gets under the asphalt. It stays in the layer between the asphalt and the foundation. The pressure from cars and trucks pushes the water down and forces some dirt up, creating pockets under the asphalt.

Why are concrete roads better than asphalt? – ProfoundQa

Why do some states use concrete for roads? While many roads and highways use asphalt, approximately 60 percent of the interstate system is concrete, particularly in urban areas. The reason: Concrete is more durable. Concrete supports heavy loads. Concrete experiences less deformation than asphalt in spite of heavy loads.

Do Roads Have Rebar Built Into Them?

Concrete roads built with rebar are used in areas that have a lot of heavy traffic passing by. This is why they are found on highways and interstates and busy roads that regularly have large vehicles traveling over them. Concrete with rebar is also standard in areas with sensitive natural ecosystems nearby.

Why on some roads around town are the bus stops concrete?

Those concrete areas are called concrete pads and they are intentionally left as concrete to maintain a solid, level surface for buses at their stops. Conventional asphalt pavement is flexible and can be moved by the force and heat generated by braking buses. That leads to wave-shaped hills or hummocks along the length of a bus stop.

Why are most runways made of asphalt and not …

The Long and Short of It: Lifespans of Paved Roadways

Highways are typically designed with a "crown," or outward slope of a quarter-inch per foot, to drain rainwater off the road to increase both safety and longevity. Grooves or "tines" cut into concrete and sloped ditches alongside the road also direct water away and prevent damage.

What Are Those Squiggles of Tar on the Road?

Design and construction flaws, such as inadequate drainage for rainfall, or a weak base underneath the road, can also cause the surface to fail. In the arcane, highly technical world of road maintenance, there …

Why does concrete and steel expand when heated?

An average value for the coefficient of thermal expansion of concrete is about 10 millionths per degree Celsius (10×10-6/C), although values ranging from 7 to 12 millionths per degree Celsius have been observed. Why do concrete sidewalks have small cracks between the slabs? Unfortunately, when concrete dries, it shrinks a little bit.

What's Driving You Crazy? Grooves on concrete roads

Concrete, for all practical purposes, is a non-porous substance when it comes to rainstorms, so the groves help disperse some of the rainwater that is on the road and helps it dry out faster. Asphalt, or blacktop, is more porous than concrete and has a higher capacity to absorb water, so there's no need for grooves.

Streetsplainer: What's with those concrete pads in …
