The grooves or "tining" placed on concrete bridge decks (surfaces) are created for for automobile tire traction when it rains and to help direct the water runoff. Typically the grooves are created in the transverse direction across the direction of automobile travel. More recently longitudinal grooves have gained favor because there is less noise generated when tires follow longitudinal grooves when compared to more noise generated when tires cross transverse grooves.

Why do some concrete-surfaced bridges make high-pitched noises when driven over?
Sometimes concrete bridges are grooved by machine. Bridge decks freeze before roads do because the cold hits both the top and the bottom of a bridge. The grooves increase traction and help prevent sliding when it's snowy or icy. Grooves also lessen the likelihood of hydro-planing. Anyway, the high-pitched noise is caused by the grooves in vehicles tires vibrating against the grooves in the concrete deck.

What is rifling in firearms?
This is a shallow spiral groove cut into the inside of a gun's barrel. As a gun shoots, the projectile engages these grooves and they impart a longitudinal spin to the bullet. This creates gyroscopic stability which greatly increased the accuracy of the projectile.
Do Callaway Diablo Edge irons have square grooves or v grooves?
The original Ping Eye golf clubs had v grooves.
What bridge forms between Calcium ions?
Calcium bridges form between muscle cells. The calcium ions bind to troponin-tropomyosin molecules in the grooves of actin filaments and form crossbridges.
What are some beam bridges?
Most highway bridges and railroad bridges are simple beam bridges. In this type of construction, the road surface or deck is supported by a series of longitudinal beams made of concrete, steel or timber. These in turn rest on bearings, which reston piers or abutments.
Is a sound wave a transverse wave or longitudinal wave?
Sound waves are longitudinal.
What is longitudinal evaluation?
Longitudinal evaluation is a research method that involves tracking the same set of individuals or groups over an extended period to observe changes or outcomes. This method allows researchers to analyze developments, patterns, or trends over time, providing a comprehensive understanding of the subject being studied. Longitudinal evaluations are beneficial for identifying causal relationships and understanding how variables evolve over time.
What causes the grooves in Kelley's Island?
I assume you mean GROOVES - the Glacial Grooves were formed by the receeding glaciers.
Is ultrasound a transverse or longitudinal wave?
Sound, at least in gases like air, can only propagate as a longitudinal wave.
How many grooves are on a quarters edge?
A quarter has 119 grooves, or reeds. The grooves are used as an anti-counterfeiting strategy.
Longitudinal in a sentence?
The study followed a group of individuals over a 10-year period to analyze changes in their cognitive abilities, which is an example of a longitudinal study.
