What are the causes of road deterioration?
cars driving on the roads, weathering,car accidents, crazy builders with hammers, tempreature change causing cracks
What does chaussée mean in English?
Chaussée (from the verb chausser / être chaussé) means to wear a shoe. (shoe is 'chaussure' in French) Chaussée (feminine noun) means 'carriageway' (technically the part of the road designed for cars, excluding gutters, road embankments, shoulders, etc..)
Why clay soil is not recommended to be used as road embankment but it is suitable for use as base and fill material in earth dam construction?
as clay has more porosity as it absobs water may causes damage to the construction
When highway engineers build road in a mountainous area they inserted drainage pipes into the slopes alongside the road-why?
The drainage pipes are to prevent the road surface cracking by keeping the ground near the road dry. When the ground underneath the road gets wet, the road could sink, kind of like when you walk in a swamp. If only part of the road sinks and the rest stays in the same place, the road could crack where the sunken portion of the road meets the part that hasn't sunk.
Use ideas about forces and energy to explain how these advance help road safety?
they use crash barriers, barrels of sand or water, and road surface technology. the crash barriers 'flex' so when a car crashes into them, less damage is done. barrels of sand or water save a car crashing into a sheet of concrete or metal sheets, also less damage is done to car an less chance of serious injuries. with road surface technology such as, red tarmac- this is used to caue more friction between the tyre and the road. this causes the car to go at a slower pace, these are mainly used at pedestrian crossing, school crossings, traffic lights and turning a corner.
What causes the tide rod end to go bad?
The ball joint in the tie rod end can wear out due to normal wear and tear from driving, road conditions, and lack of lubrication. Other causes can include excessive vibration, contamination from debris in the road, or damage from a collision.
What are the most common causes of road bike crashes and how can they be prevented?
The most common causes of road bike crashes include distracted riding, failure to obey traffic laws, poor road conditions, and lack of visibility. To prevent crashes, cyclists should stay focused, follow traffic rules, maintain their bikes, wear bright clothing, use lights, and communicate with other road users.
Why friction cause tread on tire wear down?
Friction between the tire and the road surface generates heat and causes wear on the tire tread. As tires grip the road during acceleration, braking, and turning, the rubber compounds in the tread gradually wear away. The constant contact and movement lead to the loss of material over time, resulting in reduced tread depth and performance. This wear can be exacerbated by factors such as driving habits, road conditions, and tire maintenance.
What is one way friction affects a car?
Creates heat in the engine (friction of moving parts creates heat) Reduces efficiency (friction in the drivetrain, as well as air resistance, slows the car down) Causes the tires to wear out (friction between the road and the rubber causes the rubber to wear)
What form of energy causes cracks in roads?
Thermal energy from the sun causes roads to expand and contract, leading to stress on the road surface. This stress, combined with regular wear and tear from vehicles, can eventually cause cracks to form in roads.
Do the New York Yankees ever wear the blue road shirts at home?
The Yankees do not even have blue road shirts (their road uniforms are gray) and they never wear any part of their road uniforms at home.
What color jackets do road workers wear?

What are the bad effects of road salt?
Road salt causes corosion of vehicles
What are the causes of road accidents in South Africa?
Causes of accidents in south africa.
What are the most common causes of road accidents?
The most common causes of road accidents are errors by the driver, bad or poor weather conditions, a distraction, road design and problems or defects with the vehicles.
What causes tappets to make noise?
Excessive wear, or lack of oil. Or both. Generally lack of oil is what causes the excessive wear.
What causes choppy tire wear on the inside edge of the tire?
Uneven tire wear with spots is usually caused by bad shock absorbers or struts. If the car or truck bounces too much while driving down the road it makes bald spots on the tires.
