How Many Days is the Maintenance Period for Asphalt Pavement?

Asphalt concrete pavement surface does not require curing. Generally, traffic can be opened once the surface temperature drops below 60 degrees after compaction. Below is relevant information on asphalt pavement maintenance: 1. Maintenance precautions: While ensuring the original pavement structure standards, maintain the original structural strength. Asphalt pavement needs frequent removal of debris such as soil, stones, and gravel, especially at junctions with other types of pavement, where cleaning should be intensified. Mixing mortar or concrete on the pavement is prohibited to avoid contamination, which can lead to uneven surfaces or reduced skid resistance, adversely affecting traffic. 2. The optimal timing and cycle for preventive maintenance of municipal roads: The first stage is the initial usage phase after construction, during which the asphalt continuously oxidizes or wears over time; the second stage occurs after the asphalt road has been in use for some time, showing minor cracks or slight potholes; the third stage, building on the second, sees further development of defects leading to aggravated pavement damage, with large-scale cracks, even cracking and subsidence, rendering the road impassable for normal vehicle traffic.

What is the normal tire pressure range for the Emgrand GS?

The normal tire pressure range for the Geely Emgrand GS is 2.4-2.5bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2bar in winter and decreased by 0.1bar in summer. This data is based on the international GBT2978-2008 standard. The Geely Emgrand GS is equipped with an active tire pressure monitoring system (TPMS), which automatically monitors tire pressure while driving. However, it does not display the specific pressure or temperature values for each tire, only the TPMS warning symbol and the abnormal tire pressure warning symbol. When tire pressure is abnormal, the tire pressure warning light in the Emgrand GS will illuminate. Generally, a tire pressure above 2.8bar is considered too high, while a tire pressure below 2.0bar is considered too low. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; causing steering wheel vibration and deviation, reducing driving comfort; accelerating wear on the central tread pattern, shortening tire lifespan; increased body vibration, indirectly affecting the lifespan of other components; excessive stretching of tire cords, reducing tire elasticity and increasing the load on the vehicle while driving. Hazards of underinflated tires: Increased friction coefficient with the road surface, leading to higher fuel consumption; causing heavy steering and deviation, which are unfavorable for driving safety; increased movement of tire parts, leading to abnormal overheating due to excessive rolling; reduced functionality of cords and rubber, causing delamination or cord breakage and excessive friction with the rim, damaging the bead area and causing abnormal wear; multiplied friction between the tire and the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to a tire blowout. If the tire pressure monitoring indicator light (a yellow symbol with an irregular circle, no stamp on top, four small spikes at the bottom, and an exclamation mark inside) illuminates, there are generally three possible reasons: Abnormal tire pressure: Typically, the system will alert if the pressure is below 1.8bar or above 3.0bar. In this case, tire inspection and pressure adjustment are necessary. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the system will still record the previous data, causing the tire pressure monitoring light to illuminate. Simply reset the tire pressure to resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is installed inside the tire and connected to the inflation valve. If the sensor is damaged due to impact while driving, the tire pressure warning light will illuminate. For sensor damage, the only solution is to replace it with a new part.

Should You Use Internal or External Air Circulation When There's an Odor in the Car?

Use external air circulation. The differences between internal and external air circulation are as follows: 1. Different working principles: Internal circulation means the air inside the car is heated or cooled and then recirculated within the vehicle; external circulation involves drawing in outside air, heating or cooling it, and then sending it into the car, effectively exchanging air between the inside and outside of the vehicle. 2. Different usage methods: When turning on the air conditioning for cooling or heating, you can first activate internal circulation to quickly lower or raise the temperature inside the car. Once the temperature stabilizes, appropriately switch to external circulation to exchange air with the outside. If the outside air quality is poor, such as in heavy traffic with lots of exhaust fumes or in underground parking lots, avoid using external circulation. When driving on the highway, never open the windows; instead, use external circulation. If you feel stuffy inside the car when the outside air is good, switch to external circulation for ventilation.

How Many Days Does It Take for Car Window Tinting to Dry in Winter?

Winter temperatures are relatively low, requiring 7-14 days for the window tinting to fully dry. During the 7-14 days after tinting in winter, do not roll the windows up or down to avoid peeling the edges when operating the windows. Below are precautions and identification methods for car window tinting: Precautions for car window tinting: When getting car window tinting, it is necessary to inspect the workshop. Car window tinting should be done in a fully enclosed dust-free tinting workshop. During the tinting process, there should be no floating dust in the air. Also, observe whether the tinting workshop has spray dust suppression facilities, which can provide a better environment for car window tinting. The tinting workshop should be equipped with a humidifier to ensure the tinting environment. Identification of car window tinting: Make a general judgment of the car window tinting by its color. Generally, high-quality car window tinting uses lighter colors that are comfortable for the eyes, such as light green, sky blue, gray, brown, and natural colors. The tinting color should not fade.

Is a Speedometer Marked 260 Indicative of a Good Car?

Is a Speedometer Marked 260 Indicative of a Good Car? For example, the speedometer of a Mercedes-Benz A-Class car is marked up to 260 mph. Here is some related information about car speedometers: 1. Car Speedometer: The maximum scale on a car speedometer is called the "speedometer bottom." Generally, the maximum speed indicated on a car speedometer is the highest possible speed under the engine's no-load maximum RPM. Therefore, cars with higher speedometer bottom values usually have better performance. 2. Working Principle: The speedometer's indication relies on a speed sensor, which is installed on the transmission. Different rotation speeds generate different pulse signals, which are then converted into pointer output to display the current speed. Regulations require that the speedometer display a slightly higher speed than the actual speed for safety reasons. Another type is the LCD speed display, which works on a similar principle, except the output is displayed on an LCD screen instead of a pointer.

What are the regulations for motorcycle cargo?

Here are the legal provisions for motorcycle cargo: 1. Article 55 of the 'Regulations for the Implementation of the Road Traffic Safety Law': Mopeds are not allowed to carry passengers, and ordinary motorcycles are not allowed to carry minors under the age of 12 on the rear seat. Passengers are not allowed on the rear seat on highways. The cargo on a motorcycle must not extend more than 15 centimeters beyond the handlebars on either side, and the height must not exceed 1.5 meters from the ground. 2. Article 54 of the 'Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China': The cargo carried by a motor vehicle must not exceed the load capacity specified on the vehicle's license. The length and width of the cargo must not exceed the dimensions of the vehicle body. The third provision states: The height of cargo on a motorcycle must not exceed 1.5 meters from the ground, and the length must not exceed 0.2 meters beyond the body of the motorcycle. For two-wheeled motorcycles, the width of the cargo must not extend more than 0.15 meters beyond the handlebars on either side; for three-wheeled motorcycles, the width of the cargo must not exceed the width of the body.
