Summary
Measuring pavement
Area of Science:
- Pavement engineering
- Transportation engineering
- Environmental science
Background:
- Current methods cannot accurately assess pavement's impact on vehicle energy consumption.
- Reducing traffic-related greenhouse gas emissions requires understanding pavement effects.
- Accurate measurement of rolling resistance is crucial for energy efficiency.
Purpose of the Study:
- To precisely measure the in situ rolling resistance of semi-trailer suspensions on various highway pavement types.
- To investigate the influence of pavement characteristics and tire operating conditions on rolling resistance.
- To provide data for improving road agency initiatives aimed at reducing vehicle energy consumption.
Main Methods:
- Utilized a precise measurement system with embedded transducers to collect data over 174 km of highway.
- Recorded rolling resistance for a semi-trailer suspension under real-world highway conditions.
- Analyzed data considering different pavement types (rigid, flexible, composite) and tire operating conditions.
Main Results:
- Significant variations in rolling resistance were found within pavement types (e.g., 34% for jointed rigid pavements, 21% for flexible pavements).
- Composite pavements generally exhibited higher rolling resistance.
- Rolling resistance decreased by 0.09 kg/tonne for every 1 °C increase in tire temperature.
Conclusions:
- In situ measurement of heavy vehicle rolling resistance (±0.1 kg/tonne) is feasible.
- Pavement characteristics significantly influence rolling resistance, with variations often greater within types than between them.
- Further research under diverse weather conditions is needed to bridge laboratory and real-world findings.

Rolling resistance, also known as rolling friction, is the force that resists the motion of a rolling object, such as a wheel, tire, or ball, when it moves over a surface. It is caused by the deformation of the object and the surface in contact with each other, as well as other factors like internal friction, hysteresis, and energy losses within the materials. Rolling resistance opposes the object's motion, requiring additional energy to overcome it and maintain movement. In practical...

When a solid cylinder rolls steadily on a rigid surface, the normal force applied by the surface on the cylinder is perpendicular to the tangent at the contact point. However, since no materials are entirely rigid, the surface's reaction to the cylinder involves a range of normal pressures.
For instance, imagine a hard cylinder rolling on a comparatively soft surface. The cylinder's weight compresses the surface beneath it. As the cylinder moves, the material in front of it slows down...

01:14Rolling With Slipping
4.8K
Rolling with slipping is a physical phenomenon that occurs when a rolling object experiences both rotational and linear motion but also experiences frictional forces that cause slipping. This phenomenon can occur in various situations, such as when a tire rolls on a wet road or a ball rolls on a rough surface.
An object's rolling motion is characterized by its rotation around its axis, while linear motion refers to the object's translational motion along a surface. Frictional forces can...

People have observed the rolling motion without slipping ever since the invention of the wheel. For example, one can look at the interaction between a car's tires and the surface of the road. If the driver presses the accelerator to the floor so that the tires spin without the car moving forward, there must be kinetic friction between the wheels and the road's surface. If the driver slowly presses the accelerator, causing the car to move forward, the tires roll without slipping. It is...

01:23Abrasion Resistance of Concrete
103
Abrasion resistance is an essential characteristic of concrete that determines its durability and longevity under various wear conditions. Concrete surfaces are vulnerable to different types of abrasion. For instance, surfaces may wear down due to the constant movement of vehicles or be eroded by solids carried in water, as seen in concrete canal linings. Specific tests are conducted to measure the abrasion resistance of concrete.
