Rapid Development of Highway Transportation in China,Further improvement of driving comfort and safety has become an important part of the development of industry technology.。

When the vehicle is braked, especially in the case of emergency braking when driving on a curve or slope.,Often because of the effect of the moment of deflection,Resulting in lateral slip of the vehicle body,It even causes incalculable serious traffic accidents.。

Nowadays, most high-grade roads are asphalt concrete pavement.,The skid resistance of this type of pavement mainly depends on the depth of pavement structure.。It is obvious that the frictional resistance of this common type of road surface is the same in all directions.,Lack of restraint on vehicle sideslip。However, excessive increase in the depth of pavement structure will affect the compactness and waterproofness of the pavement.,At the same time, increase the driving noise.。



 

 

In order to effectively solve the problem of driving safety caused by insufficient skid resistance of pavement,,At the same time, it takes into account the noise reduction and compactness and waterproofness of the pavement.,National Engineering Research Center for Highway Maintenance Equipment,Research and development “Large-texture skid-resistant pavement”( Large textured Anti-slip Surface)New technology,Hereinafter referred to asLASRoad surface

 

 

LASThe pavement surface is transversely corrugated.,Its structural depth is much greater than that of conventional asphalt concrete pavement.,And has clear directionality.。

 

The results of pavement skid resistance test show that:


 

1

LASThe friction coefficient of the pavement in the driving direction is greater than that of the conventional asphalt concrete pavement.;

2

LAS The transverse friction coefficient of the road surface can reach 1% of the friction coefficient in the driving direction.5x;

3

According to the law of friction,LASThe road surface has good guidance for running vehicles.,Instinctive resistance to yaw sliding,The driving safety can be effectively improved.。

 

 

LASThe construction depth of the pavement is not dependent on the large aggregate,Therefore, it can be considered that the vehicle is running on a flat road surface with strip positive texture in the same direction.,Not easy to generate impact noise。At the same time, the negative texture of the pavement runs through from front to back.,No negative pressure explosive sound will be formed between the tire and the road surface.,TestedLASRoad surface can reduce noise 2—Three decibels,This is more important for non-open space such as tunnels.。

 

LASThe road surface can improve the road surface night vision effect,First,This kind of longitudinal stripe pavement has good visual guidance.。In addition,The diffuse reflection of striped pavement can effectively reduce the dazzling and tension caused by strong light.。

 

About LASThe road surface can be consulted by contacting the New Technology Demonstration Center.(0373-5068635),The demonstration center will provide the most effective service and treatment technology according to the needs of users.。
