Embodiment Construction

[0043] As seen above, grip level requirements for vehicle and / or tire test tracks are defined eg in standards.

[0044] The method needs to be able to cover 0.5ASTM-16pces The full range of values ​​ASTM-16pces <0.8.

[0045] Various polishing techniques were tested on a track specially built for the study. The various results obtained show that the break-in technique using a surface conditioner equipped with brushes with a greater ASTM The most effective method for the goals required by the level. These analyzes can constitute a double proof:

[0046] i) On the one hand, the technology is able to achieve the target grip within the previously mentioned range;

[0047] ii) On the other hand, a known tire performance test performed on a new track treated with the method according to the invention is capable of yielding tire classification results comparable to those previously obtained on a prescribed or other test track .

[0048] decisive feature

Abstract

A method of abrading the surface state of a test track with a bituminous surface for vehicles is provided. The method includes provision of a processing machine (1) comprising a rotary head (2) with at least one friction element (3) to modify the surface state of the test track; positioning at least one rotary abrasive disk (4) on the processing machine (1); performing movements of the processingmachine on the test track so as to reduce the abrasion coefficient to attain an abrasion level that corresponds to that of an abraded track.

Description

technical field [0001] The present invention relates to a method for grinding in the surface condition of a vehicle test track made of asphalt, the method comprising providing a handler comprising a rotating head supporting at least a friction element for modifying the surface condition of the test track; placing at least one rotating abrasive disc on the conditioner; and treating the surface to be modified. Background technique [0002] In order to improve the quality of roads, road pavement manufacturers are constantly developing new products. Generally speaking, the goal is to increase the durability of the road surface and its mechanical quality in order to obtain better vehicle grip. For this reason, this objective is most commonly used to increase the coefficient of friction of road surfaces. [0003] For their components, builders and suppliers of motor vehicle accessories must be able to test their vehicles and components under the most realistic and repeatable con...
