Surface Properties of Roads.

The meeting took place in full -time form in Prague at the headquarters of the Czech Road Society Z.S.
It was attended by 17 persons, mostly members of this section.

At:https://www.povrchove-vlastnosti-vozovek.cz/New websites have been published to measure and evaluate the surface characteristics of the roads.

These websites were created in connection with activities dealing with the staff of the Transport Research Center, v. I. and other members of the Czech Road Society - Surface properties of roads, especially L. Nekula, P. Nekulová, J. Sláma and České Kopřiva.

The pages are divided according to the following variables of road surface parameters:

• the texture of the surface,
• the anti -skid properties of the surface,
• the noise of the surface,
• the unevenness of the surface.

In particular, you will find here:

• Information on measuring devices and methods,
• Overview of current standards, technical regulations, methodologies, etc.,
• the usual life of the road surfaces in terms of selected parameters,
• Links to other sources of information,
• News on this topic.

Information from the new methodology is also published here: the principles for the use of abrasive layers and technologies of maintenance and repair of road surfaces in terms of anti -German properties, which is free to download at:https://www.shopcdv.cz/cs/metodika-protismykove-vlastnosti.

The meeting took place in full -time form in Prague on Novotný footbridge 200/5.

It was attended by 20 people, mostly members of this section.
