Concrete roads and floors

Concrete road pavement meets such modern challenges as an increase in the number of heavy passenger and freight traffic flows. Higher axial loads, increasing dynamic loads require robust and durable road pavement.

Why concrete?

Concrete is a hard type of coating. Compared to asphalt it’s distributing a load to a larger area, which positively affects the durability compared to asphalt roads. A quality concrete road can serve for a long time without requiring repairs, operating almost without interruption, while on asphalt tracks movement is often limited or stopped because of repair.

According to statistics more than 65% of asphalt roads are suffering from deformation in spring period while for the concrete coverings, this figure is within 5%.

The thickness of concrete pavement is from 6″ to 9″. The road covering is separated by seams every 20-40 ft in the form of slits. The depth of such slots is 1/3 of the slab thickness and they are called false seams. Produced in such a manner seams determine the entire concrete slab behaves. It is absolutely necessary to fill the false seams with the elastic mastics for the reason of compression and expansion. The coating can be made either one or two layered. The upper layer is called the upper concrete, and the lower layer is the lower concrete. Each layer can include one or more layers.

When moving on a concrete road, the quality of the clutch with the surface improves that leads to saving fuel consumption.

Topping

a mixture used to harden the top layer of concrete coating. Other titles: “hardening mixture” or “hardener”

topping

As a hydraulic binder in toppings, as well as in concrete, cement is used, the task of which is to bind and tightly pack fillers.

The functional properties of the topping are determined by the fillers included in it, such as: quartz, corundum materials, metal particles, other fillers – basalt, titanium oxide, silicon carbide, iron carbide and other mineral and synthetic compounds and chemical additives that improve the properties of the material and control the shrinkage processes.

The use of paints allows to apply virtually any color to the tops, which allows them to be used as a decorative floor finish.
