Modern roads require improvement in connection with an increase in the geometric progression of vehicles and laying new communication paintings. The material used in the construction of such roads should be durable and durable, as well as capable of transferring all the effects of atmospheric phenomena that occur in nature. Road workers must take care of the throughput of the tracks. For aerodrome sites, according to international standards, a high degree of fortress is provided, since transport with a huge toning is moving along them.
Ideal characteristics that roads and airfield roads should have are recently acquired by road slabs. This is a demanded and at the same time high -quality industrial product – auto -banks and automobile highways, of course, are laid not for one or two years, but so that a large number of vehicles can pass through them over many years. Roaders will not repair road networks using reinforced concrete slabs as often as, say, asphalt roads.
Road slabs are concrete structures. For their production, not a conventional substance is used, but a “heavy” concrete. Sometimes reinforcement with voltage is added to production technology. Permissible load for road plates-N-10 and N-30. The chip of road slabs in their long -term operation, technical characteristics and strong properties that are not lost even in the forty -degree frost. In addition, road slabs can be produced in different combinations and forms, which contributes to the implementation of the most crazy engineering and construction projects.
Plates for roads and airfield roads are completely different construction products. Their difference lies in the mass. So, for example, the weight of the road slab for an autobahn is 2.2 tons. The mass of the plate used in laying the airfield highway will reach 5 tons.
Road plates in the technical literature even have their own classification. There are such types of plates: PDS, PDN, PAG-14, PAG-18, PD, PDP and T. D. They vary in length, height, width, diameter and purpose. In particular, an airfield plate of the PAG-14 type six meters long and about 4 tons will weigh two meters wide. This is an average indicator.
When laying roads and airfield roads using reinforced concrete plates, it is important to consider the features of the surface layer of the earth. Even the smallest soil shifts can lead to the fact that the roadway will need major repairs. Under the conditions of movement of the earth’s surface, public utilities will have to also be a question with the seams that may disperse.
