In this case, one of the key factors is considered to be the finish coat. Before laying this layer, bitumen is applied to the surface of the roadbed. This is a special mixture with a viscous consistency, which is necessary for reliable adhesion of other materials.</p> <p>And at this stage there is an important question - what type of finish coating is better to use. After all, the thickness and technical characteristics will directly affect the appearance, as well as the service life of the road. The higher the quality will be, the more it will be possible to ensure the service of the highway.</p> <p>In fact, in most cases, choose between 2 options. These are cement concrete and asphalt. Each of them has its own features and advantages.</p> <h2>Asphalt</h2> <p>To date, there are several effective ways of laying a coating based on asphalt:</p> <ul> <li>Cold method. It is used only in cases where it is necessary to close large and deep holes, cracks in the road;</li> <li>Hot method. It is used as part of major repairs and is widely used in the construction of new highways;</li> <li>Cast method. A distinctive feature is asphalt with a high level of fluidity. This allows the material to be distributed quickly and efficiently over the entire surface;</li> <li>Colored asphalt. Here, special colorants are used in the composition. The technology is used in areas that should be visually highlighted;</li> <li>Rubber compositions. Additionally, rubber components are added to the asphalt. This affects the cost, but improves the basic performance characteristics of the coating.</li> </ul> <p>Asphalt is used in most cases when solving the tasks of paving roads. Gravel, mineral components, sand, bitumen are added to it. For each situation, the composition and ratio of components is determined individually.</p> <h2>Cement concrete</h2> <p>An alternative for asphalt is a special cement concrete. The material is widely spread in the countries of Europe and the United States. It is characterized by increased strength and durability, which is superior to asphalt.</p> <p>The main area of application is highways with a high level of load. The only disadvantage is the cost. At the same time, the payback of the material is very high, because such a coating will serve for a long time and does not require regular repairs.</p> <p>The properties of cement concrete can cope with the effects of moisture, active temperature fluctuations. Destruction processes are very slow. The surface is not afraid of high pressure and mechanical abrasion. Even under the influence of chemical reagents, the properties and characteristics of the road surface remain unchanged.</p> <p>In the process of road construction, mixtures with special cement in the composition are used. The resulting mixture is poured into a pre-prepared formwork. Also, reinforcing metal mesh is additionally placed inside the cement-concrete mixture. This allows to provide the finished road surface with maximum strength and reliability.</p> <p>Despite the obvious advantages, it is not worth expecting that cement concrete will completely displace asphalt. It is an expensive material, which is not always reasonable to use. Yes, it is an excellent solution for highways and large roadways. But small automobile roads are most often built on the basis of asphalt. This is a cheaper construction technology.</p> <p>It is possible that in the future there will be a worthy alternative, which will not be inferior in strength and durability, but at the same time will not require such high financial investments for the construction of highways. In the meantime, asphalt and cement concrete are successfully used in many countries and have the same high value.</p> </div> </div> </div> </div> </div> </section> </div> </section> </div> </div> </div> <footer class="footer"> <div class="top_button"> <a class="back_to_top"><i class="fa fa-2x fa-angle-double-up"></i></a> </div> <div class="container"> <div class="region region-footer"> <section id="block-block-6" class="block block-block clearfix"> <div style="text-align:center;"> <img alt="logo_footer" src="/hireach.png"> <div> <img src="/images/email-image.png" style="vertical-align:middle"><span style=""></span> </div> <p>漏 HiReach - All Rights Reserved </p> </div> </section> </div> </div> </footer> </div> </div> <div class="page_overlay"></div> <div class="loader"> </div> <script> function euCookieComplianceLoadScripts() {} </script> <script> var eu_cookie_compliance_cookie_name = ""; </script> <script src="/sites/all/themes/bootstrap/js/bootstrap.js?qh3t2o"></script> <script src="/sites/all/modules/eu_cookie_compliance/js/eu_cookie_compliance.js?qh3t2o"></script> </body> </html>
