Asphalt profiling is the most popular method used to cover roads and sidewalks. The demand for the material is due to its unique physical and chemical properties. Properly laid asphalt, subject to the technology of laying asphalt is resistant to adverse climatic factors, characterized by wear resistance and long service life. Below are some of the asphalt laying techniques that are commonly used.
Cold asphalting:
During cold asphalting, the basis of the mixture is liquid oil road bitumens. The peculiarity of the work- laying is possible only in the warm season. This results from the fact that the stage of water drying is not applied. This method of asphalting is well suited for patching.
Hot asphalting:
During hot asphalting, the main components of the mixture are liquid and viscous oil bitumens. The work can be carried out during winter times, that is when it is cold. For the asphalt surface to be durable, the temperature of the asphalt when laying must be at least 120 degrees. The place to lay asphalt is pre-dried using special equipment.
The stages involved in successful asphalt profiling:
Asphalt profiling at all times has to follow various stages before applying the sealants. They include;
1. Developing Design Estimates: The project should be developed, taking into account the features of the site, which has its characteristics (topography, parameters, soil structure). After the specialist’s calculations, an estimate is made, which takes into account; the plot size, volume of work, and preliminary cost.
2. Begin Preparatory Work: The top layer of the soil should be removed for the process to work great. If the task is to remove a large layer, the use of specialized equipment such as bulldozers and loaders is required. The territory is levelled by the graders. The project should be designed so that rainwater flows into the drainage system and does not accumulate on or under the asphalt pavement.
3. Preparing the Base: At this stage of asphalt profiling, laying of sand or gravel-sand mixture is done, then the top of the coating is sprinkled with large fraction gravel. Each layer must be levelled with the help of a grader and carefully tamped so that the coat doesn’t lose its quality. The side stone is used for enclosing an asphalted area. Also, the surface should be soaked with bitumen before asphalting.
4. Laying of the Asphalt: This is the final stage in profiling. If the material is not prepared directly on site, the delivery is carried out using dump trucks. Sand, mineral powder, liquid bitumen, and crushed stone are the critical components of the asphalt concrete mix.
When applying the mixture, it is vital that it be evenly applied. To avoid irregularities, resort to the help of asphalt pavers to help you with asphalt profiling process. To increase the density of the coating, the installation is carried out using several rollers. The use of technology in profiling that is specifically designed for each type of work is recommended. Only in this case, the coating will be of high quality.
To properly lay the asphalt and give it strength and durability, you must carefully follow all the stages of the asphalt profiling and apply specialized equipment. Only a heavy machine can well tamp the layers of asphalt concrete pavement to minimize voids and ensure high density to the canvas. High-quality, step-by-step execution of all works ensures high operational properties of the coating and long service life.
