Click now to dive into the definitive tutorial on selecting the right heavy equipment to build the roads of tomorrow, today.
With the growing requirements across the globe in regard to durability, sustainability and efficiency, contractors in the construction field and government bodies should embrace modernized machinery in order to cope. To deliver a strong road, one needs not only aggregate and binder, but exact engineering equipment manufactured with unique purposes in mind, including mixing raw materials and high-speed preventive maintenance.
In this tutorial, we have explored the essence technologies that form the foundation of contemporary road construction with regard to three major classes of equipments that the leading industry conglomerates offer: asphalt mixing, bitumen processing, and high precision pavement repair. The key to providing strong, durable roads that are resistant to time and traffic is first knowing what these advanced machines are and how they are used.
Hot mix asphalt (HMA) is the lifeblood of most of the modern roads and the asphalt mixing plant strictly controls the production of this material. These plants are in essence advanced industrial plants that are able to carefully combine, heat and blend bitumen with different aggregates according to certain, predetermined recipes. The long term performance of the pavement depends on the quality and consistency of the HMA.
There are three main categories of asphalt plants that are available in the industry depending on the size of the project and the mobility needs:
(1) Stationary Asphalt Batching Plants: They are suitable to large scale projects with extended lifespan such as a major highway or airport runway. They show unmatched accuracy of mixing and high output capacity so that the HMA quality remains intact. Specific, customized mix designs can be done using the batching process and therefore they are used in the most demanding specifications.
(2)Mobile Asphalt Batching Plants: A perfect combination of both high capacity and required portability. These plants can be dismantled and re-built within a short period of time and they can also be transported and re-assembled near the construction site. This radically saves transportation expenses and most importantly, minimizes the cooling time of HMA in transit which is critical in attaining optimum pavement compaction as well as quality.
(3)Continuous Asphalt Mixing Plants: These are plants that are used when continuous production is needed and used where continuous, steady HMA production is required, as in continuous paving projects. They simplify the mix up and this results in high productivity with less complication during operations and a steady stream of output.
The new generations of these plants have energy efficient burners and have advanced dust collection systems, thus reflecting the commitment to performance as well as being environmentally compliant, and are therefore necessary and smarter investments towards future proofing of the infrastructural development.
The sticky black material, which is bitumen (or asphalt cement), must be prepared before the sticky material can be mixed or sprayed. It is at this point that specialized bitumen processing equipment is involved that will transform the solid or low melting point bitumen material into a useful form of liquid that can be used in road construction projects.
(1)Bitumen Melting Machines (Barrels and Jumbo Bags): Bitumen is transported and stored in solid state in a variety of regions in standard steel barrels or giant cost-effective Jumbo Bags (usually 1 to 2 cubic meters in weight). To effectively and efficiently melt the solid bitumen into a liquid state to be used in the mixing plant or distributor, high-capacity melting machines are used, and stirring may be based on the heating media of hot thermal oil or direct gas heating. A dedicated melting system minimizes the amount of material wastage significantly and guarantees that the bitumen is heated to the proper temperature and not degraded or overheated in a localized place.
(2)Emulsion Bitumen Plants: These are advanced facilities which are central to the construction of sustainable roads. Bitumen emulsion is a homogenous mass of bitumen and water, which is bound by an emulsifier. It is very advantageous to use emulsion in road works since it can be used at cold or warm temperatures, which save much energy and prevent air pollution as there is no need to heat the binder to very high temperatures. It finds extensive application in surface treatments, prime coats, and tack coats.
(3)Polymer Modified Bitumen (PMB) Plants: Modified bitumen is needed in roads that have to withstand heavy traffic loads, extreme temperatures, or other causes of great structural stress. PMB plants are used to add polymers into the bitumen in controlled shearing process to increase its elasticity, cohesive strength and universal durability to a great extent. PMB is a critical component in demanding applications such as airport runways and high volume expressways, which directly increases the service life of the road and also reduces significantly lifetime maintenance costs.
Constructing a road is one thing but keeping it productive and proactively is the most important thing in ensuring that the targeted lifespan of the road is realized. The current road maintenance machinery employs accuracy technology to ensure that minor faults do not develop to costly structural defects.
Although asphalt is used on major roads, concrete cannot be ignored in buildings, foundations and heavy pavements that have heavy loads. Comprehensive infrastructure solution providers should also be able to provide variety of concrete machinery which is reliable to support comprehensive execution of projects.
The future of infrastructure development and road construction is not doing it at a faster rate but doing it better. This has been done through incorporation of SINOTO high-quality and specialized machinery at each stage of a project.
With the help of the high-quality material produced using modern asphalt mixers, the optimization of the binders produced with the help of efficient bitumen processors, and the correct maintenance vehicles such as the synchronous chip sealer or slurry paver, the construction groups can make the quality of their work high, reduce the cost of operation to the minimum, and finally, create the real transport network of the world.
The most effective promise of infrastructure long life is the investment made in the appropriate technology.
