Asphalt called as blacktop, macadam or tarmac is particular product, used in industry such as asphalt pavement, where it is often referred to as asphalt concrete or hot-mix asphalt. Asphalt plant equipment is used for the manufacture of asphalt or other forms of coated roadstone, which is usually called asphalt facilities in the asphalt pavement industry, because these are mixing facilities.
Asphalt pavements are smooth, cost-effective to construct and maintain exceptionally durable, environmentally friendly and 100 percent recyclable, as a result, in nowadays, most of our streets and highways are surfaced with asphalt. Asphalt concrete plants are placed next to homes, businesses and farms.
Asphalt paving mix sounds complicated but it’s really simple with two basic ingredients, one is aggregates such as crushed stone, gravel and sand, but what being used are mostly locally available stone. The aggregates take up 95 percent of the total weight of an asphalt pavement.
The other one that takes up 5 percent is asphalt cement, which acts as the glue to hold the pavement together and sometimes is called binder or bitumen. It is a petroleum product generally obtained from the same refineries that produce gasoline for the car or heating oil for the house. Different types of pavements need different standards asphalt cement as one of the heaviest, most viscous parts of petroleum.
Sometimes, a small amounts of additives, ranging from chemicals that improve mix performance to natural fibers that strength specialty mixes, are required.
Sometimes, portable asphalt plant are nice choice under the following condition. Mix aggregates, asphalt cement and sometimes additives together, you will get asphalt paving mix. While these materials have to be carefully monitored and regulated. Inside the asphalt plant, the aggregates are dried and heated, then mixed and coated with asphalt cement. The resulting asphalt pavement mix is put in silos for short-term storage, then trucked to the paving site.
The temperatures of mixing asphalt pavement mixtures are usually between 300°F and 325°F, and it has to be laid hot, no less than about 250°F. When getting HMA from the facility to the paving site, the speed must be fast, as the farther you have to carry it, the cooler it gets, and if it gets too cool, it is no longer useful for paving. Bitumen hot mix plant is adopted by the pavement industry to make the asphalt paving mixes be created and used at lower temperatures without sacrificing quality.
Asphalt plant is playing a critical role in building and maintaining the nation’s infrastructure, in order to meet the requirement of different types of pavements, we need more modern asphalt plants. China asphalt batch mix plant manufacturers are good choice nowadays.
