Overview
* Asphalt : the product of oil-refining industry; the natural state is hot condensed, black
* Usage: The material in production of asphalt concrete which is used in the construction of roads, airports, stations, and others.
* Classification of asphalt:
- Hot hot condensed asphalt: heated in the temperature of 120oC to 145oC, transported in liquid form.
- Hot condensed asphalt: stored in barrels, in polymer packages at environment temperature. For usage, it must be heated to the melting point so as to turn into liquid form, then taken off the barrels and moved to asphalt concrete mixer station.
MC asphalt, emulsion asphalt, polymer asphalt,…: are the products
of asphalt in liquid form, contained in barrels or transported by tankers, ISO tank.
For hot hot condensed asphalt, in liquid form:
Liquid asphalt is preserved in the temperature of 120oC to 145oC . Hot hot condensed
asphalt, in liquid form at 120oC to 145oC is preserved during the storing process in
warehouse and transported by tankers to mixer stations.
- Barrel-stored asphalt is packaged directly from hot hot condensed asphalt, in liquid
form, and cooled to environment temperature. These barrels are stored in warehouse.
- Products from MC asphalt: directly produced, made up in asphalt warehouse and sold
by two ways: transporting by tankers (liquid), and packaging in 200 liter steel barrels.
- Products from CRS emulsion asphalt consumed domestically are mostly imported from abroad.
