So, what are roads really made of? The simple answer is that they are made of typicalconstruction materials such as aggregates—soils and rocks—as well asasphalt binderandPortland cement, which act like glue to bond it all together.
1. Polyester fibers are made of polyester as the main raw material, with certain functional masterbatch added. The product density is 136g/cm3. It is soluble in phenol-tetrachloroethane, o-chlorophenol and other solvents. It has very low moisture absorption, acid resistance, high chemical stabilit...
Sand consists primarily of tiny fragments of rocks and minerals, while salt, specifically table salt, is a mineral composed of sodium chloride.
