Mastic asphalt is a type of asphalt that differs from dense graded asphalt (asphalt concrete) in that it has a higher asphalt content, usually around 7-10% of the whole aggregate mix, as opposed to rolled asphalt concrete, which has only around 5% asphalt. This thermoplastic substance is widely used in the building industry for waterproofing ...

These are important for the asphalt to be properly controlled, transported and used in paving projects. Cold-mix asphalt is made of quarter inch chip and proprietary oil. This specific make-up keeps the asphalt soft and helps it repel water. As its name suggests, cold-mix asphalt does not need to be warm to be used in asphalt repair.

How asphalt cement is made - material, used, processing ...
2 Asphalt may next be blended or "cut back" with a volatile substance, resulting in a product that is soft and workable at a lower temperature than pure asphalt cement. When the cut-back asphalt is used for paving or construction, the volatile element evaporates when exposed to air or heat, leaving the hard asphalt cement.

asphalt concrete are evaluated for compliance to the mix design parameters and to the specifications - gradation, oil content, sand equivalent, stability and voids. The production start up evaluation is conducted using aggregate taken from the production process and asphalt concrete taken from the material placed behind the paver.
