A pothole is a structural failure in a road surface, usually asphalt pavement, due to water in the underlying soil structure and traffic passing over the affected area. Water first weakens the underlying soil; traffic then fatigues and breaks the poorly supported asphalt surface in the affected area. Continued traffic action ejects both asphalt and the …

The specific gravity of all other materials are compared to water as a fraction heavier or fraction lighter density, no matter how small or large the fraction is. For example, ammonium nitrate has a specific gravity (sg) of 0.73 while dry ammonium sulphate has a sg of 1.13 (1130 kilograms/cubic meter).

The weight of a batch of concrete varies with its composition, but a typical concrete mix about 145 pounds per cubic foot (pcf). Specific gravity is the ratio of the weight of a cubic foot of a material to the weight of a cubic foot of water, which is 62.4 pcf. Therefore, the specific gravity of a typical concrete mix is 145/62.4 or 2.32.
But it only works on asphalt roads. The second solution—which Zanko calls Rapid Patch—works on both concrete and asphalt. It’s a water-activated magnetite-and-aggregate mix that simply gets poured into a pothole, no heating required. A patch can be driven over within 30 minutes of repair, Zanko said.

This compound consists of 1- to 2 percent magnetite and crushed asphalt from recycled asphalt pavement (RAP) and recycled asphalt shingles (RAS). The material is then packed into a pothole and “microwaved” until the binder softens and is compactible, thanks to the magnetite.
Magnetite tailings (MTs) are waste generated from magnetite processing, which not only occupy lots of land, but also result in severe pollution to the surroundings. In this paper, the MTs were used as a substitution of limestone (LMs) aggregate in asphalt mixtures.
Uses for Magnetite When used as the aggregate portion of a concrete mix, magnetite increases the density of the concrete to twice that of standard concrete. This so called "heavy concrete" has become a common building material in nuclear plants as well as (in brick form) for the mitigation of radiation in x-ray facilities.

This 'self heal' in achieved by adding in conductive fibers to the asphalt and through the addition of magnetic energy the micro fibers are heated to the ideal temperature to 'heal' the asphalt. Although it is a great idea, I believe that the terminology used is a bit misleading as (in my mind) 'self healing' implies that it would heal without any external …
