Natural asphalt drilling and asphalt additive

Natural asphalt in road asphalt

Mixture of natural asphalt into asphalt relates to a base stock composition comprising a blend of natural asphalt and a rubber latex residue. The base stock may be used alone as a paving material or emulsified to form a natural asphalt emulsion having a variety of uses.Mixture of natural asphalt enforce asphalt against rutting and thickness of the asphalt with become thin.

Natural asphalt in asphalt

The present invention is directed to an asphalt cement composition formed from petroleum asphalt, natural asphalt, reactive oil, and an elastomer. The elastomer has a gel content of up to about 95 percent by weight.

Natural asphalt mixture in asphalt

It has been discovered that asphalt cement can be toughened with natural asphalt and thinned with a reactive oil. Reactive oil is an oil that contains a high content of unsaturated fatty acids. By using a reactive oil, the oil would cure or react after application of the asphalt cement to the highway, thereby allowing for a lower viscosity application by curing later to prevent rutting.

The preferred natural asphalt is asphaltite such as natural asphalt.Natural asphalt preferably one having a melting or softening point near about 300° F. so that it is more easily softened and blended with the petroleum asphalt at such temperatures.

How to mix natural asphalt in asphalt:

An asphalt composition consisting essentially of;

100 parts by weight of a petroleum asphalt;

from about 1 to about 10 parts by weight of a natural asphalt;

from about 1 to about 10 parts by weight of a thinning reactive oil comprising at least about a 60

percent unsaturated fatty acid content having from about 14 to 24 carbon atoms, and

from about 1 to about 10 parts by weight of an elastomer.

Natural asphalt as drilling additive

Natural asphalt is using a variety of organic additives such as dispersing agents, retarders or fluid loss control additives. Natural asphalt prevent interstitial water from filtering into the formation during cement placement, are generally polymer based.
