Method for constructing scientifically engineered and constructed unpaved runways

A method for constructing an unpaved surface, the method comprising the steps of:

• spreading crushed aggregate over an associated base;
• adding liquid to the crushed aggregate to a certain moisture content;
• applying a composition to the moistened aggregate, wherein the composition comprises:
• a binder comprising:
• a carboxylic acid, an ester, or a thermoplastic polyolefin;
• a synthetic isoalkane;
• and
• an adhesion promoting compound, wherein the adhesion promoting compound is selected from a group consisting of organic amines, polyamides, borates, imidazoline amides, amide esters, aminoesters, silanes, and siloxanes;
• reclaiming a layer of the unpaved surface;
• and
• applying the composition as a seal coat.

A method for constructing an unpaved surface, the method comprising the steps of:

• spreading crushed aggregate over an associated base, wherein the crushed aggregate is profiled with a 2 to 2.5% crown which extends from a centerline of the unpaved surface to each shoulder;
• adding liquid to the crushed aggregate to a certain moisture content;
• applying a composition to the moistened aggregate, wherein the composition comprises:
• a binder comprising:
• a carboxylic acid, an ester, or a thermoplastic polyolefin;
• a synthetic isoalkane;
• and
• an adhesion promoting compound, wherein the adhesion promoting compound is selected from a group consisting of organic amines, polyamides, borates, imidazoline amides, amide esters, aminoesters, silanes, and siloxanes;
• windrowing about two to three inches of the treated aggregate to each side of the unpaved surface;
• adding an additional of the composition to the unpaved surface;
• using a grader to windrow again the upper two to three inches of the treated aggregate;
• grading the windrowed aggregate back on to the unpaved surface;
• once the treated aggregate is at or near optimum moisture content, the treated surface layer is compacted to between about 95% to about 98% density;
• and
• after compaction, the remaining about 20% of the composition is topically applied to the compacted surface.
