Embodiment

[0023] The following examples provide methods and test data for some asphalt binders and aggregates, with and without lubricating substances or lubricants, carried out under conventional hot mix conditions as well as under conditions employing the method of the present invention.

[0024] In these examples, the E-1 compound is a specific compound type that meets the Wisconsin Department of Transportation's ("WIDOT") design life in excess of 20 years for a design load of 1 million equivalent single axle loads (ESAL) road surface requirements. The same applies to E-10, except that it has an ESAL of 10 million. The term ESAL is well known to those working in the asphalt paving industry.

[0025] In general, tall oil soaps and tall oil soaps can be made by reacting tall or refined tall oil with sodium or potassium hydroxide by any of the well-known methods for making soaps. Tall oil and refined tall oil were supplied by Arizona Chemical, Jacksonville, FL; Georgia Pacific, Atlant...

Abstract

The present invention provides a bituminous composition, a process for preparing a bituminous paving composition and process for bituminous paving having lower mixing, paving, and compaction temperatures than for conventional hot-mix paving while retaining sufficient performance characteristics of conventional hot-mix paving. The inventive paving process comprises the steps of injecting a foamable solution comprising a lubricating substance into a heated, asphalt binder to provide a heated, foamed mixture; adding the heated, foamed mixture to a suitable, heated aggregate; further mixing the heated, foamed mixture and heated aggregate to coat the heated aggregate with the heated, foamed, asphalt binder to form a heated paving material; supplying the heated paving material to a paving machine; applying the heated paving material by the paving machine to a surface to be paved; and compacting the applied paving material to form a paved surface.

Description

technical field [0001] The field of the invention relates generally to an asphalt paving composition and an asphalt paving method, and more particularly to an asphalt paving composition comprising a combination of a foam lubricating substance, an asphalt binder, and an aggregate. Background technique [0002] The use of asphalt aggregate mixes for paving roads, driveways, parking lots and the like is well known. Typically, a suitable aggregate mixture comprising crushed stone, gravel, sand, etc. is heated at an elevated temperature of about 270°F to 370°F and mixed with an equally hot asphalt-based binder such as asphalt or Bituminous binder (asphalt plus polymer) is mixed until the aggregate particles are coated with the binder. Paving mixes prepared in this temperature range are often referred to as hot mixes. Mixing is usually done off-site, and the mix is ​​then transported to the paving site and fed to the paver. The mixture of asphalt and aggregate applied to the ro...
