US 2016/0355701 A1 · MODIFIED ASPHALTIC PRODUCT AND PROCESS

Abstract

An asphalt modifying binder product, which is essentially a cut-back bituminous binder, uniquely including a petroleum product, such as diesel fuel or alternatively an organic oil, including vegetable or animal derived fats or oils, or glycol, for use in the manufacture of cold-mix asphalt “CMA” and asphalt treated base products. When mixed with an dense-graded aggregate with fine aggregate fractions, a dense-graded and non-porous cold-mix asphaltic improved product is formulated. The improved product may be employed as a patching/paving material or an asphalt treated base, stays pliable for extended periods of time at an ambient temperature, and again meets the typical required specifications and standards, for stability, flow and voids, when tested as hot-mix asphalt or asphalt treated base.

Dependent claims

A method for formulating a cut-back binder product for mixing with an aggregate, to produce a cold-mix asphalt product, the method comprising the steps of:

a) heating an asphalt base binder;
b) adding a SBS polymer, to form an admixture;
c) blending the admixture until substantially homogenous;
d) cooling the admixture;
e) mixing the admixture with an organic oil to form the cut-back binder product;
f) coating a dense-graded aggregate with the cut-back binder product;
and
g) forming a dense-graded cold-mix asphalt product with the cut-back binder product and the dense-graded aggregate, the dense-graded cold-mix asphalt product pliable and ready for use after storage at an ambient temperature.
