Abstract
Abstract A paving composition and method of making it in which the binder is a bituminous gel formed by mixing in a colloid mill from about 83% to about 97% of a hot bituminous material with from about 2% to about 16% of water and from about .1% to about 11% of a gelling agent. The gel while in a heated state is mixed in a mixer with an aggregate at the rate of from about 3% to about 8% based upon the weight of the aggregate to form a paving composition.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
158 words
A METHOD OF MAKING A PAVING COMPOSITION COMPRISING THE STEPS OF MECHANICALLY MILLING IN A COLLOID MILL A BITUMINOUS MATERIAL SELECTED FROM THE CLASS CONSISTING OF ASPHALT, MIXTURES OF ASPHALT, TAR, AND PITCH, AND A WATER SOLUTION OF A GELLING AGENT IN THE FORM OF A SOAP TO PRODUCE A BITUMINOUS GEL CONTAINING FROM ABOUT 83 TO ABOUT 97 PERCENT BITUMINOUS MATERIAL MILLED INTO A COLLOIDAL PARTICLE SIZE, FROM BOUT 2 TO ABOUT 16 PERCENT WATER, AND FORM ABOUT 0.1 O ABOUT 11 PERCENT OF SAID GELLING AGENT, SAID BITUMINOUS MATERIAL BEING AT A TEMPERATURE OF FROM ABOUT 200* TO 260* F AND SAID WAER SOLUTION BEING AT A TEMPERATURE OF FROM BOUT 65* TO ABOUT 100*F WHEN THEY ARE MILLED TOGETHER, AND MIXING SAID GEL WHILE AT A TEMPERATURE OF FROM ABOUT 160* TO ABOUT 210* WITH AN AGGREGATE TO FORM A PAVING COMPOSITON IN WHICH THE AGGREGATE IS COATED WITH THE BITUMINOUS MATERIAL IN THE GEL.
Claim 2
