Stabilizing and controlling dust from a primitive road

Abstract

A road processing machine may include a frame having a leading end and a trailing end. The machine may also include a first spray bar located at one of the leading end or the trailing end. The first spray bar may be configured to distribute a first material onto a road over which the road processing machine is traveling. The machine may also include at least one of a second spray bar or a broadcast spreader located at one of the leading end or the trailing end opposite the first spray bar. The at least one of the second spray bar or the broadcast spreader may be configured to distribute a second material onto the road. The machine may further include at least one processing tool located between the leading and trailing ends of the frame and being configured to process a material of the road.

         5 . The road processing machine of  claim 4 , wherein the at least one processing tool includes:
 at least one primary tillage element;   at least one contouring element; and   at least one of the secondary tillage element or the mixing element.   
     
     
         6 . The road processing machine of  claim 5 , wherein:
 the primary tillage element trails behind the first spray bar; and   the at least one of the secondary tillage element or the mixing element trails behind the primary tillage element.   
     
     
         7 . The road processing machine of  claim 6 , wherein the at least one processing tool includes at least one secondary tillage element and at least one mixing element. 
     
     
         8 . The road processing machine of  claim 7 , wherein the at least one mixing element trails behind the at least one secondary tillage element. 
     
     
         9 . The road processing machine of  claim 5 , wherein the at least one primary tillage element is configured to penetrate the material of the road up to about 3″ deep. 
     
     
         10 . The road processing machine of  claim 5 , wherein:
 the at least one primary tillage element is configured to disrupt a surface of the road and generate clods of the material; and   the at least one secondary tillage element is configured to generate a finer tilth from the clods of material.   
     
     
         11 . The road processing machine of  claim 5 , wherein the at least one primary tillage element includes at least one of a ripper, a plow, or a rotary hoe. 
     
     
         12 . The road processing machine of  claim 11 , wherein the at least one secondary tillage element includes at least one of a harrow, a cultivator, a serrated blade, or a pulverizer. 
     
     
         13 . The road processing machine of  claim 11 , wherein the at least one mixing element includes at least one of an angled grader blade or a drum equipped with spikes or rakes. 
     
     
         14 . The road processing machine of  claim 1 , wherein the at least one contouring element includes at least one of a straight grader blade, a broom, a rolling drum, a series of weighted rollers, or a leveling frame. 
     
     
         15 . The road processing machine of  claim 14 , wherein the at least one contouring element includes at least one of the rolling drum or the series of weighted rollers configured to compact the material of the road prior to the second material forming a seal over the road. 
     
     
         16 . The road processing machine of  claim 1 , wherein the frame includes a containment basin having at least three walls configured to corral the first material. 
     
     
         17 . A system for processing a road, comprising:
 a distributor including:
 a chassis; 
 a power source mounted to the chassis; 
 a drivetrain driven the power source to propel the distributor; 
 at least one vessel supported by the chassis and configured to hold a liquid material; and 
 a distribution arrangement configured to distribute the liquid material on a surface of the road; and 
   the road processing machine of  claim 1  towed by the distributor.   
     
     
         18 . The system of  claim 17 , wherein the liquid material includes a pretreatment material distributed onto the surface of the road prior to the first material being distributed by the first spray bar.
