C. Mix required for a given Curb Form
Use the following calculations to help determine the quantity of mix required for any given curb
form. It is usually a good practice to reduce yield per cubic yard/per ton by 5% to allow for
waste, shortages, etc.:
CONCRETE: 3,888 = lineal feet of curb per cubic yard
Area of curb form
in Square Inches
ASPHALT: 1920 = lineal feet of curb per ton
Area of curb form
in Square Inches
NOTE: Contact Miller Spreader Customer Service to obtain the Curb Form Design Sheet for
the Curb Form you are using to obtain the square inch area of the curb form.
Choosing the appropriate Auger Size for a given Curb Form
Curbilders can be equipped with one of four (4) different extrusion auger assembly sizes.
These sizes are a nominal 5”, 6”, 8”, and 10” in diameter. Note: The 10” diameter auger is
designed to work on the MC-850 and MC-900 Curbilders only.
 The square inch area and height of a curb form design are to a large degree, but
not solely, determine which auger assembly size is correct for any given curb form.
For purposes of initially matching an auger size to a particular curb form use the
curb form area: Curb Form width X height less the area of sloped side(s).
Exceptions to this guideline will be noted at the end of this section.
The following examples will help you determine the correct auger size to use with a curb form.
Please refer to the following chart.
Auger Size Min Sq
Inch Area
Max Sq
Inch Area
Min Height Max Height Min Width Max Width
5” 18 32 3” 6” 5” 9”
6” 33 55 4” 10” 6” 14”
8” 56 119 6” 18” 8” 18”
10” 120 220 8” 18” 10” 18”
 The area of each curb form is available from the Miller Spreader Company. Locate the
stamped number (one (1) to five (5) digits/letter) on the outside face of the curb form
mounting flange. Contact the Customer Service department with this number and a
Miller service representative can supply the area for that curb form. You can consult the
factory for curb form and auger size recommendations.
 IMPROPER SELECTION OF THE AUGER SIZE FOR A CURB FORM CAN CAUSE
EXCESSIVE COMPONENT WEAR, POOR MACHINE PERFORMANCE AND/OR
THE COMPLETE FAILURE TO OPERATE.
