B. Extruding Curb over vertical Dowel Pins

With a Miller Curbilder, curb can be extruded over vertical dowel pins. This is accomplished

by raising the machine with the leveling screws at each wheel assembly in order to allow the

screw housing to pass over the pins. Curbing over dowel pins also requires a special curb

form. The form must be made with an elevated auger opening to accommodate the raised

auger assembly. It must also incorporate an opening at the bottom of the mounting flange to

allow the pins to pass into the form as the machine moves over them.

Curb forms for curbing over pins are made for a specific pin height. Therefore, the pins

cannot exceed the pin height that the curb form was designed for. Also, pin placement is

critical. Pins must be on line, not more than ½” left or right of center to prevent pins from

hitting the form.

The most important aspect to remember when considering curbing over pins is that

there must be a minimum of 5” between the top of the finished curb and the top of the

pin.

For example, to curb over 1” pins, the curb height must be 6”; over 2” pins, the curb height

must be 7”; over 3” pins the curb height must be 8”. In most cases, the Curbilder cannot

extrude rebar and pass over pins at the same time.

C. Extruding Curb Under an existing Guardrail

A Miller Curbilder Model MC-655 has an offset frame, auger housing and hopper so that

asphalt curb can be placed under existing guardrail. Supply the Miller Spreader Customer

Service Department a drawing showing the curb form shape and the guardrail dimensions

under which the curb must be placed. Our Customer Service Department will evaluate the

feasibility of your job your application.

D. Extruding New Curb over Old Curb

A Miller Curbilder can extrude new curb over old curb. A special curb form is required.

Roads that have several layers of pavement built up against the curb will diminish the curb

height. Extruding new curb over the old can increase the curb height. To build this special

curb form, both the old curb form design and the new curb form design are required. Consult

with the factory about your specific requirements.

E. Extruding Curb into an Offset Ditch

A Miller Curbilder can extrude a new curb into an excavated ditch/trench at the edge of a

paved road surface. A special curb form is required. There are some limitations to this

procedure depending on curb size, the amount of offset required and the distance to the
