Cold Mixes

A VERSATILE MACHINE FOR MANY PRODUCTS

 

All States' pugmill is a continuous-type mix plant that can process five tons of material per minute. Aggregate fed into a hopper rides a conveyor which dumps the material into a mixing chamber. It is then carefully blended with metered amounts of liquid asphalt emulsions which results in a quality product tailored to your needs.

To ensure product excellence, we first send product samples of your material to our Holliston, MA laboratory where their composition and properties are analyzed. Only after extensive testing do we select the combination of aggregate and asphalt emulsion that best suits your conditions

At our Sunderland yard we use the pugmill to pre-treat stone for chip seals and to stockpile cold patch for pothole repair. In your yard, you supply local aggregate, washed or screened gravel, sand-graded aggregate, or pavement millings to be blended with ALL STATES' asphalt emulsions or cutback asphalts to produce cold mix, cold patch, or pre-treated stone.

To guarantee quality, all our pugmill products use laboratory-designed mixes .

COLD MIX-A SMART CHOICE

Our most versatile pugmill product, however, is cold mix. We combine our many years of experience with controlled lab analysis and research to formulate open and dense graded cold mixes for road base, binder, and top course.

A sampler of ALL STATES' uses for cold mix: on a gravel road upgrade project, we specified 1 1/2" stone blended with asphalt emulsion in our cold mix design to ensure a strong, long-lasting pavement. The mix was placed in 3" mat with a conventional asphalt paver. In another project we designed a formula to allow incorporation of local aggregate to produce a thin cold mix for shim and leveling. A chip seal was placed over the leveling course a month later. ALL STATES recommends that newly placed cold mix pavements be sealed with a surface treatment within a year of placement.

Because of its resilience, cold mix is especially well-suited for upgrading and  strengthening thin pavements.  Used for base and surface courses, cold mixes are resistant to fatigue and cracking because of their flexibility, high void volume, and tendency for self-healing. Graded stone can be produced into a high quality cold mix that meets AASHTO design guidelines for a comparable hot-mix pavement.

Using cold mix allows you to reduce your transportation and materials expenses.
