Recycled Pavements Using Foamed Asphalt in MinnesotaRecycled Pavements Using Foamed Asphalt in Minnesota What Was the Need? Foamed asphalt is formed by injecting small quantities of cold, atomized water under pressure into hot asphalt binder On contact with the binder, the water becomes steam, producing an asphalt foam that is mixed with pulverized asphalt pavement materials at the job site.Asphalt Pulverization Soil StabilizationFoamed Asphalt Recycling is an “in place” reconstruction process of existing roads and other pavement sections Recycling is more cost effective than total reconstruction Foamed Asphalt Recycling has been known to cut reconstruction costs by fifty percent.Method Statement for Flexible Pavement Asphalt DrivewayThe purpose of this method statement is to describe steps for flexible pavement that can also include asphalt driveway rehabilitation and road resurfacing The sequence of the work to be carried out shall be as follows Resurfacing Works Partial Reconstruction Works Total Reconstruction Works Cold In Place Recycle (CIPR)

STATE HIGHWAY ADMINISTRATION RESEARCH REPORT

Foamed asphalt stabilized base (FASB) combines combinations of reclaimed asphalt pavement (RAP), recycled concrete (RC), and/or graded aggregate base (GAB) with a foamed asphalt binder to produce a partially stabilized base material The foamed asphalt content is usually too low to fully coat all of the aggregate particles, as is the case in hot.

Pavement Manual Treated Subgrade and Base CoursesThe foamed bitumen increases the shear strength and reduces the moisture susceptibility of granular materials The strength characteristics of foamed asphalt approaches that of cemented materials, but foamed asphalt is flexible and fatigue resistant Foam treatment can be used with a wider range of aggregate types than other of cold mix process.LR 1000 2 State of Illinois SPECIAL PROVISION FOR COLD INPre treatment requires that the lime and water be added at least four hours prior to the addition of the foamed asphalt The treated material must be placed in an air tight container to retain moisture However, due to the hydration process, the moisture content should always be checked and, if necessary, adjusted prior to adding the foamed.Full Depth ReclamationSurface treatment or surface course Finally, a more durable surface treatment or surface course is applied over the new stabilized base course Purpose Stabilized base course Materials Recycled material, asphalt emulsion or foamed asphalt, asphalt rejuvenating agent and possibly aggregate Mix Design.Treatment Guidelines for Soils and Base in Pavement StructuresAsphalt Emulsion (Left) and Foamed Asphalt (Right) , 12 Figure 5 Base Materials Treated with Dual Treatments Asphalt Emulsion (Left) and Foamed , treatment mechanism, material composition, and reaction time must all be considered when selecting a project for treatment 8 LIME TREATMENT.Pavement Manual Surface Treatments♦ 43 Asphalt Treatment (Plant Mixed) Bases ♦ 44 Emulsion and Foamed Asphalt Treatments 5 Performance Graded Binders (PG Binders) ♦ 51 General ♦ 52 Selecting a PG Binder 6 Hot Mix Asphalt Pavement Mixtures ♦ 61 General ♦ 62 HMA Mix Design ♦ 63 Guidelines for Selecting HMA Mixtures.Using Foamed Asphalt as a Stabilizing Agent in Full DepthUsing Foamed Asphalt as a Stabilizing Agent in Full Depth Reclamation of Route 8 in Belgrade, Maine , design a foamed asphalt mix, construction of the foamed asphalt sections and a preliminary , introduced to hot asphalt causing the asphalt to foam and.
