Evaluation of Recycled Mixtures Using Foamed Asphalt

Evaluation of Recycled Mixtures Using Foamed Asphalt ... evaluation of the foamed process using two field sands. Additional tests were conducted by using salvaged pavement materials mixed with a foamed asphalt cement (AC-5) and with a cutback (MC-800) and two emulsions (EA-llM and AES-300). Specimens were prepared, cured, and tested under both dry and wet

EVALUATION OF RECYCLED MIXTURES USING FOAMED

EVALUATION OF RECYCLED MIXTURES USING FOAMED ASPHALT. The economic pressure from higher fuel, asphalt, and material prices, along with the growing use of milling equipment for smoothing pavement profiles and the problems of bridge clearances, have worked together to provide an abundance of salvaged roadway materials that are available for recycling.

The fatigue properties of asphalt mixtures are important inputs for mechanistic-empirical pavement design. To understand the fatigue properties of asphalt mixtures better and to predict the fatigue life of asphalt mixtures more precisely, the energy-controlled test mode was introduced. Based on the implementation theory, the laboratory practice for the energy

Use of foamed asphalt in cold, recycled mixtures

Using a laboratory foaming plant, work was performed on local materials to produce foamed-asphalt-treated cold mixtures. The engineering properties of foamed-asphalt-treated mixes were tested and compared with those of hot recycled mixes. Test results show the benefits of utilizing high percentages (80%) of milled asphalt in foamed asphalt mixes.

In general, there is a desire to increase recycled material use in asphalt mixtures, as long as performance is not adversely affected. Every tonne of recycled waste material is one tonne less of new aggregate and/or bituminous binder required to be produced from finite natural resources, as well as one tonne material less that might otherwise become landfill. However, if 20%
