Sustainable Materials For Pavement Infrastructure: Design And Performance Of Asphalt Mixtures Containing Recycled Asphalt Shingles, Samuel B. Cooper, Jr
Sustainable Materials For Pavement Infrastructure: Design And Performance Of Asphalt Mixtures Containing Recycled Asphalt Shingles, Samuel B. Cooper, Jr
LSU Doctoral Dissertations
As the price of liquid asphalt continuously climb, methods are being sought to decrease material costs which will have less impact on ecological systems without compromising material or pavement performance. The use of recycled materials is one method that can replace a percentage of their virgin counterparts, thus reducing the negative impacts on the environment. Asphalt mixture performance is affected by the level of blending that occurs between aged and virgin asphalt binders. The interaction and compatibility of recycling agents (RAs) with recycled asphalt shingles (RAS) and reclaimed asphalt pavements (RAP) have not been thoroughly evaluated since the 1970s. To …
Evaluation Of Volumetric And Mechanistic Properties Of Asphaltic Mixtures: Design, Production And Construction, Samuel Booth Cooper Iii
Evaluation Of Volumetric And Mechanistic Properties Of Asphaltic Mixtures: Design, Production And Construction, Samuel Booth Cooper Iii
LSU Doctoral Dissertations
There has long been an understanding that differences exist between the asphalt mixture designed in the laboratory and the asphalt mixture produced in the asphalt plant. Additionally, variations between the mixtures compacted in the laboratory and mixtures extracted from the roadway have been observed. There is concern that asphalt mixtures produced through the plant and further compacted on the roadway are not representative of asphalt mixtures designed in the laboratory. This is especially a concern when field specimens (i.e. roadway cores) are used to evaluate the quality of the asphalt mixture. For the first time, a national effort has been …
