Research ideas is the first US Devi real Vic suggested mixing the construction temperature 125 gradation mix(http://www.chinaasphaltplants.com/Photo-Gallery/category/2-Asphalt-Batch-Mix-Plant-PMT.html) design, three kinds of gradation, to determine the optimum asphalt content of various white. This optimum asphalt content, at different temperatures Marshall molded specimens observed porosity variation, and thus to determine the best mix construction temperature.
With the molding temperature change specimen porosity trends. The three kinds of graded E-WMA similar variation. Overall, in the temperature region Q of the test, along with the rise of the molding temperature, the porosity was decreased. 100 is a demarcation point the molding temperature of 100 or more, the void ratio changes slowly; but below 100, with the lower molding temperature, the porosity of the specimen Acute distant increases. Molding temperature of 90, 3-graded E-WMA porosity have reached more than 5%. This shows that the 100, the the lubrication role played warm mix additives has not offset the the asphalt(http://www.chinaasphaltplants.com/Photo-Gallery.html) work impatient mysterious reduce the impact.
