Orthogonal Test Research on Molding and Curing for Cold Recycle Mix with Emulsified Asphalt

摘要

Cold recycle mixture with emulsified asphalt is a material which is economical, environmental and energy saving. Now it is widely applied to road recycling engineering, while there is no unified standard for its molding and curing methods. The orthogonal test shows that cold recycle mix with emulsified asphalt can get the better technical indicators after the molding and curing methods. At first, each side 50 times compaction after mixture putting into mold. Then put specimen side in the 60°C wind drying oven at least 40 hours. Next take the specimen out and compact each side 25 times immediately. Finally put specimen side on the ground at least 12 hours at room temperature, and then take the test-piece from the mold for test.
