Regenerant for hot mix plant regeneration as well as preparation method and application of regenerant
The invention belongs to the technical field of asphalt pavement maintenance, and particularly discloses a regenerant for hot mix plant recycling as well as a preparation method and application of the regenerant. The regenerant comprises base oil, a tackifier, an anti-aging agent and an easy-to-melt thermoplastic elastomer. The preparation method comprises the following steps: mixing 100 parts by mass of base oil and 0-40 parts by mass of an easily-melted thermoplastic elastomer, soaking at a preset temperature, and stirring until the easily-melted thermoplastic elastomer is completely melted in the base oil; 2, heating the mixture prepared in the step 1, introducing nitrogen, adding 10-20 parts of a tackifier, and then heating and stirring until the tackifier is completely molten; and adding 0.5-1.5 parts of an anti-aging agent into the mixture prepared in the step 2, heating to 160-170 DEG C, and stirring until the mixture is completely melted into uniform viscous liquid. The regenerant can be used in asphalt plant mixing hot regeneration. The manufacturing method is simple, the regenerant can be specifically compounded according to the road performance requirements of different road grades and different application layers, and the construction cost is low.
本发明属于沥青路面养护技术领域，并具体公开了一种厂拌热再生用再生剂、制备方法及其应用。所述再生剂包括基础油、增粘剂、抗老化剂、易融热塑性弹性体。所述制备方法包括：按质量分数配比将100份的基础油、0～40份易融热塑性弹性体混合，并预设温度下浸泡后，搅拌至易融热塑性弹性体完全融于基础油；将步骤一制备的混合体进行加热并通入氮气，加入10～20份增粘剂，然后加热搅拌至增粘剂完全熔融；向步骤二制备的混合体加入0.5～1.5份抗老剂，升温至160～170℃，搅拌直至完全融变为均匀的黏稠液体。该再生剂可用用于在沥青厂拌热再生中。本发明制作方法简单，可根据不同道路等级、不同应用层位的路用性能要求，有针对性复配再生剂，工程造价低。
