A kind of asphalt viscosity reducing modifier and preparation method thereof

Abstract

The invention relates to an asphalt viscosity reduction modifier, which is characterized in that the modifier comprises the following components in part by weight: 14-18 parts of activating agent, 20 parts of ammonium fluosilicate, 10-15 parts of kreosote, 15-18 parts of polyethylene and 34 parts of stearic acid. The manufacturing method comprises the steps that the components are added into a reaction container, the temperature is raised to 250 DEG C, and the asphalt viscosity reduction modifier disclosed by the invention is obtained after full stirring and reaction are completed. After the asphalt viscosity reduction modifier disclosed by the invention is simply mixed with asphalt, the asphalt viscosity can be obviously reduced, the construction temperature is reduced, poisoned dust emission is reduced, energy consumption is reduced, simultaneously the compaction of asphalt concrete can be obviously improved, the high temperature performance of the asphalt is improved, and the anti-aging capacity of the asphalt is obviously improved.

Description

【Technical field】 [0001] The invention relates to an asphalt modifier, in particular to an asphalt viscosity-reducing modifier and a preparation method thereof. 【Background technique】 [0002] In recent years, the extensive use of modified asphalt and the increase in the compactness of asphalt pavement have increased the mixing and compaction temperature of asphalt mixture, resulting in energy consumption and waste such as smoke and dust during the production of asphalt mixture. emissions have increased significantly. As early as the 1990s, countries such as Japan and Europe signed the "Kyoto Protocol". These countries promised to greatly reduce greenhouse gas emissions. The hot-mix asphalt industry is also one of the targets that need to reduce emissions. At the end of 2009, at the Global Climate Change Conference held in Copenhagen, the meeting discussed the carbon dioxide emission reduction tasks of various countries and required all countries to control the emission of ...
