Waste alphalt regenerating agent and its preparing method

Abstract

A kind of regenerant of wasted asphaltum belongs to the manufacturing field of asphaltum-processing accessory material, includes light oil, rosin, anti-aging agent, anti ultraviolet radiation auxiliary agent and so on and is featured by the following composition, in the amounts of weight: between 75% and 90% of light oil, between 10% and 25% of rosin, between 0.1% and 1% of anti-aging agent and between 0.1% and 1% of anti ultraviolet radiation. Aiming to the character of aged wasted asphaltum, the invention adds rosin, anti-aging agent and anti ultraviolet radiation auxiliary agent to light oil, selects and allocates the components reasonably. The invention have the advantage of finding the material easily, low requirement to the producing equipments, easy producing techniques, low cost, convenient use, obvious regeneration, taking action rapidly and long lasting active force. After practical use, the regenerant of wasted asphaltum in the invention can make the aged wasted asphaltum reach the technical indexes of the original asphaltum and the roads paved with it have almost the same life length as those paved with new asphaltum.

Description

technical field [0001] The invention relates to a waste asphalt regeneration agent capable of restoring the use performance of waste asphalt and a preparation method thereof, which belongs to the technical field of manufacturing auxiliary materials for asphalt processing. Background technique [0002] Asphalt pavement has been widely used on urban and rural roads, especially high-grade highways, for its excellent performance such as smooth driving, no reflection, low noise, small dust, convenient maintenance, and little impact on traffic. However, with the prolongation of use time, various lesions will occur on the asphalt pavement under various loads, making the asphalt pavement slowly turn brittle, lose elasticity, gradually harden, appear cracks, potholes, until aging, and cracks. [0003] The existing pavement maintenance technologies are mainly repairing and refurbishment and pavement regeneration and maintenance. The repairing and refurbishment me...

AI Technical Summary

Problems solved by technology

[0003] The existing pavement maintenance technologies are mainly repairing and refurbishment and pavement regeneration and maintenance. The repairing and refurbishment means re-paving with new modified asphalt. It also causes a large amount of asphalt materials to be wasted in vain; pavement regeneration maintenance uses regenerants mixed with waste asphalt to soften and dissolve the asphalt

Existing imported asphalt rejuvenators are restricted from popularization and application in the domestic market due to their complex composition and high price; domestic regenerants are mainly light oils produced by some petroleum industries such as lubricating oil, diesel oil, engine oil, etc. or their The mixture is used to modify old materials, but due to the single composition, the regeneration effect is not ideal, and a certain amount of new asphalt must be mixed into the old asphalt to meet the use requirements of high-grade pavement
