Description
Technical field
The invention belongs to road engineering material field, and in particular to a kind of early-strength waste asphalt pavement cold renewal breast
Liquid, its preparation method and its application.
Background technology
Nearly 1.6 hundred million tons of the waste asphalt mixture quantity that China produces every year, the such huge discarded pitch of quantity is mixed
Material is closed, if not being used, a large amount of soils are not only taken, and pollute environment.Therefore, scientific and efficient utilization waste asphalt is mixed
Material is closed, to promoting resource circulation utilization and environmental protection, realizes that the sustainable development of bituminous paving is significant.
Current asphalt regenerative mainly divides hot recycling and cold renewal.Although hot recycling pavement performance is preferably,
It mixes and stirs the environmental pollution weight that paves in high temperature, and energy consumption is big, while the utilization rate (20-30%) of waste asphalt mixture is relatively low.Breast
Change cold asphalt rehabilitation to mix and stir and construct in normal temperature, waste asphalt mixture utilization rate (70%-90%) is high, with energy-conservation and environmental protection
Advantage, but at present Cold Recycled Mixture with Emulsified Asphalt early strength deficiency seriously restrict its popularization and application.
Cold renewal emulsion is the emulsion being suspended in by small pitch particle in aqueous medium, and cold renewal emulsion is mixed and stirred with reworked material
When, pitch particle formation asphalt membrane close to each other, but now asphalt membrane due to moisture content presence and pitch cohesive force is relatively low, institute
It is relatively low with compound cohesive force, adhesion, decomposition demulsification, moisture content steaming that cold renewal emulsion compound has to pass through emulsion and gathered materials
Original adhesive property could be recovered after hair completely.The strength development of cold renewal emulsion compound is slow, and cold renewal layer is adding
Health must be carried out by spreading before Rotating fields, conditioned time should not be less than 7d, it is necessary to for a long time suspend traffic, this to traffic especially
Urban transportation influence is very big, how to overcome its early strength while the advantages such as asphalt environmental protection, energy-conservation are retained
Deficiency, is the important research direction in road engineering material field.
Chinese patent ZL00808923.X has invented a kind of high-early-strength cement and additive and preparation method thereof, the invention energy
Improve the early strength of cement, but need to add in cement pulverizing course, it is cold that common high-early (strength) cement is used for emulsified asphalt
Regenerating mixture can influence the operable time of compound, be not particularly suited for Bituminous Pavement Cold Regeneration.
Chinese patent ZL200810150504.6 authorizes cold renewal reducing agent and the preparation of a kind of waste asphalt mixture
