Abstract
The invention discloses a method for preparing a waterproof and anti-rutted asphalt pavement material. The method comprises the following steps: (1) preparing materials in parts by weight, putting asphalt into a reaction still and heating to melting, then adding ABS epoxy resin and heating and stirring to obtain a material A after the stirring is ended; putting paraffin wax, diatomite, aluminum hydroxide, butyl methacrylate, titanate ester and polyvinyl alcohol into another reaction still and stirring with the temperature being controlled at 150-180 DEG C to obtain a material B after the stirring is ended; putting the material B into the material A and continuously stirring until the materials are uniform and then preserving the heat to obtain the waterproof and anti-rutted asphalt pavement material. The asphalt pavement material prepared using the method provided by the invention is good in stability and can be prevented from deforming and being rutted under the condition that the material contains moisture.
Description
Technical field
The present invention relates to ground surface material technical field, particularly the preparation method of the anti-rutting asphalt ground surface material of a kind of waterproof.
Background technology
Bituminous pavement refers to various types of road surfaces of mixing bitumen for road use material making in mineral material.Asphaltic binder improves the ability of paving the way with pellet opposing driving and the infringement of natural cause road pavement, makes evenness of road surface lack dirt, waterproof, durable in use.Therefore, bituminous pavement is a kind of high class pavement be the most widely used in Road construction.
Bituminous pavement in the presence of moisture, often be subject to the repeated action of traffic loading and temperature harmomegathus, moisture progressively intrudes on the interface of pitch and compound on the one hand, under hydrodynamic effect, the film of asphalt surface is little by little peeled off from mix surface, and then causes compound to lose cohesive force and bituminous pavement destruction occurs.
Rut is the supplementary compacting that road surface structare layer and soil matrix are expert under car Repeated Loading, so that the accumulation tension set that the lateral shift of structural material produces.The principal element affecting the asphalt pavement rut degree of depth is the internal factor of asphalt pavement structure and bituminous concrete itself, and the extraneous factor of weather and the volume of traffic and traffic composition etc.The major cause that rut produces has: (1) asphalt bitumen aggregate ratio is excessive; (2) surface abrasion is excessive: it is inner that (3) rainwater invades bituminous concrete; (4) waveform rut is formed because basic unit causes road surface laterally to be pushed containing unstable interlayer.
