[0046] nano-SiO 2 5%.

[0047] Wherein, the B group material is composed of the following raw materials according to the mass percentage:

[0048]

Embodiment 3

[0050] Best practice:

[0051] Asphalt pavement assembly type rapid repair technology interlayer bonding material is composed of three groups of materials A, B and accelerator. The ratio of the three groups of materials is A:B:accelerator=100:33:6 according to the mass ratio;

[0052] Group A consists of the following raw materials according to mass percentage:

[0053] Bisphenol A type epoxy resin 93%;

[0054] nano-SiO 2 7%.

[0055] Wherein, the B group material is composed of the following raw materials according to the mass percentage:

[0056]

[0057] In group A, add nano-SiO 2 filler, due to nano-SiO 2 Large specific surface area and high surface energy show extremely high activity, and nano-SiO 2 The surface is covered by a large number of organic groups, which improves the compatibility with the organic matrix, enhances the adhesion between the nanoparticles and the epoxy matrix, facilitates the transfer of stress, can bear a certain load, consumes impact e...

Abstract

The invention discloses an asphalt pavement assembly type rapid repairing technology interlayer bonding material and a preparation method thereof. The preparation method comprises the following steps:blending bisphenol-A epoxy resin and nanometer SiO2 according to a certain proportion at 50 DEG C till a mixture is milky white and is free from powdery particles; sequentially adding modified aliphatic amine, polyamide, an amine curing agent, polysulfide rubber and a coupling agent according to a certain proportion at room temperature for mixing, stirring till group B materials are pale brown, and storing at room temperature and under a drying condition for 1.5 months; and mixing group A materials, the group B materials and a promoter in parts by mass according to a ratio of 100 to (30 to 35) to (5 to 7) to obtain the asphalt pavement assembly type rapid repairing technology interlayer bonding material. The asphalt pavement assembly type rapid repairing technology interlayer bonding material has the advantages of longer construction time, good fluidity, simple construction, quick increase in strength after spreading, good bonding performance with different pavement materials under awet interface condition, short traffic opening time, and controllable gelation time and curing rate.

Description

technical field [0001] The invention belongs to the technical field of road engineering materials, and in particular relates to an asphalt pavement assembly type rapid repair technology interlayer adhesive material and a preparation method thereof, which are applied to the interlayer bonding of new and old road surfaces in the asphalt pavement assembly type rapid repair technology. Background technique [0002] At present, my country's expressway mileage has become the first in the world, and asphalt pavement accounts for more than 90% of expressways. Asphalt pavement is basically adopted for newly-built municipal roads, and asphalt overlay is mostly carried out on the original cement concrete pavement. The proportion of local road asphalt pavement is also increasing. It is extremely disproportionate to the substantial increase in the proportion of asphalt pavement in paved roads. The maintenance and repair technology of asphalt pavement in my country is mainly based on the...
