Problems solved by technology

That is to say, so far, the water stability mechanism of the oil-stone interface, the influence mechanism of stone properties and the spalling theory, the improvement mechanism of anti-stripping agent, the water damage mechanism of asphalt mixture, etc., the academic and engineering circles have made great achievements in these aspects. The research is still lacking, and no generally accepted theoretical understanding has been formed, especially the in-depth research on the mechanism theory at the microscopic level and molecular atomic scale has not been reported.

Embodiment 1

[0117] 1. Purpose of the test: To test and observe the adhesion level of the interface modifier of the present invention to the stone before and after treatment;

[0118] 2. Test materials: granite rock, basalt rock, matrix asphalt, and the asphalt interface modifier of the present invention;

[0119] 3. Test steps:

[0120] 1. adopt the asphalt interface modifier of the present invention, the mass proportion is:

[0121] Nano silicon oxide (inorganic nano material) 20%;

[0122] Isooctylsilane emulsion (silicon-containing organic compound) 20%;

[0123] Sodium dodecylbenzenesulfonate C 18 h 29 NaO 3 S (anionic surfactant) 0.8%;

[0124] C-15 bactericidal preservative (bactericidal preservative) 0.5%;

[0125] Ethanol 2%;

[0126] The balance is water.

[0127] ②According to the requirements of the specification, select granite and basalt stones with a particle size of 13.2-19mm and a shape close to a cube, and clean the stones according to the requirements of the spe...

Embodiment 2

[0137] Proportioning and test method are the same as embodiment 1, and difference is only wherein do not add C-15 bactericidal preservative and ethanol; Test result is shown in Table 2.

Embodiment 3

[0139] The proportioning and test method are the same as those in Example 1, the only difference being that the inorganic nanomaterial is nano-titanium oxide in the oxide nanomaterial, and the dosage accounts for 1 wt% of the total amount. The test results are shown in Table 2.

Abstract

The invention relates to an asphalt interface modifier and a production method and application thereof. The asphalt interface modifier is a compound or a composition, which can form inverse hydrogen bond energy on surfaces of objects on which the asphalt interface modifier is applied and can improve asphalt-aggregate interface bonding bond energy of asphalt mixtures, namely a compound or a composition which can reduce surface energy on surfaces of objects on which the asphalt interface modifier is applied and can form interface chemical bond bonding. The asphalt interface modifier can improvemicrostructures of aggregate-asphalt interfaces (or structural interlayer interfaces), forms chemical bond energy on the aggregate-asphalt interfaces (or the structural interlayer interfaces), enhances cohesion of asphalt-aggregate interfaces, reduces microdefects and microscomic defects of the asphalt-aggregate interfaces, improves the water stability and various pavement performance of the asphalt mixtures, and finally improves the mechanical performance and the durability of asphalt concrete pavements.

Description

technical field [0001] The invention relates to the technical field of asphalt materials, in particular to an asphalt interface modifier, its preparation method and application. Background technique [0002] The function of asphalt pavement is superior, and it is also the main structural form of road pavement of all grades. The phenomenon of early damage to asphalt pavement in our country is very common. Through investigation and experimental research, it is shown that early damage can be classified into 12 types, among which water damage, transverse cracks, rutting, looseness, potholes, spalling, etc. are all related to the properties of the asphalt interface. Direct relationship. The research results show that improving the adhesion of oil-stone interface has positive significance for improving the road performance (water stability, high temperature performance, low temperature performance, etc.) of asphalt mixture. [0003] Water damage is one of the main diseases of as...
