[0084] Rubber powder 12

[0085] Resin 3

[0086] rubber 3

[0087] Crosslinker 8

[0088] Coupling agent 1.5

[0089] Emulsifier (compound) 4.5

[0090] Anti-Aging Agent 8

[0091] Water 142 (add in two times, leave 20 to add during construction)

[0092] Defoamer trace

[0093] The production process is attached figure 1 As shown, the specific control indicators are as mentioned above and will not be repeated here.

[0094] 2. The product performance is as follows:

[0095] Adhesion: >1.2Mpa;

[0096] Waterproof performance: impervious to water for 3 minutes under normal pressure;

[0097] Penetration depth: 10~20mm;

[0098] Tack-free time: 2 hours.

[0099] 3. Application features:

[0100] ①The construction process is the same as before, add 0.2% foaming agent and 20% activator during construction...

Embodiment 2 Embodiment 1 application example

[0103] 1. Raw material ratio (weight ratio):

[0104] Asphalt pavement protective agent base material 100 (formula and processing technology are the same as Example 1)

[0105] Foaming agent 0.5

[0106] Water 8~15

Abstract

The invention relates to maintenance of asphalt roads. The weight percent of a curing agent is: asphalt 100, rubber powder 2-25, resin 3-10, rubber 2-16, the cross linker 2-10, the resin acceptor 1-6,the emulsifier 1-20, some antiaging agent, the active agent 30-300, foaming agent and defoaming agent. The process is: preprocessing materials, composite modifying, emulsifying, adding auxiliary materials to smelt. The construction program is; artificial daub, kneading by the foam maker and curring. The curing agent has the good bonding performance and waterproof effect.

Description

technical field [0001] The invention relates to the protection technology of asphalt pavement of highway engineering. The focus is on preventive maintenance and disease treatment of asphalt pavement. Background technique [0002] Asphalt pavement develops very rapidly due to its good driving performance, high degree of construction mechanization, and fast speed, but it has been plagued by some technical problems that have affected its promotion. These technical problems are mainly the early damage of asphalt pavement (before the design period large-scale disease), including early water damage, rutting, diesel fouling, and early disease caused by poor adhesion of asphalt to aggregate. The rutting problem is also one of the main problems of the early disease of asphalt pavement, which is related to the gradation of asphalt concrete, base strength or material factors. After the pavement is paved, the rutting problem has become a fact and cannot be changed. Therefore, the foll...
