Paving Material Using Powder Epoxy Resin for Drainage Pavement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drainage pavements face issues with aggregate loss and require early repairs due to high air voids and weak binding areas, and existing resin-based solutions are hazardous, difficult to handle, and have limitations in temperature and moisture conditions, while binder emulsions lack sufficient durability and fast decomposition.
Innovation Solution
A paving material composed of a non-water-soluble epoxy resin, a binder emulsion, and an amine compound hardener, mixed on-site, which allows for fast decomposition, strong binding, and improved durability, enabling early traffic access and resistance to high temperatures and moisture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If liquid resins (methacrylate resin, acrylate resin) are applied to strengthen drainage pavement surface, then surface strength is improved, but handling difficulty and safety hazards increase due to classification as dangerous materials
Solution Approach 1:
The invention changes the physical state parameter of the resin from liquid to powder form. This transformation eliminates the handling difficulties and safety hazards associated with liquid resins while maintaining the strength-enhancing functionality. The powder resin can be easily mixed with binder emulsion and applied without the restrictions of liquid resin handling.
Solution Approach 2:
The invention creates a composite material system combining powder resin with binder emulsion. This composite approach allows the resin to be mixed with the emulsion in a controlled manner, achieving both strength improvement and ease of application. The composite material overcomes the limitations of using liquid resins alone.
2Strength
If liquid resins are applied on high temperature or moist surfaces, then surface strengthening is achieved, but application restrictions increase due to temperature and moisture sensitivity
Solution Approach 1:
The invention changes the physical state of the resin from liquid to powder, which fundamentally alters its reactivity characteristics. The powder form remains stable under high temperature and moisture conditions during transport and storage, and only reacts when mixed with the binder emulsion on-site. This eliminates the application restrictions associated with liquid resins.
3Ease of operation
If binder emulsion is used to strengthen drainage pavement, then application ease is improved, but durability and binding strength become insufficient
Solution Approach 1:
The invention creates a composite material system combining binder emulsion with powder resin. The binder emulsion provides ease of application and good adhesion to the pavement surface, while the powder resin contributes high binding strength and durability. This composite approach synergistically combines the advantages of both materials while overcoming their individual limitations.
Solution Approach 2:
The invention merges the functional properties of binder emulsion (ease of application, adhesion) with those of powder resin (binding strength, durability). By combining these materials in a single system, the invention achieves both ease of operation and sufficient binding strength that neither material could provide alone.
4Strength
If epoxy resin and hardener are mixed into binder emulsion to improve durability, then durability is enhanced, but decomposition time increases and traffic opening is delayed
Solution Approach 1:
The invention segments the resin component into a separate powder form that is mixed with the binder emulsion immediately before application. This segmentation allows the resin to remain stable during transport and storage, and only initiates decomposition and hardening after mixing and application. This eliminates the extended decomposition time associated with pre-mixed epoxy resin emulsions.
