Transparent Binder Road Surface Mix for Aesthetic Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bituminous road surface mixes have a negative aesthetic impact due to their black color, which obscures the natural appearance of crushed stone or inert materials, particularly in urban and historical settings, and lack environmental and cost-effectiveness.
Innovation Solution
A road surface mix using a transparent binder with a viscosity range of 800-16000 cps, composed of ethylene copolymers, ethylene polymers, and oils, which binds crushed stone without altering its natural color, allowing integration in various environments while maintaining structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If bituminous binder is used for road surface mix, then binding strength and structural integrity are achieved, but the black color obscures the natural appearance of crushed stone and creates negative aesthetic impact
Solution Approach 1:
The patent applies color changes by replacing the traditional black bituminous binder with a transparent binder composition. This allows the natural color of the crushed stone aggregate to remain visible, transforming the aesthetic appearance from dark and uniform to colorful and natural, while maintaining the binding function through the transparent binder's adhesive properties.
Solution Approach 2:
The invention extracts the harmful black color property from the binder system by removing bitumen and using alternative transparent binding agents. This extraction of the discoloring component allows the aggregate's natural appearance to be preserved while still achieving the necessary binding strength through the transparent binder's chemical and physical adhesion mechanisms.
2Strength
If transparent binder with high viscosity (8000-16000 cps) is used, then cohesion and adhesion properties are improved, but processing complexity and temperature control requirements increase
Solution Approach 1:
The patent applies parameter changes by specifying a controlled viscosity range (800-16000 cps, preferably 8000-16000 cps) for the transparent binder at processing temperatures of 130°C-180°C. This parameter optimization ensures sufficient cohesion and adhesion strength while maintaining workable processing characteristics through temperature-dependent viscosity adjustment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The transparent binder effectively binds crushed stone, making it visible and enhancing the aesthetic and environmental qualities of road surfaces while being cost-effective and simple to produce, with improved cohesion and adhesion properties.
Implementation Method 1
a transparent binder (B) able to bind the solid inert material and make it visible
Implementation Method 2
Once it cools down, the solid materials are bound and form a compact mass (mix)

AI summary
A road surface mix includes a solid inert material and a transparent binder able to bind the solid inert material and make it visible so that, in view of the transparency of the binder, the resulting compact mass takes the color of the solid inert material and is therefore integrated easily in special valuable settings. The transparent binder includes an ethylene copolypmer and an ethylene polymer and/or oils mixed in such manner that the transparent binder has a viscosity of 800-16000 cps at a temperature of 130-180° C.
