Road Surface Carrier Material for Uniform Skid Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing road surfaces lack efficiency in achieving high initial skid resistance and uniform surface texture, and do not effectively integrate sprinkling materials without causing mechanical damage or requiring separate manufacturing processes.
Innovation Solution
A method involving a carrier material with embedded chippings, applied to the road surface using a road paver, where the chippings are integrated into the surface layer with a binder, creating a uniform and non-uniform pattern for enhanced grip, and incorporating photocatalytically active materials for pollution reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical spreaders are used to apply sprinkling material to the top layer, then initial skid resistance can be increased, but the sprinkling material application is time-consuming and labor-intensive
Solution Approach 1:
The patent combines the road surface construction process with the sprinkling material application process into a single integrated operation. The sprinkling material is mixed into the top layer material itself, eliminating the need for separate mechanical spreading operations and significantly improving productivity while maintaining initial skid resistance.
Solution Approach 2:
The sprinkling material is pre-mixed into the top layer material before application to the road surface. This preliminary incorporation ensures uniform distribution and eliminates the need for subsequent spreading operations, resolving the contradiction between achieving adequate skid resistance and maintaining construction efficiency.
2Reliability
If sprinkling material is applied to the top layer separately, then grip can be improved, but the surface texture becomes non-uniform and bumps are created
Solution Approach 1:
The sprinkling material is merged with the top layer material in a homogeneous mixture before application. This ensures that the grip-enhancing material is uniformly distributed throughout the top layer, creating a consistent surface texture without bumps or irregularities, while still improving road grip.
Solution Approach 2:
The patent achieves homogeneity by mixing the sprinkling material thoroughly with the top layer material. This uniform distribution ensures consistent surface properties across the entire road surface, eliminating the non-uniform texture and bumps that result from separate application methods.
3Stability of the object's composition
If a separate manufacturing process is used to equip carrier material with sprinkling material, then integration is achieved, but the process becomes complex and time-consuming
Solution Approach 1:
The patent merges the mixing of sprinkling material with top layer material into a single conventional mixing operation. This eliminates the need for separate equipment to equip carrier material with sprinkling material, reducing process complexity while ensuring stable integration of the sprinkling material into the road surface structure.
