Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road surface restoration methods are cumbersome, costly, and inefficient for small areas, requiring bulky machines and additional hot conglomerate layers, and do not allow exclusive use of recycled material.
Innovation Solution
A compact, integrated scarification and recycling assembly that can be connected to a mobile arm of an operating machine, performing scarification and recycling in a single pass, using a regenerating fluid to regenerate and redeposit milled conglomerate directly on the road surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dedicated regeneration machines are used to recycle milled material, then the road surface can be restored, but the operation becomes burdensome and time-consuming due to multiple machines and steps
Solution Approach 1:
The patent combines scarification, recycling, and paving functions into a single integrated machine. The scarifier mill removes and shreds asphalt, the recycler adds binding agents and water to regenerate the material, and the paver redistributes it all in one continuous operation, eliminating the need for separate dedicated machines for each function.
Solution Approach 2:
The single machine performs multiple functions: it acts as a scarifier to remove damaged asphalt, a recycler to regenerate the milled material with binding agents and water, and a paver to redistribute the regenerated material. This multi-functional approach replaces the traditional multi-machine system.
2Adaptability or versatility
If milled material is set aside in a dedicated regeneration machine, then recycling can be performed, but the process requires bulky supporting machines and is not suitable for small zones
Solution Approach 1:
By merging the scarification, recycling, and paving functions into one compact machine, the system eliminates the need for bulky supporting machines. The integrated design allows the machine to perform all operations in sequence without requiring additional equipment, making it suitable for small zones.
3Quantity of substance
If regenerated milled conglomerate is used as a carrier layer, then road traffic can operate, but a further layer of new hot conglomerate must be deposited
Solution Approach 1:
The patent changes the parameters of the milled material by adding binding agents and water during the recycling process, transforming it into a regenerated material with sufficient binding properties. This allows the regenerated material to form a complete, functional road surface layer without requiring an additional hot conglomerate layer.
4Loss of time
If multiple operations are performed separately, then each function can be optimized, but the restoration process becomes more time-consuming and labor-intensive
Solution Approach 1:
The machine performs scarification, recycling, and paving in a continuous one-pass operation. The scarifier removes material, the recycler immediately regenerates it with binding agents and water, and the paver continuously redistributes the regenerated material, eliminating idle time between operations and significantly reducing total restoration time.
