Dry Paver Adhesive Composite for Vehicular Load Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for installing paver tiles over concrete driveways for vehicular use are costly, disruptive, and lack a reliable method for achieving durable adhesion, as conventional pavers are not designed for vehicular applications and require messy and time-constrained hydration and curing processes.
Innovation Solution
A dry concrete mix comprising Portland cement, silica sand, alumina silicate, and a latex or acrylic polymer is used to create a paver adhesive that can be applied in a dry state, allowing paver tiles to be laid without immediate hydration, followed by hydration and curing to achieve strong adhesion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional paver installation methods are used over existing concrete, then the installation process is simple, but the adhesion strength and durability for vehicular use is insufficient
Solution Approach 1:
The patent uses a composite adhesive material comprising Portland cement, silica sand, alumina silicate, and polymer modifiers (latex or acrylic). This composite formulation provides both strong adhesion for vehicular loads and a manageable application process, resolving the contradiction between strength and complexity.
2Ease of operation
If paver adhesive is applied in wet form, then adhesion is achieved, but the installation process becomes messy and time-constrained due to immediate hydration and curing
Solution Approach 1:
The patent applies the adhesive in a dry, unhydrated state before paver placement, allowing installers to work without time constraints related to curing. The hydration and curing process occurs after installation, eliminating the mess and time-pressure associated with wet adhesive application while maintaining strong adhesion.
3Reliability
If existing concrete driveway is completely removed and replaced, then a durable surface is achieved, but the process becomes costly and disruptive to landscaping
Solution Approach 1:
The patent allows installation of pavers over the existing concrete substrate without complete removal. The dry adhesive is applied to the existing surface, pavers are laid, and then the adhesive is hydrated and cured, creating a durable overlay that preserves the existing base and minimizes disruption to landscaping and reduces costs.
Solution Approach 2:
The patent creates a nested structure where the new paver layer is installed within and over the existing concrete driveway. The dry adhesive layer serves as an intermediary between the old substrate and new pavers, allowing the new construction to be embedded within the existing structure rather than requiring complete demolition and replacement.

AI summary
Disclosed herein are paver adhesives including dry concrete mixes. The paver adhesive can include cement, silica sand, alumina silicate, and latex or acrylic polymer. The paver adhesive can be configured to be applied to a substrate in a dry state. The paver adhesive can be configured to become hydrated subsequent to pavers being installed over the paver adhesive, and the paver adhesive can be configured to cure and adhere paver tiles to the substrate following the hydrating.
