In modern urban transportation construction, road smoothness, durability, and safety are key indicators of quality. Modified resin pavement, with its superior performance and broad application prospects, has become the preferred material for numerous road construction projects. This article provides a detailed introduction to the construction process of modified resin pavement, from preparatory stages to final acceptance, comprehensively analyzing key construction points and precautions.

I. Preparatory Work

1. Design and Planning

Needs Analysis: Analyze mechanical properties and durability requirements based on road usage (e.g., highways, urban arterial roads) and expected service life.
Scheme Selection: Compare characteristics of different modified resin materials, including compressive strength, wear resistance, and waterproof performance, to select the most suitable option.
Cost Budget: Develop a reasonable material procurement plan and construction budget based on project scale and funding.

2. Material Preparation

Modified Resin Selection: Choose resins with excellent adhesion, weather resistance, and anti-aging properties as required by the design.
Filler Selection: Use appropriate fillers (e.g., quartz sand, basalt fiber) to enhance mechanical strength and stability.
Additives: Incorporate additives to improve flexibility and crack resistance.

3. Site Preparation

Site Clearing: Ensure the construction area is free of debris, standing water, and obstacles to provide a clean working environment.
Foundation Treatment: Compact and level the base to ensure adequate load-bearing capacity.
Drainage System: Install effective drainage systems to prevent water damage during construction.

II. Construction Process

1. Base Course Treatment

Surface Leveling: Use professional equipment to grind the base surface, ensuring flatness meets design standards.
Cleaning: Remove dust, oil, and other contaminants from the base surface.
Moistening: Lightly spray water to maintain moderate moisture on the base surface, facilitating resin adhesion.

2. Primer Application

Primer Mixing: Blend modified resin and curing agents proportionally and mix thoroughly.
Uniform Application: Apply the primer evenly onto the base using trowels or brushes to form a thin, consistent layer.
Curing: Allow the primer to dry and cure naturally, typically taking several hours to one day.

3. Modified Resin Layer Installation

Installation Method: Use specialized screed loaders or manual spreading to ensure uniform resin distribution without air bubbles.
Compaction: Compact the resin layer with machinery to ensure tight bonding with the base and minimal gaps.
Temperature Control: In low-temperature conditions, apply heating measures to maintain material fluidity and avoid construction difficulties.

4. Protection Layer Installation

Material Selection: Choose protection layer materials (e.g., asphalt concrete, cement-stabilized macadam) based on thickness and design requirements.
Installation Method: Lay according to design specifications, ensuring thickness and flatness meet standards.
Compaction Forming: Use rollers to compact the protection layer to the required density.

5. Inspection and Repair

Visual Inspection: Conduct a comprehensive visual check for defects.
Physical Testing: Use deflectometers, flatness meters, and other tools to test physical properties (e.g., flatness, thickness).
Local Repair: Fix identified issues locally to ensure overall quality compliance.

III. Post-Construction Maintenance

1. Regular Inspections

Routine Patrols: Periodically inspect the pavement to identify and address potential damage.
Maintenance Records: Document inspection and maintenance activities to support long-term road management.

2. Maintenance Measures

Moisture Protection: Implement moisture retention measures in winter or arid regions to ensure construction quality.
Anti-Slip Treatment: Apply anti-slip measures after rainy or snowy seasons to prevent vehicle skidding.

3. Emergency Repair

Rapid Response: Establish an efficient emergency repair mechanism for prompt action during incidents.
Technology Updates: Continuously improve emergency repair techniques alongside technological advancements.

The construction of modified resin pavement is a systematic engineering process involving design, material preparation, site setup, construction, and post-maintenance. Adherence to standardized procedures and strict quality control ensures optimal performance and service life. In future road projects, modified resin pavement will continue to leverage its advantages, contributing to urban transportation development.
