Highway construction and maintenance in coastal environments presents unique logistical nightmares. The Agras T100 solves the critical challenge of precise material delivery along narrow highway corridors—this field report documents 47 operational days of real-world deployment data from a coastal highway rehabilitation project in Southeast Asia.
Field Context: Coastal Highway Rehabilitation Project
Our team deployed the Agras T100 for delivering road marking materials, sealant compounds, and lightweight construction supplies along a 12.3-kilometer stretch of coastal highway undergoing rehabilitation.
Traditional ground-based delivery methods faced three persistent obstacles:
- Traffic disruption requiring lane closures lasting 4+ hours per delivery cycle
- Salt corrosion degrading vehicle components within weeks
- Tidal flooding blocking access roads during monsoon season
The Agras T100's aerial delivery capability bypassed these ground-level constraints entirely.
Expert Insight: Coastal operations demand obsessive attention to battery thermal management. We discovered that pre-cooling batteries to 18°C before deployment—rather than the standard 25°C—extended flight cycles by 12 minutes in 85% humidity conditions. The T100's intelligent battery system adapts discharge curves automatically, but starting from a lower thermal baseline gives the chemistry more headroom before thermal throttling kicks in.
RTK Fix Rate Optimization for Linear Infrastructure
Highway delivery requires following precise linear paths with minimal lateral deviation. The Agras T100's RTK positioning system achieved a Fix rate exceeding 98.7% throughout our deployment when properly configured.
Base Station Placement Protocol
Optimal RTK performance along linear corridors requires strategic base station positioning:
- Place base stations at elevated positions perpendicular to the flight path
- Maintain maximum 2-kilometer spacing between base stations for continuous coverage
- Avoid placement near metal structures, power lines, or reflective surfaces
- Ensure clear sky view above 15° elevation angle in all directions
Our coastal environment introduced multipath interference from water surfaces. We mitigated this by positioning base stations minimum 50 meters inland from the waterline.
Centimeter Precision in Practice
The T100 maintained ±2.5cm horizontal accuracy and ±5cm vertical accuracy during delivery runs. This precision proved essential for:
- Depositing sealant materials in exact crack locations identified by prior multispectral surveys
- Avoiding overhead power lines with consistent 8-meter clearance
- Maintaining safe distances from active traffic lanes
Nozzle Calibration for Material Delivery
While the Agras T100 is primarily designed for agricultural spraying, its delivery system adapts effectively for construction material application with proper nozzle calibration.
Spray Drift Management
Coastal winds averaging 15-22 km/h created significant spray drift challenges. We implemented these countermeasures:
- Reduced operating altitude from standard 3 meters to 1.8 meters above target surface
- Increased droplet size through nozzle pressure adjustment to 2.5 bar
- Scheduled operations during early morning windows (0530-0830) when wind speeds dropped below 12 km/h
- Activated the T100's drift compensation algorithm, which automatically adjusts spray timing based on real-time wind sensor data
Pro Tip: The T100's onboard anemometer updates wind readings every 200 milliseconds. For maximum drift compensation accuracy, fly perpendicular to prevailing wind direction rather than parallel. This gives the compensation algorithm more correction authority and reduces material waste by approximately 18% compared to downwind flight paths.
Swath Width Configuration
Highway marking applications required narrower swath widths than typical agricultural use:
| Application Type | Swath Width | Flight Speed | Material Flow Rate |
|---|---|---|---|
| Lane marking primer | 1.2m | 4 m/s | 0.8 L/min |
| Crack sealant | 0.6m | 2 m/s | 1.2 L/min |
| Surface treatment | 3.0m | 5 m/s | 2.4 L/min |
| Lightweight supply drop | N/A | 6 m/s | Payload release |
The T100's variable-rate application system maintained ±3% flow consistency across all configurations.
IPX6K Performance in Salt-Spray Environments
Coastal highway operations expose equipment to corrosive salt spray continuously. The Agras T100's IPX6K rating proved its value during our 47-day deployment.
Environmental Stress Testing Results
Our operational environment included:
- Daily salt spray exposure from breaking waves within 200 meters
- Humidity levels consistently above 80%
- Occasional direct rain during unexpected weather changes
- Fine sand particles carried by onshore winds
Post-deployment inspection revealed:
- Zero moisture ingress in motor housings
- No corrosion on exposed electrical contacts
- Propeller blade leading edges showed minor salt accumulation (easily cleaned)
- All sensor windows maintained optical clarity
Maintenance Protocol for Coastal Operations
We developed an enhanced maintenance schedule specifically for salt-spray environments:
- Daily: Fresh water rinse of all external surfaces (5 minutes)
- Every 3 flights: Compressed air cleaning of ventilation ports
- Weekly: Silicone-based corrosion inhibitor application on exposed metal components
- Bi-weekly: Full sensor calibration verification
This protocol added approximately 20 minutes of daily maintenance time but prevented any corrosion-related failures throughout the deployment.
Multispectral Integration for Precision Targeting
Prior to delivery operations, we conducted multispectral surveys to identify exact material application points. The T100's compatibility with multispectral sensor payloads enabled a two-phase workflow.
Phase 1: Survey and Mapping
Multispectral imaging identified:
- Pavement cracks requiring sealant (detected via thermal differential signatures)
- Surface degradation zones needing treatment (identified through reflectance analysis)
- Vegetation encroachment areas requiring herbicide application
Phase 2: Precision Delivery
Survey data integrated directly into the T100's mission planning software. The drone followed pre-programmed paths with material release triggered by GPS waypoint proximity rather than manual operator input.
This automated approach achieved:
- 94% target accuracy for crack sealant application
- Zero material waste on non-target surfaces
- Consistent coverage density regardless of operator fatigue

Common Mistakes to Avoid
Neglecting battery conditioning in humid environments. High humidity accelerates battery self-discharge and can trigger false low-voltage warnings. Always store batteries in climate-controlled containers between flights and verify charge levels immediately before deployment.
Using agricultural spray settings for construction materials. Construction sealants and primers have different viscosity profiles than pesticides. Failing to recalibrate nozzle pressure and flow rates results in uneven application and clogged nozzles.
Ignoring multipath interference near water. Coastal operations near reflective water surfaces can degrade RTK accuracy significantly. Position base stations inland and verify Fix status before each mission rather than assuming previous settings remain valid.
Skipping post-flight salt removal. Even brief exposure to salt spray initiates corrosion processes. The "I'll clean it tomorrow" approach leads to cumulative damage that voids warranty coverage and causes premature component failure.
Overloading payload for "efficiency." Operating at maximum payload capacity in coastal wind conditions reduces maneuverability and increases battery drain. We found 85% payload capacity provided the optimal balance between efficiency and operational safety margin.
Frequently Asked Questions
Can the Agras T100 deliver solid materials or only liquids?
The T100's primary design centers on liquid application through its spray system. However, the platform supports payload modifications for granular material spreading and lightweight package delivery. Our highway project utilized both liquid sealant application and small parts delivery (fasteners, sensors) using aftermarket payload release mechanisms. Maximum solid payload weight should not exceed 35kg to maintain stable flight characteristics.
How does RTK performance degrade in heavy rain conditions?
RTK Fix rate drops to approximately 92-94% during heavy rainfall due to signal attenuation. The T100's positioning system automatically switches to RTK Float mode when Fix is unavailable, maintaining ±15cm accuracy—sufficient for most delivery operations but inadequate for precision crack sealing. We recommend suspending precision operations when rainfall exceeds 10mm/hour and resuming when conditions improve.
What training is required for highway delivery operations?
Operators should complete standard Agras T100 certification plus additional training in linear infrastructure flight planning, traffic management coordination, and construction material handling. Our team required 40 hours of supervised flight time before achieving consistent delivery accuracy. Familiarity with local aviation regulations regarding flights near roadways is mandatory—many jurisdictions require specific waivers for operations within highway rights-of-way.
The Agras T100 transformed our coastal highway rehabilitation project from a logistics nightmare into a streamlined operation. The combination of centimeter precision, IPX6K durability, and intelligent battery management delivered measurable improvements in efficiency, safety, and material utilization.
