NSV Testing Services: Professional Network Survey Vehicle Solutions
Our NSV Survey services combine cutting-edge equipment with experienced engineers to deliver comprehensive road condition data quickly and safely.
Professional NSV Testing Services We Offer
Highway Condition Surveys
Complete pavement assessment for national highways, state roads, and expressways. Our NSV testing captures roughness, rutting, cracking, and surface distress across your entire road network.
Airport Pavement Testing
Runway, taxiway, and apron condition evaluation following Airport Authority of India guidelines. Our Network Survey Vehicle technology ensures minimal disruption to airport operations.
Pre-Construction Baseline Surveys
Document existing pavement conditions before rehabilitation projects begin. Establish accurate baselines for future performance comparison.
Post-Construction Quality Verification
Verify that newly constructed or rehabilitated pavements meet specified standards. Our NSV testing services provide objective data for project acceptance.
Annual Network Monitoring
Regular condition monitoring programs that track pavement performance over time. Build historical databases to optimize maintenance planning and budgets.
Project Scoping Surveys
Detailed condition assessment to support accurate project scope definition and cost estimation for rehabilitation programs.
What Makes Our NSV Testing Services Different?
High-Speed Data Collection
Our Network Survey Vehicle operates at traffic speeds (50-80 km/hr), surveying hundreds of kilometers per day with zero traffic disruption. This means faster project completion and lower costs compared to traditional manual surveys.
Multi-Parameter Assessment
A single NSV survey captures multiple pavement parameters simultaneously:
• International Roughness Index (IRI) for ride quality
• Rut depth measurements across pavement width
• Comprehensive crack mapping and classification
• Surface distress inventory (potholes, raveling, patches)
• High-definition video documentation
NABL-Accredited Quality
All NSV testing is performed by our NABL-accredited laboratory following ISO/IEC 17025:2017 standards. You receive internationally recognized test results that stand up to audit and regulatory review.
NHAI Compliant
Our testing procedures strictly follow National Highways Authority of India specifications and Ministry of Road Transport and Highways guidelines.
Complete Service Package
From initial survey planning through final reporting, we handle every aspect. You get comprehensive deliverables including condition reports, GIS maps, video documentation, and maintenance recommendations.
NSV Testing Technology and Equipment
Our specialized Network Survey Vehicle features state-of-the-art instrumentation:
Laser Profilometers
Multiple high-precision laser sensors measure pavement surface profile with millimeter accuracy, automatically calculating IRI values that indicate ride quality and pavement serviceability.
High-Definition Cameras
360-degree camera systems capture detailed imagery of the pavement surface. Advanced image processing software identifies and classifies cracks, potholes, and other distresses.
Transverse Profiling System
Laser-based sensors measure rutting depth across the full pavement width, detecting structural deformation in wheel paths that indicates load-related distress.
GPS Geo-Referencing
High-accuracy GPS systems tag every measurement with precise location coordinates, enabling detailed mapping and GIS integration.
Real-Time Processing
Onboard computers process data during the survey, providing immediate quality assurance and preliminary condition assessment.
What You Get: NSV Testing Deliverables
Every NSV testing project includes comprehensive documentation:
Detailed Condition Report
Complete analysis with IRI values, distress quantities, and Pavement Condition Index (PCI) scores for each surveyed section. Reports follow NHAI format requirements.
Interactive GIS Maps
Digital maps showing the location and severity of all identified distresses. Export to your existing GIS platform or use our web-based viewer.
Video Log
High-resolution video footage of the entire surveyed length provides visual evidence and allows remote inspection of pavement conditions.
Maintenance Prioritization
Data-driven recommendations identifying which sections need immediate attention versus routine maintenance. Helps optimize limited budgets.
Remaining Service Life Analysis
Predictive modeling estimates how long pavements will perform adequately before requiring major rehabilitation.
Raw Data Files
Complete datasets in standard formats compatible with pavement management systems and analysis software.

Benefits of Professional NSV Testing Services
Objective Decision-Making
Eliminate guesswork with accurate, repeatable measurements. Automated data collection removes subjective judgment from condition assessment.
Cost Optimization
Identify maintenance needs before they become expensive rehabilitation projects. Target interventions where they’re needed most.
Safety First
NSV testing at traffic speeds eliminates dangerous work zones and protects survey crews from traffic exposure.
Comprehensive Coverage
Survey your entire road network systematically. Don’t miss critical distresses that develop between inspected sections.
Historical Performance Tracking
Build condition databases that reveal performance trends. Understand which pavement types and treatments deliver best value.
Regulatory Compliance
Meet NHAI monitoring requirements and demonstrate responsible asset stewardship to funding agencies and stakeholders.
Our NSV Testing Process
Step 1: Project Planning
We discuss your objectives, review the road network, and develop a customized survey plan including sections to be tested, parameters to measure, and reporting requirements.
Step 2: Site Mobilization
Our team mobilizes the Network Survey Vehicle to your location. We conduct equipment calibration and coordinate with traffic management as needed.
Step 3: Field Survey
The NSV survey is conducted at traffic speeds with continuous data collection. Real-time quality checks ensure data integrity during fieldwork.
Step 4: Data Processing
Our engineers process the survey data, classify distresses, calculate condition indices, and generate GIS maps showing pavement conditions.
Step 5: Reporting
You receive comprehensive reports with condition assessment, maintenance recommendations, and budget estimates for rehabilitation needs.
Step 6: Presentation
We present findings to your team, answer questions, and provide technical support for implementing recommendations.

Frequently Asked Questions
How long does an NSV survey take?
Survey speed is 50-80 km/hr, so a 100 km section typically takes 2-3 hours of field time. Report delivery is 7-10 business days after field completion.
Do you need lane closures?
No. NSV testing survey is conducted at traffic speeds in normal traffic flow. No lane closures or traffic control required.
What road types can you survey?
We survey highways, expressways, urban roads, rural roads, and airport pavements. Both asphalt and concrete surfaces.
Is the data compatible with our PMS?
Yes. We provide data in standard formats (CSV, shapefile, etc.) compatible with most pavement management systems.
How often should we conduct NSV surveys?
NHAI recommends annual surveys for high-traffic corridors. Lower-volume roads may be surveyed every 2-3 years.
