Pavement Condition Data Collection
Millions of miles of pavement and years of experience has made Pathway Services the industry leader in pavement condition collection services in the United States and beyond. Our automated pavement condition surveys are designed to adapt to each client’s unique requirements while maintaining set standards such as HPMS reporting and more.
Our 3D subsystems, both the legacy Pathway 3D and second-generation 3D- PAS, capture a linescan-like image while also storing a depth value for every collected pixel, resulting in both a photo and scan of the road to isolate differences in height for surface characteristics. The finished product creates a continuous 3D scan of the road that our software solutions then analyze with automated tools for cracking, rutting, faulting, and many other distresses. This system is used by more than 50% of USDOTs to collect these data types and exceeds all technical specifications such as AASTHO R36-13, PP 69, and PP 70.

LiDAR Data Collection
Pathway Services provides LiDAR mobile mapping data collection services using the highest quality LiDAR scanner and an integrated camera array for parallax-free colorization. The high performance of this survey grade single-scanner LIDAR subsystem provides the most precise and accurate data without the need for bore sighting calibration and limited post-processing requirements.
For efficiency and flexibility, we collect HD LiDAR as a subsystem integrated on the PathRunner along with typical network collection, or as a dedicated mobile LiDAR unit for leaf-off season or specialty projects. Inherent to our LiDAR data collection services are processing, compressing, and hosting the point cloud data for a simplified turn-key operation. HD LiDAR scanning units can include dedicated cameras for point cloud colorization, enhancing data manipulation to improve analysis and extraction processes. Once collected, our clients own the point cloud data for viewing and continued analysis in our web-based software, PathPoints, or to integrate into their existing platforms via standardized file formats.

Asset Extraction
Let us inventory your asset infrastructure from the ground up, capturing each roadway feature spatially, at a moment in time, and with full attribution for your maintenance, modeling, planning, and safety analysis needs.
Network-level asset inventory extraction can be a daunting prospect to any agency, which is why Pathway Services has dedicated teams and customized tools developed over many years to make asset collection quick and thorough. We provide you with over 35 unique asset guides to start each of your asset inventory projects with proven extraction guidelines and the premier image sampling to build customized data dictionaries for final reporting formats. Along the way, we will use your specific feature types and routing methods to design a scope that meets all department needs and will support DQMP references for QA purposes. At Pathway Services, we provide the most comprehensive asset data to our clients. The extraction technology may rely on our HD camera systems or colorized HD LiDAR scanning units. We work with each client pr asset type to determine a methodology that best suites the accuracy and attribution needs for the project. Automated and semi-automated tools make extraction reliable and repeatable. Reporting formats adapt to each project with shape files, KMZ, .csv, .xsls, and .txt files all standard file types available for export.

Macrotexture Data Collection
Macrotexture Data Collection provides identification of changes in pavement surface height larger than 0.5mm on a network level. When combined with other data sets, macrotexture data collection can provide valuable pavement texture information with the intention of identifying areas with the potential for hydroplaning.
- ASTM E1845-15 compliant
- MEASURED SEGMENT BASELENGTH: 100m
- X RESOLUTION: 0.2mm maximum
- Y RESOLUTION: 0.02mm maximum
- Z RESOLUTION: 10m minimum
- HARDWARE: GoCator 2300 sensor scans 100mm line of data
Texture Signature Data Collection
Pathway Services has pioneered a NEW, ground-breaking high-density 3-zone Texture Signature system that is changing the way the industry evaluates pavement texture. Pavement signatures combined with road geometries will help redefine “safe” and potentially help reduce texture-related incidents on your network.
Surface height changes calculated at the microtexture level in the LWP, Center, and RWP are used to determine pavement deterioration by zone and using year-over-year analysis. Texture profiles and road geometry combine to flag network locations, presenting potential texture-related risk areas considering standard tire composition and performance.
- Texture Signature data is 5000x more dense than ASTM E1845 requirements
- Texture Signature data resolution is 5 times greater than current macrotexture systems
- Texture Signature Number is plotted data spatially, providing the ability to compare against other relevant data sets (i.e., curvature, roadway geometry, and vehicle speed) for roadway safety analysis
- Custom reports generated at any interval to as small as 6 feet
- Capable of simultaneous network collection with all other PathRunner subsystem data
- SCAN FREQUENCY: 3kHz
- X RESOLUTION: 0.2 mm
- Y RESOLUTION: 0.02mm
- 500 points per 100 mm profile
- Outputs a Texture Signature Performance Index (TSPI) value, MPD, and MTD
Pavement Condition Reporting
HPMS pavement condition annual reports and other state-requested customizations for statewide pavement condition management are our specialty. Pathway Services supports 1/2 of the nation by providing simple interface solutions and single-click exports to non-proprietary .csv files.
PathRunners are equipped with the latest technology, integrated for continuous data collection and network-level roadway analysis. Onboard assistance features in each PathRunner enhance data quality by alerting teams of potential data quality concerns, GPS location notifications, of subsystems status in advance of critical errors, and numerous other safety reminders. The voice-animated system promotes in-field efficiencies and lower re-collection percentages in each project.
While collecting an agency’s network, our team will provide:
- Daily Project Tracking Maps
- Weekly Progress Reports
- Weather Advisories
- GPS Route Corrections
See our “Technical” page for subsystem information.
Skid Resistance Data Collection
When it comes to roadway safety, the value of understanding resistance to skid cannot be underestimated. Collecting skid data is time-consuming and demanding, so why not let us collect the data for you? We offer statewide skid data collection so you can make the decisions necessary to keep your motorists safe and on the road.
Quantifying skid resistance considers the interaction between a vehicle’s tire and the pavement on both a macrotexture (large-scale texture defining the potential for the redistribution of water from the surface) and microtexture (small-scale texture defining the contact that exists between the tire and the pavement). Year-over-year or seasonal analysis can provide information with regard to pavement water and aggregate polishing and the effects of climate on tire and pavement composition.
- Locked Wheel testing on dry pavement
- AASHTO M261 and ASTM E501
- 40 mph testing speed
Ground Penetrating Radar Data Collection
Pathway Services offers mobile Ground Penetrating Radar surveys, capturing below-ground feature density variance to identify pavement layer thickness, roadway asset infrastructure, and sub-surface anomalies.
GPR is a safe, non-destructive and cost-effective way to map subsurface characteristics of the road, detecting metal and non-metal objects, voids and other underground irregularities. Reflected high-frequency radio frequencies are evaluated to identify and measure dimensions, depth and thickness of rebar and dowel rods, public utilities, pipes, void spaces and sinkholes and more.
