In addition to mobile LiDAR design-grade mapping and asset management services, G&AI also collects ASTM standardized pavement data used to assess the condition of both asphalt and concrete surfaces. G&AI’s pavement system is approved by the Texas A&M Transportation Institute (TTI) and is equipped with the latest computer, sensor, and video equipment designed to efficiently collect laser data and video images of the roadway surface. The data is collected to provide specific information about roadway distresses and pavement performance with respect to ride quality. Information extracted from asphalt and concrete surface data provide network and project-level condition assessments, performance trend analyses, needs assessments, and program level decision making to both public/private sector entities.
This leading-edge technology uses a 3D camera to capture a laser line as it’s projected over the surface of the pavement and uses the location of this line to measure height deviations of the roadway surface. The height deviations can be plotted and used to calculate rutting on both wheel paths. The camera provides enough data speed to capture several profiles at every inch. Each profile consists of thousands of points across the lane, covering more than an entire lane and providing the ability to discern up to 2mm cracking on the road surface—at highway speeds.
G&AI’s ability to capture both pavement data (ASTM Specifications) and assets simultaneously offers a tremendous savings to our public and private sector clients. G&AI’s “One collection—multiple uses” methodology is the most cost effective infrastructure management solution on the market. Final pavement data can be delivered in geodatabase format or by our web-hosted online viewer allowing the end-user to take existing GIS data and overlay/integrate with the new pavement information.
