**Ground penetrating radar** provides a fast, non-destructive method for evaluating pavement conditions and supporting data-driven maintenance decisions. This guide explains how GPR for pavement inspection measures layer thickness, evaluates base and subgrade conditions, and detects hidden defects such as stripping, delamination, moisture, and subsurface voids. It also covers bridge deck assessment, buried utility detection, antenna frequency selection, data interpretation, calibration, and cost benefits. By combining continuous subsurface data with targeted coring, engineers can improve rehabilitation planning, reduce unnecessary testing, and manage pavement assets more efficiently.

Choosing between a GPR array system and portable GPR depends on survey size, site access, required data density, and processing capabilities. This guide compares both ground penetrating radar solutions across scanning speed, coverage, resolution, depth, maneuverability, deployment, and data processing. Portable GPR is well suited for localized utility locating and confined spaces, while GPR array systems deliver high-speed, dense 3D data for large-scale infrastructure surveys. Understanding these differences helps engineering and survey teams select the right GPR equipment for efficient and accurate subsurface investigations.
