Pavement investigation is a systematic process used to assess the condition, performance, and structural integrity of paved surfaces, such as roads, highways, and parking lots. It involves a series of tests, measurements, and evaluations to identify distress, defects, and deterioration in the pavement, as well as to determine the underlying causes and extent of damage.

Objectives

The primary objectives of pavement investigation are to evaluate the condition of existing pavements, identify maintenance and rehabilitation needs, prioritize repair strategies, and optimize pavement management decisions. Various techniques and methods are employed during pavement investigation, including visual inspection, pavement distress surveys, pavement deflection testing, coring and sampling, and laboratory analysis of pavement materials.

The findings of the pavement investigation provide valuable data and insights for asset management, pavement design, maintenance planning, and budget allocation, ultimately contributing to the safe, efficient, and cost-effective management of transportation infrastructure.
