The second method our firm uses is automated data collection, for large linear network assessments. For this type of inspection, PEA teams with our data collection partner, GIE Technologies.

The pavement network is divided into manageable units called, “segments” using determining factors such as pavement type, traffic, history, smallest repair unit desired, etc. GIE uses a specially equipped vehicle, which is driven over the pavement network to collect the distress data.

Data is collected with the use of cameras, profiling devices and laser sensors. The data is then downloaded to a computer at GIE’s corporate office for processing. The processed data is managed with a PMS (Pavement Management System).

In order to maximize the return on investment for a pavement management program, it must remain current. PEA will maintain your database by incorporating new construction/revisions that impact pavement condition and/or use. Professional Engineering Associates recommends a reassessment every three years to keep your pavement data current.

Pavement Assessments are used to identify and inspect the pavement to be included in the pavement management program or individual facility report. PEA assesses pavement via one of two methods.

The first method begins with a visual inspection, performed by walking the area in question, noting distresses and entering this information into a database.

During the assessment, the paved areas are divided into sections and classified by different categories, such as condition, use, priority and material (i.e. concrete or asphalt). Professional Engineering Associates uses this type of survey for small linear pavement networks (Roads), and  non-linear pavement networks (Parking Lots).
