Highway Pavement Condition Evaluation PQI (JTG 5210-2018)

Problem

Highway pavement condition evaluation under JTG 5210-2018 requires computing PCI, RQI, RDI, SRI, and PBI, then applying PQI weights by pavement type and road class. Manual workflows can miss items, misapply weights, or include PSSI in PQI even when it should not participate.

How It Works

• Input parsing: reads route name, station segment, pavement type, road class, test length, IRI, rut depth, skid resistance, and damage areas from CSV.
• Index calculation: computes PCI, RQI, and SRI using standard formulas; high-speed or Class 1 asphalt pavement can include RDI and PBI, while cement pavement excludes non-applicable items.
• Rating and advice: outputs the PQI score, weight settings, itemized calculations, an ASCII bar chart, and maintenance actions such as routine maintenance, preventive maintenance, medium repair, or major repair.

Boundaries

Useful when inspection data exists and a standards-based report is needed. Results depend on input quality; incorrect pavement type, road class, or damage categories change PQI weighting and sub-indices. It does not replace field testing, engineering review, or formal acceptance conclusions.
