MoDOT Pavement Preservation Research Program Volume VI, Pavement Treatment Trigger Tables/Decision Trees and Treatment Candidate Selection Process

The objective of Task 5 was the development of pavement treatment trigger tables and the treatment candidate selection process. The input to the trigger tables entails such factors as an overall condition indicator, smoothness, individual distress types-extent severity (e.g. thermal cracking, block cracking, fatigue cracking, longitudinal cold joint cracking, joint reflective cracking, longitudinal wheel path cracking, longitudinal edge breakup, patches and potholes, raveling, polishing, stable rutting, corrugations and shoving, bumps and sags, bleeding, D-cracking, pop-outs, spalling, corner cracks, faulting), pavement type, history of treatment, and some measure of traffic, through a surrogate such as Surface Age. Output is one or more potential appropriate treatments, which would consider pavement condition, traffic, climate (which affects construction timing and treatment performance), work zone duration (e.g. traffic control issues), time of year construction, construction quality risk, availability of quality contractors and quality materials, longevity of treatment, and availability of funding. Trigger tables include preservation treatments (chip seals, micro-surfacing, slurry seals, ultrathin bonded asphalt wearing surface (UBAWS), crack sealing, crack filling, thin overlays, mill and fill, profile milling, hot in-place recycling, cold in-place recycling, diamond grinding, whitetopping, load transfer retrofit and joint repair, and partial/ full depth repair).
