Maintenance
Published in Connie Kelly Tang, Lei Zhang, Principles and Practices of Transportation Planning and Engineering, 2021
A pavement management system is a decision-making tool where both project (e.g., a specific road) and system (e.g., a group of roads) level decisions can be made regarding when, what action, and how much investment should be delivered to a road or a group of roads ensuring an optimum pavement condition. In other words, a pavement management system facilitates the optimum distribution of funds to different roadways to achieve the optimum pavement condition for the entire roadway system.

An effective Pavement Maintenance and Management System (PMMS) requires the prioritisation of the road stretches for logical disbursement of budget. In a Pavement Management System, prioritisation of road sections plays an important role, especially when budget available for road maintenance is limited. Though the optimisation of maintenance strategies for road network is considered to be a complete and an ultimate solution in PMMS, many a time it can be an impractical solution for rural roads due to the limitation on the budget. The assessment of pavement condition is mandatory for the prioritisation process and it necessitates the measurement of various distress parameters with respect to their extent and severity. Though the extent of distresses can be measured accurately, the severity of distresses has unavoidable uncertainty associated with it. Hence Fuzzy Multi Criteria Decision Making (FMCDM) approach is a better option wherein the fuzzy logic is being applied to only those parameters which is predominantly uncertain in nature. The roughness on the study roads was found to be fairly high and it has significant influence on the user perspective about the condition of pavement. Hence in the present study, apart from the functional distresses, roughness of the road surface which is another parameter indicating riding comfort was also included as a parameter to define the condition of the pavement. Extent of distresses and roughness was proposed as a direct parameter and a fuzzy approach was suggested to assess the severity of distresses.

Maintenance and rehabilitation (M&R) of pavements should ideally be conducted through the use of pavement management, which can ensure the optimum use of tax dollars through the selection and use of the most cost-effective design, construction, and rehabilitation strategy. Pavement management involves all activities regarding the planning, design, construction, maintenance, and rehabilitation of pavements. It is based on the pavement management system (PMS), which consists of a set of tools or methods that help pavement managers to plan for constructing and maintaining highway or airport pavements in a serviceable condition over a given period of time.

In order to keep pavements in appropriate condition, road agencies rely on pavement management systems (PMS). Pavement management is defined as the set of tools or methods that assist decision-makers in finding the optimum strategies for providing, evaluating, and maintaining pavements in a serviceable condition over a time period. PMS is the analysis tool or software program used for generating and analysing the pavement management strategies (AASHTO 2012). Different objectives pursued in PMSs are optimising agency costs, maximising infrastructure performance, arranging priority scheduling, developing pavement deterioration models, and providing appropriate maintenance strategies (Garilli et al. 2021). The first steps towards conducting pavement management are the inspection of pavement condition and development of a database containing pavement information (Peraka and Biligiri 2020, Jana et al. 2022). The database, which is known to be the core and an essential part of PMS, is comprised of five different groups of data: (1) inventory data (pavement sections, road geometrics, and road amenities such as bumps and drainage systems), (2) condition data (roughness, distresses, and skid resistance), (3) design data (pavement design, mix design details, material characteristics, and pavement layers specifications), (4) maintenance history data (previous maintenance timing and methods), and (5) auxiliary data (traffic volume and speed, seasonal correction factors, axle loads, vehicles classification, and vehicle operation costs) (Peraka and Biligiri 2020).

Millions of dollars have been spent on pavement maintenance and rehabilitation (M&R) every year in the United States, but highway infrastructures in many states have deteriorated due to insufficient funding budgets for M&R practices (Geoffroy, 1996). Highway agencies thus emphasise more on M&R strategies effectiveness and lower expenses (Fwa et al., 2000). However, in most current agencies, the selection of M&R strategies either focuses too much on pavement performance and ignores costs, or is based on short-term treatment costs only, or judged by expert experience, which is subjective and not cost-effective over the long-run (Irfan et al., 2009). The limited M&R budget increases the need for improved pavement management methods and comprehensive economic analyses of the alternatives concerned.
Optimisation of pavement maintenance and rehabilitation activities, timing and work zones for short survey sections and multiple distress types

Pavement management covers the processes of data collection, condition assessment and prediction, planning, optimisation and application of maintenance and rehabilitation (M&R) treatments, as well as budgeting. The objective of M&R optimisation is to maximise performance (e.g. network condition), or to minimise agency and user costs, or to minimise risk/environmental impacts by selecting appropriate treatments (decision variables), subject to constraints (e.g. budget). This problem can be formulated for a single road section (single facility), for a travel route consisting of multiple sections, or for the entire network (system) covering all sections and other road assets.
