TL;DR: According to the literature review, this paper confirms optimization can effectively assist DM in IAM and a wide range of optimization methods are applicable to assist a variety of DM problems.
Abstract: Infrastructure assets, serving everyone’s daily life, are an essential foundation of any society. Their management faces a wide range of challenges. Hence optimization methods are increasingly applied to assist making management decisions in infrastructure asset management (IAM). A large number of articles apply a broad range of optimization methods in their decision making (DM) and achieve great results. However, they mainly focus on individual methods and a comprehensive knowledge, given the broad range of optimization methods, is hardly discussed. Hence it is valuable to analyze and graphically present the existing knowledge on this subject. This paper, based on a total of 337 articles, provides an overall review of the applications of optimization when making management decisions in IAM, with the intension of enhancing the optimization application and method selection and guiding the future research in this field. More specifically, this paper introduces the application process of optimization when assisting DM in IAM, summarizes the previous application research, and discusses the popular optimization methods applied in DM in IAM. According to the literature review, this paper confirms optimization can effectively assist DM in IAM and a wide range of optimization methods are applicable to assist a variety of DM problems. The recommendations on the applications and selection of optimization methods in the context of IAM are also made to facilitate the applications.

TL;DR: In this paper, the data collected under the R-6 research project of the Ministry of Surface Transport, India, has been used to develop prediction models and growth curves for rebound deflection, rut depth, and crack area of pavements considering two types of surfacing: BM (bituminous macadam) + PC (premix carpet) and BM + AC (asphaltic concrete), commonly practiced in India.
Abstract: Due to the combined influence of traffic loading and environment, the structural condition of pavement deteriorates with time. Studies on structural damage, which usually results in functional deterioration, is important for the highway engineer to plan the maintenance/strengthening strategies to extend the life of pavements. In the present investigation, the data collected under the R-6 research project of the Ministry of Surface Transport, India, has been used to develop prediction models and growth curves for rebound deflection, rut depth, and crack area of pavements considering two types of surfacing: BM (bituminous macadam) + PC (premix carpet) and BM + AC (asphaltic concrete), commonly practiced in India. The performance of the pavements were studied and comparative analysis was made in terms of growth in deflection, rut depth, and crack area. An attempt has been made to develop failure envelopes based on selected critical rut depth criteria. The results are useful to decide the timing for maintenance/rehabilitation programs.

TL;DR: Numerical examples are presented to illustrate the applications of the program to obtain solutions for three pavement management problems involving different pavement network objective functions and system parameters.
Abstract: The realization of full advantages of pavement management system (PMS) implementation at the network level requires that an optimization analysis be carried out to achieve an optimal programming of pavement activities over a multi-year planning horizon. This paper describes the development of a computer model based on genetic algorithms to solve the network level pavement management programming problem. Numerical examples are presented to illustrate the applications of the program to obtain solutions for three pavement management problems involving different pavement network objective functions and system parameters. Through these examples, the potential uses of the model are highlighted.

TL;DR: The long-term performance of FLEXIBLE PAVEMENTs can be demonstrated by the MAGNITUDE of the TRANSIENT DEFLECTIONS WHICH OCCUR under TRAFFIC as mentioned in this paper.
Abstract: THE LONG-TERM PERFORMANCE OF FLEXIBLE PAVEMENTS CAN BE DETERMINED BY THE MAGNITUDE OF THE TRANSIENT DEFLECTIONS WHICH OCCUR UNDER TRAFFIC. A CONTINUOUS PROGRAM OF DEFLECTION MEASUREMENTS EXTENDING OVER FIFTEEN YEARS HAS BEEN CARRIED OUT THROUGH FULL-SCALE ROAD EXPERIMENTS. OVER 300 EXPERIMENTAL SECTIONS AND, IN ADDITION, 30 LENGHTS OF MAJOR ROAD WHOSE CONSTRUCTION IS OF PARTICULAR INTEREST HAVE BEEN TESTED ANNUALLY WITH THE BENKELMAN DEFLECTION BEAM UNDER A WHEEL-LOAD OF 3175 KG (7000 LB). THE MEASURED DEFLECTIONS HAVE BEEN CORRECTED FOR THE INFLUENCE OF TEMPERATURE ON THE STIFFNESS OF THE BITUMINOUS COMPONENTS, AND THESE STANDARD DEFLECTIONS AT 20 DEGREES C HAVE BEEN RELATED: (A) TO THE AGE OF THE ROAD EXPRESSED IN TERMS OF THE CUMULATIVE TOTAL OF EQUIVALENT STANDARD 8200 KG (18,000 LB) AXLE LOADS CARRIED; AND (B) TO THE CONDITION OF THE PAVEMENT IN TERMS OF RUTTING AND CRACKING. THE DEFLECTION HISTORIES THUS DERIVED ENABLE THE DEVELOPMENT OF CRITICAL CONDITIONS WITHIN THE PAVEMENT WHEN STRENGTHENING OF THE ROAD WOULD BE MOST APPROPRIATE, TO BE RELATED TO DEFLECTION BEHAVIOR UNDER TRAFFIC. OVERLAYS HAVE BEEN APPLIED TO CERTAIN FULL-SCALE ROAD EXPERIMENTS AS THEY HAVE BEEN RETIRED FROM SERVICE AND DEFLECTION STUDIES HAVE BEEN CONTINUED. THE BEHAVIOR OF OVERLAYS LAID TO STRENGTHEN NORMAL ROADS IN BEING SIMILARLY STUDIED. DEFLECTION HISTORIES OF OVERLAID PAVEMENTS HAVE BEEN USED TO PREPARE RECOMMENDATIONS FOR OVERLAY THICKNESSES TO ACHIEVE ANY REQUIRED EXTENSION OF PAVEMENT LIFE. THE IMPLEMENTATION OF RECOMMENDATIONS FOR PAVEMENT STRENGTHENING IS CONSIDERED. /AUTHOR/
