“…A wooden disc with a hard rubber surface was used to spread the silica sand until a circular area with a radius of between 5 and 18 cm was achieved ( Figure 3E). Once the circle appeared, its diameter was measured with calipers, and the average depth of macrotexture (H) was calculated according to Equation [3]. This test procedure was conducted four to five times on a single specimen, creating a circle on the central part of the specimen, and a circle in each of its corners.…”

“…Clearly, the main aim of rehabilitation and maintenance programs is to extend the service life of these infrastructures. Thus, highway agencies worldwide are attempting to find the most cost-effective and efficient solutions to achieve this goal (3). Traditionally, dense-graded mixture overlays (with a thickness around 50 mm) have been used as a rehabilitation action for asphalt pavements.…”

Very Thin Asphalt Overlay (VTAO) has been introduced as an alternative to traditional thick overlays, seal coats, and micro-surfacings. Nonetheless, there are some challenges that still remain regarding the application of VTAOs (such as mixture type, cohesiveness, wear resistance, cracking and durability), particularly in heavy traffic urban areas. Therefore, this paper presents an extensive comparative evaluation of the mechanical performance, durability and safety issues (cohesiveness, adhesiveness, ageing, cracking, plastic deformation, permeability, macrotexture, skid and wear resistance, and fuel resistance) of a VTAO (20 mm thick) and a high performance BBTM 11B (35 mm thick), commonly used as an open-graded mixture for pavement overlays. The results demonstrated that VTAO is an appropriate material for urban pavements as it provides good durability and resistance to the propagation of defects. Nonetheless, further studies are required to improve its behavior under distresses related to plastic deformations and safety properties. RESUMEN:Evaluación del comportamiento mecánico de capas bituminosas ultra delgadas como una adecuada estrategia para la rehabilitación de pavimentos urbanos. Las capas bituminosas ultra delgadas para rehabilitación superficial de carreteras son una alternativa a las tradicionales capas asfálticas, riegos bituminosos y micro-aglomerados. No obstante, aún son numerosos los aspectos a estudiar para la generalización de su uso, particularmente en zonas urbanas con elevado tráfico. Así, este artículo recoge un análisis comparativo del comportamiento mecánico, durabilidad y factores de seguridad (evaluando parámetros como cohesividad, adhevisvidad, envejecimiento, fisuración, deformaciones, permeabilidad, macrotextura, y resistencia al deslizamiento, al desgaste y a los combustibles) entre una capa delgada de 20 mm de espesor, y una mezcla discontinua de altas prestaciones (BBTM-11B con 35 mm), comúnmente utilizada en capas de rodadura. Los resultados indican que puede ser una adecuada solución para pavimentos urbanos dada su durabilidad y resistencia a la propagación de fallos. No obstante, se requieren futuros estudios centrados en la mejora de parámetros de seguridad y de su resistencia a las deformaciones permanentes.

Abstract-Naturally, buildings will deteriorate during its life cycle. On the other hand, sustainability of building condition is the main objective of providing service for users. Therefore, building maintenance management should be a priority to achieve that objective. In Indonesia, there are many public buildings with different conditions and some of them are not in optimal conditions demanding urgent maintenance treatment. In addition, limited budget and absence of building maintenance decisionmaking tool are among factors causing unmanaged maintenance activities. Moreover, agencies must allocate maintenance budget and prioritize buildings maintenance manually. This paper proposes an optimization mathematical model which adopts Constraint Programming (CP) formulation to assist in selecting the most cost-effective strategy for particular building and determining budget allocation each year. CP is famous on its flexibility to problem declaration that makes scenario analysis conduct effectively. This CP-based model subjects to budget constraint and required condition level. In this case, budget, maintenance strategy options, building deterioration rate, time period, and minimum acceptable building condition are set. There are four maintenance strategy options available, Light Repair, Rehabilitation, Renovation, and Restoration which have different improvement impact for each strategy. Therefore, a case study is conducted to implement the model which involves 15 buildings in a 10-year time of period and two scenarios are presented in this proposed model. The result shows that the two scenarios allocate annual maintenance budget differently depending on diversities of planner management goals.

“…This combinatorial optimization problem can be solved using either mathematical or heuristic methods. Mathematical methods (including linear, non-linear, integer and dynamic programming) have been applied in previous studies dealing with both bridge (Frangopol and Liu, 2007) and pavement maintenance (de la Garza et al, 2011;Gao et al, 2012;Marzouk et al, 2012). These methods have the advantage of providing optimal solutions for the network as a whole.…”

Abstract. Insufficient investment in the public sector together with inefficient maintenance infrastructure programs lead to high economic costs in the long term. Thus, infrastructure managers need practical tools to maximize the Long-Term Effectiveness (LTE) of maintenance programs. This paper describes an optimization tool based on a hybrid Greedy Randomized Adaptive Search Procedure (GRASP) considering Threshold Accepting (TA) with relaxed constraints. This tool facilitates the design of optimal maintenance programs subject to budgetary and technical restrictions, exploring the effect of different budgetary scenarios on the overall network condition. The optimization tool is applied to a case study demonstrating its efficiency to analyze real data. Optimized maintenance programs are shown to yield LTE 40% higher than the traditional programs based on a reactive strategy. To extend the results obtained in this case study, a set of simulated scenarios, based on the range of values found in the real example, are also optimized. This analysis concludes that this optimization algorithm enhances the allocation of maintenance funds over the one obtained under a traditional reactive strategy. The sensitivity analysis of a range of budgetary scenarios indicates that the funding level in the early years is a driving factor of the LTE of optimal maintenance programs.
