Abstract— Bridges as one of the infrastructure that plays a role in supporting ground transportation, during it service will experience a decrease in conditions caused by the influence of traffic loads, weather effects, environmental influences or other influences. To eliminate the interference required maintenance. A building maintenance including a bridge is preceded by a condition checking activity, and subsequent assessment of conditions. During this examination and assessment of the condition of the bridge refers to the method of inspection and assessment of the conditions set in Bridge Management System (BMS) 1993. There are still weaknesses in the assessment of conditions with Bina Marga BMS caused by the absence of methods of assessing the condition of prestressed concrete bridges. This research is a development of BMS condition assessment, to be used as an assessment of prestressed concrete bridge condition. The object of this research is focused on prestressed precast concrete bridge, namely Kiaracondong Bridge (Bandung) and Cimindi bridge (Cimahi) West Java. The method of assessing the condition undertaken is the examination of damage to the bridge components (physical indicator) through visual inspection, not equipped with destructive and non destructive testing (advanced stage of inspection). Assessment of the conditions developed is the assessment of conditions on the security aspects of the structure and aspects of traffic convenience, where the structure security aspect is the multiplication of the condition of the main part of the building over the bridge. After doing research it can be seen that Cimindi bridge condition value is 3,5-4,25 (need monitoring) and Kiaracondong bridge (very good). The deficiency in the method of assessing the condition in this study is that the assessment of the condition of the bridge is done visually only, so it can not predict the damage to the prestressed concrete components inside. Further examination is required after examination and assessment of this condition is done especially when it is found suspicious things.Keywords: Bridge Management System; Assessment of bridge condition; Prestressed Concrete

One of the efforts in bridge maintenance is by conducting a preliminary assessment with a visual assessment. Growth in the number of vehicles each time will result in a risk of decreasing the capacity of the bridge and its age. Post-construction and maintenance is also a major requirement in infrastructure. This is often ruled out causing the bridge's function and performance to decline and ultimately cause damage. Siliti Bridge is a concrete bridge located in North Bungku Morowali, Sulawesi Tengah. This bridge gets special attention due to quite severe conditions. The purpose of the inspection on the Siliti Bridge is to get its condition visually and determine the estimated age of the remaining bridge which will be capital for further inspection. Bridge Management System (BMS) is a system of assesment to know the existing condition of each element of the bridge. The condition value of the bridge is needed to calculate its remaining life. Based on evaluations conducted in 2017, the value of the Siliti Bridge using the BMS standard is 3 (Damaged). The remaining age of the Siliti Bridge is 8 years.

Accurate and reliable deterioration rate estimates for concrete bridge decks are an important part of the overall bridge condition assessment. The main objective of this paper is to determine the time in condition ratings (TICRs) of concrete bridge decks and assess the impact of average daily traffic (ADT), age, and deck area on the bridge deck condition. Condition ratings of bridge decks over 24 years for Michigan state were collected from the National Bridge Inventory (NBI) data. The Anderson-Darling statistical test was used to evaluate and rank five practical probability distribution functions to select the best fit for Michigan state data. The results indicate that the best statistical model for Michigan state data is the lognormal function. It was illustrated that the TICR decreases when the condition rating decreases. When a concrete bridge deck condition is rated at 8, it can take 11.29 years to drop to the lower rating of 7. However, when the concrete bridge deck condition is rated at 4, it may take 6.64 years to drop to the lower condition rating of 3. It was also observed that on average, bridge decks in Michigan stay much longer than the typical inspection interval (i.e., 2 years), suggesting that inspection intervals can be longer than 2 years for bridges in good condition ranges. The results also show that ADT, age, and deck area are important factors in the deterioration rates of concrete bridge decks.

A significant part of Ukrainian bridges on public roads is operated for more than 30 years (94 %). At the same time, the traffic volume and the weight of vehicles has increased significantly. Insufficient level of bridges maintenance funding leads to the deterioration of their technical state. The ways to ensure reliable and safe operation of bridges are considered. The procedure for determining the predicted operational status of the elements and the bridge in general, which has a scientific novelty, is proposed. In the software complex, Analytical Expert Bridges Management System (AESUM), is a function that allows tracking the changes in the operational status of bridges both in Ukraine and in each region separately. The given algorithm of the procedure for determining the predicted state of the bridge using a degradation model is described using the Nassie-Schneidermann diagram. The model of the degradation of the bridge performance which is adopted in Ukraine as a normative one, and the algorithm for its adaptation to the AESUM program complex with the function to ensure the probabilistic predicted operating condition of the bridges in the automatic mode is presented. This makes it possible, even in case of unsatisfactory performance of surveys, to have the predicted lifetime of bridges at the required time. For each bridge element it is possible to determine the residual time of operation that will allow predict the state of the elements of the structure for a certain period of time in the future. Significant interest for specialists calls for the approaches to the development of orientated perspective plans for bridge inspection and monitoring of changes in the operational status of bridges for 2009-2018 in Ukraine. For the analysis of the state of the bridge economy, the information is available on the distribution of bridges by operating state related to the administrative significance of roads, by road categories and by materials of the structures. Determining the operating state of the bridge is an important condition for making the qualified decisions as regards its maintenance. The Analytical Expert Bridges Management System (AESUM) which is implemented in Ukraine, stores the data on the monitoring the status of bridges and performs the necessary procedures to maintain them in a reliable and safe operating condition. An important result of the work is the ability to determine the distribution of bridges on the public roads of Ukraine, according to operating conditions established in the program complex of AESUM, which is presented in accordance with the data of the current year. In conditions of limited funding and in case of unsatisfactory performance of surveys, it is possible to make the reasonable management decisions regarding the repair and the reconstruction of bridges. Keywords: bridge management system, operating condition, predicted operating condition, model of degradation, bridge survey plan, highway bridge.
