Abstract

Road damage is a serious problem because it often occurs everywhere. Damage to the road surface, such as potholes, often disrupts land transportation, and can even cause accidents. With the automatic detection of road damage types, it can simplify the process of classifying the types of road damage by using images from the results of the classification system which can be used as supporting information in calculating road repairs. In this study, to identify road damage types by images, the active contour model segmentation technique is used based on the level set and then classified by the support vector machine method. Based on the test results, using 58 data sets with 12 types of road damage, the accuracy of this method is 87.93%.

Abstract

The standard code of planning and loading bridges in Indonesia has undergone several changes, especially in the earthquake load planning aspect, with the latest changes in 2016, namely SNI 2833:2016 and SNI 1725:2016. With this change in standard codes, bridges that were already operating in Indonesia before 2016 needed to be evaluated on their structural performance. In this paper, evaluation was conducted on a pre-stressed bridge with voided slab type, such as Bridge 5 Cawang Interchange at Jakarta Intra Urban Tollway which has been built since 1987. The evaluation results howed that the axial-bending capacity of the bridge pier elements was not able to carry loads with the latest standard codes in extreme boundary conditions. In addition, the required area of confinement reinforcement on the bridge pier elements does not meet the minimum requirements. Furthermore, evaluation of bridge structure performance is carried out by using static pushover analysis (NSPA) on the pier P3 element bridge loading toward longitudinal direction, resulting P3 performance in Operational - Life Safety (O-LS) conditions reach a drift of 1.56%. Ultimately, when the structural retrofitting model is applied to the P3 pier element with RC-jacketing fc' 25 MPa with a thickness of 100 mm and additional longitudinal reinforcement of 72 D29, the P3 capacity is expected to increase by 49% from the initial capacity and the performance level will decrease to the Operational level (O) with a drift of 1%

Abstract

Structural flexible pavement evaluation can be performed by measuring vertical deflection on the pavement surface. FWD (Falling Weight Deflectometer) is one of the available apparatus for this purpose. There are several different methods to analyze the deflections such as backcalculation, AASHTO 1993, and Pedoman 2005. Remaining life of the existing pavement on Pedoman 2005 based on solely the deflection at the center of the loading plated at standard pavement temperature (35oC), standard loading (4.08 tons), and depends on water ground level – without evaluating structural layers moduli. On the other hand, AASHTO method based on a deflection relatively far from the center, and a deflection at the center of the loading plate at standard pavement temperature (68oF). The AASHTO evaluates resilient modulus of subgrade, and effective modulus of pavement structure above the subgrade – and later the pavement remaining life. Other than the previous methods, output of backcalculation method are every and each pavement layers moduli that has been modelled. The remaining life is determined by using AASHTO relationship number of load repetitions and effective structural number. As the results of MICHBACK subgrade resilient modulus is greater (114.6%) than the AASHTO. Effective structural number of MICHBACK is less (92.32%) than the AASHTO. The combined differences on subgrade resilient modulus dan effective structural number on remaining life of the MICHBACK is 70.6% of the AASHTO. While remaining life of Pedoman 2005 is 125.8% of MICHBACK. When results of MICHBACK backcalculation is considered as referenced, calibration factor for remaining life of AASHTO is 0.706, and Pedoman is 0.78

Abstract

Ravelling is road damage that occurs when the bond between aggregate and asphalt has been lost. One of the factors of ravelling damage is caused by the decreasing value of cohesion and adhesion. Therefore, the material factor becomes one of the parameters in increasing the value of cohesion and adhesion to asphalt. To improve material quality as well as an effort to reduce environmental pollution, polypropylene (PP) plastic waste is used in asphalt concrete wearing course mixtures. This study aims to determine the effect of adding polypropylene (PP) plastic waste to Marshall characteristics and revelling resistance seen from the VIM value and abrasion value with variations in polypropylene (PP) waste content as much as 0%, 2%, 4%, and 6% of the weight of the asphalt. Marshall test results show that the values ​​of stability, VMA, and MQ tend to increase, while the values ​​of flow, VIM and VFA tend to decrease with the increase in the percentage of polypropylene (PP) plastic waste content in the asphalt. As for the reMults of the abrasion value with a simple ravelling modification tool, it shows that the higher the percentage of polypropylene (PP) plastic waste in the asphalt, the smaller the VIM and abrasion value. It can be concluded that the addition of polypropylene (PP) plastic waste can improve the performance of the mixture against ravelling resistance seen from the VIM value on the Marshall parameter and the abrasion value of the ravelling test.

Abstract

As the second largest natural rubber producer in the world, each year Indonesia produces 3.5 million tons natural rubber which most of it (85%) is sold (exported) to the international market. Currently its price in international markets is fall, of course Indonesia was greatly affected. In response to this condition, the government encourages the use of local natural rubber, including as an additive of asphalt to produce rubberized asphalt as an asphalt pavement binder. However rubberized asphalt products, produced using current technologies, are still inferior in terms of quality and price when compared to polymer modified asphalt which used imported synthetic polymer (SBS). In response to this, a new technology local natural rubber as a binder of hot mix asphalt was developed. The technology latex (which cheapest natural rubber) to modify petroleum asphalt in hot mix asphalt mixture when mixed in pug mill in AMP (Asphalt Mixing Plan). This study was carried out in the laboratory by testing the properties of asphalt and asphalt mixtures based on SKh-1.6.26 (Ditjen Bina Marga, 2018), then compared with current technologies rubberized asphalt and synthetic polymer modified asphalt. In this way, at a dry rubber content of 4.2% to asphalt, in addition to a cheaper price of 22%-25%, the quality of the rubberized asphalt in the mixture and the quality of its hot mix asphalt produced are also higher.

Abstract

This paper presents the development of road assessment attributes for the calculating Road Protector Scores (RPS) or Star Rating Scores (SRS) model for Indonesia’s national roads derived from the perspective of four-wheeled or more motorized vehicle drivers. Based on the study of traffic accident characteristics from a total of 283,518 accidents, two new accident types are considered significant as parameters for calculating SRS. These accidents are front-rear collision and front-side collision, and they are the top of highest types of accidents on Indonesia’s national roads. The inclusion of the two types of accidents is hypothesized to provide differences between the attributes in the SRS model for Indonesia’s national roads and the SRS developed by iRAP. Benchmarking and studies based on accident characteristics of the attributes have resulted 51 items while the SRS iRAP model has 31 items. A quadrant analysis by using Importance and Performance Analysis (IPA) method, have shown that there are 43 attributes that can be divided into six parameters of the National Road SRS model. Sign test using a binomial table that has use in this research also proves that there is a significant difference between the numbers of attributes of the two road assessment attributes of SRS iRAP and SRS National Road models. The difference in attributes in the two SRS models is shown by 17 different and completely new road attributes from the previous SRS models. This result implies that the RPS attributes in the iRAP model must be modified according to the dominant types of accidents if it is to be applied in Indonesia. Theferefore, an SRS model developed for Indonesia's national roads needs to integrate these attributes.

Abstract

Bridges usually have massive concrete structures. The massive concrete will cause temperature on the concrete to be overheated when concrete hardening. The impact from this excess heat results in imperfect hydration and thermal crack which can affect the compressive strength of concrete. Simpang Susun Airmadidi Toll Access Bridge has a pile cap and pier structure with a width > 2 meters so that it can be categorized as mass concrete. To reduce heat arising from concrete hydration, additional materials are needed. The supplementary cementitious material that can be used in concrete mixed according to General Specifications of Road and Bridge Construction Works are materials in the form by minerals or waste materials such as fly ash, pozzolan and silica fume. Simpang Susun Airmadidi Toll Access Bridge project is used fly ash. The study was conducted by reading the temperature rise in two specimens with different concrete mixed. Test object 1 using 380 kg pure OPC cement and Test object 2 using 310 kg OPC cement and 100 kg fly ash F class per m3 of concrete. From the evaluation results it can be concluded that replacement of 24,4% cement using fly ash reducing maximum temperature of concrete from 84.4°C to 71.3°C or decreasing about 13.1°C. Thus fly ash can be an alternative environmentally friendly construction material.
