Abstract

This research evaluates the mechanical properties and fracture behaviour of ethylene-vinyl acetate (EVA) polymer-modified warm mix asphalt under the influence of ageing simulated through oven heating at 85oC in two different durations of 2 and 8 days. EVA contents of 4 - 6% of binder weight were employed, and the effect was measured through the semi-circular bending (SCB) test. Volumetric properties measurement showed negligible effect of polymer addition, with the difference in air void ratio ranging from 0.5% to 8% compared to the control mix. Meanwhile, the density and void in mineral aggregate (VMA) differed by a maximum of 2% compared with the control mixture. Moreover, the increase in the heating period was found to enhance the tensile strength, with a maximum difference of 81.72% exhibited by the mix with 0.5% EVA, corresponding to its tensile strength from the 8-day ageing conditioning by 28% larger than the control mix. Moreover, crack resistance and flexibility indexes (CRI and FI) were inversely proportional to the increase of polymer dosages for both 2- and 8-day aged specimens from being 20.5% and 52% to 6.4% and 18.3% larger than the control mixture, respectively, with the 8-day aged specimens having the CRI of 8% larger and FI of 8.7% smaller than the 2-day aged samples, indicating a brittle behaviour in respect to the ageing duration. Conclusively, the heating ageing simulation results in a brittle asphaltic mixture modified with EVA, displayed with higher strength and lower flexibility, particularly at 5% to 6% w/t.

Abstract

 Slope failure is caused by many factors, mainly high rainfall, especially in a tropical country like Indonesia. Many solutions have been expanded to do remediation of slope failure. However, establishing the best solution method is difficult because of many geotechnical challenges and different situations at the site. In addition, fast rate construction in line with a good quality of stability aspect is necessary to be attained. Therefore, a comparative study of two common solution methods, namely conventional cantilever wall and mechanically stabilized earth wall, was conducted to determine the best solution for slope failure remediation in the case studied. The analysis was performed by using a computer software program coded Geo5. A slope failure case in Bali was selected to investigate the performance of both studied methods in meeting all engineering criteria, including bearing capacity, internal stability (overturning and sliding), and global stability. The results show that mechanically stabilized earth wall gives more advantage not only in meeting all criteria but also in providing aesthetic concern and sustainable performance. On the other hand, conventional cantilever walls show a deficiency in global stability that will require pile foundation support or another reinforcement under the base plate, which will automatically increase construction time. The use of computer software will provide a more sophisticated analysis to examine various slope failure remediation methods to establish the most suitable solution for the specific sites. There is still expansive room to be researched in this area.

Abstract

The behavior of prestress pretension beams made of Reactive Powder Concrete (RPC) concrete with compressive strength above 120 MPa included in the Ultra High Performance Concrete (UHPC) classification was investigated to study the mechanical properties of concrete and the performance of prestressed beams against static load tests. The mechanical properties of RPC materials include concrete compressive strength, concrete tensile strength, concrete elastic modulus values and concrete density compared to 70 MPa High Strength Concrete (HSC) concrete. Curing concrete at an early age using high temperature hot steam (steam curing) ensures the development of the compressive strength of concrete. Experimental tests were carried out on 4 pretension beams designed to be used as highway bridge beams, namely beam #1 (30/50-HSC-NF-S); beam #2 (30/50-RPC-F-S); beam #3 (17/50-RPC-NF-S); beam #4 (17/50-RPC-NF-S). The mechanical properties of RPC concrete show superior values compared to HSC concrete. From the results of the static test, only beam #3 (RPC beam which does not use steel fiber in mixing) which shows a value of flexural resistance below the theoretical value due to brittle destruction that occurs in the beam. Steel fiber effectively maintains beam integrity thereby maximizing bending resistance, preventing explosive brittle destruction, and preventing concrete fragmentation during peak loads.

Abstract

The condition of the road pavement is an important aspect in terms of determining road maintenance and repair activities. In order to evaluate the condition of the road pavement, it is first necessary to determine the type of damage, the cause, and the extent of the damage that has occurred. Construction of a road that is not accompanied by good maintenance will cause various kinds of problems. Many district/city road pavements in Central Kalimantan have suffered damage as a result of repeated traffic loads, in line with increasing economic growth in these areas, including one of them on the Pulang Pisau – Pangkoh Road Section as far as ± 57.5 Km which is located in Pulang Pisau Regency, Central Kalimantan Province. So that on this road research will be carried out on the remaining existing road services to be able to provide alternative solutions for handling existing road problems and also budget plans. The method used in this study is using a FWD (Falling Weight Deflextometer) to determine the condition of the road structure. In addition, to find out how to handle it, this study used the 2017 Pavement Design Manual. Comprehensive road survey vehicles typically consist of a FWD mounted on a heavy truck together with a ground-penetrating radar and impact attenuator. The results obtained from this study are the remaining life of the Pulang Pisau – Pangkoh road section of 17% x UR (about 3-4 years). For its handling, it uses a flexible pavement overlay which was previously covered with selected fill and requires a cost of Rp. 243.905.730.000,- or Rp. 6.097.643.250,- per Km.

Abstract

This study discusses geopolymer-reinforced concrete beam's shear strength capacity by experimental observation using high-calcium fly ash as the main binder. This study observed the influence of shear span per effective depth ratio due to the geopolymer concrete beam's shear behavior and strength capacity. Two beams are designed to have diagonal tensile cracks; hence the shear failure state could be obtained. Each beam has similar properties by 150 mm in width, 250 mm in height, 1800 mm in length, 2D16 as the flexure bar reinforcement, and stirrups of Ø6-250 with 20 mm concrete cover. The research employed the four-point load bending testing with the load span difference of each beam, which will later be the study variable. The things sought in this study include the peak load-deflection curve, the shear capacity that occurs in geopolymer concrete beams, and the shear capacity comparison with ACI 318-19. The results of the tests that have been carried out show that type A geopolymer-reinforced concrete beam was more ductile than type B beams, with a percentage difference of about 21.49% in deflection. The shear strength at the ratio a/d of 2 was 115,04 kN, and the ratio a/d of 2.5 was 89,00 kN. As well as a comparison of the shear strength of the test results with calculations according to ACI 318-19 shows a ratio of 1.69. So it can be concluded that ACI 318-19 calculations were conservative.

Abstract

This study presents the discharge calculation of open pit mining drainage system. Open pit mining is one of surface mining methods when the location of the coal is near ground surface. This research uses open pit mine at PT Maruwai Coal as the case study. Several methods of discharge calculation are performed, such as: rational method, FJ Mock and HEC-HMS model. The drainage system of the mine is analyzed using spatial analysis. The runoff coefficient based on observation and theoretical value is compared. Each calculation is compared with observation data based on pump operation on the mine. Several challenge and limitation of each method is analyzed and several parameter recommendations are given. Runoff prediction for design rainfall also compared, based on each approach. This study result can be used to optimize the run-off management on open pit mining.

Abstract

This paper explores the accuracy of nonlinear finite element procedures implemented in ATENA in predicting the load-drift response of reinforced concrete coupling beam with headed bars under reversed cyclic loading. In this study, one of the coupling beams incorporating headed bars, tested by Seo and co-workers in 2017, is analysed and its response at different lateral drifts is discussed. Parametric analyses, studying the influence of reinforcement layouts, are also presented. It is shown that the hysteresis loops of the coupling beam could be predicted accurately, along with the crack patterns at different stages of loading and failure mode. It is also shown that the omittance of headed bars resulted in more pronounced bond-slip effects and a more severe pinched response in the post-peak region, highlighting the importance of providing adequate headed reinforcement. A similar trend was observed in the coupling beam with the omittance of U-bars and horizontal transverse reinforcements, whereas stirrup relaxation was found to increase the prominence of shear failure.
