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.

Abstract

The demand for an acceleration of project completion time is often an obstacle, especially in structural work which is a critical path. The length of time for concrete curing and formwork dismantling sometimes obstructs the progress of the project. The time required for casting, concrete curing and unloading of formwork in a long span bridge construction project is ± 14 days with a record that there are no obstacles in the field. Based on these problems, researchers are trying to provide an alternative solution through a compressive strength test with a variant of the concrete quality and the curing time using chemical additives type F and type D. The study aims to find the minimum concrete compressive strength, the curing time, and the effects of adding a chemical additive that refers to General Specifications Standard 2018 (70% of the designed concrete compressive strength). The variant of the concrete quality is 40 MPa, 50 Mpa, and 60 Mpa while the variant of the curing time is 1,2,3,7, and 28 days. Based on the study, the minimum concrete compressive strength for each concrete quality is 28,58 MPa, 36,85 MPa, and 46,25 MPa. The curing time needed for fc’ 40 MPa and fc’ 50 Mpa is 2 days while for fc’ 60 MPa is 3 days. The use of chemical additives also has an impact on increasing compressive strength. The maximum compressive strength value of 28 days is found in the variation of f'c 60 Mpa of 62.20 Mpa with additive content of type F dan D of 0.6% and 0,15% of the cement weight. Optimum compressive strength is achieved when the curing process is done using the soaking method. Key words: critical path, formwork, chemical additives, compressive strength, soaking method.

Abstract

The road improvement of Sp.3 Janas (National Road) to STI along 2.5 km (Sta. 0+000 – Sta. 2+450) is carried out to support the development of the Belanti Food Estate area. The road has been built with a width of 3.5 m with single layer asphalt pavement and will be increased to 6.0 m wide and 3.8 m wide road shoulders (right-left). In the existing plan, the soil layer under the widening of the road will be installed with galam woodpiles as subgrade reinforcement. The need for large quantities of galam wood as subgrade reinforcement for road improvement is feared to have a negative impact on the environment, especially illegal logging. Therefore, minipile concrete pillars are an alternative for subgrade reinforcement used to prevent environmental damage due to the use of large amounts of galam wood. An analysis of the stability of the embankment and subgrade settlement was carried out by using the two subgrade reinforcements which were then compared in terms of strength to withstand loads and their cost requirements. The improvement of the Sp.3 Janas road (National Road) to STI along 2.5 km (Sta. 0+000 – Sta. 2+450) will cost Rp. 1,078,000,000,- for the use of galam wood and Rp. 31,752,000,000,- for the use of minipile concrete pillars. The total subsidence of 11.0 m of soil (depth -1.0 to -12.0 m) was 17.3 cm with a difference of 6.6 cm on the side of the road widening using galam woodpiles. If using minipile concrete piles, the total subsidence of the soil layer will be 13.3 cm with the difference in settlement on the widening side of the road using minipile concrete poles of 7.0 cm. Keywords: soft soil, galam wood, woodpile, minipile, road widening

Abstract

Integrity testing on deep foundations,better known as its trademark PIT, is one of the tests that aims to determine the integrity of the foundation. Integrity can be in the form of the length of the pile and the enlargement and/or downsizing of the pile foundation. There is no standard that regulates the minimum age of concrete when the integrity test is carried out, but it is often carried out after the age of 28 days of concrete with a wave propagation value of Ws=3,800 m/s and there is no correction value if the test is carried out at a concrete age fewer than 28 days. The research was conducted to test the integrity using PIT on the bored pile in the Bromo area, where the age of the concrete when tested was 1 and 11 days. Based on the results of the study, it was found that there was a difference in the displacement of the concrete enlargement of 11.5% on the tested bored pile. However, with reference to that the PIT integrity test is a quality test, not quantity test, so that the effect of concrete age on integrity testing, especially using PIT, can be ignored. Key words: integrity test, deep foundation, bored pile, concrate age, deep foundation, wave speed.

Abstract

In the soil failure model, the strength of soil masses is controlled by the friction of grains, as analogous to the strength of intact rock in the rock mass failure. Discontinuity strength is obviously not considered in the soil failure criterion. Slopes of weathered rock masses analyzed in this paper were located on the two cut slopes of highway construction on the southern coast of East Java, Serang Beach – Malang Regency Section. The rock mechanic approach was applied by using a non-linear failure criterion of generalized Hoek-Brown. This criterion was correlated to the linear failure criterion of Mohr-Coulomb which was common in a slope stability analysis practice. Analysis using generalized Hoek-Brown was always generating critical factor of safety (FS), compared to the Mohr-Coulomb equivalent with FS difference of 50.5% and 16.03% at the STA. 16+350 and STA. +14+125 respectively. Critical slip surfaces produced by generalized Hoek-Brown were always laying on the shallower area, compared to the Mohr-Coulomb critical slip surfaces. Keywords: weathered rock slope, generalized hoek-brown, equivalent mohr-coulomb, geological strength index, southern coast java road.

Abstract

The application of LRB technology on bridges in Indonesia is not as popular as in developed countries, even though Indonesia is one of the countries with the highest frequency of earthquake occurrences. LRB technology is more popular in its application to building structures. However, LRB technology has been widely applied to road and bridge infrastructure, especially on toll roads. Even Indonesia has been able to produce LRB with better quality and quantity compared to other countries. This study aims to determine the performance improvement of bridges using LRB in accommodating earthquake forces. This study examines the results of bridge monitoring by replacing the placement system in the form of bearing pads with LRB. Installation of LRB is carried out on a steel frame bridge with a length of 65 meters. This load test is carried out with 4 (four) methods of loading a 6 (six)-wheel truck load. Installation of 4 accelerometer sensors (two vertical bridge directions and two bridge transverse directions) installed in the middle of the span. In addition to the installation of the accelerometer, LVDT was installed in the longitudinal direction of the bridge. Based on the results of the analysis, it is found that the natural frequency value of the upper structure the bridge does not change (that is, 4.64 Hz). There was an increase in the performance of the bridge bearing system, especially the damping time from 7.36 seconds to 4.01 seconds with the same magnitude value. Keywords: steel truss bridge, LRB, cencor, frequency, damping.

Abstract

Rock fall is a very fast bedrock movement where material is released from a steep slope and moves by falling, bouncing, rolling or sliding. West Java Province has a frequency of 1129 landslides throughout 2020 which underlies the need for a study of locations that have the potential for rock fall and simulation calculations to determine the type of rock fall barrier that can be used at that location. Rock fence as a passive slope protection method as one of the rock fall countermeasures. The analysis is carried out using software to determine the most appropriate type of rock fence method. Based on the analysis, the maximum kinetic energy at Location 1, Location 2 and Location 3 was 1,630.68 kJ, 1,209.11 kJ and 397.82 kJ, respectively. Thus, the countermeasure for Location 1 can use a Category 4 rock fence with the maximum energy level value being in the range of 1500 kJ MEL < 2000 kJ, while countermeasures for Locations 2 and 3 can use Category 3 and Category 1 rock fences respectively. Further collection of slope geometry data and historical rock fall data is needed to be able to simulate various rock fall conditions, rock reflection heights and rock maximum kinetic energy so as to sharpen the analysis results. Keywords: rock fence, rock fall classification, kinetic energy, slope protection, simulation
