Abstract

The complication in fatique mechanism of bridges is becoming transparent through simplified basic knowledge principals. Bridges are subjected to self weight and vehicle traffic loads, causing structural deformation throughout the life time. Deformation causes stress in the bridge material. Material stress capacity is the source for bridge strength. The bridge strength that is optimal during servicability life, decreases in time of maintenance, and becomes fatique in time of replacement. Fatique mechanism is high lighted in bridge failure cases. Fatique of material needs a long process before developing into total damage, therefore a bridge structure will not collapse due to fatique conditions only. During traffic jams, resonance will occur between the heavy vehicles as vibration machine (frequency 2-3 Hertz) and steel truss girder (frequency 2-3 Hertz). Resonance between two identical frequency vibrations increases the bridge response to infinite displacement, causing a sudden failure like in an earthquake disaster. Key words : fatique, resonance, frequency, displacement

Abstract

Indonesia only produces asphalt around 650,000 tonnes annually, whilst the need for the constructions and road maintenance is about 1, 2 m illion tones. To meet those needs, Indonesia has imported asphalt from several countries. On the other hand, Indonesia has large deposit of natural asphalt known as Asbuton approximately about 200- 600 million tones which has not been utilized efficiently. Asbuton contain around of 20 % bitu men and 80% mineral. Considering that Indonesia has large deposit of Asbuton and to meet the need of asphalt shortage, new Asbuton product called “ Asbuton Murni – Pure Asbuton “ has been developed. It is extraction of Lawele Asbuton and processed to be “pure – bitumen” containing of less than 1% mineral. “Asbuton Murni” is liquid substance like pen bitumen and it can be delivered in drums or bulk, so that is a high affectivity is asphalt hot mix and easily used as other asphalt products. “ Asbuton Murni“ product has a good properties as proved from test results such as penetration, softening point, solubility, ductility, loss on heating, high penetratio n index ( + 0. 144) compared with conventional asphalt cement (- 1,127) and perfectly suited for heavy traffic with high temperature like Indonesia. The result of bituminous mixes (hot mix) using “A sbuton Murni” showed superiority compared with hot mix using conventional asphalt cement pen grade 60. Another advantage of using Asbuton Murni in hot mix is high stiffness modulus for any temperature test, therefore, it has better spread loading ability from traffic to subgrade and better resistance to permanent deformation as seen in high dynamic stability or less deformation due torepeated loads. Layer thickness for overlay in asphalt hot mix for various design traffic loading is less compared with conventional asphalt pen grade 60, resulting in significant saving. The application in Asphalt Mixing Plant (AMP) is simple because of unrequired additional special equipment, is similar to other mixing process with conventional asphalt pen grade. In short, from the above test results of both bitumen (asphalt) and asphalt mixes, “Asbuton Murni” can be able to meet the need of aspha lt shortage nationwide with a better quality

Abstract

Urban traffic congestion is a part of the day-work rutinity, and it tends to spread at wide area, then it becomes strategic issue to concern all society. TDM derives from Transportation System management focused on management demand. One of the approach which TDM used is to manage behaviour road users of urban transportation in using transportation facilities to increase the capacity and operationalisation. The scenario it to observer the behaviour of road user as a public participant. The primary data was collected through structuring interview and supported by related institutions as secondary data. The statistical non-parametric were used on data analysis using three approaches I.e, level of public preferency, participation, and public opinion priority. There is positive indication on society preferency level and there will be policy priority applied in reducing traffic congestions. In general (87%), road user agreed and would participate in running TDM policy. The highest value utility relatively is provided policy alternative on traffic jam billboard information and alternative route (36%), toll/restribution (34%), bus school private or government (32%), and expensive tariff parking-lot (32%). To apply all of them, there should be detailed study, for example, tariff study rising ability to pay (ATP) and willingness to pay (wtp), So, participation of road user in reducing of traffic congestions can be applied optimally

Abstract

Compliance testing sometimes involves measured values, which lie close to the zone of uncertainty. A different method of uncertainty evaluation by foreign authority could mean rejection of a container of goods destined for import because of expansion of the recalculated zone of uncertainty. In the era of global marketplace it is imperative that the method for evaluating and expressing uncertainty be uniform throughout the world so that measurements performed in different countries can be easily compared. This study gives the recommended method for evaluating me asurement uncertainty that is applicable for calibration and testing laboratories which based on SNI-19-17025-2000. The method of evaluating measurement uncertainty described in this studies in accordance with ISO “Guide to the Expression of Uncertainty in Measurement”.

Abstract

Recent years, there have been two issues of asphalt pavement in Indonesia i.e firstly, the supply of asphalt cannot meet national demand, so that it needs to be imported. Secondly, life design cannot be reached due to early demage resulted from inappropriate mixture used to accommodate traffic loads. To reduce imported asphalt and improve asphalt mixture performance is the use of asbuton known as Butas, mined in Buton where 677 million tonnes of natural asphalt deposit can be found which equivalent to 170 million tonnes of asphalt cement. Lawele has the most asbuton constituting 30% or 210 million tonnes but has not been utilized, on the other hand Kabungka with deposit of 60 million tonnes has been first developed. Asbuton Lawele contains 30% of bitumen, by considering the ratio of bitumen filler, the use of asphalt cement in mixture can be saved to one third resulting in saving of imported asphalt from 600.000 tonnes to 400.000 tonnes or saving of $ 100 million per year. Research result showed that hot mix asphalt added by asbuton has several advantages mainly in the increase of dynamic stability from 1457 passes/mm to 2743 passes/mm with 5% asbuton, 3283 passes/mm of 10% asbuton and resilient modulus from 2302 MPa without asbuton to 3480 MPa with 5% of as buton and 5163 MPa with 10% of asbuton. Moreone, from simulation calculation based on existing road condition and given resilient modulus of asphalt mix, as the thickness is less with the same design life and cumulative traffic load, the construction of asphalt layers with asbuton is 20% cheaper compared to asphalt layers without asbuton, although the price unit in ton is 3,7% higher for 5% of asbuton and 7,3% for 10% of asbut on, the price of asbuton is Rp. 750.000 perton. In order to have equivalent price between hot asphalt mix with asbuton and without asbuton, the price of asbuton should be Rp. 540.000 per ton in project location.

Abstract

The management of laboratory testing is highly important in achievement of certain level of qualitu standard that will be effected to the accuracy of testing result or their technical competence. Main focus of this study to evaluate the influence of application ISO/IEC 17025 to technical competence of "Laboratorium Pengujian BBPJ (LP-BBPJ)" throught out interlaboratory testing schemes that involve randomly selected sub-samples from a source of material being distributed simultaneously to participating testing laboratories for asphalt testing. After completion of testing from each laboratory, result of testing were collected and analyzed by robust z-scope to give indication of performance of their technical competence. Due to the main focus is LP-BBPJ, then only related data were analyzed by statictic descriptive to fit the generalization of the technical competence result. In general, it was found that te LP-BBPJ has been applied ISO/IEC 17025:2005 consistency. The effect of this application, either it can be provide a good accuracy testing and it can be used as a reference of asphalt laboratory testing due to the result of analyses for asphalt testing are satisfied in general.
