Abstract

Bridges are one of the most important means of transportation for humans. In the construction of bridge construction, there are 2 methods used namely conventional and pre-cast methods. Both of these methods have differences in the construction of the upper building structure alone. In the pre-cast bridge construction: When the work for the upper structure of the building is 59 days, the number of workers is 130 people, the work barriers are not too constraining the traffic. Whereas in conventional bridge construction: The work time is 110 days, the number of workers is 104, the obstacle of work will hamper the traffic below. From the analysis of the two types of bridges, pre-cast bridges are 20% more expensive than conventional bridges, but the pre-cast bridge work time is 51 days faster.Keywords : Pre-cast bridge construction, Conventional bridge construction .

Abstract

Pavement is widely used in Indonesia is a mixture of laston, in its implementation  temperature is very influential on the overlay process, temperature also affects the density process. The further the distance of AMP (Asphalt Mixing Plant) to the overlay location, the greater the decrease in temperature, and the decrease in density results. So it is necessary to do a study about effect of spread distance to mixed temperature change. The mixture used is Asphalt Concrete-Wearing Course from Asphalt Mixing Plant produced by PT Manggung Polah Raya for location on Sultan Agung Street, Bandar Lampung, Lampung and PT. Rindang Tiga Satu Pratama for the location of Teuku Cik Ditiro Street, Bandar Lampung, Lampung. From the analysis results of 2 AMP (Asphalt Mixing Plant), PT. Manggung Polah Raya and PT. Rindang Tiga Satu Pratama using logarithmic regression analysis, obtained that the distance and the Δtemperature are 0,9832 and 0,7366. The result of Δtemperature and Δdensity are 0,0568 and 0,0688 and the result of distance logarithmic regression analysis and Δdensity are 0,0326 dan 0,005. The result of the combined logarithmic regression analysis of PT. Manggung Polah Raya and PT. Rindang Tiga Satu Pratama between distance and Δtemperature is 0,7829 and 0,0005 for Δtemperature and Δdensity. Factor that influence the decrease of the temperature is the haulage process of the transport mixture. If the temperature decrease, then the result of the density are not maximal.  Keyword: Mixture Temperature Change, Distance, Density.

Abstract

Land is the basis of a pavement structure. Best part of the land to construct a road construction is land that has a high density value. To determine the density of a soil, CBR testing is needed. CBR testing itself is divided into 2, namely field CBR and laboratory CBR. Location taken was between Padang Tambak Liwa - Liwa City Limits. This research will be conducted to find out how much influence the correlation of Field CBR values and Laboratory CBR on the road. In this study researchers will conduct Water Content Test, Filter Analysis, Atterberg Limits, Plastic Limit Test, Specific Gravity, Standard Soil Compaction, laboratory CBR Test, which uses disturbed subgrade from Padang Tambak Liwa - Liwa City Limits and then obtained a graph of the CBR laboratory test data results then compared with the existing field CBR graph. In the correlation of the value of the CBR field test and the laboratory CBR test there are samples that have an average deviation value below 5%. As for STA 227 + 500, STA 230 + 500, STA 233 + 000 there were different results of deviations from 26 samples, there were 3 samples that were above 5% deviation. This can be caused by uneven soil conditions, differences in precision of laboratory equipment with the tools used in the field, different forms of penetration characters in CBR testing.

Abstract

Bridges are constructions that connect people and land transportation that is blocked by obstacles. One of which is the type of cable stayed bridge.. This bridge structure consists of a combination of various structural components such as pylon, cable and deck. The deck is hung with a prestressed cable that is anchored to the pole. Gravitational and lateral forces acting on the bridge deck will be transferred to the ground via cables and pylon. The cable will receive tensile force and the pylon accepts the compressive force. This bridge planned 800 m long, 14 m wide traffic, 1.5 m sidewalk width, elongated girder type is tub girder, 300 mm plate thickness, cable arrangement is 2 fields and fan, and the cable used is VSL 7-wire strand. Girder quality of 290 MPa, concrete quality of 35 MPa, and welding quality of 490 MPa. Bridge model calculations are supported by SAP 2000 and Microsoft Excel programs. From the calculation results obtained the reinforcement design for the sidewalk using the main reinforcement D16-150 mm and reinforcement for D13-200 mm, reinforcement for vehicle floors both in the field and pedestal with the main reinforcement D22-100 mm and reinforcement for D16-100 mm. The dimensions of the girder used were flanges of 1 m x 0.05 m, web 1.3 m x 0.01 m and lower fluxes 4.2 m x 0.04 m. To get a more stable structure design, 3-dimensional analysis is needed. Keywords: Cable Stayed Bridge, Tub Girder, Girder

Abstract

In the field of highway damage to road pavement in addition to weather factors and overloading can also occur due to poor subgrade. A good alternative so that the soil on the highway subgrade does not experience excessive swelling is to use cement additives.Soil samples were tested using subgrade soil material originating from the RA. Basyid passageway of Fajar Baru Village, Jati Agung Subdistrict, South Lampung at STA 3 + 900 and variations of cement used were 0, 4, 8 and 12%. The test carried out is by testing the swelling of soil against CBR which has been marred for 3 days, then based on the results of the test, the calculation of pavement thickness was carried out by the method of analysis of components of SKBI 2.3.26.1987.In testing physical properties, the soil includes the classification of A-6 soil or poorly categorized soil types. However, after adding variations in soil classification cement into a good A-2-4 category. In the CBR swelling test on 0% cement percentage swelling values were 0.62% and CBR 0.9%, in the 4% percentage swelling value 0.27% and CBR 42.6%, at the percentage of 8% swelling value 0.19% and CBR 53.2%, and 12% percentage swelling value 0.06% and CBR 78.1%. From the calculation of the pavement thickness, the greater the CBR value, the thicker the thickness of each layer.Keywords: CBR, Soil Swelling, Pavement Thickness, Stabilization, Cement

Abstract

 Asphalt is one of the materials used as a road-making material. Needs for ashpalt modification are caused by restrictions and capabilities of basic asphalt binder material to withstand pressure. Lignin functions as a binding for wood cells. Lignin is used as an additive to improve the quality of bitumen material. The binder used is 60/70 asphalt penetration. The lignin material used comes from palm oil fiber waste. The variation of lignin addition on asphalt levels is 0%, 3%, 6%, 9%. Characteristics test of asphalt carried out is Asphalt Specific Gravity, Penetration, Ductility, Softening Point, Oil Weight Loss, Viscosity. Asphalt in this study experienced an increase in quality. The best mixing of lignin is 3% and 6%. Shown by the Penetration test, the value of asphalt penetration increased to 53.6 mm. The sensitivity of asphalt to rising temperatures is indicated by the softening point test reaching 62˚C. 6% lignin mixing is the highest value for the effect of asphalt viscosity of 827 cst. The value of asphalt density reaches 1.0714 gr / cm3. In the 9% lignin mixture there is a decrease in the Ductility test, Viscosity test, Asphalt Specific Gravity test. Keywords: Asphalt, Lignin, Modification, Penetration, Viscosity.
