Abstract

The road is expected to meet the criteria of "Fast, Nyama, Safe, Beautiful and Sustainable" ascriteria for reviewing the performance of roads. Evaluation or study was conducted to review oneaspect of road based on speed or travel time required by the traffic on the roads, and theevaluation is done by correlating the data IRMS (Integrated Roads Management System) and BMS(Bridges Management System) to services section one way to road performance component of"travel time" traffic required for condition of roads and bridges on the road conditions, theprimary and secondary data conducted in 2010 on the national road network in the province ofJambi using data IRMS in 2010 and BMS in 2009. This study aims to review the performance ofthe street on the national road network in the province of Jambi. Thus it can be taken a linkagethat the travel time required by the traffic to move from one place to another are affected by thecondition of roads and bridges on the road, up to now the results of the IRMS and BMS as aninstrument (Benchmark / Standard) used by policy makers as a basis for determining future goodprogram planning, maintenance, and development. While the actual conditions on the ground arenot in accordance with the results of the IRMS and BMS were taken by decision of the currentconditions specified policy.

Abstract

The level of slope safety is influenced by several factors. Such as slope conditions with largeloads, steep slopes and heavy rain conditions. This often results in landslides around the TransSumatra toll road, Pematang Panggang. So that around the slopes reinforcement is needed so thatthe slopes are more stable.Based on the results of laboratory tests and research in the field, the results of the calculation ofthe slope safety value program with a 30% saturation degree condition, the safe factor value is1.2946, the degree of saturation 40%, the safe factor value is 1.2881 and the degree of saturationis 60%, the safety factor value is equal to 1,2761. Because the lowest safe factor value is at 60%saturation degree, slope stability is handled at 60% saturation degree, which is strengthened bythe cutting method on the slope body and using sheet pile to get slope reinforcement. Two methodsof handling slope stability were carried out. From the comparison of slope stability handling with60% degree of saturation, the safe slope conditions are in handling one because there is nosubsidence and soil displacement to the free slope area.

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

Liwa Cross Roads – Intersection of Kemala Mount KM.268 + 550 is located on the hills of TNBBS Lampung which geographic conditions consists of cliffs and ravines are quite steep, so prone to sliding. This is certainly very harmful to the building and the road users around the slopes so that necessary alternative solutions that could make the slopes safe from the danger of landslides. One way is to build reinforcement construction on a slope such as geotextiles and cantilever retaining wall. In analyzing of the slope stability used a computer program, that is SLOPE/W, is used to calculate the safety factor accurately in a short time. Existing slope stability analys with the program SLOPE/W Bishop methods in wet and dry conditions obtained value of safety factor 0.433 and 0.4. These results prove the structure of the slopes is not safe, it is needed solutions to handle slope sliding that has a stable numerical secure slope value by using woven geotextile reinforcement by the number of 16 layers, tensile capacity 200 kN/m, cohesion 3 kPa and the friction angle of the soil 38o, vertical distance 2 m and a cantilever concrete retaining wall that has a height 15 m with a specific gravity 25 kN/m3, the compressive strength of concrete plans (f'c) 30 MPa and a tensile strength steel (fy) 400 MPa. Pile soil used to improve slope geometry made to reduce the slope. The results of slope sliding stability analysis, reinforced with geotextile using SLOPE/W obtained value of safety factor 1,332, while reinforced with cantilevered retaining wall at 1.852. For the analysis of external stability by geotextiles strengthening obtained bolsters safety factor 5.9479, shear stability 3.3531 and carrying capacity 3.4815, while the cantilevered retaining wall reinforcement obtained stability bolsters safety factor 6.0643, shear stability 2.2346 and carrying capacity 3.1828. Key words: Slope stability, stability of retaining walls, Geotextile, SLOPE/W.

Abstract

The Indonesian Transportation System, which is still dominated by ground transportation, has made the road have a more dominant role in economic growth. The condition of road facilities and infrastructure also encourages economic growth among regions connected by infrastructure networks, so that it is expected that in various regions there will be equitable growth.The collapse of the Lempuyang bridge resulted in a change in the volume of traffic flow on the roads that became an alternative road. This volume change can directly affect the condition of the road designated as an alternative road, namely the eastern crossroad (Sukadana - Sp. Bujung Tenuk) and the Tegineneng Feeder - Sukadana road.The segment most affected by the damage to the Lempuyang bridge is the Central - Metro - Sukadana feeder segment. In the Central - Metro - Sukadana feeder there was an increase in the size of the slightly damaged  road  in May 2015 from  2014, from 2.52% to 9.03%. The value of severely damaged conditions in the Central - Metro - Sukadana feeder also increased where in 2014 it was worth 0.00% to 5.34% in May 2015. Keywords: East Cross Road, Lempuyang Bridge, Road Condition Value

Abstract

There are three intersections that are within 1.3 km of study focused on Jalan Z.A. Pagar Alam.  The problem that sometimes occurs is vehicles must stop at every intersection because it always gets a red signalThe data collection was done by a direct survey at all three intersections. The data that taken from the intersection are geometric and volume intersection.  The first intersection released from signal coordination between intersections, with a cycle time of 63 seconds was obtained degree of saturation on average 0.7378 and the queue length 70.23 m. After three planning between the intersection II and III intersection obtained the best cycle time of 99 seconds. The average degree of saturation of intersection II is 0.77 with queue length 146.71 m and the third intersection is 0.85 with queue length 82.03 m. Because the degree of saturation is approaching 0.8 and 0.8 exceed existing special construction needs to be done.
