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 .

Traffic accidents are serious problem in Bandar Lampung City, especially the Soekarno-Hatta Bandar Lampung By Pass Road, considering that this road is the primary arterial road that should not be disturbed by shuttle traffic, local traffic, and local activities. Roadside activities are one of the disruptions that can cause accidents and need to be analyzed. Blackspot are determined by the Equivalent Accident Number (EAN) method based on accident fatality rate each segment of the road. Roadside activities are grouped into pedestrians and crossers (PED), park and stop vehicles on the side of the road (PSV), slow moving vehicles (SMV), also enter and exit vehicles of activity centers (EEV). Analysis with linear regression is used to calculate the level of impact of roadside activities with accident rates. From 25 segments along Soekarno-Hatta Road, 16 segments are classified as blackspot and 6 segments are still classified as blackspot until 2017. EEV is the highest number that affects the decrease in the number of accidents, PSV for the 2nd number, SV for the 3rd number and PED for the smallest number. Besides the average vehicle speed is only 42,8 km/h due to the high volume of vehicles with an average of 2708 skr/h also the damaged of some segments and poor support facilities of the road.

Handling road damage using the greenroads method is one solution to the problem of natural resources. This method uses a recycling method of dismantling the old pavement layers to be used as a mixture of new pavement layers. This study aims to determine the use of Reclaimed Asphalt Pavement (RAP) material as a mixture of materials to be used again as AC - WC (Asphalt Concrete - Wearing Coarse) pavement and determine the best percentage between recycled asphalt mixture from RAP and new material. The results of this study were obtained for the stability value on the use of 25% RAP, 50% RAP and 75% in a row obtained 1300,320 kg, 1076,468 kg and 966 kg. Of the three variations in the use of RAP it has mixed characteristics and marshall characteristics that meet the General Specifications of Bina Marga. The Optimum Asphalt Content (KAO) value for the percentage of RAP use of 25%, 50% and 75% in a row obtained 5,8%, 5,6% and 5,4%. The higher the use of RAP percentage, the Optimum Asphalt Level (KAO) obtained is getting smaller.

One causes of construction failure on flexible pavement is changed composition of the aggregate gradation in asphalt mixture of the plan due to mechanical or non-mechanical process. Aggregates can occur degradation, ie gradation changes due to aggregate breakage of grains. Aggregate degradation can be caused by both mechanical and chemical processes. The decrease in quality occurring in the asphalt mixture is thought to be due to the aggregate gradation change in the asphalt mixture. To find this out, a study on the degradation level of flexible pavement construction is conducted,from Asphalt Mixing Plant to overlay location. Used mixture are Asphalt Concrete-Wearing Course produced by PT. Manggung Polah Raya for location on Sultan Agung Street, Bandar Lampung, Lampung and PT. Rindang Tigasatu Pratama for location on Teuku Cik Ditiro Street, Bandar Lampung, Lampung. Test of samples performed are extraction test and sieves analysis test. From the research result, it is founded that there is degradation during transport of asphalt mixture from Asphalt Mixing Plant to the location. Average degradation percent of location I, location II and location III PT. Manggung Polah Raya and PT. Rindang Tigasatu Pratama is %CA decreased by 5.17%, %FA increased by 3.67% and %filler increased 1.50%. Factors affecting degradation are due to work execution, specific gravity of aggregate and time of transport.Keywords: Road Pavement, Asphalt Concrete, Degradation
