Abstract

The flexural strength of rigid pavement is the dominant parameter that influences the concrete pavement performance. In general, concrete is weak against its flexural tensile strength. One alternative that can be used to increase its flexural tensile strength is by adding artificial fibers and/or natural fibers to the concrete mixture. The purpose of this research is to find the effect of adding gelam bark fibers towards compressive strength, split tensile strength, and flexural strength of concrete using PCC cement. In this study, the concrete mixture was added with various percentages of fiber content i.e. 0,2%; 0,3%; 0,4%; 0,6%. The concrete was tested and compared its value of compressive strength, split tensile strength and flexural strength. The results of this study showed that the most influential use of fiber for concrete pavement was 0,4%. The addition of gelam bark fiber by 0,4% could increase the tensile strength of the concrete mixture aged 28 days and 56 days respectively by 6,95% and 23.72% toward the concrete without fibers. The testing of concrete at 28 days age results the split tensile strength value decreased by 4,2% and the compressive strength test decreased by 4,7%.Keywords: Gelam bark fiber, PCC cement, OPC cement, flexural tensile strength, split tensile strength and compressive strength

Abstract

Material requirements for road pavement have increased along with major developments in Lampung Province. This causes the availability of aggregates to become thinner. One alternative replacement material is RAP (Reclaimed Asphalt Pavement). The aggregate in RAP becomes a potential that can be used as a basic material for road foundation layer. Therefore, research on the potential of RAP (Reclaimed Asphalt Pavement) if used as a base course material.This study uses RAP material obtained from the asphalt pavement layers on Soekarno-Hatta Street, Bandar Lampung.  The results of the maximum dry density value obtained from three behaviors amount of blow is 1.965 grams / cm3, so that the resulting CBR value is 51%. This is caused during mixing and blows, the added water cannot enter perfectly into the RAP cavity. Because RAP granules are coated with asphalt so it is impermeable. So it can be concluded that the potential RAP used in this study cannot be used in road foundation layer class A but can be used as a road fondation layer class S. And if an additional of blows are made in each layer, RAP potentially can be used as a class B road foundation material. Keywords : RAP (Reclaimed Asphalt Pavement), Base Course, Optimum Moisture Content.

Abstract

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.
