Abstract

Abstract In an effort to increase the strength of pavement structures in addition to the use of hot asphalt mixture with new specifications, the selection of material types used is very important. In addition to asphalt, coarse aggregates and fine aggregates, the filler is one component in the mixture that has a large role to Marshall properties which is also a mixed performance against the traffic load. The implementation of this pilot work aims to compare mixed / stirring results using only stone ash and mixture/stirring using a beach-type additive in the AC-WC composition. Implementation of this pilot work using the Marshall method, where the Marshall test is obtained results in the form of components Marshall, namely stability, flow, Void In Total Mix (VITM), Void Filled with Asphalt (VFA) and then can be calculated Marshall Its quotiety. The last test is a Marshall immersion test or Immersion test. The result of comparison between the use of fine aggregate using only rock ash and the addition of coastal sand to the properties of Marshall AC-WC (Asphalt Concrete-Wearing Course) is based on marshall characteristic values indicating that the use of sand in asphalt concrete mixture produces a stable AC- WC layer against Change in shape (smooth and solid), but has no durability to the effects of traffic load reps and is bleeding, and is not flexible enough to break easily and break.

Abstract

Abstract The snail shell in the Bai Island Region of Bengkulu City is very large, if we don't use it offensively it will disturb the surrounding environment because it is left scattered on the riverbank. As for the efforts to utilize this waste, one of which is the most likely one we can use is the use of this snail shell for replacing fillers in the Asphalt Concrete Binder Course (AC-BC) mixture. The purpose of this research is to determine the characteristics of a mixture of AC-BC layers with fillers from snail shell ash waste in the Bai Island area of ??Bengkulu City, while the parameters used are as follows: Stability, Flow, Marshall Quotient, cavities in the mixture (VIM), intermediate cavity (VMA), asphalt filled cavity (VFA) and evaluate the performance of the mixture against the specifications required for AC-BC coated concrete mixtures. The results obtained stability value of 0% snail shell ash is 1036.3 kg. The stability value using snail fly ash 50% 964.8 kg. The stability value of snail shell ash is 100% 880.9 kg. While the flow in the mixture of 0% snail fly ash is 3.4 mm. The flow value of 50% snail shell ash is 3.7 mm and 100% flow of snail shell ash is 3.3 mm. From this research, obtained by using snail shell ash shows that the value of stability has decreased with the increasing number of snail shell ash but still fulfills the requirements of the 2010 General Highways specifications with a requirement value of> 800 kg. The flow value also shows that the mixture meets the requirements of the 2010 Bina Marga General specifications with a requirement value of> 3 mm, although the flow value has decreased, but in 50% of snail shell ash the flow value has increased by 3.7 mm.

Abstract

Each level of the earth’s surface has a different height. Therefore, measurement of the situation and topography is important for the planning work and physical work. The important of measuring the topography and the situation as a contributing factor to the efficiency and effectiveness of a job. The high point of diffence that wiil beobtained, determinetd by the axes in the plane shown in a vertical sign measuring. Current topography measurement issues are often the topics to be consideren for the job of a plan. Elevation is one of the problems in drawing a plan of work stages. Diffrence in elevation affect the volume of a very physical job. The purpose of this study was to analyze the results of measurements of topography which will look different in height, so the difference in elevation between the measuring instrument gauges Gps ( Global Posisioning System ) and Theodolite can be optimized, making it useful for planning and as a refrence to a physical. This study uses a Gps ( Global Posisioning System ) measuring devices and measuring instruments Theodolite by performing measurements of 10 ( ten ) each STA whit its distance 50 ( fifty ) until 100 ( one hundred ) meter. STA making does not use permanent markers, but by using red paint for the singn of the measurements made with Gps ( Global Posisioning System ) measuring device are not lost. This facilitates the measurement by using a tool measure Theodolite because the measuring instrument has a point to point STA sentring these points. The data taken in each STA is the data spacing (d) optimal, elevation, coordinates and coordinates. After the data is obtained, then compared with the analytical calculation of the prevaling topography. Results of research conducted comparison elevation using Gps measuring devices and measuring instrumens Theodolite we can conclude that for accurate elevations obtained from the Gps measuring devices can not be used from the planning work and physical work for every point elevation STA produced (-) mines 1 meter (do not heve this level of accuracy of the data), it does not correspond to the actual situation on the ground. As with the Theodolite measuring devices (T.0) which as a good level of concordace data and also have a good correction. But for the distance and direction that share a common coordinate measuring device Theodolite (T.0)
