Abstract

Roads are transportation infrsstructure that connects one area with other areas, especially in the transportation sector for the smooth flow of goods and services. Roads experience damage due to the incereasing volume and load of vehicles, especially if they are always passed by heavy vehicles that are overloaded. The Namlea - Marloso road section has a length of 19,026 km with a road width of 4.0 m. This road section has road damage to the road surface layer in the form of cracks, holes, and surface defects. Previously damaged road conditions have been repaired by patching using CPHMA. However, the planned life of the road is in fact not in accordance with what is happening in the field. The road has been damaged ± 4 months after being repaired. The aim of the research was to determine the marshall characteristics of CPHMA-type Buton asphalt mixture using rock ash as filler and to analyze the percentage of rock ash content that met the requirements for Buton CPHMA-type asphalt mixture. This study used rock ash with the addition of 4%, 8% and 12%. This test was carried out using a Marshall test kit with reference to the 2020 Bina Marga Specifications and the Indonesian National Standard (SNI). The research results show that the average values obtained are density value =2.21 gr/cc, marshall stability value =1416 kg, flow velue =3.02 mm,, VMA value =18.24%, VIM value =7.72%, VFB value =63.18%, MQ value =483.02 kg/mm. marshall CPHMA characteristics with the addition of rock ash resulted in increased stability, flow, VMA and VIM values. While the values of VFB and MQ decreased. Presentation of optimum rock ash addition content =6% and meets the 2018 Bina Marga specification revision 2.

Abstract

This research was conducted to test the comparison of compressive strength of concrete using Tonasa cement and Conch cement. Remembering that cement is the most important material in making concrete. So many people use Portland cement in making concrete. The aim of this research is to determine the compressive strength of concrete that is good for use in construction work. In this research, Tonasa cement and Conch cement were used to determine the compressive strength of concrete at the age of 3 days and 7 days in the Ambon State Polytechnic laboratory, civil engineering department. With 12 cylindrical test objects with a diameter of 15 cm and a height of 30 cm. The method used in this research is an experimental method, to investigate the relationship between the compressive strength of compression testing machine concrete and the hammer test number test. the result showed that the  average compressive strength is : Tonasa cement was 41.52 Mpa for cylindrical concrete, 500.23  for cube concrete at 3 days old and 28.16 MPa for cylindrical concrete, 339.32  for cube concrete at 7 days and Conch cement of 38.92 Mpa for cylindrical concrete, 468.97  for cube concrete at 3 years of age. days, and 26.86 MPa for cylindrical concrete, 323.58  for cube concrete at the age of 7 days.

Abstract

This condition causes the asphalt mixture to be unable to be overlaid on the road work site because the temperature of the mixture is below the overlay and compaction temperature. According to the provisions of the asphalt mixture that has experienced a decrease in temperature can no loger be used. But the reality that happens a lot in the field is that sanding is still done and followed by the next stage, namely compaction. Therefore, it is necessary to conduct research on the effect of heating on the concrete asphalt layer mixture, namely hot rolled sheet-Base (HRS-Base). The method used, the effect of AC-WC asphalt mixture temperature on the specific gravity of road work is . From yhe results of the marshall analysis, the value of marshall parameters that meet the requirements is in the range of asphalt content 4.50-5.80 so that the optimum asphalt content is obtained at the middle value of the limit range above is 5.12%. Comparison of asphalt temperature to field temperature and lab asphalt temperature. The asphalt temperature in the lab is 5.5% asphalt content and the asphalt temperature used in the lab is 160°C, 150°C, 140°C, 130°C, while the asphalt content used in the field is 5.0% asphalt content and the asphalt temperature used in the field is 125°C, 135°C, 140°C, 145°C. Further research needs to be carried out in the form of marshall soaking tests with the intention of measuring the durability of the binding/adhesion of asphalt mixtures to the influence of temperature.
