Abstract

Increased traffic volume growth has an impact on demand for the construction of pavement structures and the use of materials used. Therefore, we need a material that can help coat aggregate materials other than asphalt in order to reduce these effects, for example polymer or plastic materials. One effort that can be done is to modify the effect of adding Low Density Poly Ethylene (LDPE) plastic as an additive in AC-BC (Asphalt Concrete-Binder Course) asphalt mixture. The purpose of this study was to determine how the effect of the addition of Low Density Poly Ethylene (LDPE) type plastics as an added ingredient of AC-BC hot asphalt mixture on Marshall characteristics. Tests conducted include aggregate testing, asphalt testing, plastic testing, and Marshall testing. The design of the mixture is done by dry (dry process) using a variation of plastic content of 0%, 2%, 3%, and 4% with each bitumen content of 4.5%, 5%, 5.5%, 6.0 % and 6.5%, the number of test specimens made is 75 test specimens. From the Marshall test results obtained KAO value of 6.5% with a variation in LDPE plastic content of 3%. With a stability value of 1878.40 kg, a flow value of 3.81 mm, an MQ value of 472.5 kg / mm, a VFB / VFA value of 72.55%, a VIM value of 4.29%, and a VMA value of 17.74%.

Abstract

To find a solution the road problem in Indonesia, it requires to perform a modified mixture to obtain good quality of asphalt concrete pavement with addition the new material. The new material as an additive to increase the quality of pavement is a Polyethylene Terepthalete (PET). This Research uses some variation as: 4%, 4,5%, and 5% of PET from weight of asphalt concrete. The purpose of this research is to identify the impact of PET as an additive in asphalt concrete wearing course (AC-WC). The metodh used in this study is a dry process from some references (such as: design and implementation of asphalt pavement used plastic waste, 2019). The result of marshall test found that the optimum performance and stability for 5% PET with 6.5% variances value of asphalt bitumen. Stability of five variation averange is 2193.3 kg; Flow is 3.90 mm; Void in Mix (VIM) is 3.7%; void mix in aggregate (VMA) is 16,7%; Void filled Bitumen (VFA/VFB) is 77.9%, and Marshall Quotient is 562,4 kg/mm. By the references used in this research, these value have been suitable with the research result from those references. It can be concluded that the asphalt pavement with using an additive of PET gives better performances and stability than without PET.

Abstract

Mortar is commonly used in construction as a strong and durable building mixture that is relatively easy to make. One of the problems that often occurs in Indonesia, especially in buildings located in coastal areas, is the rapid rusting of reinforcement or the degradation of bricks due to not receiving sufficient protection from mortar as the outermost part. Mortar plays a crucial role in construction by acting as an adhesive for bricks, wall plaster, and ceramic tiles, while also providing protection for construction joints. Because of this, the mortar needs to have the maximum strength possible. Adding alternative ingredients, such as silica fume and Superplasticizerconsol SS 74 N, to the mortar is one way to achieve this goal. Different amounts of 0.5% Superplasticizer and 10% and 20% silica fume percentage were added, and compressive strength tests were conducted after 7, 14, and 28 days. The results of the research show that the effect of adding Silica fume and Superplasticizer to mortar has the potential to reduce the compressive strength value, with the maximum compressive strength value for normal mortar aged 28 days being 49.41 Mpa, while for mortar variations of SF 10% and 20% 37.48 Mpa and 30.43 Mpa.
