Abstract

Pertumbuhan jumlah penduduk berdampak pada meningkatnya tingkat konsumsi masyarakat. Hal ini menyebabkan volume sampah yang dihasilkan juga mengalami peningkatan seiring bertambahnya populasi manusia. Paving block (beton paving) merupakan material bangunan komposit yang dibuat dari campuran semen Portland atau bahan perekat lainnya, air, dan agregat, dengan atau tanpa bahan tambahan lainnya, selama tidak mengurangi mutu beton (mengacu pada SNI-03-0691-1996). Dalam penelitian ini, limbah pasir digunakan sebagai bahan tambahan dengan variasi komposisi sebesar 10%, 20%, dan 30%. Plastik yang telah dilelehkan kemudian didiamkan hingga mengeras pada suhu ruang. Dari hasil penelitian diperoleh beberapa kesimpulan terkait berat benda uji, berat volume benda uji, serta kuat tekan. Nilai kuat tekan paving block plastik normal dan paving block plastik dengan variasi substitusi agregat pasir (PBP1, PBP2, dan PBP3) secara berturut-turut adalah 76,48 Kg/cm², 87,25 Kg/cm², 72,65 Kg/cm², dan 49,71 Kg/cm². Berdasarkan pengujian yang dilakukan, berat benda uji untuk paving block plastik normal serta variasi dengan substitusi pasir PBP1, PBP2, dan PBP3 masing-masing adalah 0,979 Kg, 1,14 Kg, 1,232 Kg, dan 1,384 Kg. Sedangkan untuk hasil pengujian densitas, nilai yang diperoleh untuk paving block plastik normal dan paving block dengan variasi substitusi pasir PBP1, PBP2, dan PBP3 berturut-turut adalah 0,815 g/cm³, 0,845 g/cm³, 1,026 g/cm³, dan 1,153 g/cm³.

Abstract

In transportation engineering, road pavement is commonly categorized as either flexible pavement or rigid pavement. The pavement demonstrates a distinct capacity to endure a variety of loads, including compressive and tensile loads. The capacity to endure compressive and tensile forces is extremely important, especially in the field of pavement construction, as it ensures both the longevity and the safety of the pavement. The objective of this study was to evaluate the capacity of hot mix asphalt to endure compressive and tensile pressures. The experimental methodology employed four different wire mesh deployment configurations on hot asphalt mixtures, utilizing three-point flexural test equipment. The data indicates the most effective method for mimicking hot mix asphalt involves adding a wire mesh layer at a depth of 30 mm below the surface of the experimental specimen. The particular modeling method showed a measurement of flexural resistance up to 291.85 kN. The study's findings indicate that the hot asphalt mixture exhibits a state of balance in its capacity to endure both compressive and tensile pressures. Incorporating a wire mesh layer within the middle section of the hot asphalt mixture has been perceived to enhance its ability to withstand tensile loads, hence improving its overall performance.
