Abstract

ABSTRACT This research is part of a long-term study in an effort to discover a kind of asphalt concrete mix that is both economical and highly durable at up to 600 celsius under flood water submersion. The research is conducted by testing the dynamic stability of hot mix asphalt concrete as to simulate vehicle wheel load on a flexible road pavement. The tested mix utilizes portland cement and stone dust as the filler aggregate, as well as soft-gradation stone ash bina marga 2010 with pertamina asphalt, asphalt concrete mix with retona asphalt, and asphalt concrete mix with superpave-gradation aggregate. All those mixes undergo the marshall stability test as well as residual stability and refusal density tests beforehand to achieve the most optimum composition. The marshall stability test is conducted with different submersion times, ranging from 24, 72 to 120 hours, at temperatures ranging from 300, 380 to 600 celsius. The dynamic stability of the mixes is tested by a wheel-tracking device at 300 and 600 celsius. The data is analyzed through the regression analysis method. After treatment, results showed that the mix of bina marga fine gradation with stone dust filler and retona asphalt 55has highest dynamic stability with lowest rate of deformation.

Abstract

Abstract Drainage is a series of waterworks that serve to reduce and remove excess water from the land or in a region, so that the land can function optimally and is defined as the infrastructure that serves the water and the surface water body or to buildings and artificial recharge. The goal is to help resolve the problem of flooding that occurred in Perum Griya Asri Wika Jatiranggon Bekasi. Data processing method using a manual calculation according a rational method for calculation the debit of rain, and Manning formula for the debit channel. After calculating, it is known there are many dimensions that couldn’t accommodating the needs of existing discharge so that the most rational solution to cope with the flood was able to do normalization and change the existing channel which was originally made of stone into a u-ditch dimensional (50.70.120cm) Keywords: Flood, Drainage, Capacity, U-ditch. Abstrak Drainase adalah serangkaian bangunan air yang berfungsi untuk mengurangi dan/atau membuang kelebihan air dari suatu kawasan atau lahan, sehingga lahan dapat difungsikan secara optimal dan diartikan sebagai prasarana yang berfungsi mengalirkan air permukaan ke badan air dan/atau ke bangunan resapan buatan. Tujuannya untuk membantu menyelesaikan permasalahan banjir yang terjadi pada Perum Griya Asri Wika Jatiranggon, Bekasi. Metode pengolahan data menggunakan perhitungan secara manual sesuai dengan metode rasional untuk menghitung debit hujan, dan rumus manning untuk debit saluran. Setelah dilakukan perhitungan maka diketahui masih banyak dimensi yang tidak mampu menampung debit kebutuhan yang ada sehingga solusi yang paling rasional untuk mengatasi banjir tersebut adalah dengan melakukan normalisasi pada saluran dan mengubah saluran eksisting yang semula terbuat dari batu kali menjadi u-ditch dimensi (50.70.120cm).

Abstract

The planning and evaluation process of toll road pavement thickness play a crucial role in sustainable toll road design. Road structure design needs to align with construction requirements, and pavement serves to shield the road layers from excessive pressure due to vehicle loads. Recalculating the rigid pavement thickness on the Cinere - Jagorawi toll road section III using the AASHTO and MDP methods aims to determine the most suitable method for determining toll road pavement thickness. Additionally, the study conducts cost calculations for rigid pavement work using slipform concrete paver and conventional methods. The research findings indicate that based on project data analysis, the pavement thickness using the AASHTO method is 16 cm, while the MDP method results in a thickness of 28 cm. The MDP analysis yields a pavement thickness identical to the field measurement of 28 cm, whereas the AASHTO method produces a pavement thickness 12 cm thinner than the field measurement. The effective cost of rigid pavement work using manual methods and concrete pavers amounts to Rp11,640,674,008.34. This cost applies to a thickness of 29 cm, a lane width of 3.7 m, and a work length of 5,700 m. The maximum work length is 3,291 m using manual methods, and the minimum work length is 2,409 m using concrete pavers.
