Abstract
Abstrak
Penggunaan perkerasan kaku merupakan pilihan yang cukup baik, untuk jalan tol yang dilewati oleh beban cukup berat dan kecepatan cukup tinggi. Sifatnya yang lebih kuat dan lebih tahan lama, dibandingkan dengan perkerasan lentur menyebabkan perkerasan kaku menjadi pilihan yang tepat. Akan tetapi telah diakui bahwa sumber kelemahan struktur perkerasan beton semen konvensional terletak pada sambungan Melintang (transverse joint) dan perkuatannya.. Bentuk kerusakan antara lain terjadinya retak, faulting, pumping dan spalling pada sambungan sehingga mempengaruhi kenyamanan berkendara.
Salah satu pendekatan untuk mengurangi masalah pada sambungan antara lain adalah penggunaan perkeraan beton tanpa sambungan melintang yaitu dengan perkerasan beton bertulang menerus (Continuously Reinforced Concrete Pavement, CRCP). Namun Continuous Reinforced Concrete Pavement (CRCP) juga memiliki kelemahan yaitu, rancangan yang mengakibatkan defleksi berlebihan akibat beban lalu lintas berat.
Hal ini dapat diatasi dengan pendekatan menggunakan beton prategang (Prestressed Concrete Pavement, PCP). Namun sistem Precast Prestress Concrete Pavement (PPCP) ini terdapat kelemahan pada sambungannya, yaitu dapat terjadi crack yang disebabkan tidak adanya tulangan pada daerah sambungan antar panel nya. Namun hal ini dapat diatasi bila digabungkan dengan perkerasan jenis Continuous Reinforced Concrete Pavement (CRCP).
Tugas Akhir ini membahas tentang Perencanaan Ulang Perkerasan Jalan Kaku (Rigid Pevement) Jenis Continuous Reinforced Concrete Pavement (CRCP) Dengan Metode Precast Prestress Di Jalan Tol Solo – Ngawi. Dari hasil perhitungan yang dilakukan didapat tebal pekerasan beton konvensional dengan tebal 305 mm dengan umur rencana (UR) 40 tahun sedangkan tebal perkerasan jenis Continuous Reinforced Concrete Pavement (CRCP) sama didapatkan tebal 200 mm atau lebih tipis karena adanya baja prategang yang membuat beton lebih mampu menahan tarik akibat beban. Baja prategang (strand) yang digunakan diameter 12,7 mm dengan jumlah pada setiap tendon/duct 2(dua) unit strand. Panel direncanakan dengan ukuran 1,8 m x 12 m dan 3,6 m x 12 m.
Dalam hal metode pelaksanaan, pelaksanaan perkerasan kaku konvensional cenderung lebih lama dibandingkan dengan Perkerasan Jalan Kaku (Rigid Pevement) Jenis Continuous Reinforced Concrete Pavement (CRCP) karena perkerasan kaku konvensional menunggu waktu 28 hari untuk digunakan sedangkan Perkerasan Jalan Kaku (Rigid Pevement) Jenis Continuous Reinforced Concrete Pavement (CRCP) dapat digunakan 3 hari setelah proses grouting dan stressing.
Rencana anggaran biaya yang dibutuhkan untuk pelaksanaan perkerasan konvensional adalah sebesar Rp. 1.550.548.215.920 sedangkan untuk perkerasan dengan metode prestress precast adalah sebesar Rp. 2.966.102.136.014 untuk panel ukuran 1,8 m x 12 m dan sebesar Rp. 2.634.027.811.365 untuk panel ukuran 3,6 m x 12 m.
=========================================================
The use of rigid roughness is a pretty good choice, for a toll road that passed by quite a heavy load and the speed is high enough. Its nature is stronger and more durable than the pliable stiff roughness cause roughness becomes the right choice. But it has been recognized that the source of the weakness of the roughness of conventional concrete structure located on the connection Bar (the transverse joint) and perkuatannya ... Among other forms of damage occurrence of faulting, cracking, spalling and pumping on the connection so that it affects the ride comfort.
One approach to reduce the problem of the connection between the other is the use of perkeraan concrete without transverse connection i.e. with reinforced concrete roughness continuously (Continuously Reinforced Concrete Pavement CRCP,). But Continuous Reinforced Concrete Pavement (CRCP) also have weakness, namely, the draft which resulted in excessive deflection due to heavy traffic loads.
This can be overcome by using concrete approach prategang (most reputable Prestressed Concrete Pavement, PCP). But the system of Precast Prestress Concrete Pavement (PPCP) there are weaknesses on the connection, that can happen to a crack caused by the absence of reinforcement on the connection between his panel. However this can be overcome when combined with Continuous Reinforced Concrete type roughness Pavement (CRCP).
This thesis discusses the Planning of road Roughness Anniversary Stiff (Rigid Pevement) type of Continuous Reinforced Concrete Pavement (CRCP) and the method of Precast Prestress In Solo Highway – the paths. The results of calculations performed in conventional concrete pekerasan thickness obtainable with 305 mm thickness with age plan (UR) 40 years while the thick Reinforced Concrete Continuous type roughness Pavement (CRCP) just 200 mm thick is obtained or thinner because of the steel prategang that makes concrete more able to withstand the drag due to the load. Steel prategang (strand) 12.7 mm diameter are used with a number on each tendon/duct 2 (two) unit of the strand. The planned panel size 1.8 m x 12 m and 3.6 m x 12 m.
In terms of method execution, implementation of a conventional rigid roughness tend to be longer than with a Rigid Road Roughness (Rigid Pevement) type of Continuous Reinforced Concrete Pavement (CRCP) due to the roughness of the conventional rigid waiting time 28 days for use of road Roughness while Stiff (Rigid Pevement) type of Continuous Reinforced Concrete Pavement (CRCP) can be used 3 days after the grouting process and stressing.
Budget plan costs required for the implementation of conventional roughness is Rp. 1.550.548.215.920 while for the roughness of precast prestress method is Rp. 2.966.102.136.014 to the panel size 1.8 m x 12 m and Rp. 2.634.027.811.365 for panel size 3.6 m x 12 m
