Abstract

Bertambahnya volume pengguna jalan yang kian padat setiap tahunnya, maka perlu penambahan kapasitas jalan agar mampu menampung jumlah kendaraan yang semakain padat ini. Namun dengan menambah kapasitas pada ruas jalan karena adanya penambahan volume kendaraan ini, mengakibatkan beban yang harus ditopang oleh jalan itu semakin besar. Pada penelitian yang dilakukan kali ini dengan adanya bahan adictive yakni bubuk silicasebagai material perkerasan jalan campuran beraspal, guna mengetahui kelayakan penggunaan limbah tak terpakai ini. Metode Penelitian yang digunakan adalah metode eksperimental di laboratorium. Kinerja campuran beraspal ditentukan berdasarkan daya dukung campuran berdasarkan parameter stabilitas dan volumetrik dengan metode Marshall (SNI 06- 2489-1991) dengan 30 benda uji dari penambahan bubuk silica sejumlah 3%, 5%, 7%, 10% dan 12%  dari berat benda uji dengan kadar aspal 4%, 5%, 6%, 7% dan 8%. Setelah serangkaian uji laboratorium didapatkan kandungan kadar aspal optimum pada penambahan kombinasi bubuk silica3% sebesar 6%. Dengan rincian hasil rata-rata nilai Stabilitas 1186kg, Flow 4,17mm, dan MQ 286 kg/mm.

Abstract

Foundation is a structure that functions to withstand loads above it and the load itself. These loads are transferred to the ground directly. The case study in this plan is the construction of the Dwi Indah Building in Selodono Village, Kediri Regency. The building has a building area of 308 m2 and a height of 16 m, with the function of the building as an inn. In this planning, the type of pile foundation is used. A Pile foundation is a type of deep foundation that divides the gravity load evenly on the ground and makes the structure of the building strong and strong. The purpose of this planning is to plan a strong pile foundation that is able to withstand the load of the Dwi Indah Building. The method used in this planning is the Meyerhoff method, with a pile diameter of 30 cm and a foundation depth of 800 cm. From the calculation results obtained (single pile bearing capacity) Pall= 42.62 tonnes greater than (maximum pile load) Pmax= 26.00 tonnes (SAFE). For the control of the yield of the buckling factor, the result is (buckling) ω= 178.61 kg/cm2 <(base stress) σ = 2400 kg/cm2 (SAFE).
