Abstract

Currently, the use of steel as a building construction has been widely used as the main material for building structures. Steel frames come in a variety of profiles and sizes. The use of steel frames can be adjusted to the type of construction to be built. From the results of the planning of the WF steel roof structure on the factory warehouse construction project in Pamekasan, it was obtained planning data: Gording using Profile C 125x50x40x4,5. Trekstang uses 8 mm diameter, Wind ties use 10mm diameter steel, Rafter uses WF 350x350x19x19 profile, column uses WF 350x350x19x19 profile, 8 pieces A325 bolts with 22 mm diameter, Hoist Crane Beam uses IWF Bulit-Up beam with 600x1144x18x22 profile, Base Plate uses a size of 500x500x8mm with a column of 600x600.

Abstract

Granite waste is generated at the time of processing the granite rock that is not utilized, it can be also a rest – the rest of the project. Utilization of waste material roughness to granite road is one way to reduce the waste of the granite. This research aims to know the benefits of waste granite coarse aggregate as substitute against marshall on the mix characteristic laston or AC-b. ingredients used include: Semen Gresik brand Filler, sand purchased from stores building in Kediri, Grey stone which in may from Winongsari Grogol, corals that are purchased from shops in Kediri, Asphalt comes from Pertamina, granite Waste obtained from the project. Mix laston or AC-L with granite rock waste as a substitute for coarse aggregate using a variation of 10%, 20%, and 30%. The results of this research it is known that the use of granite waste can enhance the characteristics of Marshall. Mix the waste with best laston granite aggregate as substitute coarse waste levels obtained at 20%, with the following results: Marshall Stability 1050.67 kg, Melting/4.00 mm Flow, Marshall Quotient 262.67 mm.

Abstract

The road is one of the most important infrastructures. The community needs it because the road functions to connect the source of production. Asphalt is an aggregate binding material in road pavement construction, which plays an important role in determining road pavement performance. Road Pavement, in general, uses materials that are still fairly common. This study uses a fine aggregate of crushed concrete specimens. The method used is an experiment on the addition of concrete test specimens with percentages of 10%, 20%, 30%, 40%, and 50%. Marshall method which is the basis for calculating the stability value and flow. the results of 5 Marshall test samples of asphalt concrete mix utilizing concrete waste obtained the characteristics of the average value of the study that all had met Highways' requirements at a VMA value of 18.22%, a value of 4.22 VIM.%, VFB value 75.04%, STABILITY value 4806 kg, FLOW value 3.24 mm, and Marshall Quotient (MQ) value 14958.1 kg / mm.
