Transport Laboratory

HEAD of LABORATORY
Prof. SIGIT PRIYANTO

Transport Laboratory is located on the 2nd Floor of the east Civil Engineering Building. This Laboratory consists of Road Engineering Laboratory and Transport Laboratory. This laboratory is used for students and lecturers research for all degree in the Department of Civil and Environmental Engineering.

Transport lab is located in the 2nd floor of east wing of CEED. It consists of road engineering lab and transportation lab and used for undergraduate to post-graduate students and academic staffs. This lab is incorporated with various government and private institution for road pavement research.

Road engineering lab is provided with equipment to support various test, such as Marshall test, length gauge, surface texture depth, permeability test, frictional surface, CBR test, Los Angeles test, speedy moisture, shrinkage limit, Hubbard field test, core drill, etc.

Transportation lab is provided with various equipment, such as Automatic Counter TDC-8 with data processor, speed gun, Piezo Electric Axle Sensor, GPS 48 Personal Navigator, audio visual equipment, and communication equipment.
