#CMT# #/CMT# The system (1) has an excavation area provided under a ground (34) and provided with a gas line (3), a drinking water line (4) and a drainage line (5). A laminar soil exchange area (6) is extended over a width of the ground in the excavation area. An embedment and the soil exchange area are filled with a self-condensing and hardable material mixture (10) i.e. soil binder, which is brought in a flowable form. The embedment is provided in the soil exchange area and/or in utility trenches (7, 8), whose width is smaller than that of the ground and is lower than the soil exchange area. #CMT# : #/CMT# An independent claim is also included for a method for constructing a roadway. #CMT#USE : #/CMT# Roadway constructing system. #CMT#ADVANTAGE : #/CMT# The embedment and the soil exchange area are filled with the self-condensing and hardable material mixture that is brought in the flowable form with less time expenditure. The mixture is self-condensed and hardable, so that the separate condensing step is eliminated. The excavation area is provided with the gas, drinking water, and drainage lines, thus improving bearing capacity of the roadway in a reliable manner. The design of the system reduces cost expenditure for establishing the roadway construction. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional view of a roadway constructing system. 1 : Roadway constructing system 3 : Gas line 4 : Drinking water line 5 : Drainage line 6 : Laminar soil exchange area 7, 8 : Utility trenches 10 : Material mixture 34 : Ground. |
