THE TRAFFICABILITY OF SOILS USED BY RUBBER-TYRED VEHICLES

BEFAHRBARKEIT VON ERDSTOFFEN BEIM EINSATZ VON REIFENFAHRZEUGEN

IN THE CONSTRUCTION AND MILITARY SPHERES AS WELL AS IN AGRICULTURE THE USE OF UNSTABILIZED EARTH ROADS IS A NORMAL PART OF THE TRANSPORT PROCESS. FOR THIS REASON CONSIDERATION IS BEING GIVEN TO THE TRAFFICABILITY OF NATURALLY OCCURRING SOILS. TRAFFICABILITY SIGNIFIES THE POSSIBILITY OF A VEHICLE MAKING PROGRESS RELATIVE TO THE GIVEN CONDITIONS OF THE TRACK AND VEHICLE. IN EVERY PHASE OF MOVEMENT (ACCELERATION, STEADY MOVEMENT FORWARD) THERE MUST BE EQUILIBRIUM BETWEEN DRIVING AND RESISTANCE FORCES. THE AUTHORS GIVE A RELATION OF THE DRIVING FORCE AT THE DRIVING WHEEL RELATIVE TO EFFECTIVE PERFORMANCE AND SPEED OF THE DRIVING WHEEL. FOR THE DRIVING FORCE THERE IS A RELATION WITH THE ROTATING SHEAR STRENGTH OF A VANE PROBE. OPPOSED TO THE DRIVING FORCE AT THE DRIVING WHEEL THERE IS RESISTANCE TO MOVEMENT WITH THE RESISTANCE TO ROLLING OF THE PLASTIC DEFORMED SOIL TRACK AS THE DECISIVE CONTRIBUTION. TO MAKE SOIL SUITABLE AS A TRACK IT HAS BEEN ESTABLISHED THAT 10 PASSES OF A LADEN VEHICLE ARE SUFFICIENT TO ACHIEVE A QUASI-STABLE CONDITION. THE DEPTH OF THE TRACK IS, IN REFERENCE TO THE GROUND CLEARANCE OF THE VEHICLE, A CRITERION FOR PRACTICAL USE. THE RESULTS OF THE INVESTIGATION LED TO THE ESTABLISHMENT OF "RECOMMENDATIONS FOR THE ESTIMATION OF THE TRAFFICABILITY OF SOILS APPLICABLE TO THEIR USE BY RUBBER-TYRED VEHICLES" FOR THE MOTORWAY CONSTRUCTION AUTHORITY OF THE GERMAN DEMOCRATIC REPUBLIC.
