PROPOSED NEW DESIGN PROCEDURES USING THE CBR METHOD FOR MILITARY ROADS AND AIRFIELDS

A NEW APPROACH TO THE METHOD OF PRESENTING INFORMATION FOR DESIGNING SHORT TERM MILITARY ROADS AND AIRFIELDS BY THE CBR METHOD IS DESCRIBED: PART 1: FOR ROADS A FORECAST OF TRAFFIC INTENSITIES AND SPECTRA HAD BEEN MADE BY THE WAR OFFICE FOR FORCE, CORPS AND BRIGADE ROUTES, AND A SET OF CURVES WAS PREPARED, USING THE MEANS EMPLOYED BY THE ROAD RESEARCH LABORATORY FOR PREPARING THE CIVIL ROAD CURVES PUBLISHED IN THEIR ROAD NOTE 20. A RELATION WAS LATER DEDUCED BETWEEN ANY GIVEN TRAFFIC INTENSITY AND ITS SPECTRUM AND THIS ENABLED THE CONSTRUCTION OF A NOMOGRAM FROM WHICH THE REQUIRED PAVEMENT THICKNESS COULD BE DERIVED FOR ANY GIVEN INTENSITY OF TRAFFIC, FOR ANY PERIOD OF TIME, WITHIN THE SHORT TERM RANGE. PART 2: FOR AIRFIELDS, THE ISSUE OF LAND AIR WARFARE POLICY STATEMENT NO.5, CALLED FOR DESIGN PROCEDURES FOR CERTAIN CLASSES OF AIRCRAFT. THE MINIMUM OF PREPARATORY WORK WAS SPECIFIED AS AN ESSENTIAL FEATURE OF TEMPORARY AIRFIELDS AND, CONSEQUENTLY, THE UNSURFACED CONDITION WAS FAVOURED. THREE SETS OF CONDITIONS WERE CONSIDERED: FIRSTLY-UNSURFACED SOIL COVERED SOLELY WITH A WATERPROOFING OR DUST PROOFING MEMBRANE; SECONDLY-SOME FORM OF FLEXIBLE PAVEMENT, AND THIRDLY-PREFABRICATED LANDING MATS. IN ALL CASES THE USAGE TO BE CATERED FOR WAS SPECIFIED IN TERMS OF NUMBER OF COVERAGES OF THE SURFACE BY THE WHEELS. CURVES HAVE BEEN DEVISED TO COVER ALL THE EVENTUALITIES STIPULATED, AND ARE BASED ON THE ORIGINAL US CURVES WHICH WERE NOT THEMSELVES APPROPRIATE FOR THE SPECIFIC CONDITIONS REQUIRED.
