OBSERVATIONS ON TAXIWAY ELMENDORF AFB, ALASKA. 1962-1964.

THE RESULTS ARE PRESENTED OF OBSERVATIONS MADE DURING 1962-64 ON A TAXIWAY EXTENSION CONSTRUCTED IN 1956 AT ELMENDORF AFB, ALASKA, OVER A SUBGRADE WITH VERTICALLY ORIENTED, ALTERNATING SILTY CLAY AND SAND STRATA. FAILURE OF THE PAVEMENT OCCURRED IN THE WINTER OF 1956-57 DUE TO EXTENSIVE CRACKING CAUSED BY FROST HEAVE. THE PROBABLE CAUSES OF THE FROST HEAVE ARE STATED AND COMMENTS ON THE PAVEMENT FAILURE ARE PRESENTED. OBSERVATIONS ON A GROUND TEMPERATURE ASSEMBLY INSTALLED UNDER THE PAVEMENT AND VERTICAL MOVEMENT POINTS ESTABLISHED ON THE SURFACE ARE ANALYZED. IT IS CONCLUDED THAT THE USE OF SUBSURFACE DRAINAGE LINES HAD ONLY A LIMITED EFFECT ON FROST HEAVE AND THAT DESIGN FOR SIMILAR UNUSUAL SOIL CONDITIONS SHOULD PROVIDE FOR FULL FROST PROTECTION OR EMPLOY OTHER EXPEDIENTS SUCH AS INSULATION. /RRL/A/
