摘要

Eglin Field is located about 50 miles east of Pensacola, Florida, on the Gulf of Mexico, and the military reservation consists of a main airfield and nine auxiliary airfields, all of which have paved landing facilities. Subgrade conditions at each of these landing fields are very nearly identical -- the material being a free-draining medium to fine sand with little or no silt or clay and belonging to the SP soil classification. Low ground-water conditions prevail at the main airfield and at eight of the nine auxiliaries. In 1943 an accelerated traffic test was performed at Auxiliary Field No. 2, using wheel loads up to 50,000 lb. Settlement caused by compaction of the sand subgrade beneath the test track amounted to several inches. Thus the probability of such settlements at Eglin Field was definitely indicated for the heavier plane loads, although there was little evidence that the plane traffic to date has caused more than very minor unevenness in the pavement surfaces.
