Farndon Archaeological Research Investigations has applied for Heritage Lottery Funding to investigate fields around Farndon, where the site was discovered during field walks carried out before the widening of the A46.
Hundreds of Ice Age flint tools have been unearthed from the fields, which is believed to have been a camp.
If successful in their funding bid archaeologists hope to use the money over three years to carry out field walks, dig several test pits and carry out scientific tests which they would not be able to afford otherwise.
Professional archaeologist Daryl Garton, who was involved in the initial work with the Highways Agency, said the future work on the site was incredibly important.
"There isn't another site in Britain of the same age and with this spread of activity," she said.
"There were about 330 surface finds but that was just the tip of the proverbial iceberg.
"There will be lots more in the ploughed soil, hopefully left intact."
