Use a org-export-filter-section-functions filter to insert "\clearpage" at
the end on headlines with the appropriate property or tag.  A quick hack:

(defun rasmus/get-org-headline-string-element  (headline backend info)
  "Return the org element representation of an element.

Won't work on ~verb~/=code=-only headers"
  (let ((prop-point (next-property-change 0 headline)))
(if prop-point (plist-get (text-properties-at prop-point headline) :parent))))

(defun rasmus/org-latex-clearpage (headline backend info)
  "Insert a clearpage at end of heading if property clearpage is non-nil."
  (when (org-export-derived-backend-p backend 'latex)
    (let ((elm (rasmus/get-org-headline-string-element headline backend info)))
      (when (and elm (org-element-property :CLEARPAGE elm))
	(concat headline "\\clearpage\\n")))))

(add-to-list 'org-export-filter-headline-functions
             'rasmus/org-latex-clearpage)

Example file:

* test
  :PROPERTIES:
  :clearpage: t
  :END:
** sub1
** sub2
