Repair
Within the airstrip locality, there are no borrow pits nearby only sites where the locals ‘harvest’ stones and sand for building purposes. Water is readily available,a grader and roller are the only machines that will be required to rehabilitate the airstrip.
With no borrow pits near-by, the best approach to rehabilitating the airstrip would be to strip the runway surface of grass and silt, scarify 100–150 mm, shape and compact the surface. A side drain should be excavated for on the LHS with scour checks provided at 50m intervals while mitre drains should be provided on the RHS at 100m intervals. The water mains cutting across the runway should be protected; by providing a plastic (PVC) sleeve and haunching (surround) the sleeve with concrete. The PVC pipe size should be reasonable enough so as to act as a service duct for further use in future.
Edge markers should also be provided on both edges of the runway. Well arranged stones should be placed at 10 m intervals and painted red every 50 m. The access roads should also be diverted to a single service road on either side of the runway / airstrip area to avoid vehicular traffic going across the airstrip. At some point, an office building will be required at the very least to house communication equipment and maintain records.

Famous quotes containing the word repair:
“The land is the appointed remedy for whatever is false and fantastic in our culture. The continent we inhabit is to be physic and food for our mind, as well as our body. The land, with its tranquilizing, sanative influences, is to repair the errors of a scholastic and traditional education, and bring us to just relations with men and things.”
—Ralph Waldo Emerson (1803–1882)
“It is not only a question of who is responsible for very young children. There is no longer anyone home to care for adolescents and the elderly. There is no one around to take in the car for repair or to let the plumber in. Working families are faced with daily dilemmas: Who will take care of a sick child? Who will go to the big soccer game? Who will attend the teacher conference?”
—Fran Sussner Rodgers (20th century)
“It is not difficult to deceive the first time, for the deceived possesses no antibodies; unvaccinated by suspicion, she overlooks latenesses, accepts absurd excuses, permits the flimsiest patchings to repair great rents in the quotidian.”
—John Updike (b. 1932)
