NEWS-HERALD, Panama City, Fla., Friday, September .30,1977 Page 9B Quick Repair Of Bomb Damaged Runways Aim Of Tyndall Engineers SPECIAL TRUCK— Technical Sergeant Ronald A. Simmons checks the special truck being used to test the bomb damage repair project's pavement patch compounds. Fitted with aircraft tires, when fully loaded with 27,000 pounds of lead weights, this truck will simulate the weight of a jet fighter aircraft and be able to test a compounds ability to withstand repeated aircraft operations. SMOOTHING IT OVER— SSgt Tony J Holt puts the finishing touches on fresh concrete poured for a bomb damage repair program by the Air Force Civil Engineering Center's Directorate of Field Technology at Tyndall AFB AFCEC and the Civil and Environmental Engineering Development Organization (CEEDO), as part of the Air Force's efforts to increase readiness, are working together to develop the best means of getting an airfield back in operation after an attack. THE CLEARANCE CENTER AT 612 HARRISON AVENUE Now has G showroom full of values to meet your home furnishing needs. We have outstanding values for every room in your home. Come in today and let us show you how we can make your dcfllars go further. It will be our pleasure to serve you. THE BUDGET MASTER Launching aircraft from a bomb damaged airfield requires quick repair of damaged runway surfaces. The Air Force Civil Engineering Center (AFCPX) and the Civil and Environmental Engineering Development Office (CEEDO), at Tyndall AFB, as part of the Air Force's efforts to increase readiness, are working together to develop the best means to get an airfield back in operation after an attack. AFCEC has built a concrete test pad for CEEDO that simulates a typical runway. The test pad will be used to evaluate various rapid repair techniques and materials that Air Force Civil Engineers could use to get a combat damaged airfield back In operation. "We're looking for a quick, temporary repair." said Captain Raymond S. Rollings, who is handling the tests. "What we need is something that will set and cure quickly, yet provide enough strength to last until a more permanent repair can be made The purpose of all this is to allow our aircraft to retaliate immediately after an attack." In addition to determining the repair characteristics of various materials, data will be gathered on the best methods of applying the materials. "CEEDO will be conducting the testing and analysis, while the center will provide the manpower. equipment, and laboratory assistance." explained Rollings. In order to duplicate soil conditions expected in Europe and around the world, large amounts of special clay were placed over the deep Florida sand at the Tyndall test site. Above this clay, personnel from AFCEC's Directorate of Field Technology, supervised by SMSgt Roy Buschmeyer, laid 12 inches of aggregate and 10 in­ dies of concrete, "The clay we chose tor the project simulates the soil properties we expect to encounter in an area such as Europe," said Rollings. "By carefully controlling the strength ol the clay used in the tests, we can compare how the various products and construction methods compare to one another ' The program will test everything from asphalt liased compounds to exotic chemical cements, "Some ol the more exotic products are almost cost prohibitive." Rollings explained "Buying and storing large amounts of expensive and temperamental compounds only to have them go bad is one of the considerations we have to look at If one product costs ten tinic more than another, then ue have to determine if the benefits it offers outweigh the costs." To test compounds after they have been applied, a special truck fitted with aircraft tires and loaded with lead weights to simulate the weight of a ]ot tighter aircraft, is driven across the patched area. This tests the compounds ability to withslaiul the force of repeated aircraft operations. After testing, laboratory analysis of pavement patch samples furnishes data that is used to estimate the various physical properties of the products, "Because of availability and price, we are using commercial products for all of our tests." said Rollings, "If we can find off-the-shelf compounds tliat meet the desired requirements, we will save the time and money involved in developing theiTi from scratch '
