Qe CWLR - 2370 ~ LABORATORIES AND FIELD STUDIES CANDIDATE RADIOLOGICAL ul WARFARE ADHESIVE AGENTS (U). M. A. Schmoke and R. J. Smith, May 1960. CONFIDENTIAL The objectives of this investigation were to conduct laboratory and field studies on the effects of varying climatic conditions on the adherence of certain candidate radiological warfare (RW) liquid adhesives “4 to road surfaces under conditions of realistic military traffic on these adhesives. The adhesives tested were polymethyl methacrylate (Lucite) in ethylene dichloride, polystyrene in ethylene dichloride, and yellow traffic paint, Fed Spec TY-P-li5a. Tracer quantities of zirconium-niobium oxide were mixed with all the adhesives to simulate the RW contamination and for radiological evaluation purposes. Laboratory tests were made in the Atlas Weather-Ometer to determine the effects of moderate and high temperatures and humidities on the durability of the adhesives. Four field tests were conducted to } determine the adhesives' durability under various traffic and climatic conditions: (1) ! winter, passenger vehicles; (2) summer and fall, passenger vehicles; (3) winter, tanks and heavy trucks; (4) fall, military armored convoy. . . j The conclusions to be drawn from this report are: | 1. Varying weather conditions have no appreciable effect on the bonding properties of the polystyrene adhesive formulation. 2. The polystyrene adhesive formulation demonstrates excellent adhesive and wear resistance on asphaltic roadways under heavy and light military traffic up to the test traffic density of 3,000 vehicles a month. 3. The polymethyl methacrylate edhesive formulation shows very : 4. Traffic paint shows excellent possibilities as a bonding 4 poor adhesive properties and wear resistance. agent because it held up slightly better than polystyrene and was less : troublesome to prepare.
