34、X1.1 Thermal ResistanceX1.1.1 RCPS geofoam also functions as a thermal insula-tion.The thermal insulation properties of RCPS geofoam are asspecified in Specification C 578, and may impact the end usedesign of applications subject to different exposure conditions.Consult the RCPS geofoam manufacturer
35、 for specific recom-mendations.X1.2 Solvent ExposureX1.2.1 RCPS geofoam must be protected from petroleumbased solvents and their vapors. Examples of these solventsare: gasoline, diesel fuel, concrete curing compound, coal tarpitch, and asphaltic mastic compounds.X1.3 Equipment TrafficX1.3.1 Equipmen
36、t traffic that can impose contact pressuresin excess of the allowable design stress for RCPS geofoamshould be restricted. Protective materials such as sheathing orplanks may be placed on the material to allow light rubber-tiredequipment use.X1.4 BuoyancyX1.4.1 RCPS geofoam becomes buoyant when subme
37、rgedin water and adequate ballast must be provided to resistexpected uplift forces.X1.5 DesignX1.5.1 The design and installation of RCPS geofoam is theresponsibility of the user.X1.5.2 RCPS geofoam can be supplied precut to specifieddimensions to fit specific project needs. Desired shapes andsizes c
38、an also be field cut with a hot wire, saw, or other cuttingtool.X1.6 Ultra-Violet DegradationX1.6.1 Discoloration and dusting of load bearing surfacesof RCPS geofoam caused by extended exposure to sunlightshall be removed by pressure washing.ASTM International takes no position respecting the validi
