Description
Det er kjent plastlaminater, bestående av en polyesterfolie av høy fasthet og et smeltepunkt over 250°C, som på begge sider har et sjikt av polyetylen av lav densitet. (Se "Kunststoff-Rundschau", mars 1967, side 121, punkt 5.1.1.8). Plastic laminates are known, consisting of a polyester foil of high strength and a melting point above 250°C, which has a layer of low-density polyethylene on both sides. (See "Kunststoff-Rundschau", March 1967, page 121, point 5.1.1.8).
Ved fremstilling av flerelags asfaltbelegg i gate-bygning er det en kjent foreteelse at spesielt de øvre sjikt som eksempelvis består av støpeasfalt eller asfaltbetong og har en annen sammensetning og struktur enn det underliggende binde-sjikt, viser løsningstendenser. Disse løsningstendenser bevirkes ved dampspenninger som oppstår når det varme oversjikt påføres på bindesjiktet, da sistnevnte i sine hulrom har vann, hvilket spontant fordamper under de nevnte betingelser. Dekksjiktet har ved påføring en temperatur i området fra l60 til 240°C. Derved virker den dannede dampspenning mellom de to sjikt således at det øvre, nypåførte sjikt heves eller dampen bevirke'r dannelse av et flertall små kanaler i oversjiktet, hvorigjennom den deretter strømmer ut. Om den ene eller andre foreteelse opptrer, avhenger av det øvre asfaltlags sammensetning, ved hulromrikere oversjikt vil kanaldannelsen være foretrukket, ved hulromfattigere sjikt hevningen av dekksjiktet. Inntreden av vann i bindesjiktets hulrom er praktisk talt ikke å unngå da det vanligvis mellom på-føringen av dette og dekksjiktet ligger et lengre tidsrom, således at bindesjiktet under denne tid er utsatt for alle klimainn-virkninger. When producing multi-layer asphalt pavements in street buildings, it is a well-known phenomenon that especially the upper layers, which for example consist of cast asphalt or asphalt concrete and have a different composition and structure than the underlying binding layer, show a tendency to loosen. These dissolution tendencies are caused by vapor stresses that arise when the hot top layer is applied to the binding layer, as the latter has water in its cavities, which spontaneously evaporates under the aforementioned conditions. When applied, the cover layer has a temperature in the range from 160 to 240°C. Thereby, the generated steam tension between the two layers acts so that the upper, newly applied layer rises or the steam causes the formation of a plurality of small channels in the upper layer, through which it then flows out. Whether one or the other phenomenon occurs depends on the composition of the upper asphalt layer, in the case of a void-rich upper layer, channel formation will be preferred, in the case of a void-poor layer, the raising of the cover layer. The entry of water into the binding layer's cavity is practically unavoidable, as there is usually a longer period of time between the application of this and the cover layer, so that the binding layer is exposed to all climatic influences during this time.
Det er kjent å anvende plastfolier, fremfor alt i gatebygg, idet her folien for det meste anvendes som ensjikts-materiale, og ikke i asfaltdekket, men under frostbeskyttelses-sjiktet, som består av ikke bundet materiale, for å oppnå avdek-ning mot oppstigende fuktighet fra råbakken. Slike folier kan på grunn av sin anordning i bygningslegemet verken bidra til å forbedre bindingen av to lag av et flerelags asfaltbelegg eller hindre inntrengningen av vanndamp fra asfaltbindesjiktet.i. de der. ■ overliggende^* as f ålts j ikt. Det'er videre kjent å innbygge plast-vevnader i asfaltbelegg for å forbedre beleggets strekkfasthet, tilsvarende jernarmering ved stålbetong. Slike vevnader er uegnet som vanndampsperrer. It is known to use plastic foils, above all in street construction, as here the foil is mostly used as a single-layer material, and not in the asphalt pavement, but under the frost protection layer, which consists of unbound material, in order to achieve coverage against rising moisture from the raw soil. Due to their arrangement in the building body, such foils can neither contribute to improving the bonding of two layers of a multi-layer asphalt coating nor prevent the penetration of water vapor from the asphalt binding layer.i. those there. ■ overlying^* as f ålts j ikt. It is also known to incorporate plastic webs into asphalt pavements to improve the pavement's tensile strength, similar to iron reinforcement in reinforced concrete. Such fabrics are unsuitable as water vapor barriers.
Oppfinnelsen vedrører anvendelse av et laminat, bestående av en polyesterfolie av høy fasthet og et smeltepunkt over 250°C, som på begge sider har et sjikt av polyetylen av lav densitet, til fremstilling av et flerelags gate- eller veibelegg ved pålegging av laminatet på et asfaltbindesjikt og etterfølgende påføring av et asfaltdekksjikt i varm tilstand. The invention relates to the use of a laminate, consisting of a polyester film of high strength and a melting point above 250°C, which has a layer of low-density polyethylene on both sides, for the production of a multi-layer street or road surface by applying the laminate to a asphalt binding layer and subsequent application of an asphalt cover layer in a hot state.
Laminatet har fortrinnsvis en samlet tykkelse i området mellom 0,10 og 0,50 mm, fortrinnsvis i området 0,12 til 0,25 mm, og særlig foretrukket 0,18 mm. Med polyesterfolie av høy fasthet menes en slik hvis strekkfasthet er større enn 2000 kg/cm 2 , fortrinnsvis 2200 kg/cm 2. Laminatéts polyesterfolie har et smeltepunkt over 250°C, fortrinnsvis et smeltepunkt på 260°C. Polyesterfolien har en tykkelse i området fra 20 til 75/Um, spesielt en slik fra 25 til 50yum og spesielt foretrukket en på 36/Um. The laminate preferably has a total thickness in the range between 0.10 and 0.50 mm, preferably in the range 0.12 to 0.25 mm, and particularly preferably 0.18 mm. By high-strength polyester film is meant one whose tensile strength is greater than 2000 kg/cm 2 , preferably 2200 kg/cm 2 . The laminate's polyester film has a melting point above 250°C, preferably a melting point of 260°C. The polyester foil has a thickness in the range from 20 to 75 µm, especially one of this type from 25 to 50 µm and particularly preferably one of 36 µm.
Polyetylensjiktet har en flatevekt i området fra The polyethylene layer has a basis weight in the range from
46 til 180 g/m , fortrinnsvis i området fra 60 til 138 g/m og spesielt 69 g/m 2. Som polyetylen av lavere densitet gjelder et slikt polymerisat med en densitet på 0,92 g/cm3 46 to 180 g/m , preferably in the range from 60 to 138 g/m and especially 69 g/m 2 . Such a polymer with a density of 0.92 g/cm 3 applies as polyethylene of lower density
Fremstillingen av et flerelags asfaltbelegg med hjelp av ovennevnte laminat skal beskrives i det følgende, hvor det om-tales en foretrukket utførelse ifølge oppfinnelsen. The production of a multi-layer asphalt coating using the above-mentioned laminate will be described in the following, where a preferred embodiment according to the invention is mentioned.
På et asfaltbindesjikt som har en- sammensetning i-følge DIN 1996, side 25, pålegges laminatet etter en avkjølings-tid av bindesjiktet på flere dager, således at lengdekanten av naboplasserte baner overlapper og forløper parallelt til hver-_andre. En sammenbinding av banene med hverandre i overlappings-området, f.eks. ved klebing eller sveising, er ikke nødvendig. Deretter påfører man på overflaten av laminatet det ifølge DIN 19.96, side 19, sammensatte og 160 til 2H0°C varme dekksjikt og lar det avkjøles. Det fremstilte flerelags asfaltbelegg er ut-merket ved at de to lag ikke skiller seg fra hverandre, og den skadelige porøsitet av beleggets oversjikt dannes ikke. On an asphalt binding layer that has a composition in accordance with DIN 1996, page 25, the laminate is applied after a cooling time of the binding layer of several days, so that the longitudinal edge of neighboring lanes overlaps and runs parallel to each other. A connection of the lanes with each other in the overlapping area, e.g. when gluing or welding, is not necessary. Next, the surface of the laminate is coated with the cover layer, which is composed according to DIN 19.96, page 19 and heated to 160 to 2H0°C, and allowed to cool. The manufactured multi-layer asphalt coating is distinguished by the fact that the two layers do not separate from each other, and the harmful porosity of the coating's upper layer is not formed.
Ved påføring av de øvre asfaltsjikt med temperaturer fra 160 til 240°C smelter de ytre laminatsjikt av polyetylen av lav densitet og motvirker ved avkjøling herved en sjiktadskillelse, da deretter polyetylensjiktet på den ene side er fast forbundet med dertil grensende asfaltsjikt og på den annen side med poly-esterf olien. Derved bidrar polyetylensjiktet til forankring av asfaltlaget til polyesterfolien, og dette tjener som sagt som sperre overfor den vanndamp som utvikler seg ved. påføring av det' varme dekksjikt. When the upper asphalt layers are applied at temperatures from 160 to 240°C, the outer laminate layers of low-density polyethylene melt and, upon cooling, counteract a layer separation, as the polyethylene layer is then firmly connected on one side to the adjacent asphalt layer and on the other side with the polyester foil. Thereby, the polyethylene layer contributes to anchoring the asphalt layer to the polyester foil, and this serves as a barrier to the water vapor that develops in the wood. application of the hot cover layer.
Oppfinnelsen skal forklares nærmere ved hjelp av tegningen som viser en foretrukket utførelse. Figur 1 viser skjematisk og i tverrsnitt et laminat til fremstilling av et flerelags asfaltbelegg. Figur 2 viser likeledes skjematisk og i tverrsnitt et av to asfaltlag bestående belegg som er fremstilt under anvendelse av nevnte laminat som mellomsjikt mellom de to asfaltlag. The invention will be explained in more detail with the help of the drawing which shows a preferred embodiment. Figure 1 shows schematically and in cross-section a laminate for the production of a multi-layer asphalt coating. Figure 2 likewise shows schematically and in cross-section a coating consisting of two asphalt layers which has been produced using said laminate as an intermediate layer between the two asphalt layers.
På figur 1 betyr 1 polyesterfolien og 2 betyr et sjikt av polyetylen av lav densitet. In Figure 1, 1 means the polyester foil and 2 means a layer of low density polyethylene.
På figur 2 betyr 3 asfaltbindesjiktet av et vei-dekke, 4 hulrom i dette sjikt, 5 vann og 6 vanndamp i hulrommene 4, 7 laminatet som helhet, sifrene 1, 2 og 3 har samme betydning som på fig. 1 og 8 er et asfaltdekksjikt. In figure 2, 3 means the asphalt binder layer of a road surface, 4 cavities in this layer, 5 water and 6 water vapor in the cavities 4, 7 the laminate as a whole, the numbers 1, 2 and 3 have the same meaning as in fig. 1 and 8 is an asphalt cover layer.
