Opfindelsen angår en fremgangsmåde ved udlægning af vejbelægningsmaterialer, såsom asfaltbeton, ved hvilken fremgangsmåde et eksisterende lag fejes rent og påføres et tyndt klæbelag af et asfaltbindemiddel, hvoref-5 ter et lag af asfaltmasse udlægges på klæbelaget.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a method of laying paving materials, such as asphalt concrete, wherein a method of sweeping an existing layer is applied cleanly and applied to a thin adhesive layer of an asphalt binder, after which a layer of asphalt pulp is applied to the adhesive layer.
Et vejlegeme opbygges lag for lag med forskellige materialer til vejlegemets forskellige funktioner. For at sikre at der ikke forekommer glidning mellem lagene, er det nødvendigt at forbinde lagene med et tyndt klæ-10 belag. Normalt lægges klæbelaget kun mellem de øverste asfaltlag og ikke mellem gruslagene, der i sig selv har tilstrækkelig indbyrdes friktion.A road body is built layer by layer with different materials for the different functions of the road body. To ensure that no sliding occurs between the layers, it is necessary to connect the layers with a thin adhesive layer. Usually, the adhesive layer is laid only between the top asphalt layers and not between the gravel layers, which in themselves have sufficient mutual friction.
Klæbelaget består i almindelighed af en asfalt, der er blevet opløst i et opløsningsmiddel, f.eks.The adhesive layer generally consists of an asphalt which has been dissolved in a solvent, e.g.
15 naphtha, eller af en asfalt der er emulgeret i vand. I det første tilfælde tales der om en asfaltopløsning og i det sidste tilfælde om en asfaltemulsion. Asfaltopløsningen er imidlertid nu af mindre interesse og vil formodentlig efterhånden forsvinde fuldstændigt fra marke-20 det.15 naphtha, or of an asphalt emulsified in water. In the first case there is talk of an asphalt solution and in the latter case of an asphalt emulsion. However, the asphalt solution is now of less interest and will probably eventually disappear completely from the market.
Ved den kendte fremgangsmåde til udlægning af klæbelag efterlades klæbelaget for at tørre og få vandet til at fordampe, hvorved der efterlades en klæbende as-falthinde. Denne fremgangsmåde er meget ufordelagtig, 25 som følge af venteperioden under tørringen.In the known method of laying adhesive layers, the adhesive layer is left to dry and cause the water to evaporate, leaving an adhesive asphalt membrane. This process is very disadvantageous due to the waiting period during drying.
Fremgangsmåden ifølge opfindelsen adskiller sig fra den kendte ved, at klæbelagets tørring og afbinding sker ved udlægning af den friske varme asfaltmasse på klæbelaget umiddelbart efter påføringen af dette på det 30 eksisterende lag.The method according to the invention differs from the known in that the drying and setting of the adhesive layer is effected by the application of the fresh hot asphalt pulp to the adhesive layer immediately after its application to the existing layer.
Ifølge en foretrukken udførelsesform for opfindelsen udlægges asfaltmassen hensigtsmæssigt med en temperatur på omkring 150°C.According to a preferred embodiment of the invention, the asphalt pulp is suitably laid out at a temperature of about 150 ° C.
Opfindelsen fremgår nærmere af den følgende de-35 taljerede beskrivelse.The invention will be more apparent from the following detailed description.

Asfaltmasse, der består af grus og asfalt, fremstilles på asfaltfabrikker. Herfra køres asfalten i lastbiler til belægningsstedet og anbringes i en asfaltlægningsmaskine eller påføres manuelt. Asfaltmassen har 5 da en temperatur på ca. 150°C. Efter at denne masse er blevet påført og tromlet kaldes den asfaltbeton.Asphalt pulp, consisting of gravel and asphalt, is manufactured at asphalt mills. From here, the asphalt in trucks is driven to the pavement site and placed in an asphalt paver or applied manually. The asphalt mass has a temperature of approx. 150 ° C. After this mass has been applied and drum, it is called asphalt concrete.
For at undgå glidning mellem asfaltbetonlagene anvendes som nævnt ovenfor et klæbelag, hvis sammensætning er specificeret i byggenormer.As mentioned above, in order to avoid sliding between the asphalt concrete layers, an adhesive layer is used, the composition of which is specified in building standards.
10 Ifølge den for tiden anvendte teknik, fejes det eksisterende asfaltbetonlag først rent, hvorefter klæbelaget spredes af et særskilt arbejdshold med en særlig separat enhed. Derefter ventes der i ca. et kvarter til 2 timer, indtil vandet eller opløsningsmidlet er fordam-15 pet, så der efterlades en tyk klæbrig asfalthinde. Først derefter udlægges og tromles asfaltmassen til det næste lag.10 According to the technique currently used, the existing asphalt concrete layer is first swept clean, after which the adhesive layer is spread by a separate work team with a special separate unit. Then wait for approx. a quarter to 2 hours until the water or solvent has evaporated leaving a thick sticky asphalt membrane. Only then is the asphalt mass laid out and drummed to the next layer.
Denne klæbemetode giver kun vedhæftning på "toppene", dvs. en overf1adeklæbning.This adhesive method only provides adhesion to the "peaks", ie. a surface adhesive.
20 Årsagen til at der ventes indtil vandet er for dampet er at der ifølge den hidtil fremherskende mening ikke opnås den fulde klæbeevne af klæbelaget umiddelbart efter at dette er udlagt, hvilken fulde klæbeevne er nødvendig for at forhindre det næste lag i at glide 25 under den efterfølgende tromling og under trafikbelastningen .The reason for waiting until the water is too steamy is that, in the prevailing sense, the full adhesive capacity of the adhesive layer is not achieved immediately after this is applied, which full adhesive capacity is necessary to prevent the next layer from sliding 25 below it. subsequent drumming and under traffic congestion.
Undersøgelser har nu vist, at det ikke er nødvendigt at lade klæbelaget tørre. Tværtimod opnås der i fuldstændig modsætning til den hidtidige lære et bedre 30 resultat, såfremt klæbelaget ikke får lov at tørre inden påføringen af asfaltmassen.Studies have now shown that it is not necessary to allow the adhesive layer to dry. On the contrary, contrary to the previous teaching, a better result is obtained if the adhesive layer is not allowed to dry before the application of the asphalt pulp.
Ved en typisk vejbelægning spredes asfaltbinde- midlet i mængder i størrelsesordenen fra 0,2 til 0,4 kg 2 pr. m og kan have et vandindhold på omkring 30 til 50%, 1 og asfaltmassen, der har en temperatur på ca. 150°C læg- 2 ges i mængder på ca. 60 til 120 kg pr. m .In a typical paving, the asphalt binder is dispersed in amounts of the order of 0.2 to 0.4 kg 2 per unit. m and may have a water content of about 30 to 50%, 1 and the asphalt mass having a temperature of approx. 150 ° C is added in amounts of approx. 60 to 120 kg per m.
