Description

Opfindelsen angår en fremgangsmåde til fremstilling af et tyndt slidlag på asfalt, og denne fremgangsmåde er ifølge opfindelsen ejendommelig ved, at asfalten bibringes en grov og ru overfladestruktur, f.eks. ved fræs-ning eller behandling med pigtromle, og at man derpå udstøber en tynd belægning af en beton, som indeholder fibre eller på anden måde er armeret, og at betonen både stampes og vibreres. Herved opnås en lys vejbelægning af god kvalitet under anvendelse af indenlandske materialer.The invention relates to a method for producing a thin wear layer on asphalt, and this method is characterized in that the asphalt is imparted to a coarse and rough surface structure, e.g. by milling or treating with barrel drum, and then casting a thin coating of a concrete containing fibers or otherwise reinforced, and the concrete being both stamped and vibrated. This results in a light, good quality paving using domestic materials.

Fremgangsmåden ifølge opfindelsen kan specielt udføres på følgende måder, der vecl forsøg har vist sig at give gode resultater: - Der gives betonenen forkomprimering i den benyttede udlægningsmaskine, hvorpå man færdigkomprimerer ved passage af en særlig vibrationsbjælke, som er udrustet til såvel retningsbestemt stampning som højfrekvent vibration.In particular, the method of the invention can be carried out in the following ways, which have been shown to give good results: vibration.

- I det benyttede betonmateriale ligger stenmaterialets største kornstørrelse hensigtsmæssigt mellem l/3 og 1/4 af betonlagets tykkelse, og alle kom i stenmaterialet har i det mindste en størrelse på det halve af den maksimale korn-størrelse.- In the concrete material used, the largest grain size of the stone material is suitably between 1/3 and 1/4 of the thickness of the concrete layer, and all grains in the stone material have at least half the size of the maximum grain size.

- Samtidig bør sandfraktionens maksimale kornstørrelse være mindre end 1/4 af den maksimale komstørrelse for stenmaterialet.- At the same time, the maximum grain size of the sand fraction should be less than 1/4 of the maximum grain size for the rock material.

Opfindelsen skal forklares nærmere gennem nedenstående eksempel.The invention will be explained in more detail by the following example.

Eksempel.Example.

Man ønsker at udbedre slidlaget på en landevej, hvor trafikken har medført stenafrivninger, krakeleringer og stedvis revner langs kanten.You want to improve the wear layer on a country road where traffic has resulted in tear-offs, crackles and occasional cracks along the edge.

landevejen er opbygget som følger: 4 cm asfaltbetonslidlag 7 cm grusasfaltbeton af en første type 11 cm grusasfaltbeton af en anden type 15 cm mekanisk stabilt grus og 40 cm bundsikringsgrus.the road is constructed as follows: 4 cm asphalt concrete wear layer 7 cm gravel asphalt concrete of a first type 11 cm gravel asphalt concrete of a second type 15 cm mechanical stable gravel and 40 cm bottom fuse gravel.

Ved udbedringen går man frem som følger: 2 146782At the repair, proceed as follows: 2 146782

Asfaltslidlaget affræses i fornøden tykkelse til opnåelse af et retlinet og veldefineret underlag med grov og ru struktur.The asphalt wear layer is milled to the required thickness to obtain a straight and well-defined substrate with coarse and rough structure.

Den affræsede overflade renses grundigt, eventuelt ved en hø3tryksspuling.The milled surface is thoroughly cleaned, possibly by a high pressure rinse.

Betonslidlaget udlægges i 4 cm tykkelse med en as-faltudlægningsmaskine, idet materialets konsistens er tør og grusagtig.The concrete wear layer is laid out in 4 cm thickness with an asphalt paving machine, the texture of the material being dry and gravelly.

Det benyttede stenmateriale er et granitmateriale med en kornstørrelse på 8-XL mm.The stone material used is a granite material with a grain size of 8-XL mm.

Det benyttede sandmateriale har en største kornstørrelse på 2 mm.The sand material used has a largest grain size of 2 mm.

Armeringsmaterialet i betonen er polypropylenfibre.The reinforcing material in the concrete is polypropylene fibers.

Man giver materialet en forkomprimering i udlægnings-maskinen, og man foretager færdigkomprimering ved passage af en vibrationsbjælke, som er indrettet til både retningsbestemt stampning og højfrekvent vibration.The material is pre-compacted in the laying machine, and final compression is performed by passing a vibration beam adapted for both directional stomping and high-frequency vibration.

Efter færdigkomprimering forseglen materialet, eller det beskyttes på anden måde mod udtørring.After final compression, the material is sealed or otherwise protected from drying.

Vejen åbnes for trafik, når slidlagets bøjningstrækstyrke er nået.The road is opened to traffic when the bending tensile strength of the wear layer is reached.
