Definitions
- the invention relates to a method for creating a fuel-resistant Road surface based on mastic asphalt on an existing road, especially in the refueling and filling area of petrol stations as well as a fuel-resistant pavement and its use.
- the aim of the invention is therefore to provide a roadway coating, which is fuel-resistant on the one hand and an additive on the other contains, which reduces the leakage resistance sufficiently.
- the road surface should be sufficiently crack resistant that they prevent fuel from entering permanently blocked in the subsurface, and sufficiently resistant be that they face the daily wear and tear of motor vehicles resists for a long time.
- This goal is achieved with a method of the type mentioned at the beginning a fuel-resistant pavement by applying a separating layer fiber-based on an existing road surface, coating of the separating layer with mastic asphalt with a thickness of at least 2 cm, the mastic asphalt 5-20 Weight percent binder, 5-30 weight percent carbon and 50-90 Contains weight percent grit, sand and rock powder, as well as sealing Joints are created with a fuel-resistant sealant.
- the method according to the invention allows on an existing road surface a fuel-resistant and dissipative mastic asphalt layer certain Apply composition that fully meets the legal requirements enough.
- the durability and especially crack resistance is thereby achieved that the mastic asphalt layer laid floating on a separating layer will, d. H. is uncoupled from the ground.
- the carbon content ensures one adequate electrical conductivity.
- the procedure according to the invention is such that expediently previously cleaned-substrate first a separating layer on fiber basis is applied.
- the separating layer expediently consists of a Nonwoven, whereby nonwovens are applied on both mineral and carbon basis can be. Examples of this are glass fleece as well Polyester or polyolefin fleece. Naturally, other textiles Materials and fabrics are used.
- a cast asphalt layer with a thickness is made on this fiber-based separating layer of at least 2 cm, in particular at least 35 mm.
- the Mastic asphalt contains 5-20 percent by weight of common binder, 50-90 Weight percent grit, sand and rock flour as wear-reducing Hard components and 5-30 percent by weight carbon.
- Coke semolina has a relatively high mechanical resistance.
- sealant is expediently a two-component reactive curing sealing compound, especially based on polyurethane.
- sealants due to their internal networking are highly fuel-resistant, for example from Denso GmbH under the names Densolastic VT or EM sold for sealing purposes in road construction.
- the method according to the invention for creating a fuel-resistant Road surface on an existing roadway can take additional procedural steps exhibit. This may include lifting and adjusting from built-in parts that are no longer due to the application of a further ceiling have the necessary protection height, if necessary the milling an existing pavement to the maximum the thickness of the new one to be applied Layer, as well as the spreading of the finished road surface with a usual spreading material.
- the method according to the invention can be applied to different road surfaces Design can be applied. These include, for example, paving slabs, bituminous ceilings and concrete ceilings. By introducing a Separation layer is an adaptation of the asphalt layer to be applied to the type the existing pavement is not necessary.
- the optimal installation thickness is about 4 cm. To create a uniform The surface of the road surface can be locally smaller or larger without further be accepted.
- the mastic asphalt used according to the invention generally contains 5-20 percent by weight of binder, advantageously about 10 percent by weight, 5-30% by weight of coke powder, expediently more than 10 Weight percent to about 20 weight percent, 25-50 weight percent gravel, Grit and the like and 25-40 weight percent sand and rock flour.
- binder advantageously about 10 percent by weight, 5-30% by weight of coke powder, expediently more than 10 Weight percent to about 20 weight percent, 25-50 weight percent gravel, Grit and the like and 25-40 weight percent sand and rock flour.
- the invention layer used due to an increased carbon content and correspondingly reduced content of other mineral fines out.
- the method according to the invention primarily serves to seal existing non-leakproof concrete, paving or pavements Rolled asphalt. However, it can also be used to refurbish liquid-tight structures that have already been installed Road surfaces that have become in need of repair are used become. It goes without saying that the method according to the invention can also be used at any time can be used to build new roadways.
- the invention also relates to a fuel-resistant pavement layered structure, in which on an existing pavement Mastic asphalt layer lies between the existing pavement and the mastic asphalt layer is laid with a fiber-based separating layer and the mastic asphalt Contains 5-30 weight percent carbon.
- the carbon content is preferably more than 10 to 20 percent by weight and consists of coke semolina.
- the Separating layer on fiber basis consist of mineral or plastic materials, for example made of glass fiber fleece, polyester or polyulephin fleece.
- the pavement according to the invention can the usual joints and Have edge joints with a fuel-resistant sealant, as above described is filled.
- the invention relates to the use of those described above carbonaceous mastic asphalt mass together with a fiber separation layer for the creation of fuel-resistant and dissipative road surfaces in the Gas station area.
- the figure shows the structure of a road surface according to the invention an existing bituminous ceiling for carriageways.
- On the underground 7 is the old road surface with a frost protection layer 3, a bituminous Base layer 2, a binder layer 1 and the old cover layer 8.
- the old one Cover layer 8 is removed in the present case with a milling cutter and by a Glass fiber fleece 9 with a new mastic asphalt layer 5 applied thereon Carbon content replaced.
- the grout is decoupled from the substrate, i. H. it is integrated on both sides.
- the joint is only up to 3-5 mm filled in below the top edge.
- the joint flanks are in the area of the Sealant performed essentially parallel.
- a joint is made Introduced underfill, such as sand or the like. The Use of a common primer is usually necessary.
- a road surface according to the invention is placed on a composite pavement in the area applied to a gas station as follows:
- the mineral portion of the mastic asphalt layer consists of 15% by weight of 8/11 fine grit, 12% by weight of fine grit 5/8, 18 weight percent fine grit 2/5, 9 weight percent natural sand 0/2, 27.5 Weight percent limestone flour ⁇ 0.09 and 18.5 weight percent coke powder 0/1.
- the mineral components are mixed with B25 from GuS Gußasphaltwerke GmbH & co. KG in Stuttgart up to one Total binder content of 9.0 percent by weight of the mixture set.
- construction joints are cut and this like the joints to the built-in parts with the joint sealing compound Densolastic VT shed.
- the joints are usually 15/40 mm and are up to a height of about 4 mm below the road surface backfilled.
- the scattered pavement is then compacted.
