Description

The present invention is a cast asphalt mixture of new composition, in particular with new aggregate distribution, as well as an asphalt surface prepared therewith with a relatively rough, porous surface and good noise-reducing and water-draining properties.

Mastic asphalt is a mixture of minerals such as filler, usually stone dust, sand, grit or gravel and a binder, usually bitumen. Binder content and particle size distribution are metered so that the cavities are almost completely filled with binder. Mastic asphalt, for example, is used as a roadway or pavement, in underground and bridge construction as well as sealing and utility surfacing, for example in building construction or as a protective, leveling or surface layer in civil engineering.

Due to its good installation and flow properties, a road surface layer of mastic asphalt mix would have a closed, smooth surface without further processing. This would not be suitable for driving. To increase the roughness of the surface and the grip takes place in the usual mastic asphalt regularly a scattering with grit or sand, which is incorporated into the surface.

The noise development of asphalt pavements is also playing an increasingly important role. A smooth surface generates much more noise by rolling tires than a surface with cavities, eg. As the so-called open-pored asphalt. Due to the art-related smooth surface not scattered Gussasphaltdecken these produce when tire rolling relatively much noise.

The DE19538774C1 describes a mastic asphalt of coarse, structure-forming material, fillers and bitumen as a binder in which the structure-forming material is wholly or partially formed of particulate heat-resistant, low specific gravity porous materials. This asphalt contains 30-50% by weight of graded refractory porous materials, 20-30% by weight of filler, 10-15% by weight of binder and sand graded to 100% by weight.

The DE 10 2005 004 906 A1 describes a cold processable emulsion based mastic asphalt containing binder and a mineral mixture with filler. According to the examples, this asphalt contains 20-28% by mass of rock flour, 20-37% by mass of sand, 35-58% by mass of chippings, 9.5-13% by mass of bitumen-based binder emulsion and 0.5 g -4.5 wt .-% cement.

The WO2010 / 089097A1 describes a self-compacting bituminous mixture of the following composition: Slag content with an aggregate> 1 mm, between 60 and 80% by mass, sand content of natural sand or crushed sand with a particle size> 0,063 mm and <2 mm, between 2 and 15 M. %, Filler content with an aggregate <= 0.063 mm between 12 and 25% by mass, binder content between 6.0 and 8.5% by mass. Essential for this Asphaltmischgut is a very binder-rich, fine-grained mixture of binder, filler and sand.

The object of the present invention was therefore to provide a mastic asphalt which is cost-effective, in particular energy-efficient in manufacture and installation, in which post-treatment, in particular by splintering, can be dispensed with and which has a noise-reduced and water-draining surface in comparison to conventional mastic asphalt.

The cast asphalt mixture according to the invention is characterized in particular by a relatively high proportion of coarse aggregates compared to conventional mastic asphalt mixtures. It is not obvious that this high proportion - but also despite this high proportion - can be used to obtain a mastic asphalt that meets the requirements of the the task has mentioned properties. Normally, mixtures with such a high proportion of coarse aggregates are difficult or even impossible to stir in asphalt mixing machines. In order to solve this problem, the inventors have found that the disadvantage of poor stirrability can be compensated by a correspondingly adapted aggregate profile over all aggregates. At the same time, the high proportion of coarse aggregates seems to ensure that relatively many coarse rocks come to rest when installed on the surface, where they provide a rough, porous surface. This rough, porous surface allows to dispense with the subsequent spreading with grit and at the same time ensures through the porous cavities for the noise-reducing and water-draining properties.

• i) 2.4 to 5.0 wt .-%, preferably 2.8 to 4.5 wt .-% of a coarse aggregate mixture with a grain size of <11.2 mm and ≥ 5.6 mm, and 50.0 to 65.0 wt .-%, preferably 53.2 to 60.0 wt .-% of a coarse aggregate mixture with a grain size of <5.6 mm and ≥ 2.0 mm, and

• iii) 12.0 to 22.0 wt .-%, preferably 14.0 to 19.0 wt .-% of a very fine aggregate mixture with a grain size of <0.063 mm

in each case based on the total mass of all rock fractions.

Furthermore, the problem of poor stirrability can be further reduced by using, as a fine aggregate mixture, sand, preferably a natural sand / crushed sand mixture having a ratio of natural sand to crushed sand of at least 1: 1, more preferably with a ratio of natural sand to crushed sand of at least 2: 1, is used. It is particularly advantageous if the ratio of natural sand to crushed sand is at least 3: 1 or if only natural sand is used. The proportion of natural sand apparently reduces the frictional forces between the coarse aggregates, thus in particular the Spiltt, which easily interlock with each other when stirring the mastic asphalt mixture with its sharp split edges.

It is particularly preferred if the fine aggregate mixture of the cast asphalt mixture according to the invention has a flow coefficient of ≦ 40, preferably ≦ 35, particularly preferably ≦ 30. Pure crushed sand has a flow coefficient of greater than 35 or even greater than 40, while natural sand has a flow coefficient of less than 35 or less than 30. The flow coefficient is determined according to TL Gestein - STB 04, Section 2.2.7.

The cast asphalt mixture according to the invention is thus characterized by a relatively high proportion of coarse aggregates compared to conventional mastic asphalt mixtures. Any coarse-grained minerals can be used, as conventionally used for road construction, in particular for mastic asphalt, for example in the form of chippings and / or gravel. Commercially available minerals are suitable, such as basalt, diabase, greywacke, quartz porphyry or quartzite. As a coarse aggregate mixture common gravel is used in particular in road construction. In the context of the present invention, it is preferred if diabase at least predominantly (more than 50% by weight, based on the coarse aggregate mixture) or else used exclusively as a coarse aggregate mixture.

As the very fine aggregate mixture commonly used in road construction so-called filler material is used, which is a very fine-grained mineral. Normally, the filler used is rock powder, for example limestone powder. The grain size of the filler is 0.063 mm and smaller. The proportion of filler can be composed of autoloader and / or foreign filler. As autologous filler, the proportion of rock flour is referred to, which may optionally adhere to the other present in the mineral mixture minerals, in contrast to foreign fillers that are added. Examples of suitable foreign fillers are cement, hydrated lime, silica flour and others. In the context of the present invention, it is preferred if at least predominantly (more than 50% by weight, based on the coarse aggregate mixture), or also exclusively, is used as the filler, ie as a very fine aggregate mixture.

In principle, any binder or binder mixtures suitable for mastic asphalt can be used for the present invention. Examples of these are distillation bitumens of different degrees of softness, such as bitumen 20/30, 30/45 and 50/70, and modified bitumen, such as polymer-modified bitumen, for example elastomer-modified bitumen and thermoplastically modified bitumen, wax-modified bitumen, rubber bitumens or dyeable binders. Further, for the present invention as a binder in addition to the aforementioned bitumen and carbon-based binder such as pitches and paraffin-rich distillation residues of crude oil distillation and other bitumen, as they can be used for road construction, use. The binder may be used in combination with latex such as natural latex or polychloroprene latex. As binders it is also possible with advantage to use mixtures of the abovementioned binders with a reactive flux component and / or one or more fatty acids and / or an oil containing them. Suitable reactive fluxing agents include Cashew Nutshell Liquid, Cardol and Cardanol. These may be added alone or in combination with the other additives mentioned. Examples of suitable fatty acids are oleic acid, linoleic acid, linolenic acid and elaeostearic acid. These occur in nature in oils such as rapeseed, soya, Diestel, linseed or fuel oil. The proportion of reactive flux in the binders may be usually 0.5% to 25% by weight of the binder and a suitable fatty acid content of 0.5% to 10% by weight of the binder. It has been found that by adding the reactive flux component, the fatty acid and / or the oil or a combination thereof, the degree of hardness of the obtained cold Gussasphalts can be advantageously adjusted. Thus, the performance characteristics of the finished covering can be adapted to the expected stress, for example, to the respective traffic load, in a simple manner.

In the context of the present invention, the binder used is preferably a thermoplastic binder, a bitumen, a polymer-modified bitumen or mixtures of these binders or at least one binder which predominantly contains the abovementioned substances. The binder may also be a binder system which comprises, in addition to the binder, at least one viscosity-reducing additive.

A further subject matter of the present invention is an asphalt surface which comprises, at least in part, a single-layer covering layer consisting of mastic asphalt, the mastic asphalt used having the features of the mastic asphalt mixture described in detail above.

The asphalt surface according to the invention, which may be a road surface layer, an intermediate layer, a binder layer and / or a sealing layer, has a comparatively high stability, a high deformation resistance, a low noise development and a good water drainage capability.

• – optional, Glätten vorzugsweise mittels einer Walze.

An asphalt surface according to the invention can be produced by the following process comprising the steps:

• Preparing a mastic asphalt mixture as described above by mixing the respective mixture components, the mixing preferably being carried out at a temperature in the range between 160 ° C and 230 ° C,
• Incorporation of the mastic asphalt mixture, wherein the mastic asphalt mixture is preferably heated to a temperature in the range between 160 ° C and 230 ° C and / or wherein the mastic asphalt mixture is preferably incorporated by application or pouring and then stripping, and
• Optionally, smoothing preferably by means of a roller.

The cast asphalt mixture according to the invention also permits mixing at lower temperatures in the range between 160 ° C and 210 ° C. The installation can also be done at these lower temperatures.

During installation, the mix can be applied to the substrate in the usual way. For example, it can be spread with a distribution box with Abziehbohle on the ground.

It may be expedient that an aftertreatment of the asphalt mixture mixed with the substrate takes place by means of a light smooth-shelled roller, preferably a smooth-walled roller having a weight of less than 6 tons, in particular less than 4 tons. With this processing, only an alignment of the superficial grit grains takes place. This can not be compared with the expense of the previous mastic asphalt mix.

The cast asphalt mixture according to the invention is particularly suitable for the rehabilitation of cracks and open joints. The mastic asphalt mixture can in principle be used for the production of surface layers on roads and paths of all kinds, for the production of bridge coverings, for the road maintenance or repair, such as the pothole renovation or the rehabilitation of small areas. Furthermore, the casting asphalt mixture according to the invention can be used for the production of bitumen-coated screeds in residential and industrial construction as well as for the seals in facilities for handling water-polluting substances. As a rule, the installation is carried out with installation weights of 40 kg / m ² to 150 kg / m ² . The installation can be done in one, two or three layers. A dulling or roughening of the installed mastic asphalt, z. B. by scattering, is not absolutely necessary due to its rough surface, which results in a simplification compared to conventional Gussasphalten.
