Definitions
- the present invention relates to a process for tack coating between layers of road surfacing material such as asphalt concrete where an existing layer is swept clean and sprayed with a thin film of asphalt tack coat, whereafter asphalt is layed out on top of the tack coat.
- a road surface is built up layer after layer with different materials for the various functions of the road.
- it is necessary to bind the layers with a thin tack coat. Normally the tack coat is only laid between the uppermost asphalt layers and not between the gravel layers which have by themselves sufficient friction between them.
- the tack coat normally consists of an asphalt which has been dissolved in a solvent, e.g. naphta, or of an asphalt which has been emulsified in water.
- a solvent e.g. naphta
- asphalt solution in the former case one speaks of an asphalt solution, and in the latter case of an asphalt emulsion.
- the asphalt solution is however of less interest now and will presumably disappear completely from the market because of the fact that it contains solvents which can be used for other purposes, i.e. as motor fuels, and the fact that they create a hazardous working environment.
- the purpose of the present invention is to achieve a process for tack coating between layers of surfacing material, which does not have the above-mentioned disadvantages, which provides full adhesive effect immediately and which provides better adhesion than conventional tack coating.
- an aqueous emulsion of an asphalt is used as the tack coat.
- Asphalt compound which consists of gravel and asphalt, is made in asphalt plants. From there, the asphalt is driven in trucks to the surfacing site and is dumped into an asphalt laying machine or is laid out manually. The asphalt compound then has a temperature of about 150°C. After this compound has been applied and rolled, it is called asphalt concrete.
- a tack coat is used, as was mentioned above, the composition of which is specified in construction standards.
- the existing asphalt concrete layer is first brushed clean, whereafter the tack coat is spread out by a separate work team with a special separate unit. Then one waits about 1/4 to 3 hours until the water or solvent has evaporated, leaving a thick, sticky asphalt film. Only then is the asphalt compound for the next layer laid out and rolled.
- This binding method only produces an adhesion on the "tops", i.e. a surface adhesion.
- the fresh, hot asphalt compound is applied immediately after the sweeping and the spreading of the tack coat, so that the asphalt compound drops on the wet tack coat film.
- the tack coat is spread in amounts on the order of 0.2-0.4 kg per square meter and has a water content of about 30-50 per cent. This should be compared with the asphalt compound, which has a temperature of about 150°C and which is laid in amounts of about 60-120 kg per square meter.
- the process according to the invention is most suited to tack coats in the form of an aqueous emulsion, but will work for all asphalt binders which are used at present if the amounts of tack coat are adapted to the process.
