Definitions

  • Hydraulic works such as dikes, dams, jetties and breakwaters, are usually subject to severe attack by waves and currents. Fluctuating water levels may also cause loads on the lining of the dam or dike body.
  • the slopes are lined with basalt or concrete blocks or with heavy stones.
  • linings of normally available stones are not always stable enough to withstand the heavy attack by waves and currents. Stabilization against such attack can be obtained by grouting with bitumen or bituminous mixtures so that a water- impermeable structure is obtained.
  • the build-up of a water pressure under the revetment may be caused by the tide, wave suction and as a result of ground water flow.
  • the invention relates to the use of bituminous mixtures for the stabilization against wave and current action of bottom and bank linings of dikes, canals, dams, harbours, beds formed by dropping aggregate, etc. and to the method for applying said mixtures, in such a way that the build-up of a water pressure under the revetment (designated below as lining or covering course) is prevented.
  • the envisaged object may be achieved in a more effective way by using an open mixture of mastic and mineral aggregate.
  • mastic is meant here a mixture of bitumen and filler.
  • Open bituminous mixtures such as for example sand asphalt, generally have insufficient flow properties for good penetration between the stones.
  • certain mixtures of round mineral aggregate and mastic indeed exhibit sufficient flow properties.
  • the use of patches may be dispensed with and complete penetration achieved, while appropriate choice of the mineral moreover gives filter properties to the protecting layer.
  • the invention therefore relates to a method for the stabilization of hydraulic works, such as linings on slopes, dikes, dams, beds formed by dropping aggregate, which contain a covering course of stone, said course being penetrated with a bituminous mixture, characterized in that the bituminous mixture is an open mixture of a mineral aggregate containing round gravel and a mastic asphalt, which mixture penetrates the covering course completely or substantially completely.
  • the invention also relates to a lining thus produced and to a lining which exclusively comprises this bituminous mixture.
  • the lining is preferably at least 30 cm thick and preferably comprises stones having dimensions of at least 20 cm. It is also possible to apply to the bottom a continuous coating of the bituminous mixture, thereby consolidating the subsurface without allowing groundwater pressures to arise.
  • the round gravel which is preferably a round and natural gravel or gravel sand, preferably has dimensions of 0.4-15 mm, in particular 1-8 mm, and is preferably mixed with 4-18% by weight, in particular 6-12% by weight, of mastic asphalt which preferably comprises filler, for example approximately 40-60% by weight, in particular approximately 50% by weight, and approximately 60-40% by weight of bitumen, in particular approximately 50% by weight.
  • a particularly suitable bitumen is road-building bitumen having a penetration of 300-1000, in particular of 5.00-800 (1/10 mm, 25 0 C, 5 sec., 100 g); plasticizers, such as a mineral oil, and other additives may also be added, such as, for example, natural rubber or synthetic rubber, for example thermoplastic rubber of the polystyrene/polyisoprene or polybutadiene/polystyrene type.
  • the mastic asphalt is prepared separately, and the round, heated an dried gravel is subsequently mixed with the mastic asphalt. After mixing at, for example, 90-140°C the mixture is ready and then preferably contains at least approximately 20% of void volume.
  • the stone course is preferably completely penetrated with this hot mixture.
  • the present bituminous mixture is capable of filling the voids between the stones within a reasonable period of time,if necessary under water by cold flow.
  • the method of applying the bituminous mixture may be carried out with a crane, also under water, although preference is given to a method for applying the bituminous mixture under water,'in which use is made of a chute or pipe in which the liquid column present is displaced with the aid of air pressure, the upper part of the chute being provided with an airlock and the lower part preferably with a distributing device.
  • the airlock is preferably a continuously metering airlock, optionally provided with a fixed shaft.
  • the invention also relates to this method as well as to the chute itself.
  • bituminous mixture is passed in an optionally hot condition to just above the point of application as a result of the fact that the liquid column present in the chute is displaced by air.
  • Metering of the bituminous mixture remains possible by using an airlock which preferably operates continuously and which is optionally provided with a fixed shaft.
  • the outlet of the chute is preferably insulated.
  • the chute is preferably provided with a pressure relief device of sufficient capacity, preferably comprising a small- diameter pipe running parallel with the chute, the outlet being approximately 5 cm below the lower extremity of the chute.
