Abstract: A dust-control apparatus may be used in combination with tilling, cultivating, harvesting, construction machinery, and other mobile soil treatment implements. The apparatus applies mist to dust particles where the mist is created by pumping water or other liquid through nozzles. Because the apparatus is used in combination with the operation of the dust-generating machinery, the dust suppressing mist is applied nearly simultaneously to the generation of the dust by the agitation of the soil by the machinery. In one embodiment of the device, the operation of the pump or valves which control liquid flow to the nozzles is automatically activated by a optical sensor. The optical sensors cause either the starting of a pump or opening of a valve thereby increasing or decreasing the pressure and/or volume of the liquid upon the dust level reaching a preset trigger point as detected by the sensor.

Abstract: The present invention provides a method and pavement structure for protecting highway subgrade in frozen soil areas. The pavement structure has two or more pavement layers having gradient thermal conductivity; the thermal conductivity is layered among the pavement layers and is lowered from top to bottom, so that the pavement forms a uni-directional thermal conducting tunnel from the subgrade to the air. Heat can be easily released from the subgrade into the air, and is prevented from being transferred from the air to the subgrade. In this way, the frozen soil layer beneath the subgrade is cooled, so that the frozen soil table is made stable, and the highway subgrade in frozen soil areas is protected.
