Abstract
A road paver includes a screed assembly for laying a mat of paving material, and a tank for storing a coolant. The road paver further comprises a nebulizer device configured to receive the coolant from the tank and to nebulize the coolant into a coolant fog in an environment of the road paver. By cooling the environment of the road paver, the amount of harmful fumes emitted by hot paving material can be substantially reduced.
