Description

Be used for ultra-thin wearing layer bituminous concrete material of deck paving and preparation method thereof
Technical field
The present invention relates to a kind of ultra-thin wearing layer bituminous concrete material that is used for deck paving and preparation method thereof, belong to the pavement construction material technical field.
Background technology
Bridge deck pavement mostly adopts the intensive asphalt of joining both at home and abroad at present, and the intensive compound of joining guarantees that in use for bridge deck pavement provides good intensity and stability vehicle steadily crosses.But meanwhile, because pavement material is a close-graded, cause bridge deck pavement to descend at rainy day situation lower surface antiskid, drainage performance, the loss that the annual traffic accident that causes thus causes is quite huge.Therefore design or select ultra-thin asphalt wearing layer with good draining, antiskid function, be laid on bridge deck pavement on, can effectively lower phenomenons such as water smoke, water that rainy day bridge deck pavement driving produces spatter, improve the function of surface of the layer of mating formation, prolong the useful life longevity of bridge deck pavement simultaneously, and then build green traffic, the humane railway and highway system of low-carbon energy-saving environmental protection.
Traditional ultra-thin wearing layer bituminous concrete mostly uses polymer modified asphalt as binder, carry at traffic load, wind, under the influence of factor such as temperature variation, more disease has appearred in ultra-thin wearing layer, most typical disease is exactly dispersing, peel off etc. of tension set and aggregate, cause forfeiture of ultra-thin wearing layer anti-slide performance and drainability to descend, influenced the functional requirement of ultra-thin wearing layer bituminous concrete.
Bituminous epoxy is a kind of thermosetting material, and numerous mechanical index such as its high-temperature stability, low-temperature cracking-resistance, erosion resistance, ageing resistance all are better than other pitch class binders greatly, have favorable durability; The epoxy asphalt concrete construction temperature is low simultaneously, compacting is easy, has tangible environment-friendly advantage.Therefore bituminous epoxy is applied in the bridge floor ultra-thin wearing layer and goes, can effectively solve shortcomings such as ultra-thin wearing layer bituminous concrete high-temperature stability deficiency commonly used, poor durability, prolong the useful life longevity of the ultra-thin wearing layer bituminous compound of bridge floor, also meet the trend and the trend of present road surface energy-conserving and environment-protective.
Therefore, in conjunction with the requirement of the ultra-thin bituminous concrete functions of use of China's bridge floor, the present invention will design a kind of superior round-the-clock cling property that has, the bridge floor ultra-thin wearing layer bituminous concrete of good drainage performance and good durability, improve the surface property of bridge deck pavement, make up a kind of bridge deck pavement material of hommization more.
