Description
Technical field：
The present invention relates to technical field of road engineering, and in particular to a kind of bituminous paving water creep appearance under influence of dynamic water and its
Application method.
Background technology：
Automobile will be generated when driving, between tire and road surface on the road surface for thering is moisture film to cover one it is dynamic, instantaneous
Water pressure, i.e. flowing pressure.Moisture, which enters asphaltic road-mix surface course, several main paths, and underground water or rainwater may penetrate soil
Curb, base, median strip or side slope penetrate into face layer；There is different type, different degrees of crack in bituminous paving, when splitting
Slit width degree is more than a threshold value, and rainwater will enter asphaltic road-mix surface course；Rainwater on road surface is under the effect of high speed traveling flowing pressure
Into top course, the Water Damage on road surface is induced.
Detection instrument for current pavement seepage performance is water creep appearance, often occurs some problems in detection process,
In the more serious detection data result that influences be the lateral seepy question of test specimen.
When the invention is applied to solve the above problem of water creep appearance, there are following technical problems：
