Description
Technical field
The utility model belongs to bituminous pavement property valuator device technical field, specifically, relates to a kind of rut temperature control mould of simulated roadway temperature field.
Background technology
Highway in China communication develops rapidly, has made tremendous contribution for promoting modernization construction.But along with the formation of the increase of traffic volume of highway, increase that axle for vehicle carries and canalized traffic, the disease problem of China's bituminous pavement is also more outstanding.At open to traffic, namely part high-grade highway even in two or three years occurs that bellding, cracking, rut etc. damage phenomenon.Wherein, the rut one that problem is the most sharp-pointed in these diseases especially, harm is the most serious, it significantly reduces road surface service life, have impact on traffic safety.Along with highway completes for use, under the effect of the factors such as traffic load, Large Longitudinal Slope, temperature, road speed, ride quality and the service ability of road decline gradually.In recent years, rut has become after Water Damage, causes the pavement disease type of common concern.
Rut is the distinctive a kind of failure mode of bituminous concrete pavement, it is a kind of permanent deformation produced under the combined factors effects such as traffic load repeat function and weather (high temperature), show as and produce longitudinal banded groove along driving wheel mark, time serious, the both sides of rut have projection deformation, cause Pavement Condition more to worsen.In developed country, asphalt pavement rut is an important Con trolling index in bituminous pavement design.In China, the permanent strain of bituminous pavement not yet becomes Pavement Structure Design index, but the high-temperature behavior dynamic stability of compound is the index that must detect.For this reason, China has worked out corresponding High Temperature Stability of Asphalt Mixture evaluation criterion, is intended to improve bituminous pavement high-temperature stability, reduces the harm of rut.
At present, the structure and material integrated design realizing high-temperature behavior is devoted in domestic a lot of research, and car is removed and estimated and control to be the research emphasis of current road circle.But used complete thick formula die trial is that improvement forms on the basis of the thick standard die trial of 300mm × 300mm × 50mm substantially, but do not consider that the temperature field of complete thick formula rut plate under different external condition is on the impact of asphalt pavement rut resisting performance; Also there is some investigators to consider the existence in temperature field, bottom die trial, adopt the method for dynamically immersion that bottom temp is lowered the temperature, but temperature-controllable is poor; Also have some investigators to adopt the way of sealing bed die to realize the thermostatic control of bed die, but cannot accurately realize the requirement of variable ambient temperature field.Therefore, act.std is but difficult to asphalt pavement rut resisting requirement when adapting to varying environment feature and traffic characteristics, or there is the problem of temperature-controllable difference, thus effectively cannot instruct the design and construction of bituminous pavement.
