Description
Technical field
The utility model relates to a kind of analyser, especially relate to a kind of bituminous pavement and roll analyser, it can be simulated the on-the-spot compacting condition of actual pavement construction, instruct the on-the-spot required number of machine passes of asphalt pavement construction with the number of machine passes of determining, and estimates the road surface usability by the destruction of simulating vehicle load road pavement.
Background technology
How in the on-the-spot compacting situation of laboratory simulation pavement construction, how to simulate the effect of actual vehicle load road pavement, how to carry out the match ratio design according to actual road surface usability, how in the early strength of lab simulation cold recycled asphalt mixture, and the rammability that how could characterize cold recycled asphalt mixture, these all are the problems that the road worker is concerned about.
The case history of failure is told us both at home and abroad: if compactness is not enough, can cause porosity excessive during asphalt concrete construction, porosity is excessive to be the main root that causes the infringement of bituminous pavement early water; Too much can cause and roll if roll number of times, cause the crushed mixture gradation that destroyed of coarse aggregate, will certainly influence the usability of bituminous pavement.Usually the compactness size is to adopt the working-yard to drill through core, calculates compactness or adopts the nucleon density instrument to measure the compactness on road surface with the density of core.Employing drills through core control compactness, can on the road surface that making is good, stay the hole, hole after boring core, the hole, hole will be through repairing, but dropped to normal temperature owing to repair the temperature on protobitumen road surface when cheating the hole, be difficult to be combined into an integral body with hole, hole patching material, hole hole and the surface of contact on protobitumen road surface have just become the weak link on road surface, for the seed of trouble has been buried in the generation of disease; Though adopt the compactness on nucleon density instrument monitoring road surface not need to bore core, but because the close hygronom of nucleon may produce harm to human body, need the special messenger to operate, need to choose a plurality of measurement points in addition in the test process, test speed is slow, and the test data variability is bigger.
The most effective reliable way of usability of estimating the road surface adopts circular track test exactly, but because circular track test expense costliness causes its application limited.In order better to estimate the usability of bituminous pavement, China has successively introduced APA(bituminous pavement analyser) and road surface acceleration charger.Then need special-purpose die trial for APA, load action is when test specimen, and the suffered power in test specimen bottom is born by die trial, and die trial can be regarded rigid body as in loading process, this with actual road surface loading process in basic unit be out of shape and differ greatly.For quickening charger, because it costs an arm and a leg, volume is bigger, and complicated operation does that once the experiment cost is bigger, and it is very few that the whole nation has the unit of this device.
For the simulation of cold recycled asphalt mixture early strength, adopt forming double-layer rut plate usually, after through different conditioned times, health temperature,, characterize the early strength of cold recycled asphalt mixture with the intensity of surveying core by core boring sampling.Water can infiltrate subbase in actual application, adopts this method of double-deck rut twist drill core sampling not consider the effect of subbase to basic unit.
