Description
Technical Field
The utility model relates to a detection device, concretely relates to semi-flexible road surface grouting material shrinkage test device.
Background
The semi-flexible pavement is a new pavement structure form, which is a rigid and flexible composite pavement formed by pouring high-fluidity cement-based materials into a large-gap asphalt concrete pavement. Compared with the common asphalt pavement, the semi-flexible pavement has higher rigidity and is easy to generate shrinkage cracks in the early stage, so the detection of the shrinkage performance of the grouting material is particularly important.
In the existing standard and common test methods, the mortar related test method in the building industry is mostly used for reference about the drying shrinkage performance test of the cement-based material, and the test device comprises: a comparator, a vertical contraction meter and the like. The test devices can not well reflect the practical application condition of the pavement material in the highway engineering and can not truly reflect the transverse shrinkage development rule of the cement-based grouting material of the semi-flexible pavement.
SUMMERY OF THE UTILITY MODEL
The utility model provides a semi-flexible road surface grouting material shrinkage test device can detect out road surface material operating condition well, has easy and simple to handle, the accurate, reliable advantage of conclusion of data.
The technical scheme of the utility model as follows:
a semi-flexible pavement grouting material shrinkage test device comprises a base bottom plate, side plates, a pair of lever type dial gauges, an outer hexagonal screw and a glass rod, wherein the two side plates are symmetrically and respectively vertically arranged at two ends of the base bottom plate, the side plates are provided with a circular fixing hole and a vertical threaded hole, the vertical threaded hole is communicated with the circular fixing hole, a gauge rod of the lever type dial gauge is placed in the circular fixing hole, and the outer hexagonal screw is screwed into the vertical threaded hole and positions the gauge rod of the lever type dial gauge; the plurality of glass rods are placed on the base bottom plate and used for supporting a test piece; the hands of a pair of lever-type dial gauges are used to test a test piece placed therebetween.
The preferable scheme of the semi-flexible pavement grouting material drying shrinkage test device is that the glass rod is in a smooth cylindrical shape.
The semi-flexible pavement grouting material drying shrinkage test device has the preferred scheme that the base bottom plate and the side plates are connected into a whole in a welding mode.
The utility model has the advantages that: when the testing device of the utility model is used, after the semi-flexible pavement grouting material test block expands or contracts, the lever type dial indicator obtains the contraction and expansion length of the test block by detecting the displacement of the test block; simultaneously, fix the lever amesdial through circular fixed orifices, vertical screw hole and outer hexagonal screw, avoid the slip of lever amesdial to the influence of testing result. Support the test piece through a plurality of glass stick, guarantee that the test piece can freely remove under the dry shrinkage effect, avoid the adhesion of test piece on base bottom plate surface, influence and detect the precision.
