Description
Technical field
Detection device technology field is the utility model is related to, specifically, there is provided one kind is used to measure dumbbell shaped test specimen
The device of stretching-recoverability.
Background technology
Asphalt is a kind of typical temperature-sensitive material, and the performance of bituminous paving and service life have with temperature
Substantial connection, the crack disease caused by environment temperature such as the high temperature track of bituminous paving, cold cracking is always to perplex state
The main problem of inside and outside road engineering circle.Rubber belongs to elastomer at high temperature, and under the stimulation of temperature, the deformation of generation can for it
To recover.Therefore, there is crack problem to slow down or solve road surface, many researchers propose to fill in asphalt
Rubber, slows down or recovers the crack of bituminous paving generation by using the high resiliency of rubber.In order to determine after having filled rubber
Asphalt Mixture Performance, it is necessary first to know stretching-recoverability of rubber, be currently used for measure rubber recoverability
Method is to observe whether it can be sufficiently spread out after sample is folded mostly, and 100% is returned to original shape；Or by measuring it
Angle is replied to characterize recoverability.In view of in the future by rubber applications to bituminous paving, above-mentioned assay method is only
The property of rubber in itself is merely measured, is not combined it with bituminous paving.Therefore, existing measure rubber recovery
The method of energy can not preferably apply to measure stretching-recoverability of dumbbell shaped rubber.
Utility model content
The purpose of this utility model is that in view of the deficiencies of the prior art, there is provided one kind is used to measure the drawing of dumbbell shaped test specimen
Stretch-the device of recoverability.
