Description
Technical field
The present invention relates to the test method of Expressway Pavement Material, especially relate to a kind of test instrument, the invention still further relates to the quantitative test method of using this test instrument to test the coating emulsified asphalt permeance property.
Background technology
Highway in China generally adopts semi-rigid type base as the main bearing stratum of pavement structure at present, and from now on large-scale application will arranged.Because semi-rigid sub-base material is different from the chemical attribute of asphalt pavement material, need to adopt the interlaminar bonding problem that solves semi-rigid type base and asphalt concrete pavement in the method for the saturating coating emulsified asphalt of semi-rigid type base surface spreading, as a whole to guarantee that asphalt mat and semi-rigid type base better are combined into, prevent that infringement from appearring in bituminous pavement, thereby prolong the life-span of bituminous pavement, improve the permanance of bituminous pavement.Therefore, the permeance property of coating emulsified asphalt is to affect the bituminous pavement key factor in serviceable life thoroughly.
Because therefore the coating emulsified asphalt permeance property, needs the test method of the saturating coating emulsified asphalt permeance property of research and development to the material impact of Pavement of Asphalt Road Performance thoroughly.Although the present more domestic test method that emulsified asphalt permeance properties are arranged, all take the raw-material analysis and research of high infiltration emulsified asphalt as the basis, test method is not mature enough in the great majority test.The test method of emulsified asphalt permeance property commonly used mainly contains following three kinds at present:
(1) according to traditional saturating coating emulsified asphalt of production technology spreading, by getting core, observes the permeance property of priming oil;
(2) with normal sand: cement: water prepares cylinder specimen in the 20:1:1 ratio, and a certain amount of coating emulsified asphalt of spreading on test specimen is after the certain hour infiltration, by the permeance property of observe and decide priming oil;
(3) preparation standard semi-rigid type base test specimen (plate test coupon of 30cm * 30cm * 10cm), the permeance property of observing priming oil by the saturating coating emulsified asphalt of spreading on test specimen.
The first test method need to be tested by enterprising line correlation on actual road surface, though can intuitively reflect the permeance property of emulsified asphalt, need to be at actual road surface core detection, and the test period is long, the discreteness of test findings is large, and the integrality of basic unit has been caused certain destruction; Although the second test method can be carried out indoor, convenient and swift, the impact of human factor is larger in the process of the test; The third test method is difficult to reach the compactness on actual road surface because the height of shaping test piece is limited, and the porosity of shaping test piece is larger than actual road surface, test result and actually differ larger.Therefore, the permeance property that adopts above these test methods to estimate emulsified asphalt all has certain defective, be necessary to research and develop the test instrument of the saturating coating emulsified asphalt permeance property of a kind of indoor quantitative evaluation, evaluation quick, accurate to the emulsified asphalt permeance property to realize, that quantize.
Summary of the invention
The object of the present invention is to provide a kind of saturating coating emulsified asphalt permeance property test instrument easy to operation; The present invention also provide use this test instrument efficient, stable in the indoor method that saturating coating emulsified asphalt permeance property is carried out quantitative test.
For achieving the above object, the present invention can take following technical proposals:
Test instrument of the present invention, it comprises base and the pole that is vertically set on the described base, be placed with permeable stone at described base, the sleeve that button is placed on the described base coats described permeable stone wherein, be placed with glass tube in described sleeve interpolation, the lower edge of described glass tube is attached to the upper surface of described permeable stone; Be placed with funnel in the horizontally disposed funnel set collar on described pole, the discharging opening of described funnel is corresponding with the center of described glass tube.
For guaranteeing the osmotic effect of emulsified asphalt, the middle part of described permeable stone offers circular groove, and the lower edge of described glass tube embeds in the circular groove of described permeable stone.
Regulate for convenient, described funnel set collar is movably arranged on the described pole by fastening bolt.
Described sleeve is up-small and down-big step barrel structure.
For realizing the infiltrative quantitatively evaluating of emulsified asphalt, use the infiltrative method of above-mentioned test instrument test emulsified asphalt as follows:
The first step, Application standard sieve sieves the homogeneous sand of dried and clean, and the standard volume sand of getting particle diameter and be 0.15-0.30mm collects, and leaves in the dry environment for subsequent use;
Second step, the standard volume sand that the particle diameter that the first step is sieved out is qualified is put into baking oven, dries to constant weight under 25 ℃ of constant temperatures; Each parts of test instrument are also put into 25 ℃ of constant temperature oven preheatings to be installed for subsequent use after 30 minutes;
The 3rd step, under 25 ℃ of conditions, funnel is vertically put into the funnel set collar, adjust the position of funnel set collar, make the funnel discharging opening apart from the permeable stone upper surface 105mm of glass tube bottom, then by funnel in the glass tube disposable slowly at the uniform velocity adding second step drying and processing to the standard volume sand 50g of constant weight;
The 4th step, take off funnel from the funnel set collar, gently the standard volume sand in the glass tube is flattened with the leveling bar of bottom with disk;
The 5th step, measure the emulsified asphalt solution of 10g, by funnel it is drained on the standard volume sand in the glass tube;
The 6th step, begin to use manual time-keeping from emulsified asphalt solution contact standard volume sand surface, the record emulsified asphalt all infiltrates the time T (s) in the permeable stones from glass tube, according to the seepage discharge M(g of emulsified asphalt in amount sand), calculate the infiltration coefficient C of emulsified asphalt
Ea=M/T(g/s).
Infiltration coefficient C
EaRepresent the infiltration capacity of unit interval internal emulsification pitch; infiltration coefficient is larger; emulsified asphalt effect in actual applications is just better, and namely behind the spreading emulsified asphalt of semi-rigid type base surface, the degree of depth of infiltration is darker; more can effectively protect the moisture loss of basic unit; be conducive to the raising of foundation base intension, avoid basic unit to wreck in construction period, more be conducive to strengthen the bonding between basic unit and the surface layer; make basic unit, surface layer form an integral body, thereby prolong the serviceable life on road surface.
The invention has the advantages that and utilize test instrument simple in structure, easy and simple to handle, efficient stable, accurately simulated the osmotic effect of saturating coating emulsified asphalt use in basic unit, thereby realized the infiltrative quantitatively evaluating of emulsified asphalt; Guarantee to use the interlaminar bonding problem of coating emulsified asphalt secure bond semi-rigid type base and asphalt concrete pavement, guaranteed the serviceable life of bituminous pavement.
