Abstract
The invention discloses a sealing material for detecting water permeability resistance of an asphalt pavement, belonging to sealing materials. The sealing material for detecting the water permeability resistance of the asphalt pavement is a mixture blended by calcium-based lubricating grease and silicate cement, with calcium-based lubricating grease and silicate cement as raw materials, more preferably 3# calcium-based lubricating grease and 32.5 or 42.5 silicate cement as raw materials; a weight ratio of the calcium-based lubricating grease to the silicate cement is 2:1; and the sealing material is prepared according to the following steps: adding the calcium-based lubricating grease first and then adding the silicate cement into a container by one time; and sufficiently stirring and uniformly mixing the two materials by using a general machine to obtain the sealing material. In use, the sealing material for detecting the water permeability resistance of the asphalt pavement has good water-proof and permeability-resistant effects and has good bonding and sealing performance with the surface of the asphalt pavement.
Description
Technical field
The invention belongs to encapsulant, especially relate to the employed encapsulant of a kind of detection bituminous pavement property.
Background technology
The form of the infiltration of bituminous pavement mostly is the infiltration of horizontal direction, i.e. side direction infiltration, and China's south rainwater is more, and the water permeability resistance of bituminous pavement can seem and particular importance according to the harm of infiltration to bituminous pavement, propose the detection to the bituminous pavement infiltration coefficient; Infiltration coefficient is the index of reflection bituminous pavement impervious outlet capacity, infiltration coefficient be defined as the pavement asphalt layer in certain area with the unit interval in water percolating capacity, the test of infiltration coefficient is a kind of Non-Destructive Testing; In the water penetration test process of bituminous pavement; 1), the 3# calcium grease encapsulant that is adopted directly affects the quality of water penetration test effect, the existing normal encapsulant that adopts:, but this calcium grease is rarer; Make the sealing under the infiltration appearance chassis inhomogeneous; Cause the volume of instrument chassis uncertain, and affect the decline degree of the test water surface, often cause testing result inaccurate; 2), plasticine, but the pliability of plasticine is relatively poor relatively, just is difficult to insert the hole on asphalt pavement structural layer surface, seals also badly, permeable from the asphalt pavement structure hole, often testing result can not truly reflect the permeability performance of bituminous pavement.
Summary of the invention
The objective of the invention is to propose a kind of encapsulant that detects the bituminous pavement water permeability resistance can usefulness, not only easy and simple to handle, raw making materials is easy to obtain, and has the impervious effect of excellent waterproof, with the surface of bituminous pavement good binding and sealing property is arranged.
The objective of the invention is to realize like this: a kind of encapsulant (abbreviation encapsulant) that detects bituminous pavement water permeability resistance ability usefulness; The sealing material is the mix of calcium-base grease and portland cement; Its raw material constituent is calcium-base grease and portland cement; And the raw material constituent is good with 3# calcium-base grease and 32.5 grades or 42.5 grades of portland cements especially, and the weight proportion of this calcium-base grease and portland cement is: portland cement: calcium-base grease=1:2; With these two kinds of materials, add calcium-base grease earlier, after add that portland cement is disposable to add (falling) in container, adopting general facility (instrument) fully to mix is the preparation cost encapsulant.
During use, when promptly the water penetration test of asphalt road detected at the scene, the test surfaces with bituminous pavement cleaned earlier; The position of making and detect that the surface is anhydrous, no-sundries and mark detecting well is uniformly distributed with this encapsulant on the water proof ring that is coated in preset infiltration appearance chassis aligned in position that should be good with mark during the paving water proof ring; In infiltration appearance installation process; Should prevent between this encapsulant circle and the infiltration appearance chassis deviation to take place, should in time correct in case deviation takes place, in the detection; The phenomenon that infiltration appearance chassis, one place periphery seeps water because of encapsulant is not all right does not take place, and makes the one-time detection success ratio reach 100%.
A kind of encapsulant that detects the bituminous pavement water permeability resistance can usefulness proposed by the invention, not only easy and simple to handle, raw making materials is easy to obtain, and has the impervious effect of excellent waterproof, with the surface of bituminous pavement good binding and sealing property is arranged.
Combine at present embodiment to proposed by the invention a kind of detect the bituminous pavement water permeability resistance can with encapsulant be described further.
Embodiment
Embodiment:
When one bid section bituminous pavement scene, road surface, road, big Guangnan, Hubei being carried out the water penetration test detection; Use this encapsulant: according to the weight proportion of calcium-base grease and portland cement; Get 3# calcium-base grease (2 kilograms) and 32.5 grades of portland cements (1 kilogram); Add the 3# calcium-base grease earlier, after add 32.5 grades of portland cements disposable adding (falling) in container, fully mix with cement mortar mixer and process this encapsulant; When the asphalt road water permeability resistance can detect; This encapsulant is uniformly distributed with on the water proof ring that is coated in preset infiltration appearance chassis, during the paving water proof ring with the good aligned in position of mark, in the appearance installation process that seeps water; Deviation does not take place between this encapsulant circle and the infiltration appearance chassis; In this bid section bituminous pavement, done the bituminous pavement seepage test at 60 places, place encapsulant infiltration shape phenomenon does not take place, bituminous pavement seepage test one-time detection success ratio is 100%.
Claims (2)
1. encapsulant that detects the bituminous pavement water permeability resistance can usefulness
, shouldEncapsulant is the mix of calcium-base grease and portland cement, and its raw material constituent is calcium-base grease and portland cement, and the weight proportion of this calcium-base grease and portland cement is: portland cement: calcium-base grease=1:2; With these two kinds of materials, add calcium-base grease earlier, after add that portland cement is disposable to be added in the container, adopting general facility, instrument fully to mix is the preparation cost encapsulant.
