Test device and test method for spillage of asphalt glue

Abstract

The invention discloses a testing device and method of asphalt mastic spillage. The testing device of the asphalt mastic spillage comprises a testing platform, a testing plate, a heating unit, a pressurizing unit, a temperature sensor, an input unit and a control unit, wherein the testing plate is arranged on the testing platform through a lifting drive component; the heating unit is arranged below the testing plate and used for heating the testing plate; the pressurizing unit is arranged above the testing plate and used for pressurizing a to-be-tested sample placed on the testing plate; the temperature sensor is used for measuring the surface temperature of the testing plate; the input unit is used for receiving the testing temperature, testing pressure and testing time which are input bya user. The testing device of the asphalt mastic spillage can measure the asphalt mastic spillage at modified asphalt waterproof roll hot-melting construction joints accurately.

Description

technical field [0001] The invention belongs to the field of building waterproofing, and more specifically relates to a testing device and testing method for asphalt glue spillage. Background technique [0002] At present, in the relevant national construction and acceptance standards, there are clear requirements for modified asphalt waterproofing membranes constructed by hot-melt construction. Among them, item 4.3.8 of "GB50208-2011 Acceptance Code for Underground Waterproof Engineering" stipulates: 1. The flame heater should heat the coiled material evenly, and the coiled material should not be underheated or burned through; 2. The surface of the coiled material should be rolled immediately after melting , Exclude the air under the coiled material, and stick it firmly; 4. The joints of the coiled material should overflow with hot-melt modified asphalt rubber, and stick it firmly and seal it tightly. Article 3 of Item 6.2.6 of "GB50207-2012 Roofing Engineering Quality Acc...

AI Technical Summary

Problems solved by technology

Some manufacturers can use waste rubber powder to modify asphalt to produce qualified products, but the amount of asphalt rubber spilled after fire roasting is small, which cannot meet the construction standards and acceptance specifications

What's more, some manufacturers did not directly add fillers to the modified asphalt to produce products. Although the asphalt glue overflowed a lot after baking, their physical properties were not up to standard, and the waterproof effect could not be guaranteed. There is a lot of glue overflow, which is convenient for construction and misleads the market to a certain extent

[0005] Because both the construction and the performance of the material itself may cause the overflow of asphalt glue at the hot-melt construction joints of the modified asphalt waterproofing membrane to fail to meet the standard requirements, and at this stage there is no special test method and testing instrument for the hot-melt of the modified asphalt waterproofing membrane Test the asphalt glue spillage at the construction joints

If the amount of asphalt glue spillage at the lap joint is unqualified after construction, it is impossible to confirm whether it is a material or construction problem, and disputes are likely to arise
