Asphalt elongation collecting device

Abstract

The invention provides an asphalt extensibility collecting device which comprises a machine body, self-locking universal wheels, a testing groove, a telescopic column and a control console, fixing seats are fixedly installed at the two ends of an inner cavity of the testing groove, first limiting columns are fixedly welded to the surfaces of the fixing seats, motors are fixedly installed on one sides of the fixing seats, sliding grooves are formed in the two sides of the inner wall of the testing groove, moving seats are slidably installed in inner cavities of the sliding grooves, second limiting columns are welded to the surfaces of the moving seats, the surfaces of the first limiting columns and the surfaces of the second limiting columns are sleeved with testing molds, and mold grooves are formed in inner cavities of the testing molds. In the using process, asphalt of different sizes and the extensibility of the asphalt at different temperatures can be collected, the collecting function is more comprehensive, the collecting precision is higher, the water temperature problem does not need to be considered when the testing mold is taken out, and using is more convenient.

Description

technical field [0001] The invention relates to the technical field of asphalt elongation testing, in particular to an asphalt elongation acquisition device. Background technique [0002] Asphalt extensometer is an instrument suitable for measuring asphalt ductility and elastic recovery test of modified asphalt. The specific operating procedures are as follows: [0003] (1) The instrument should be placed horizontally indoors, with a temperature of 0°C to 40°C, a relative humidity of no more than 80%, no vibration, no corrosive gas, and good grounding protection. (2) Before use, check the water level in the water tank, which should meet the requirements of the test operating procedures. After turning off all function switches, turn on the power, and check whether the stirring motor and the extension power motor are running well. (3) Adjust the temperature controller to the required temperature. According to the test requirements and ambient temperature requirements, start t...

AI Technical Summary

Problems solved by technology

[0004] However, the existing asphalt elongation collection device has a fixed size of the test mold during use, and cannot test different volumes of asphalt during use, and its function is relatively single. At the same time, when the test mold is taken out of the water, The water temperature may be too cold or overheated, so that the operator cannot quickly remove the test mold
