Quick determining instrument for water content of pavement material containing pitch milling material

Abstract

The invention discloses a quick determining instrument for water content of a pavement material containing a pitch milling material and belongs to the field of road engineering detection equipment. The structure thereof comprises a drying drum, a rotation driving mechanism, a hot air mechanism and a controller, wherein the drying drum is used for supplying a container for drying to a to-be-detected pavement material; the rotation driving mechanism is used for supplying power to the drying drum and rotating the drying drum along the peripheral direction thereof; the hot air mechanism is used for supplying heat source for heating and drying the to-be-detected pavement material; the rotation driving mechanism and the hot air mechanism are both electrically connected with the controller. Compared with the prior art, the quick determining instrument for water content of the pavement material containing the pitch milling material disclosed by the invention has the advantages of capability of realizing onsite detection, characteristics of high detection speed and accurate detection result, capability of supplying equipment support for control on the compactness of the pavement and real-time monitoring for the compactness and high popularization and application values.

Description

technical field [0001] The invention relates to the field of road engineering testing equipment, in particular to a quick measuring instrument for moisture content of asphalt-containing milling and planing pavement materials. Background technique [0002] Asphalt-containing milling materials mainly include three types, cement-stabilized semi-rigid base material containing asphalt milling materials, emulsified asphalt cold recycled mixture, and foamed asphalt cold recycled mixture. Among them, the cement-stabilized semi-rigid base material containing asphalt milling material is a pavement road construction material that mixes the surface layer milling material into the cement-stabilized base. The moisture content of the traditional cement-stabilized base is measured on site. The combustion method is used for determination, but the combustion method cannot be used for asphalt-containing milling materials, because the combustion method will cause the asphalt inside the mixture ...

Problems solved by technology

Among them, the cement-stabilized semi-rigid base material containing asphalt milling material is a pavement road construction material that mixes the surface layer milling material into the cement-stabilized base. The moisture content of the traditional cement-stabilized base is measured on site. It is determined by combustion method, but the combustion method cannot be used for asphalt-containing milling materials, because the combustion method will cause the asphalt inside the mixture to be burned, resulting in unnecessary errors

For emulsified asphalt cold recycled mixture and foamed asphalt cold recycled mixture, the water content of the construction site can only be detected by drying method, which takes a long time period and cannot guide the construction on site in real time
