Description

Technical Field

[0001] This application relates to the technical field of highway engineering material testing, and specifically relates to a highway aggregate screening and water washing device. Background Art

[0002] This patent relates to the field of highway engineering material testing. The "Test Regulations for Highway Engineering Aggregates" (JTG E42—2005) clearly requires that aggregates for asphalt mixtures and bases must be screened by the water washing method. However, there is a lack of relevant equipment in the current market, mainly relying on manual hand washing. The soaking solution is alkaline, and the sharp edges and corners of the aggregates are likely to damage the skin. Multiple rinsing and sieving are time-consuming and laborious. There are also some technologies that involve partial operations. For example, some patents involve the dry screening method and cleaning mechanisms, which do not conform to the requirements of the "Test Regulations for Highway Engineering Aggregates" (JTG E42—2005). Some patents involve drying, heating, and sieving mechanisms, but do not involve the water washing method, and still cannot achieve all the requirements of the "Test Regulations for Highway Engineering Aggregates" (JTG E42—2005) by a single machine.
