Wood asphalt mixture used for paving side pavement and preparation method thereof

Abstract

The invention relates to a wood asphalt mixture used for paving the side pavement. The wood asphalt mixture is prepared from the following components in parts by weight: 5.0-9.0 parts of base asphalt, 10.0-18.0 parts of coarse woody aggregate, 5.0-15.0 parts of fine woody aggregate, 8.0-15.0 parts of mineral powder and 0.5-1.5 parts of TPS modifier. The invention uses the recycled wood as raw material and the raw material is crushed and pretreated to obtain the aggregate of the mixture; experiments prove that the wood asphalt mixture can meet the demand of the Highway Asphalt Pavement Construction Technical Standard (JTGF40-2004) which is issued by the Ministry of Communications, on the side pavement and non-motorized vehicle roads; and the wood asphalt mixture has the advantages that thewood asphalt mixture has light weight, higher elasticity and recuperative power, heat insulation performance and heat insulation performance, the side pavement paved by the wood asphalt mixture is comfortable to walk, and the wood asphalt mixture can be used in the pavements with low load and a certain demands on the deformability and the walking comfortability such as side pavements and pavements of parks and walking streets.

Description

technical field [0001] This patent relates to a new type of pavement pavement material prepared by using recycled wood as a raw material, crushed and pretreated as a mixture aggregate, and relates to its preparation method. Background technique [0002] In my country's wood processing and wood product manufacturing industries, a large number of scraps and sawdust are produced every year, most of which are dumped as waste or burned as energy, which is a waste of resources and is not conducive to environmental protection. "Waste" is a "resource that has been misplaced". As long as we use it reasonably, it is still a kind of "resource", and wood waste is no exception. According to statistics, my country produces about 60 million tons of waste wood every year, equivalent to 85 million m3 of wood. 3 . Therefore, how to make good use of wood waste has become an important topic before us, which is of great significance. [0003] As early as the early 19th century, the United Sta...
