Hybrid asphalt shield pavement protection seal material and preparation method thereof

Abstract

The invention relates to a mixed Lidun pavement protective sealing material which comprises Lidun A and Lidun B, wherein the Lidun comprises a Lidun B liquid and quartz sand, and the Lidun liquid is prepared from an epoxy resin, a reactive diluter, a non-reactive diluter, a coupling agent and a black paste; and the Lidun B comprises a Lidun B liquid and quartz sand, and the Lidun B liquid is prepared from a curing agent and an accelerator. The prepared Lidun protective sealing material adopts the oil solution component, can implement the traditional waterproof antiskid sealing layer, can permeate into the asphalt mixture gaps, can permeate into the aggregate surface pores in the form of molecules, has high and durable binding force with the aggregate, and can generate more obvious binding force on the cement concrete pavement surface.

Description

technical field [0001] The invention belongs to the waterproof and anti-skid protective sealing layer technology for asphalt pavement, cement concrete pavement, bridge deck pavement and tunnel pavement, and in particular relates to a mixed asphalt shield pavement protective sealing layer material and a preparation method thereof. Background technique [0002] The protective sealing layer technology is to use special spraying equipment to mix and spray the protective sealing layer materials at one time or distribute and spray various sealing layer materials on the pavement to form a protective sealing layer of about 1~2mm. The protective sealing layer mainly plays the role of waterproofing, anti-skid, and changing the road capacity for the pavement. At the same time, it can supplement light oil to the aged asphalt, further delaying the further aging of the asphalt, which is beneficial to prolonging the service life of the pavement and appropriately delaying the major and mediu...

Problems solved by technology

[0003] In the 1970s and 1980s, my country began to adopt emulsified asphalt mist seal as a daily maintenance method in the maintenance of municipal roads and local roads. In 2001, it began to introduce asphalt regeneration technology. In recent years, there have been golden bear oil, TL-2000 Technologies such as polymeric pavement strengthening agent, asphalt regeneration, Quadao Asphalt Rehabilitation Agent (CAP), ERA-C asphalt rejuvenation agent, sand-mist sealant, embedded polyurethane anti-skid super surface have emerged successively, but at present these technologies It is difficult to obtain a better balance point in terms of material durability, economy, and construction convenience. Therefore, it is necessary to develop a protective seal material with durable materials, excellent performance, reasonable economy, convenient construction, and low-carbon environmental protection.
