New material for road base layer

Abstract

The present invention relates to road building material and is especially a kind of new material for road base layer. The material consists of flyash 65-95 wt%, lime 4-30 wt% and cure agent 0.5-5 wt%; and the cure agent consists of carbonate, chlorate, NaAlO3, MgFSi and Na3SiO3.XH2O. It meets the requirement of protecting environment, has high strength and low cost, and is water resistant and acid and alkali resistant.

Description

technical field [0001] The invention belongs to road building materials, in particular to a new material for road bases. Background technique [0002] At present, the road base materials commonly used at home and abroad are naturally graded crushed stone, notoginseng soil or lime cement plus fly ash plus sandstone aggregate, etc. These materials are either high in cost or low in strength, especially as environmental protection With the strengthening of awareness, taking gravel from mountains will be prohibited. Therefore, it is a problem we need to solve to develop a new road base material that can not only meet the requirements of environmental protection, but also can improve the strength and reduce the cost. Contents of the invention [0003] Purpose of the present invention will solve the deficiencies in the prior art exactly, provide a kind of new material of road base, main component and content are as follows (by...
