Abstract

The invention discloses a process capable of improving clay-bound macadam pavement construction quality in furniture factory pavement construction. Used macadam is formed by rolling hard, durable and clean gravels or rocks, wherein the gravels include natural gravels, break gravels or mixture of the natural gravels and the break gravels and are hard, durable and free from impurities. An appropriate amount of clay is added into a macadam layer and mixed, an appropriate amount of water is added, and paving and compacting are simultaneously performed. The gravels are rolled by a three-wheel roller or vibratory roller when surfaces are dried while insides are semi-wet, calking is blended at any time, and rolling is performed until obvious wheel tracks are avoided and materials are completely stabilized under rolling. In the rolling compaction process, thin stone chips are spread and uniformly swept after rolling compaction is performed for 1-2 times, and rolling compaction is performed so that slurry in gravel gaps floats to the surfaces and is adhered with the spread stone chips into a whole. The process is simple and convenient in course, the pavement construction quality can be ensured, so that a pavement cannot peel in the use process, and the service life is prolonged.

Description

The technique that clay bound macadam construction quality in Furniture Factory's pavement construction can be improved

Technical field

The present invention relates to a kind of technique, more particularly, to one kind clay bound macadam in Furniture Factory's pavement construction can be improved The technique of construction quality.

Background technology

The literal meaning of highway is public road, the road of public's traffic, numerous traffic such as automobile, bicycle, rickshaw, carriage Instrument and pedestrian can walk, and certainly difference highway limits different.Also referred to as road among the people, such as " street angel " inner usage, It is not limited to horses special.There is ordinary highway with expressway other, the latter is more and more, and therefore Class II highway just there are two kinds Specification.

The annual adapted to generally according to the Highway house volume of traffic and its using task and property round the clock, highway is divided into some Industrial grade.What Chinese people's traffic publishing house published in 2004《Highway technical standard》, five skills are divided into highway Art grade.Highway, adapts to annual mechanical transport amount more than 25000 round the clock.Politics with particular importance, Jing Ji meaning, specializes in automobile shunting high speed, continuously drives, and all arranges crossings on different level and control discrepancy, and based on long-distance transport Highway.Class I highway can adapt to annual mechanical transport amount 5000～25000 round the clock, in connecting important politics, economy The heart, towards important industrial and mining area, is available for automobile shunting fast running, part control to come in and go out and partly arrange clover leaf highway. Class II highway adapts to be converted to the annual of the medium-duty truck volume of traffic 2000～5000 round the clock, connection by various vehicles The heavy Highway of suburb of politics, economic center or large-scale industrial and mining area and transport.Class III highway adapts to be converted by various vehicles Annual into medium-duty truck is round the clock below the volume of traffic 2000, and ditch Tong County is public with the general main line in city with county or county Road.Class IV highway adapts to be converted to the annual of medium-duty truck round the clock below the volume of traffic 200 by various vehicles, links up Secondary highway between county and township, town.During highway construction, for the construction on road surface is an important job, tradition Simple, the processing mode without code requirement so that road surface occurs asking in use for some time in the processing procedure of road pavement Topic, causes highway decortication, hole occur and falls into phenomenon, or even cause road to interrupt.

The content of the invention

It is an object of the invention to overcome the above-mentioned existing processing procedure in road pavement simple, the process without code requirement Mode so that road surface goes wrong in use for some time, causes highway decortication, hole occur and falls into phenomenon, or even cause road The problem of interruption, devises a kind of technique that can improve clay bound macadam construction quality in Furniture Factory's pavement construction, the work The process of skill is easy, ensure that construction quality of pavement so that road surface is not in use the phenomenons such as decortication, it is ensured that Service life, it is simple to solve the existing processing procedure in road pavement, the processing mode without code requirement so that road surface exists Using going wrong after a period of time, cause highway decortication, hole occur and fall into phenomenon, or even the problem for causing road interruption.

The purpose of the present invention is achieved through the following technical solutions：Clay bound macadam in Furniture Factory's pavement construction can be improved The technique of construction quality, comprises the following steps：

（1）Rubble used should be hard by quality, durable clean gravel or rock rolling form, should have enough intensity and resistance to Mill performance, building stones intensity is not less than 30Mpa, and the rubble of gravel rolling should have more than 90% crushed particles, and gravel includes natural gravel The compound of stone, cut gravel or gravel by nature and cut gravel, gravel should hard, durable, free from admixture；

（2）Rubble in metalling answers level with well, and maximum particle diameter is not more than 8cm, plus appropriate clay is mixed, and appropriate water mixing, It is compacted in making, it should be noted that roll under optimum moisture content, compactness is not less than 93%；

（3）Pave metaling：Preprepared building stones are once spread into foot by loose laying depth, coefficient of loose laying is 1.2～1.3 or so Paved by the width and thickness of design requirement；

（4）Tentatively roll：The purpose just ground is to roll between gravel particle tightly, but still bag leaves a number of space, so as to mud Slurry can fill, therefore to carry out rolling from vibrated roller being advisable, number of rolling less than 2-4 times, roll to rubble without Loosening situation is degree；

（5）Roll：When surface has been done and inside is still in half wet condition, then continue to grind with three-roll road roller or vibrated roller Pressure, and note that calking is anti-even at any time, directly it is rolled by without obvious wheelmark and under muller till material complete stability, rolling During, after often rolling 1～2 time, that is, spread paving thin layer aggregate chips and sweep even, then rolled, so that the mud in rubble gap is general It is integral with institute chipping bonding to surface；

（6）Quality requirement：Surface should be smooth, solid, must not there is the phenomenons such as loose, spring, after steamroller, must not have bright Aobvious wheelmark, surface layer connects suitable with other structures, must not there is seeping phenomenon, and the road surface apparent size tolerance constructed should meet Relevant code requirement.

In sum, the invention has the beneficial effects as follows：The process of the technique is easy, ensure that construction quality of pavement, makes It is not in use the phenomenons such as decortication to obtain road surface, it is ensured that service life, solves the existing process in road pavement Process is simple, and the processing mode without code requirement so that road surface goes wrong in use for some time causes highway to occur Decortication, hole fall into phenomenon, or even the problem for causing road interruption.
