Abstract
本发明属于公路工程建设与养护领域，具体涉及一种适宜于在低于正常施工温度状态下施工的微表处施工工艺。本发明的技术方案为：矿料：选择优质的玄武岩，添加5%的矿粉，确保提高施工矿料的砂含量大于80%，并且满足MS-3型级配要求；填料：添加矿料质量1~2%的普通硅酸盐325水泥；添加剂为减水和调节拌和时间的乙二醇，添加量为矿料质量的5~10%。本发明就是为了解决特殊情况下的道路养护的微表处工艺。满足微表处在气温在5℃以上和地表温度在10℃以上的施工要求。 The invention belongs to the field of highway engineering construction and maintenance, and in particular relates to a micro-surfacing construction technology suitable for construction at a lower than normal construction temperature. The technical solution of the present invention is: Mineral material: select high-quality basalt, add 5% mineral powder, ensure that the sand content of the construction mineral material is greater than 80%, and meet the MS-3 type gradation requirements; filler: add mineral material quality 1~2% ordinary Portland 325 cement; the additive is ethylene glycol for reducing water and adjusting mixing time, and the amount added is 5~10% of the mass of the mineral aggregate. The present invention aims to solve the micro-surfacing process of road maintenance under special circumstances. It meets the construction requirements of micro-surfacing where the temperature is above 5°C and the surface temperature is above 10°C.
Description
Technical field
The invention belongs to highway engineering construction and maintenance field, be specifically related to a kind of micro-surfacing construction technique of constructing under lower than normal construction state of temperature of being suitable for.
Background technology
Micro-table place is a kind of preventative road maintenance technology of thin overlay.ISSA regulation, temperature lower than 15 ℃, does not allow the construction of micro-table place lower than 10 ℃ and surface temperature.Temperature is seriously restricting the construction period at micro-table place.The present invention designs from material selection, compound design and construction three aspects:.At present, conventional micro-table be in temperature lower than 10 ℃ and surface temperature lower than 15 ℃ of constructions, be not merely to postpone the open to traffic time, even can directly cause project failure, so do not allow the construction of micro-table place.The present invention is exactly in order to solve micro-table place technique of road maintenance in particular cases.Meet micro-table be in temperature more than 5 ℃ and surface temperature at more than 10 ℃ construction requirements.
Summary of the invention
the object of the invention is to overcome above-mentioned technical defect, a kind of micro-surfacing construction technique of constructing under lower than normal construction state of temperature of can being a kind ofly suitable for is provided.
Low temperature micro-surfacing construction technique: described raw material comprises: mineral aggregate, filler, additive, BCR type mulseal; Its Mineral Material is comprised of basalt and breeze: basalt accounts for 95%, and breeze accounts for 5%, and mineral aggregate is got MS-3 type grating, and bitumen aggregate ratio gets 6%; Filler is normal silicate 325 cement, and addition is the 1-2% of mineral aggregate quality; Additive is diminishing and the ethylene glycol that regulates the mixing time, and addition is 5 ~ 10% of mineral aggregate quality; BCR type mulseal is 45% of mineral aggregate quality.
Low temperature micro-surfacing construction technique: described BCR type mulseal is base-material by pitch, emulsifier, water forms, its medium pitch accounts for 55% of mulseal total amount, and wherein institute's emulsifier is cationic emulsifier PION KSD, accounts for 3% of mulseal total amount, alcohols is ethanol, at least one of propyl alcohol or the tert-butyl alcohol, accounts for 10%, and water accounts for 32% of mulseal total amount.
Low temperature micro-surfacing construction technique, concrete steps are:
(1), builder's road road surface must meet the requirement of micro-table place construction;
Before construction, should thoroughly remove earth, the foreign material on former road surface, repair hole groove, depression, the cementation of fissures should be cleared up in wider crack; The appropriate to the occasion spread sticking layer oil in the micro-table of making place on cement concrete pavement, too smooth surface needs plucking to process;
(2), steel wheel rolls;
(3) use 6 ~ 10 tons rubber-tyred roller to breakdown of emulsion just the slurry mixture of one-step forming roll.
modified emulsifying asphalteffect parameter
beneficial effect of the present invention is:the present invention is exactly in order to solve micro-table place technique of road maintenance in particular cases.Meet micro-table be in temperature more than 5 ℃ and surface temperature at more than 10 ℃ construction requirements.
Comparatively speaking, the evaporation of the moisture when molding time on the road surface that makes to construct better adapts to low temperature, better improves the degree of compaction on road surface at short notice for technical scheme of the present invention and conventional micro-table place, and the cryogenic property on the road surface of guaranteeing newly to construct.
Conventional micro-table place and the contrast of the micro-table of low temperature place construction compound technical indicator in the time of 9 ℃
