Abstract

The invention discloses an anti-ponding asphalt pavement construction method which comprises the following steps: S1, construction preparation: comprehensively cleaning the surface of a pavement baselayer on a construction site, blowing off floating ash by arranging 2-3 forest fire extinguishing blowers into an oblique line along the longitudinal direction to ensure that aggregates on the surfaceof the pavement base layer are exposed, and preparing asphalt, aggregates, mineral aggregate and an anti-rut agent; S2, raw material preparation: stirring and mixing asphalt, aggregate, mineral aggregate and an anti-rut agent in a mixing station to obtain an asphalt mixture; s3, measuring and setting out: setting out sample piles along the center line of the pavement base and a quarter of the width of the pavement base, and marking out the paving thickness of the bituminous mixture and a control datum line for guiding the operation trend and elevation of a paver; after the construction methodis adopted, by adding the anti-rut agent, the anti-rut performance of the asphalt mixture is remarkably improved, and meanwhile other performance requirements of the asphalt mixture are met.

Description

Technical field[0001]The invention relates to the technical field of asphalt pavement construction, in particular to a construction method for water-preventing asphalt pavement.Background technique[0002]With the rapid development of the economy and society, the people's demand for quality of travel continues to escalate, and the concept of "environmentally friendly" is increasingly highlighted in transportation construction. In the field of road engineering, how to improve the use function of the road surface and how to provide the society with high-safety, more comfortable and more environmentally friendly road surface characteristics have become the new goals pursued by my country's transportation departments in the new era. Asphalt pavement refers to various types of pavements that are paved with road asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving pellets to resist damage to the pavement caused by driving and natural factors, so that...
