Embodiment Construction

[0018] The present invention will be further described below in conjunction with embodiment:

[0019] An asphalt pavement comprises an upper layer, a middle layer and a pavement base layer, the upper layer and the middle layer are SBS-T modified asphalt, and the pavement base layer is made of concrete, emulsified asphalt and water. The thickness of the pavement base layer is 20-25cm. The thickness of the upper layer is 10-15cm. The thickness of the upper layer is 15-18cm. The ratio of SBS-T to emulsified asphalt in the upper layer is 1:25. The ratio of SBS-T to emulsified asphalt in the middle surface layer is 1:15. The ratio of concrete, emulsified asphalt and water in the pavement base is 15:1:1.

[0020] An asphalt pavement, comprising the following construction steps:

[0021] Step 1: Pave the pavement base layer, lay the mixture of concrete, emulsified asphalt and water, and use the paving machine to pave the pavement base layer. The paving speed of the paving machin...

Abstract

The invention discloses an asphalt pavement and a construction method thereof. The asphalt pavement comprises an upper surface course, a middle surface course and a pavement base course; the upper surface course and the middle surface course are SBS-T modified asphalt; the pavement base course is made of concrete, emulsified asphalt and water; and the construction method comprises the steps of laying the pavement base course, carrying out initial pressing, re-pressing and final pressing on the pavement base course, laying the middle surface course, carrying out initial pressing, re-pressing and final pressing on the middle surface course, laying the upper surface course, carrying out initial pressing, re-pressing and final pressing on the upper surface course, and curing the upper surfacecourse.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an asphalt pavement and a construction method thereof. Background technique [0002] Asphalt pavement refers to various types of pavement paved with asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving aggregates to resist road damage from driving and natural factors, making the road smooth, less dusty, impermeable and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction. However, the existing asphalt pavement has a short service life, and reflective cracks are prone to occur after a period of use, which brings a lot of inconvenience to the use. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides an asphalt pavement and a construction method thereof, aiming at solving the problem of reflective cracks on t...
