Hot-distribution rubber bituminous pavement and construction method thereof

Abstract

The invention discloses hot-distribution rubber bituminous pavement and a construction method thereof. The construction method comprises the following steps: 1, cleaning a lower bearing layer; 2, preparing rubber asphalt; 3, distributing the rubber asphalt, namely, uniformly distributing a rubber asphalt layer on the lower bearing layer, wherein the distribution amount of the rubber asphalt is 2.2 to 2.6 kg / m<2>, and the distribution temperature is 180 to 190 DEG C; 4, distributing broken stone with an amount which is 60 to 70 percent based on the distribution area of the rubber asphalt, wherein the distribution temperature of the broken stone is not lower than 80 DEG C; and 5, rolling and forming, namely, rolling and forming a rubber asphalt waterproof adhesive layer by a rubber-tire pavement roller following a broken stone distribution vehicle, wherein the rubber-wire pavement roller rolls the pavement once to twice back and forth. The construction method of the invention can enhance the inter-layer adhesive performance, prevent water penetration, effectively absorb and eliminate inter-layer stress and reduce reflection cracks caused by the conventional bituminous pavement, and can be applied to the projects of building and rebuilding bituminous pavement, pavement of bituminous concrete bridge floor, bituminous overlaying of cement concrete pavement and the like.

Description

[0001] technical field

[0002] The invention relates to the field of asphalt pavement construction, in particular to a rubber asphalt waterproof bonding layer and a construction method thereof. Background technique

[0003] The hot-sprinkled rubber asphalt waterproof adhesive layer is a thin layer formed by spraying gravel with a certain particle size immediately after spraying asphalt binder, and then rolling. The main function of the rubber asphalt waterproof bonding layer is to close the small cracks on the surface, prevent water from invading the road surface, and damage the base and roadbed.

[0004] Rubber asphalt is a structural waterproof and bonding material with excellent performance, which can be used as a waterproof, bonding and stress-absorbing functional layer in the asphalt pavement structural layer. The rubber asphalt waterproof bonding layer began to be used in the mid-1960s, and has been widely used in the United States, South Africa, Australia and other ...
