Problems solved by technology

Although this type of pavement has a certain effect on preventing road surface water and groundwater from damaging the pavement and roadbed, it does not solve the problem for expressways that need timely drainage.

Embodiment 1

[0024] The basic structure of the drainage asphalt pavement in this embodiment is as follows: figure 1 As shown, the pavement layer 1 is a drainage asphalt pavement layer with a thickness of 5-8cm and a porosity of 18%-25%, with a drainage slope greater than 1.5% (preferably controlled at 1.5%-3%) to both sides. Water barrier layer 2 with a thickness of 15-20mm is 0.3-0.5kg / m 2 The modified emulsified asphalt is used to separate the pavement layer 1 from the foundation. The lower part of both sides of the pavement layer 1 has a water collection layer 3 with a thickness of 15-20 cm and a void ratio of 35%-40%. 6 connected. The bottom of the gutter 6 is lower than the catchment layer 3 . The side of the gutter 6 adjacent to the road surface is a curb 4 made of concrete, and a drainpipe 7 is arranged in the ditch. Both sides of the water-resistant layer 2 respectively extend from the bottom of the water-collecting layer 3 to the water-collecting ditch 6 . The water collectin...

Embodiment 2

[0034] The basic situation of this embodiment is basically the same as that of Embodiment 1, the difference is that: the drainage asphalt pavement layer is about 5 cm, and a pavement cushion with a thickness of about 3 cm is also laid between the water-resistant layer, and the pavement cushion is graded according to the following mass percentages Mixed gravel: 100% pass through 16mm sieve, 90-100% pass through 13.2mm sieve, 60-80% pass through 9.5mm sieve, 12-30% pass through 4.75mm sieve, 10-22% pass through 2.36mm sieve Holes, 6-18 through 1.18mm sieve, 4-15% through 0.6mm sieve, 3-12% through 0.3mm sieve, 3-8% through 0.15mm sieve, 2-6% through 0.075mm sieve , so its void ratio is greater than that of the drainage asphalt pavement layer. In this way, the water seepage and drainage effect are better.

[0035] During the rolling process, the initial pressing is 2-3 times at a speed of 1.5-2km / h, the re-pressing is 6-8 times at a speed of 4-5km / h, and the final pressing is 2-...

Abstract

The invention relates to a water-draining type asphalt pavement and a construction method, and belongs to the technical field of road construction. The pavement comprises a pavement layer with an inclination slope for allowing inclined water draining to two sides, and a water-resisting layer for separating the pavement layer from a foundation, water collecting layers with void ratio of 35 percent to 40 percent are arranged at the lower parts of the two sides of the pavement layer, the outer sides of the water collecting layers are communicated with collecting ditches built on two sides of the pavement through declination water seepage holes distributed at intervals, the pavement layer is a water draining asphalt pavement layer with void ratio of 18 percent to 25 percent, the two sides of the water-resisting layer extend to the collecting ditches from the bottom of the water collecting layer respectively, and the bottoms of the collecting ditches are lower than the water collecting layer. According to the invention, the water draining function with penetrating, blocking and draining organically combined can be achieved, splashing and water mist caused by driving in rainy days are enabled to be reduced remarkably, and the favorable visibility is kept.

Description

technical field [0001] The invention relates to a pavement construction method, in particular to a drainage asphalt pavement and the construction method, belonging to the technical field of road construction. Background technique [0002] The problem often encountered when driving on high-speed roads such as expressways in rainy days is that the rain on the road cannot be removed in time, so it is often splashed by the vehicles in front, forming water mist that hinders the line of sight, seriously affecting traffic safety. [0003] With the rapid development of road construction, more and more attention has been paid to the waterproof structure and construction treatment of roads. Chinese invention patents with patent numbers ZL201010132658.X and ZL201010132668.3 respectively disclose two types of waterproof and vibration-damping pavement structures and their construction methods that are basically the same. A waterproof and vibration-damping functional layer is set between...
