Description

本発明は、アスファルト舗装された駐車スペースの舗装構造に関する。 The present invention relates to a pavement structure for an asphalt-paved parking space.

従来から、車両の駐車場の舗装構造は、表面に密粒度アスファルトを舗装して車輪の摩耗による劣化を防ぐと共に、排水溝に向けて表面に勾配を付けて雨水等による水たまりの発生を防いでいた。例えば、一般的な住宅における普通自動車一台の駐車スペースは、幅２．５ｍ～３ｍ程度、奥行５ｍ～６ｍ程度であり、道路側（手前側）の排水溝に向けて奥側から１．５％～２％程度の勾配を設けて雨水を排水溝に流していた。 Conventionally, the pavement structure of vehicle parking lots has consisted of a dense-grained asphalt surface to prevent deterioration due to wheel wear, and a slope on the surface toward the drainage ditch to prevent the formation of puddles due to rainwater, etc. For example, a parking space for one standard-sized car in a typical residential building is about 2.5m to 3m wide and 5m to 6m deep, with a slope of about 1.5% to 2% from the back toward the drainage ditch on the road side (nearby) to allow rainwater to flow into the drainage ditch.

また、特許文献１には、地下駐車場等の舗装構造として、地盤に対して上から順に、密粒アスファルト層と、透水アスファルト層とを積層し、地盤から浸透する地下水を透水アスファルト層を介して湧水槽に排水する技術が開示されている。この構成によれば、単に密粒アスファルト層及び透水アスファルト層からなる二重構造とするだけで、地下に設けていた排水溝が不要となり、設計及び施工における作業量やコストの低減化を期待できるという。 Patent Document 1 also discloses a technology for paving underground parking lots and the like, in which a dense-grained asphalt layer and a water-permeable asphalt layer are layered on top of the ground, and groundwater that seeps through the ground is drained into a spring water tank through the water-permeable asphalt layer. With this configuration, simply creating a double structure consisting of a dense-grained asphalt layer and a water-permeable asphalt layer eliminates the need for underground drainage ditches, and is expected to reduce the amount of work and costs involved in design and construction.

特開平１１－１０７２９６号公報Japanese Patent Application Laid-Open No. 11-107296

特許文献１に示すような透水性アスファルトは、密粒度アスファルトより空隙が多い分、水を浸透させやすい反面、摩耗しやすいため、密粒度アスファルトより耐久性が低い。したがって、特許文献１や透水性アスファルトに関する公知技術に基づき、駐車場の表面の舗装に密粒度アスファルトと透水性アスファルトとを併用することは、当業者にとって容易ではない。 Permeable asphalt such as that shown in Patent Document 1 has more voids than dense-graded asphalt and therefore allows water to penetrate more easily, but it is more susceptible to wear and therefore less durable than dense-graded asphalt. Therefore, based on Patent Document 1 and the publicly known technology related to permeable asphalt, it is not easy for a person skilled in the art to use both dense-graded asphalt and permeable asphalt in paving the surface of a parking lot.

また、駐車場のように車両のハンドル操作が多めの場所では、車輪の旋回により表面が削れてしまうため、透水性アスファルトは不向きである。しかしながら、透水性アスファルトを採用すれば、表面に勾配を付けなくてもよいため、排水溝の場所に依存しない分、駐車場の舗装負担が軽減する効果を期待できる。すなわち、駐車スペースの表面の舗装に密粒度アスファルトと透水性アスファルトとを併用する価値がある。 Also, permeable asphalt is not suitable for places such as parking lots where vehicles are turned frequently, because the surface is worn away by the turning of the wheels. However, if permeable asphalt is used, there is no need to slope the surface, and it is expected that the burden on the parking lot pavement will be reduced since it is not dependent on the location of the drainage ditches. In other words, it is worth using a combination of dense-graded asphalt and permeable asphalt to pave the surface of parking spaces.

そして、発明者は、密粒度アスファルトと透水性アスファルトとを併用して双方の利点を活かすために、駐車スペースと駐車する車両との関係に着目した。すなわち、車両一台分に相当する駐車スペースのうち、車両の仕様に鑑みて、耐久性を優先すべき部分と透水性を優先すべき部分とを分け、それぞれの部分を密粒度アスファルトと透水性アスファルトとで舗装すれば、双方の利点を活かし、欠点を最小限に抑えられる点に辿り着いた。 The inventor then focused on the relationship between parking spaces and parked vehicles in order to utilize the advantages of using dense-graded asphalt and water-permeable asphalt together. In other words, he discovered that by dividing a parking space equivalent to the size of one vehicle into areas where durability should be prioritized and areas where water permeability should be prioritized, taking into account the vehicle's specifications, and paving each area with dense-graded asphalt and water-permeable asphalt, it would be possible to utilize the advantages of both and minimize the disadvantages.

そこで、本発明の目的は、アスファルトの特性及び駐車スペースと車両との相関を活かし、使用上好ましい耐久性及び透水性を備え、従来と比べて施工の負荷を軽減できる舗装構造を提供することにある。 The object of the present invention is to provide a pavement structure that takes advantage of the characteristics of asphalt and the correlation between parking spaces and vehicles, has favorable durability and permeability for use, and reduces the burden of construction compared to conventional methods.

すなわち、本発明における舗装構造は、車両一台分の駐車スペースの舗装構造であって、密粒度アスファルト部と、透水性アスファルト部とを含むアスファルト部を備え、上記密粒度アスファルト部は、上記駐車スペースに駐車時の車両の駆動輪の真下に位置し、上記透水性アスファルト部は、上記車両の乗降口に沿って位置している。 In other words, the pavement structure of the present invention is a pavement structure for a parking space for one vehicle , and comprises an asphalt section including a dense-grained asphalt section and a water-permeable asphalt section, wherein the dense-grained asphalt section is located directly beneath the drive wheels of the vehicle when parked in the parking space, and the water-permeable asphalt section is located along the entrance and exit of the vehicle.

上記車両は、前輪駆動の普通自動車であり、上記密粒度アスファルト部は、上記駆動輪を含む上記車両の前方側に位置し、上記透水性アスファルト部は、上記乗降口を含む上記車両の後方側に位置している。 The vehicle is a front-wheel drive passenger vehicle, and the dense-grained asphalt section is located at the front of the vehicle, including the drive wheels, and the permeable asphalt section is located at the rear of the vehicle, including the boarding and alighting entrance.

上記密粒度アスファルト部と上記透水性アスファルト部とは、隣接しており、少なくとも上記密粒度アスファルト部の表面部分と上記透水性アスファルト部の表面部分とは、異なる色を有する。 The dense-graded asphalt portion and the water-permeable asphalt portion are adjacent to each other, and at least the surface portion of the dense-graded asphalt portion and the surface portion of the water-permeable asphalt portion have different colors.

本発明による舗装構造によれば、アスファルトの特性及び駐車スペースと車両との相関を活かし、使用上好ましい耐久性及び透水性を備え、従来と比べて施工の負荷を軽減できる。 The pavement structure of the present invention takes advantage of the characteristics of asphalt and the correlation between parking spaces and vehicles, provides desirable durability and water permeability, and reduces the burden of construction compared to conventional methods.

＜本舗装構造の概要＞
図１に示すように、本舗装構造は、アスファルト舗装されたものであり、少なくとも密粒度アスファルト部１と、透水性アスファルト部２とを含むアスファルト部Ｒａを備え、密粒度アスファルト部１は、駐車スペースＰに駐車時の車両Ｃの駆動輪として、例えば、前輪Ｔｆ周辺に位置しているが、後輪Ｔｒ周辺又は双方周辺に位置していてもよく、透水性アスファルト部２は、車両Ｃの乗降口Ｄ周辺に位置している。 <Outline of this pavement structure>
As shown in Figure 1, this pavement structure is an asphalt pavement and comprises an asphalt section Ra including at least a dense-grained asphalt section 1 and a water-permeable asphalt section 2, and the dense-grained asphalt section 1 is located, for example, near the front wheels Tf as the drive wheels of the vehicle C when parked in the parking space P, but may also be located near the rear wheels Tr or both, and the water-permeable asphalt section 2 is located near the boarding and alighting entrance D of the vehicle C.

この構成によれば、車両Ｃのハンドル操作に連動して駆動輪が相対的に旋回する範囲に密粒度アスファルト部１を舗装するため摩耗による劣化を予防し、相対的に車両Ｃに乗ったり車両Ｃから降りたりする範囲に透水性アスファルト２を舗装するため水たまりの発生を予防でき、換言すれば、駐車スペースと車両との相関に応じてアスファルト舗装するため所望の耐久性及び透水性を実現できる上に、排水用の勾配を設けなければその分の施工負荷を軽減でき、さらに補修作業の頻度や程度を抑える効果を期待できる。 With this configuration, the dense-grained asphalt section 1 is paved in the area where the drive wheels turn relatively in conjunction with the steering operation of the vehicle C, preventing deterioration due to wear, and the permeable asphalt 2 is paved in the area where the vehicle C is entered and exited relatively, preventing the formation of puddles. In other words, the asphalt pavement is laid according to the correlation between the parking space and the vehicle, achieving the desired durability and permeability, and in addition, the construction load can be reduced by not providing a drainage slope, and the effect of reducing the frequency and extent of repair work can be expected.

具体的に、車両Ｃは、前輪駆動の普通自動車であり、密粒度アスファルト部１は、駆動輪である前輪Ｔｆを含む車両Ｃの前方側に位置し、透水性アスファルト部２は、乗降口Ｄを含む車両Ｃの後方側に位置している。車両Ｃの前方側及び後方側とは、駐車スペースＰの手前（車道）側又は奥（車庫）側であるが、どちらとも車道側でもよい。密粒度アスファルト部１は、乗車口Ｄのうち運転席及び助手席より車両Ｃの前方側の全部又は一部でもよく、透水性アスファルト部２は、乗降口Ｄのうち後部座又は後輪Ｔｒより車両Ｃの後方の全部又は一部でもよい。 Specifically, vehicle C is a front-wheel drive passenger vehicle, and dense-graded asphalt portion 1 is located at the front side of vehicle C, including the front wheels Tf, which are the drive wheels, and water-permeable asphalt portion 2 is located at the rear side of vehicle C, including the boarding/alighting entrance D. The front and rear sides of vehicle C refer to the front (roadway) side and rear (garage) side of parking space P, but both may be the roadway side. Dense-graded asphalt portion 1 may be all or part of the boarding entrance D, which is forward of the driver's seat and passenger seat, and water-permeable asphalt portion 2 may be all or part of the boarding entrance D, which is rear of vehicle C, including the rear seat or rear wheels Tr.

この構成によれば、一般的に普及率の高い前輪駆動の普通自動車に適した駐車スペースの舗装構造を提供できる。すなわち、密粒度アスファルト部１は、意図的に前輪Ｔｆを旋回させても摩耗しにくく、透水性アスファルト部２は、運転席・助手席・後部座席の乗降口周辺に水たまりを発生しにくくできるため、舗装構造の劣化のみならず、雨天時の乗り降りの負担を軽減する効果を期待できる。 This configuration provides a pavement structure for parking spaces suitable for standard front-wheel drive automobiles, which are generally widely used. In other words, the dense-graded asphalt portion 1 is resistant to wear even when the front wheels Tf are intentionally turned, and the water-permeable asphalt portion 2 makes it difficult for puddles to form around the driver's seat, passenger seat, and rear seat entrances, which is expected to not only prevent deterioration of the pavement structure but also reduce the burden of getting in and out of the car in rainy weather.

また、密粒度アスファルト部１と透水性アスファルト部２とは、隣接しており、少なくとも密粒度アスファルト部１の表面部分と透水性アスファルト部２の表面部分とは、異なる色を有する。換言すれば、密粒度アスファルト部１と透水性アスファルト部２との境界は面一であり、表面部分の色は同じか似ていてもよい。 The dense-graded asphalt portion 1 and the water-permeable asphalt portion 2 are adjacent to each other, and at least the surface portion of the dense-graded asphalt portion 1 and the surface portion of the water-permeable asphalt portion 2 have different colors. In other words, the boundary between the dense-graded asphalt portion 1 and the water-permeable asphalt portion 2 is flush, and the colors of the surface portions may be the same or similar.

この構成によれば、密粒度アスファルト部１と透水性アスファルト部２とを略同時期に舗装しやすいため施工の負荷を軽減できるのみならず、運転手は駐車スペースに対して車両Ｃを位置決めしやすくなるためスムーズに駐車でき、アスファルト部Ｒａの劣化も低減できる効果を期待できる。 This configuration not only reduces the burden of construction by making it easier to pave the dense-graded asphalt section 1 and the water-permeable asphalt section 2 at roughly the same time, but also makes it easier for the driver to position the vehicle C relative to the parking space, allowing for smoother parking, and is expected to reduce deterioration of the asphalt section Ra.

＜本舗装構造の詳細＞
図１に示すように、本舗装構造は、駐車スペースの表面に該当するアスファルト部Ｒａと、アスファルト部Ｒａの下位にある路盤Ｒｂとを、舗装を支持する地盤に相当する路床Ｒｃに積層したものである。アスファルト部Ｒａは、アスファルト混合物で形成され、最上位にある図示しない表層と、表層の下位及び路盤Ｒｂの上位にある図示しない基層とを積層したものでもよく、厚さは３０ｍｍ～５０ｍｍ程度でもよく、排水用の勾配を有していてもいなくてもよい。 <Details of this pavement structure>
As shown in Figure 1, this pavement structure is formed by stacking an asphalt section Ra, which corresponds to the surface of the parking space, and a roadbed Rb, which is below the asphalt section Ra, on a roadbed Rc, which corresponds to the ground supporting the pavement. The asphalt section Ra is made of an asphalt mixture, and may be a stack of a top surface layer (not shown) and a base layer (not shown) below the surface layer and above the roadbed Rb, and may have a thickness of about 30 mm to 50 mm, and may or may not have a slope for drainage.

一般的に、「表層」は、磨耗しにくく、平坦で滑りにくく、かつ車両を走行しやすくするものであり、「基層」は、路盤Ｒｂの不陸を整正すると共に、表層に加わる荷重を路盤Ｒｂに均一に伝達するものであり、「路盤」は、荷重を路床Ｒｃの支持力の許容範囲内に抑えて伝えるものであり、「表層」や「基層」を形成するアスファルト混合物は、結合材としてのアスファルトと、砕石や砂利といった骨材、石粉や消石灰といったフィラーと、を所定の割合で配合したものであり、所定の骨材粒度に調整して加熱した後、ミキサー等でアスファルトと混合して生成される。 In general, the "surface layer" is resistant to wear, flat, non-slip, and easy for vehicles to travel on, the "base layer" corrects unevenness in the roadbed Rb and transmits the load applied to the surface layer evenly to the roadbed Rb, and the "roadbed" transmits the load while keeping it within the allowable range of the bearing capacity of the roadbed Rc. The asphalt mixture that forms the "surface layer" and "base layer" is a mixture of asphalt as a binder, aggregate such as crushed stone or gravel, and filler such as stone powder or slaked lime in a specified ratio, which is adjusted to the specified aggregate particle size and heated, and then mixed with asphalt in a mixer or the like to produce the product.

密粒度アスファルト部１及び透水性アスファルト部２は、上記アスファルト混合物と略同等であるが、透水性アスファルト部２は、密粒度アスファルト部１と比べて、骨材のうち細骨材が少なく、粗骨材が多く、結合材であるアスファルトの使用量も少なく、舗装の空隙率が多いものであり、具体的には、水、アスファルト、細骨材、粗骨材、化学混和剤、及び硬化調整剤を所定の割合で配合したものである。 The dense-graded asphalt portion 1 and the water-permeable asphalt portion 2 are approximately equivalent to the asphalt mixture described above, but compared to the dense-graded asphalt portion 1, the water-permeable asphalt portion 2 contains less fine aggregate and more coarse aggregate, uses less asphalt as a binder, and has a higher void ratio in the pavement. Specifically, it is a mixture of water, asphalt, fine aggregate, coarse aggregate, chemical admixtures, and hardening regulators in a specified ratio.

＜別の舗装構造＞
次に、図２を参照しつつ、本発明の一実施形態における別の舗装構造について、上述した図１に示す舗装構造と相違する部分を説明し、同等の部分の説明を省略する。図２で示した部品又は部位と同等なものは、参照を容易にするため、図２では図１において一律１００を加えた番号にしている。 <Another pavement structure>
Next, with reference to Figure 2, another pavement structure according to one embodiment of the present invention will be described in terms of the differences from the pavement structure shown in Figure 1 described above, and a description of the equivalent parts will be omitted. For ease of reference, parts or portions equivalent to those shown in Figure 2 are numbered by adding 100 to the numbers in Figure 1.

図２に示すように、密粒度アスファルト部１００は、車両の駆動輪である前輪及び後輪周辺に位置し、具体的には、車両の横幅と略同等かつ縦幅と同等又はこれ以上の範囲に渡っている。透水性アスファルト部２００は、車両の左右の乗降口周辺に位置し、具体的には、車両Ｃの駆動輪より外側かつ密粒度アスファルト部１００の縦幅と同等の範囲に渡っている。換言すれば、密粒度アスファルト部１００は、車両の下側かつ車両の投影面積と略同等の範囲に渡って位置し、透水性アスファルト部２００は、車両の外側かつ縦幅と略同等の範囲に渡って位置している。 As shown in FIG. 2, the dense-graded asphalt section 100 is located around the front and rear wheels, which are the drive wheels of the vehicle, and specifically, spans an area approximately equal to the width of the vehicle and equal to or greater than its vertical width. The water-permeable asphalt section 200 is located around the left and right entrances and exits of the vehicle, and specifically, spans an area outside the drive wheels of vehicle C and equal to the vertical width of the dense-graded asphalt section 100. In other words, the dense-graded asphalt section 100 is located below the vehicle and over an area approximately equal to the projected area of the vehicle, and the water-permeable asphalt section 200 is located outside the vehicle and over an area approximately equal to its vertical width.

この構成によれば、車両が密粒度アスファルト部１００内を走行したり旋回したりするため、車両の駆動輪が前輪駆動でも後輪駆動でも、車両の縦幅が長めでも短めでも、密粒度アスファルト部１００を摩耗しにくく、また、車両の左右の乗降口が透水性アスファルト部２００に沿っているため、雨天時でも車両に乗ったり車両から降りたりしやすい効果を期待できる。 With this configuration, the vehicle runs and turns within the dense-grained asphalt section 100, so the dense-grained asphalt section 100 is less likely to wear out, regardless of whether the vehicle's drive wheels are front-wheel drive or rear-wheel drive, and whether the vehicle's vertical width is long or short. In addition, because the left and right boarding and alighting doors of the vehicle are aligned along the water-permeable asphalt section 200, it is expected that it will be easy to get on and off the vehicle even in rainy weather.

なお、本実施形態に示した舗装構造は、上述した内容に限定されず、同等の効果を得られる限り、あらゆる部位の位置・形状・寸法や、部位同士の関係を含む。 The pavement structure shown in this embodiment is not limited to the above, but includes the position, shape, and dimensions of all parts, as well as the relationships between parts, as long as the same effect is obtained.

J Civil Environ Eng 7: 288. doi: 10.4172/2165-784X. 1000288 Page 2 of 15 To comply with the US EPA requirements, transportation agencies must install storm water best management practices (BMPs) to capture and treat storm water runoff from road surface. Road storm water runoff that is collected using engineered drainage system is typically treated to remove pollutants prior to discharge into streams or rivers and lakes or use to recharge groundwater by subsurface infiltration.
