舗装道路に用いられるアスファルト混合物は舗装道路に水が溜るのを防止するため透水性が大きいことが必要である。舗装道路のアスファルト混合物に対する性能評価のための試験方法は ＪＩＳ Ａ １２１８ 土の透水試験方法に規定され、そして透水試験を行う試験器具についてはその一例が平成１９年６月、社団法人日本道路協会、「舗装調査・試験法便覧」第（３〕−１２０頁に示されている。該舗装調査・試験法便覧に示されている透水試験器はアスファルト混合物の供試体を配置させかつ給水を流通させる多孔性底板を有する透水円筒と、該透水円筒に水密的に結合させかつ上部からの給水を越流させる越流口を備えた透水円筒カラーと、透水円筒を支持するための支持脚と、前記透水円筒と透水円筒カラーを備えた支持脚を配置させかつ透水円筒の多孔性底板から流出した給水を排出させる測定水取出し口を備えた越流水槽とから構成されている。   The asphalt mixture used for paved roads needs to have high water permeability to prevent water from accumulating on the paved roads. The test method for performance evaluation of asphalt mixture on paved roads is defined in JIS A 1218 soil permeability test method, and an example of test equipment for conducting a permeability test is June, Japan Road Association, “Pavement Survey / Test Method Handbook”, page (3) – page 120. The permeability tester shown in the Pavement Survey / Test Method Handbook arranges specimens of asphalt mixture and distributes water. A water permeable cylinder having a porous bottom plate, a water permeable cylindrical collar provided with an overflow port that is watertightly coupled to the water permeable cylinder and overflows water from above, a support leg for supporting the water permeable cylinder, It consists of a water permeable cylinder and an overflow water tank with a measuring water outlet that has a support leg with a permeable cylindrical collar and discharges the feed water flowing out from the porous bottom plate of the permeable cylinder. .

従来技術の透水試験器は透水円筒に透水円筒カラーを水密的に結合させるために、透水円筒から透水円筒カラーを取り外すのに時間がかかり、次のアスファルト混合物の試験を行うのに透水円筒から透水円筒カラーを取り外すのが煩わしい作業となっており、また透水円筒カラーからの給水の注入圧力を変えることができるように水槽の測定取出し口と透水円筒カラーの越流口との高さを可変できる構造を有していない。   The prior art permeability tester takes time to remove the permeable cylinder collar from the permeable cylinder in order to tightly couple the permeable cylinder collar to the permeable cylinder, and from the permeable cylinder to the next asphalt mixture test. Removing the cylindrical collar is a cumbersome task, and the height of the measurement outlet of the water tank and the overflow outlet of the permeable cylindrical collar can be varied so that the water injection pressure from the permeable cylindrical collar can be changed. Does not have a structure.

本発明の目的は透水円筒モールドに透水円筒カラーを簡単に着脱させかつ確実に水密結合させると共に透水円筒カラーの越流口と水槽の測定水取出し口との高さを可変できる構造を備えたアスファルト混合物の室内透水試験器を提供することにある。   An object of the present invention is to provide an asphalt having a structure in which a water-permeable cylindrical collar is easily attached to and detached from a water-permeable cylindrical mold, and is securely connected in a watertight manner, and the height of the overflow port of the water-permeable cylindrical collar and the measured water outlet of the water tank can be varied. An object is to provide an indoor water permeability tester for the mixture.

本発明によるアスファルト混合物の室内透水試験器は測定水取出し口を有する越流水槽と、越流口を有する透水円筒カラーと、アスファルト混合物の供試体を配置させる透水円筒モールドと、水槽の底面に配置させる支持脚とから構成され、水槽の測定水取出し口と透水円筒カラーの越流口との高さを可変できるように高さ調整可能にした支持脚に透水円筒モールドを着脱可能に支持させ、透水円筒カラーをＯリングを介在させて透水円筒モールドに嵌合し、固定スプリングにより透水円筒カラーを透水円筒モールドに着脱可能に締付け固定したものである。   The indoor permeation tester for asphalt mixture according to the present invention includes an overflow tank having a measurement water outlet, a permeable cylindrical collar having an overflow opening, a permeable cylindrical mold for placing a specimen of the asphalt mixture, and a bottom surface of the tank. The permeable cylindrical mold is detachably supported on the support legs that are adjustable in height so that the height of the measurement water outlet of the water tank and the overflow outlet of the permeable cylindrical collar can be varied. The permeable cylindrical collar is fitted into the permeable cylindrical mold with an O-ring interposed, and the permeable cylindrical collar is detachably fastened and fixed to the permeable cylindrical mold by a fixing spring.

本発明は固定スプリングにより透水円筒カラーを透水円筒モールドに締付け固定するものであるから、透水円筒カラーと透水円筒モールドとの着脱が容易であり、またＯリングを介在させて透水円筒カラーを透水円筒モールドに固定するものであるから、漏水することのない確実な水密結合が得られ、更に支持脚に備えた高さ調整スリーブを介して透水円筒モールドを支持脚に支持させるものであるから、透水円筒カラーからの給水の注入圧力を変えることができるように水槽の測定水取出し口と透水円筒カラーの越流口との高さを簡単に可変調整することができる。   In the present invention, the permeable cylindrical collar is fastened and fixed to the permeable cylindrical mold by the fixing spring, so that the permeable cylindrical collar and the permeable cylindrical mold can be easily attached to and detached from each other, and the permeable cylindrical collar is inserted into the permeable cylindrical through an O-ring. Since it is fixed to the mold, a reliable watertight connection without water leakage is obtained, and the permeable cylindrical mold is supported on the support leg via a height adjustment sleeve provided on the support leg. The height of the measured water outlet of the water tank and the overflow port of the permeable cylindrical collar can be easily variably adjusted so that the injection pressure of the water supply from the cylindrical collar can be changed.
