The concrete pavement is composed of permeable concrete for surface layer having a permeability coefficient equivalent to that of drained asphalt pavement in the surface layer, and permeable concrete for base layer having a bending strength equivalent to that of general pavement concrete in the base layer.

표층용 투수콘크리트 포장의 실시배합은 플라이애시 치환율 20%에 대해서 고로슬래그 치환율을 5%, 10%, 20%, 30%로 변화시켰으며 재생골재는 비중 2.25이며 굵은골재 최대치수 20mm이하인 것을 적용하였으며, 쇄석골재는 비중 2.64이며 입도범위 5∼10mm인 골재를 적용하여 각각의 배합을 설정하였다.For the blending of permeable concrete pavement for surface layer, the blast furnace slag substitution rate was changed to 5%, 10%, 20%, and 30% for the fly ash substitution rate of 20%, and the recycled aggregates had a specific gravity of 2.25 and a coarse aggregate of less than 20mm. , The crushed aggregate was 2.64 specific gravity, and the aggregates were set by applying the aggregate of 5 ~ 10mm particle size.

기층용 투수콘크리트 포장의 실시배합은 설계공극율 10%에 대해서 물시멘트비를 20%, 25%, 30%, 35%로 변화시키면서 적용골재는 비중 2.25이며 굵은골재 최대치수 10mm이하인 재생골재와 비중 2.64이며 입도범위 5∼10mm의 쇄석골재를 사용하여 각각의 배합을 설정하였다.The actual mixing of basement permeable concrete pavement is water aggregate ratio of 20%, 25%, 30%, and 35% with respect to 10% of design porosity, while the applied aggregate is 2.25, the coarse aggregate is less than 10mm of coarse aggregate, and the specific gravity is 2.64. Each mixture was set using a crushed stone aggregate having a particle size range of 5 to 10 mm.

다기능성 혼합형 투수콘크리트 포장의 시험방법으로는 휨강도는 15×15×55cm 몰드를 이용하여 진동테이블에 의한 소정의 밀도로 다짐을 하며 KS F 2407, 2408 [콘크리트의 휨강도시험방법]에 준하여 시험하였으며, 투수계수는 JCI에코콘크리트연구위원회 [포러스콘크리트의 투수시험방법(안)]에 준하며 수두차는 12.5cm로 하였다. 내마모성 시험은 골재시험용 Los Angels 시험기 안에 0.3∼5mm의건조한 모래 30kg과 지름이 47.5mm인 강구(무게 438g)를 6개씩 넣고 직경 100mm, 두께 63.5mm의 원주형공시체를 제작하여 양생후 공시체를 시험기의 드럼내부에 넣은 후 매분 30∼33회로 300회를 돌린 후에 공시체의 질량을 측정하여 중량손실을 측정하였다.As a test method of multifunctional mixed permeable concrete pavement, the bending strength was compacted to a predetermined density by vibrating table using a mold of 15 × 15 × 55cm, and tested according to KS F 2407, 2408 [Bending strength test method of concrete]. Permeability coefficient was in accordance with JCI Eco Concrete Research Committee [Performance Test Method of Porous Concrete] and head difference was 12.5cm. The abrasion resistance test was performed by putting 30 kg of dry sand of 0.3 to 5mm and 6 steel balls (weight 438g) of 47.5mm in diameter into a Los Angels tester for aggregate test, and then preparing cylindrical specimens of 100mm diameter and 63.5mm thickness. After putting the drum into the drum 30 times to 30 to 33 times per minute, the weight of the specimen was measured to determine the weight loss.

휨강도시험결과 플라이애시를 치환한 경우의 휨강도는 치환율이 증가함에 따라 다소 저하하는 경향을 보이고 있으나 치환율 30%이내에서는 목표치를 만족시키고 있다. 또한 고로슬래그 잔골재는 이번 시험범위내에서는 휨강도의 저하가 확인되지는 않았다. 투수계수 공극률이 15%정도에서는 치환율과는 관계없이 기준항목을 만족하며, 마모시험 결과 치환율이 증가함에 따라 손실율이 증가하였으나 20%정도의 치환율에서는 기준치를 만족하는 것으로 나타났으며, 병용한 경우에서는 산업부산물을 첨가하지 않은 경우에는 동등한 물성을 만족하는 플라이애시 치환율을 20%로 고정하여 고로슬래그 잔골재의 치환율이 20%이내에서는 각 기준값을 만족하는 결과를 나타내고 있다.As a result of the flexural strength test, the flexural strength of the fly ash substituted tended to decrease as the substitution rate increased, but the target value was satisfied within 30% of the substitution rate. In addition, the blast furnace slag fine aggregate was not found to decrease the flexural strength within this test range. The permeability coefficient was about 15%, which satisfies the criteria regardless of the substitution rate.As a result of the abrasion test, the loss rate increased as the substitution rate was increased, but when the substitution rate was about 20%, the standard value was satisfied. When the industrial by-product is not added, the fly ash substitution rate that satisfies the equivalent physical properties is fixed to 20%, and the replacement rate of the blast furnace slag fine aggregate is within 20%, which satisfies each reference value.

포장용콘크리트의 내구성을 평가하기 위한 목적으로 기층투수성콘크리트의 휨파괴시험을 실시하였다. 공시체는 10×10×50cm, 재하방법은 상한하중을 휨강도비(응력비)를 60% 및 70%로 하여 정현파 5Hz 3등분점 방법으로 하였다. 또한 공용시의 간극수의 영향을 고려하여 함수상태의 공시체를 비닐필름으로 피복한 상태에서 시험을 행하였다. 공시체 3개의 파괴회수(파단회수)의 대수평균을 파괴수명으로 하였다. 각 공시체의 파괴회수는 응력비 60%의 공시체 3개 모두다 220만회에서 파괴되었으며, 응력이 70%의 공시체는 2개가 150만회에서, 1개는 180만회에서 파괴되는 결과를 보이고 있다. 기층 투수성 콘크리트의 파괴수명은 같은 시험조건으로 실시한 포장용포러스콘크리트공통시험에 의한 통상의 포장용콘크리트에 비해 동등 이상의 결과를 나타내었다.For the purpose of evaluating the durability of paving concrete, the flexural failure test of the base permeable concrete was conducted. The specimens were 10 × 10 × 50cm, and the loading method was the sine wave 5Hz third point method with the upper limit load being 60% and 70% of flexural strength ratio (stress ratio). In addition, the test was carried out in a state in which the water-containing specimen was coated with a vinyl film in consideration of the influence of the gap number in common use. The logarithmic average of the three fractures (breaks) was used as the failure life. The failure times of each specimen were destroyed at 2.2 million times in all three specimens with a stress ratio of 60%, and two specimens with 70% stress were destroyed at 1.5 million times and one at 1.8 million times. The fracture life of the base permeable concrete showed more than equivalent results to the normal paving concrete by the common test for paving concrete under the same test conditions.

골재비산저항성, 내마모성등의 노면 공용성을 평가하기 위한 목적으로 현장채취한 공시체를 이용하여 마모시험, 회전휠트랙킹시험, 왕복체인라벨링시험 시험을 하였다.Abrasion test, rotary wheel tracking test, and reciprocating in-vehicle labeling test were conducted using specimens collected on-site for the purpose of evaluating the road commonality such as aggregate scattering resistance and abrasion resistance.

여기에서 채취한 공시체의 공재비산 저항성 결과를 살펴보면, 투수성콘크리트 포장의 공용성능은 배수성아스콘 포장과 비교하여 동등이상의 우수한 결과를 나타내고 있어 산업부산물의 유효활용 및 환경을 배려한 광범위한 적용이 가능한 것이다.Looking at the results of the specimen scattering resistance of the test specimens collected here, the common performance of the water-permeable concrete pavement showed an equivalent or better result than the drainable ascon pavement.

이와 같이 본 발명은 산업부산물인 고순도 플라이애시, 고로슬래그와 강도 및 인성증대는 물론 우수한 균열억제 효과 및 내력확보가 가능하도록 메쉬형 폴리프로필렌단섬유, 내알칼리성 유리단섬유를 이용하여 물리·역학적 특성 및 내구성이 우수한 다기능성 혼합용 투수콘크리트 포장을 제조하므로써 기존 투수콘크리트의 성능이나 기능을 만족시키면서 주행안정성, 수자원의 확보 및 교통소음의 저감에 효과가 있는 것으로 향후 그 적용분야의 확대 및 유효이용 측면에서 전망이 밝은 발명인 것이다.As described above, the present invention is a physical and mechanical properties using high purity fly ash, blast furnace slag, industrial by-products, mesh type polypropylene short fiber, alkali resistant glass short fiber to increase strength and toughness, as well as excellent crack suppression effect and proof strength.
